  The present technology relates to an imaging apparatus that performs RAW imaging and a post-production apparatus that performs post-production on RAW data captured by the imaging apparatus.

  In the video content creation process, which consists of various video scenes that include captured video material, the task of capturing a scene using a camera and the post-processing (post-production process) of the captured image source Are performed sequentially. A content creation system for efficiently performing these operations has been proposed (for example, see Patent Document 1).

  In the content creation system described in Patent Document 1, two types of correction parameters are used in the post-production process, which are a camera setting value set at the time of shooting and an effect correction value for adjusting video. The camera setting value is a setting value at the time of shooting, and includes values for setting each function of the camera such as exposure, white balance, gamma correction, and color adjustment. On the other hand, the effect correction value is a setting value used for correcting a video after shooting in order to obtain a desired image quality. For example, it includes values for adjusting attributes relating to image effects such as exposure, white balance, gamma correction, 3D effect, trimming, and zoom. During post-production processing, correction parameter values set by the user via the operation input unit, correction parameter values set in past editing information stored in the database, and the like are used.

[Processing based on second metadata]
In the present embodiment, in the imaging apparatus 100, EI, an effective marker, and ASC-CDL are set as second metadata that is recommended to be reflected in the development processing of RAW data, and the RAW data and the first metadata are set. The data is transmitted to the post-production device 200 together with the data. Therefore, the imaging apparatus 100 and the post-production apparatus 200 can share the same second metadata, and the image data recommended by the photographer or the imaging supervisor can be reproduced in the post-production field. it can.

  Next, processing based on EI, effective markers, and ASC-CDL will be described. However, the present technology is not characterized by the following processing itself.

(Gain adjustment using EI)
Next, an example of processing based on EI in the imaging device 100 and the post-production device 200 will be described.
In the imaging device 100, the EI acquisition unit 112 of the second metadata acquisition unit 110 receives the measurement value (dB) transmitted from the illuminance meter 113 in a wired or wireless manner in real time, and this is shown in a table shown in FIG. To convert it into an EI (Exposure Index of Photo Meter) value. As shown in the table, EI covers at least a plurality of integer values determined in the range of “200” to “3200”, and “800” is used as a reference value.

In the imaging apparatus 100 and the post-production apparatus 200, the sensitization / desensitization / gain adjustment / color space conversion unit (103, 203) calculates a gain to be applied to the white value of the RAW data by the following equation.
EI / imager sensitivity (1)
Therefore, when the imager sensitivity (ISO Sensitivity) value given as the first metadata is “800” and the EI is “1600”, “2” is the gain value applied to the white value of the RAW data. Desired.

  FIG. 4 is a graph showing gains assigned to image data by the sensitization / desensitization / gain adjustment / color space conversion unit (103, 203). Since the black value of the RAW data is the value when the camera imager 101 is in the shutter-off state, the gain is fixed at “1” because the illuminance dependency can be ignored. When “2” is calculated as the gain value to be applied to the white value of the RAW data by the above calculation method, the value from “1” to “2” with respect to the value of the RAW data in the range from black to white. Range gains are assigned proportionally.

  More specifically, when the black value (fixed value) of RAW Code Value is “512” and the white value (measured value) of RAW Code Value is “2992”, (2992-512) × 2 = 5472 Is the gain-adjusted white value.

  As described above, in the present embodiment, since the EI is transmitted to the post-production device 200 as the second metadata, the brightness that the photographer, the shooting director, and the like are watching on the monitor connected to the imaging device 100 is displayed. This image can be reproduced in the post-production apparatus 200. Thereby, the work efficiency of post-production can be improved.

[Processing using effective markers]
Next, processing based on the effective marker in the imaging apparatus 100 and the post-production apparatus 200 will be described.
The effective marker is metadata intended to express the framing intended by the photographer. As shown in FIG. 5, the effective marker includes an Effective Marker Coverage indicating a reduction ratio (a ratio of long pieces) to the image frame of the payload of the effective area marker, and an Effective Marker Aspect Ratio indicating an aspect ratio of the effective area marker. . The second metadata acquisition unit 110 acquires the value of the marker reduction ratio from the user through the graphical user interface (GUI) 114 and correlates the effective marker coverage and the effective marker aspect ratio with the aspect ratio of the monitor screen. To decide. This effective marker is transmitted as second metadata together with the RAW data and the first metadata to the post-production device 200 by the transmission unit 111.

As illustrated in FIG. 6, in the imaging apparatus 100, the effective marker synthesis unit 108 effects the image 125 displayed on the viewfinder based on the metadata of the effective marker acquired by the second metadata acquisition unit 110. The marker graphics 130 are synthesized and displayed.
On the other hand, in the post-production apparatus 200, the effective marker processing unit 206 cuts out the effective area from the image data based on the metadata of the effective marker acquired by the RAW data / metadata acquisition unit 201, and the extracted image data To the original resolution.

  As described above, the effective marker is transmitted as the second metadata to the post-production device 200, so that the post-production device 200 can quickly perform the cut-out process of the effective area intended by the photographer or the imaging director. be able to. Thereby, the work efficiency of post-production can be improved.

[Color correction based on ASC-CDL]
Next, color correction based on ASC-CDL in the imaging apparatus 100 and the post-production apparatus 200 will be described.

In ASC-CDL, a color is defined for each RGB by three parameters: offset (output value when input is zero), slope (input / output gain), and power (input / output gun marker characteristic). Details of color correction based on ASC-CDL are disclosed in "ASC Color Decision List (ASC CDL) Transfer Functions and Interchange Syntax, ASC-CDL_Release1.2, Joshua Pines and David Reisner, 2009-05-04". Is done.

  In the imaging apparatus 100, the second metadata acquisition unit 110, for example, as shown in FIG. 7, each offset, slope, and power for each RGB given by the user using a graphical user interface (GUI) 114. The values are obtained, and these are grouped together to create an ASC-CDL. In the graphical user interface (GUI) 114 shown in FIG. 7, the offset, slope, and power values for each RGB can be individually selected by the user by operating a slide gauge or an up / down button. The set ASC-CDL is reflected in real time on the image displayed in the image display area 131, so that the user can set the ASC-CDL while confirming the color change of the image.

  This ASC-CDL is transmitted as second metadata together with the RAW data and the first metadata to the post-production device 200 by the transmission unit 111. As a result, the color correction intended by the photographer, the director of photography, etc. can be executed by the second color correction unit 205 of the post-production apparatus 200. As a result, the work efficiency of the post-production can be improved.

The embodiment according to the present technology has been described above, but the present technology can be modified as follows.
It is beneficial to employ wireless communication for communication between the illuminance meter 113 and the imaging device 100. Further, the illuminance meter 113 may be provided integrally with the imaging device 100.
