Specific embodiment
The present invention provides a kind of control method and mobile terminal of camera module output image resolution, to make the present invention's
Purpose, technical scheme and effect are clearer, clear and definite, and the present invention is described in more detail below.It should be appreciated that this place is retouched
The specific embodiment stated only to explain the present invention, is not intended to limit the present invention.
As shown in figure 1, a kind of control method of camera module output image resolution in the specific embodiment of the invention, described
Method is comprised the following steps：
S100, acquisition user input operation, and it is converted into corresponding output image resolution.
The resolution of output image resolution described in S200, comparison and the output image of camera module current setting whether phase
Together；If identical, execution step S400；If it is different, then execution step S300.
S300, the resolution of camera module output image is set to into the output image resolution.
S400, output image.
When being embodied as, before step S100, the control method also includes：Obtain from camera module supplier in advance
And setting sequence corresponding with various output image resolution described in storing.Specifically, mobile terminal can also open setting sequence
The write authority of row, the resolution for alloing user to need according to itself, write are correspondingly arranged sequence and store, so that mobile
Terminal can be according to the individual demand of user, there is provided corresponding output image resolution and be not limited to factory setting.
Wherein, each arranges sequence and is correspondingly arranged a kind of output image resolution.The setting sequence is a string 16
Binary data, output image resolution are one-to-one relationship with sequence is arranged.The selection of output image resolution, the kind of adjustment
Class and corresponding setting when sequence is dispatched from the factory by mobile terminal preset.
Specifically, step S300 is specifically included：Setting sequence corresponding with the output image resolution is obtained first；
The setting sequence is write in camera module by digital communication interface afterwards, the resolution for making camera module output image is
The output image resolution.The present invention can conveniently, efficiently change photographing unit by way of write is correspondingly arranged sequence
Output image resolution, realize according to user operation adjust camera module output image resolution.
It is preferred that camera module is when output meets the image of user's request resolution, while by ultimate resolution figure
As exporting and preserving into a certain specific memory.When user is in the behaviour that preview is finished or other required image resolution are relatively low
After work, further artwork can also be modified, process, without losing ultimate resolution image.
Specifically, the present invention can also be used to change output image resolution using directly increasing by one in photographing unit key-course
The interface of rate, directly changes the resolution of camera module output image according to user operation instruction by the interface.Should illustrate
, in other embodiments, it would however also be possible to employ any other suitably changes the method reality of camera module output image resolution
The now control to output image resolution.
Further, the control method of camera module output image resolution of the invention, after step S300,
Also include：Camera module output resolution ratio and the output image resolution identical image are received, for grasping with the user
Make corresponding back-end function.
The view data of camera module output, is used directly for the other functions of rear end, compared with prior art, this
The view data that camera module is exported is converted to the resolution that corresponding rear end needs by the bright image processing algorithm that needs not move through
After the view data of rate, could be used by rear end, so as to effectively improve the speed of mobile terminal calculation process, it is to avoid tired
Miscellaneous computing.
As shown in Fig. 2 the present invention correspondingly provides a kind of output image, which includes：
Input module 100, resolution acquisition module 200, resolution comparison module 300, camera module 400 and sequence are arranged
Module 500.The input module 100, resolution acquisition module 200, resolution comparison module 300 and sequence setup module 500
It is sequentially connected, sequence setup module 500 connects the camera module 400 of mobile terminal.
Wherein, input module 100 is used to obtain user operation, and the input module is keyboard, touch screen etc., the user
Operate the operational order by the input of the modules such as keyboard, touch screen for user.
Resolution acquisition module 200 is for changing into corresponding output image resolution by the user operation of acquisition.For example,
It is 640 × 480 that input module 100 obtain user to change preview resolution size, then the resolution that resolution acquisition module 200 is obtained
Rate value is 640 × 480；Again for example, it is 2048 × 1536 that input module 100 obtain user to change resolution sizes of taking pictures, then divide
When user takes camera button, the resolution value for obtaining is 2048 × 1536 to resolution acquisition module 200.
It is defeated with 400 current setting of camera module that resolution comparison module 300 is used for the comparison output image resolution
Go out the resolution of image.Sequence setup module 500, for when the output image resolution and 400 output image of camera module
When resolution is differed, the resolution of 400 output image of camera module is set to into the output image resolution, so that shining
400 output image resolution of phase module is identical with the output image resolution.When the output image resolution and photograph mould
When 400 output image resolution of block is identical, it is not operate, direct output image.
Specifically, as shown in figure 3, sequence setup module 500 is connected by I2C digital communication interfaces with camera module 400
Connect, the I2C_SCL ends of sequence setup module 500 connect the CSCL ends of photographing unit, the I2C_SDA ends of sequence setup module 500 connect
Connect the CSDA ends of photographing unit.
It is preferred that as shown in Fig. 2 the mobile terminal also includes：Sequence memory module 600, which arranges mould with sequence
Block 500 connects, for storing various output image resolution setting sequence corresponding with 400 output image of camera module.Wherein,
The setting sequence is by camera module 400（Such as photographic head）Supplier provides, and which includes that output image resolution is corresponding
Sequence.The resolution acquisition module 200, being additionally operable to obtain in advance camera module 400, to export various image in different resolution corresponding
Sequence is set, and is stored in sequence memory module 600.
Further, the resolution acquisition module 200, is additionally operable to obtain set corresponding with the output image resolution
Put sequence.The sequence setup module 500 is additionally operable to from sequence memory module 600 call 400 supplier of camera module advance
The setting sequence corresponding with resolution for providing, is write the setting sequence in camera module 400 by digital communication interface,
The resolution for making 400 output image of camera module is the output image resolution, even if the output of camera module 400 and the resolution
The corresponding view data of rate size.
Specifically, as shown in Fig. 2 the mobile terminal also includes view data receiver module 700, connect the photograph mould
Block 400, for receiving 400 output resolution ratio of camera module and the output image resolution identical image, and is applied
In respective rear ends function.View data receiver module 700 receives the output image data for obtaining, and is used directly for rear end its
His function, the view data without resolution required for corresponding rear end is converted to by image processing algorithm, effectively
Improve the speed of mobile terminal calculation process, it is to avoid miscellaneous computing.
