Step 102: the projection mode is adjusted based on the visual and/or environmental features.
In some embodiments, a contrast between the projection surface and the projection content may be detected, and when the contrast between the projection surface and the projection content does not satisfy a contrast condition, the projection parameters of the pictures and/or the texts in the projection content are adjusted, so that the adjusted projection content and the projection surface satisfy the contrast condition.
The contrast condition may be that the contrast is greater than a preset threshold, where the preset threshold may be defined according to a degree of definition of the projection content when the projection content is projected onto the projection surface, and generally, the greater the contrast, the clearer and more noticeable the projection content.
In some embodiments, adjusting the projection mode may include: and adjusting projection parameters of pictures and/or characters in the projection content, wherein the projection parameters can comprise brightness parameters and color parameters.
Step 103: and projecting the projection content to the projection surface based on the projection mode so that the contrast condition between the projection content and the projection surface is met.
And under the adjusted projection mode, projecting the projection content to the projection surface so as to enable the projection content and the projection surface to meet the contrast condition, thereby enabling the projection content to be clearly displayed on the projection surface.
Therefore, by adopting the scheme, the projection mode can be adjusted by combining the visual characteristics of the projection surface and/or the environmental characteristics of the projection equipment when the projection content is projected, and the projection content is projected to the projection surface in the adjusted projection mode. In this way, automatic adjustment of the projection mode by the visual features and/or the environmental features is achieved, ensuring that the contrast achieved in any case enables the user to see the projected content clearly.
Example II,
An embodiment of the present invention provides a projection processing method, as shown in fig. 2, the method includes:
step 201: the visual characteristics of the projection surface and the environmental characteristics of the projection device when the projection device projects the content are detected.
Here, the projection device may be an electronic device having a projection function, such as a projector. Detecting visual characteristics of the projection surface may include: the color parameters and the light reflection degree of the projection surface are detected, an image acquisition unit such as a camera and a camera can be arranged in the electronic equipment, the image of the projection surface is acquired through the image acquisition unit, the color components of all pixel points in the image of the projection surface are analyzed, and the color parameters of the projection surface are determined based on the color components.
In some embodiments, detecting an environmental feature in which the projection device projects content may include: the light brightness in the environmental characteristics is detected, and various sensors such as optical sensors can be built in the electronic device to detect the current light brightness when the content is projected.
Step 202: based on the visual features, the projection mode is adjusted.
In some embodiments, a contrast between the projection surface and the projection content may be detected, and when the contrast between the projection surface and the projection content does not satisfy a contrast condition, the projection parameters of the pictures and/or the texts in the projection content are adjusted, so that the adjusted projection content and the projection surface satisfy the contrast condition.
The contrast condition may be that the contrast is greater than a preset threshold, where the preset threshold may be defined according to a degree of definition of the projection content when the projection content is projected onto the projection surface, and generally, the greater the contrast, the clearer and more noticeable the projection content.
In some embodiments, adjusting the projection mode based on the visual characteristic may include:
when the color parameter of the projection surface is smaller than the first dark color threshold value, the color parameter of the picture and the characters in the projection content is adjusted to be larger than the second light color threshold value, and/or the projection brightness parameter is adjusted to be larger than the brightness threshold value, wherein the first dark color threshold value is smaller than the second light color threshold value, and the brightness threshold value can be set according to a brightness which can enable human eyes to perceive from the projection surface.
Here, after the image of the projection plane is acquired by the image acquisition unit, the color components of red, green and blue (R, G, B) of N pixels in the image of the projection plane may be determined, and if R, G, B components of all pixels are smaller than the first dark color threshold, or R, G, B components of ninety percent of the pixels are smaller than the first dark color threshold, for example, the first dark color threshold may be 30, the color of the projection plane is determined to be a particularly dark color, for example, black.
Because the color parameter of the projection surface is less than the first dark color threshold, that is, when the color of the projection surface is particularly dark, for example, black, in order to increase the contrast between the projection content and the projection surface, the colors of both the pictures and the texts in the projection content may be adjusted to be greater than the second light color threshold, for example, white, and at the same time, the projection brightness may be enhanced in combination with the brightness of the light in the current environmental characteristic, and the projection brightness parameter may be adjusted to be greater than the brightness threshold.
For example, the original projection content includes characters and icons in various colors, and after the electronic device (projector) determines that the color of the projection surface is black, referring to fig. 3, the colors corresponding to the icons in the projection content may all be adjusted to white, the characters in the projection content may also all be adjusted to white, the left and right buttons of the screen may also be adjusted to white, and meanwhile, the projection brightness may be enhanced in combination with the brightness of the light in the current environmental characteristic, and the projection brightness parameter may be adjusted to a parameter greater than the brightness threshold.
By adjusting the projection color parameter and the brightness parameter based on the visual characteristics, the contrast condition between the adjusted projection content and the projection surface can be met. Therefore, the purpose that the user can see the projection content clearly with the maximum effect is achieved.
Step 203: and projecting the projection content to the projection surface based on the projection mode so that the contrast condition between the projection content and the projection surface is met.
And under the adjusted projection mode, projecting the projection content to the projection surface so as to enable the projection content and the projection surface to meet the contrast condition, thereby enabling the projection content to be clearly displayed on the projection surface.
Therefore, by adopting the scheme, the projection mode can be adjusted by combining the visual characteristics of the projection surface and/or the environmental characteristics of the projection equipment when the projection content is projected, and the projection content is projected to the projection surface in the adjusted projection mode. In this way, automatic adjustment of the projection mode by the visual features and/or the environmental features is achieved, ensuring that the contrast achieved in any case enables the user to see the projected content clearly.
Example III,
An embodiment of the present invention provides a projection processing method, as shown in fig. 4, the method includes:
step 401: the visual characteristics of the projection surface and the environmental characteristics of the projection device when the projection device projects the content are detected.
Here, the projection device may be an electronic device having a projection function, such as a projector. Detecting visual characteristics of the projection surface may include: the color parameters and the light reflection degree of the projection surface are detected, an image acquisition unit such as a camera and a camera can be arranged in the electronic equipment, the image of the projection surface is acquired through the image acquisition unit, the color components of all pixel points in the image of the projection surface are analyzed, and the color parameters of the projection surface are determined based on the color components.
Detecting environmental characteristics of the projection device when projecting content may include: the light brightness in the environmental characteristics is detected, and various sensors such as optical sensors can be built in the electronic device to detect the current light brightness when the content is projected.
Step 402: based on the visual and environmental features, the projection mode is adjusted.
In some embodiments, a contrast between the projection surface and the projection content may be detected, and when the contrast between the projection surface and the projection content does not satisfy a contrast condition, the projection parameters of the pictures and/or the texts in the projection content are adjusted, so that the adjusted projection content and the projection surface satisfy the contrast condition.
The contrast condition may be that the contrast is greater than a preset threshold, where the preset threshold may be defined according to a degree of definition of the projection content when the projection content is projected onto the projection surface, and generally, the greater the contrast, the clearer and more noticeable the projection content.
In some embodiments, adjusting the projection mode based on the visual and environmental features may include: when the color parameter of the projection surface is larger than the first dark color threshold and smaller than the third dark color threshold, the color parameter of the characters in the projection content is adjusted to be larger than the second light color threshold, wherein the first dark color threshold is smaller than the third dark color threshold, and the third dark color threshold is smaller than the second light color threshold, and/or the color parameter of at least part of pictures in the projection content is adjusted to be different from the color parameter of the projection surface.
Here, after the image of the projection plane is acquired by the image acquisition unit, color components of red, green, and blue (R, G, B) of N pixels in the image of the projection plane may be determined, and if R, G, B components of all pixels are greater than the first dark color threshold and smaller than the third dark color threshold, or R, G, B components of ninety percent pixels are greater than the first dark color threshold and smaller than the third dark color threshold, for example, the first dark color threshold may be 30, and the third dark color threshold may be 100, the color of the projection plane is determined to be dark color, for example, dark gray.
Since the color parameter of the projection surface is greater than the first dark color threshold and less than the third dark color threshold, i.e. the projection surface is dark in color, e.g. dark gray, in order to increase the contrast between the projection content and the projection surface, the color of the text in the projected content may be adjusted to a parameter larger than the second light threshold, for example, white, in order to not affect the color effect of the projected content to the maximum extent, the color parameters of at least part of the pictures in the projection content can be adjusted to be different from those of the projection surface, and in short, the color of the projection content characters can be adjusted to be white, and/or the color parameters of the dark gray picture included in the projection content can be adjusted to be any color parameters except for dark gray, so that the problem that the projection content cannot be seen due to overlapping caused by the fact that at least part of the color parameters of the projection content are the same as those of the projection surface is avoided.
For example, the original projection content includes characters and icons of various colors, and after the electronic device (projector) determines that the color of the projection surface is dark gray, referring to fig. 5, the characters in the projection content can be all adjusted to white, the color corresponding to the icon in the same color as the projection surface in the projection content can be adjusted to a color other than dark gray, and the other icons other than dark gray remain unchanged.
In some embodiments, adjusting the projection mode based on the visual and environmental features may further include:
when the brightness of the light in the environmental characteristic is smaller than the darkness threshold value, the projection brightness parameter is adjusted to be a parameter larger than the brightness threshold value, wherein the darkness threshold value is smaller than the brightness threshold value, and the brightness threshold value and the darkness threshold value can be set according to a brightness and darkness which are needed by human eyes to sense from the projection surface.
By adjusting the projection color parameter and the brightness parameter based on the visual characteristic and the environmental characteristic, the contrast condition between the adjusted projection content and the projection surface can be met. Therefore, the purpose that the user can see the projection content clearly with the maximum effect is achieved.
Step 403: and projecting the projection content to the projection surface based on the projection mode so that the contrast condition between the projection content and the projection surface is met.
And under the adjusted projection mode, projecting the projection content to the projection surface so as to enable the projection content and the projection surface to meet the contrast condition, thereby enabling the projection content to be clearly displayed on the projection surface.
Therefore, by adopting the scheme, the projection mode can be adjusted by combining the visual characteristics of the projection surface and/or the environmental characteristics of the projection equipment when the projection content is projected, and the projection content is projected to the projection surface in the adjusted projection mode. In this way, automatic adjustment of the projection mode by the visual features and/or the environmental features is achieved, ensuring that the contrast achieved in any case enables the user to see the projected content clearly.
Example four,
An embodiment of the present invention provides a projection processing method, as shown in fig. 6, the method includes:
step 601: the visual characteristics of the projection surface and the environmental characteristics of the projection device when the projection device projects the content are detected.
Here, the projection device may be an electronic device having a projection function, such as a projector. Detecting visual characteristics of the projection surface may include: the color parameters and the light reflection degree of the projection surface are detected, an image acquisition unit such as a camera and a camera can be arranged in the electronic equipment, the image of the projection surface is acquired through the image acquisition unit, the color components of all pixel points in the image of the projection surface are analyzed, and the color parameters of the projection surface are determined based on the color components.
In some embodiments, detecting an environmental feature in which the projection device projects content may include: the light brightness in the environmental characteristics is detected, and various sensors such as optical sensors can be built in the electronic device to detect the current light brightness when the content is projected.
Step 602: based on the visual and environmental features, the projection mode is adjusted.
In some embodiments, a contrast between the projection surface and the projection content may be detected, and when the contrast between the projection surface and the projection content does not satisfy a contrast condition, the projection parameters of the pictures and/or the texts in the projection content are adjusted, so that the adjusted projection content and the projection surface satisfy the contrast condition.
The contrast condition may be that the contrast is greater than a preset threshold, where the preset threshold may be defined according to a degree of definition of the projection content when the projection content is projected onto the projection surface, and generally, the greater the contrast, the clearer and more noticeable the projection content.
In some embodiments, adjusting the projection mode based on the visual and environmental features may include: and when the color parameter of the projection surface is larger than the second light color threshold value, adjusting the color parameter of the characters in the projection content to be smaller than the first dark color threshold value, wherein the first dark color threshold value is smaller than the second light color threshold value.
Here, after the image of the projection plane is acquired by the image acquisition unit, the color components of red, green and blue (R, G, B) of N pixels in the image of the projection plane can be determined, and if R, G, B components of all pixels are greater than the second light threshold, or R, G, B components of ninety percent of the pixels are greater than the second light threshold, for example, the second light threshold may be 220, the color of the projection plane is determined to be a light color, for example, white.
Since the color parameter of the projection surface is larger than the second light threshold, i.e. the color of the projection surface is light, e.g. white, in order to increase the contrast between the projection content and the projection surface, the colors of the characters in the projection content may all be adjusted to a parameter smaller than the first dark threshold, e.g. black.
For example, the original projection content includes characters and icons of various colors, and after the electronic device (projector) determines that the color of the projection surface is white, referring to fig. 7, the characters in the projection content may be all adjusted to black, or the left and right buttons of the screen may be adjusted to black.
In some embodiments, adjusting the projection mode based on the visual and environmental features may further include:
when the light brightness in the environmental characteristics is smaller than the darkness threshold value, adjusting the projection brightness parameter to a parameter smaller than the darkness threshold value; when the light brightness is larger than the brightness threshold value, the projection brightness parameter is adjusted to be a parameter larger than the brightness threshold value, wherein the darkness threshold value is smaller than the brightness threshold value, and the brightness threshold value and the darkness threshold value can be set according to the brightness and the darkness which can enable human eyes to sense the needed brightness and darkness from the projection surface.
By adjusting the projection color parameter and the brightness parameter based on the visual characteristic and the environmental characteristic, the contrast condition between the adjusted projection content and the projection surface can be met. Therefore, the purpose that the user can see the projection content clearly with the maximum effect is achieved.
Step 603: when the text in the projected content includes a background, the background is hidden.
When the content is projected, the characters in the projected content are detected to comprise the background, for example, the background exists under the characters, the background can be hidden or deleted, and the characters are directly projected onto the projection surface only, so that the power consumption is saved.
Step 604: and projecting the projection content to the projection surface based on the projection mode so that the contrast condition between the projection content and the projection surface is met.
And under the adjusted projection mode, projecting the projection content to the projection surface so as to enable the projection content and the projection surface to meet the contrast condition, thereby enabling the projection content to be clearly displayed on the projection surface.
Therefore, by adopting the scheme, the projection mode can be adjusted by combining the visual characteristics of the projection surface and/or the environmental characteristics of the projection equipment when the projection content is projected, and the projection content is projected to the projection surface in the adjusted projection mode. In this way, automatic adjustment of the projection mode by the visual features and/or the environmental features is achieved, ensuring that the contrast achieved in any case enables the user to see the projected content clearly.
