摘要:
This image processing apparatus performs image processing on an image including image data with a negative value, and is provided with: a transformation unit that performs a nonlinear transformation processing on the image including image data with a negative value to transform the image into an image that does not include image data with a negative value; an image processing unit that performs predetermined image processing on the image that does not include image data with a negative value; and an inverse transformation unit that performs an inverse transformation processing of the nonlinear transformation processing on the image, having been subjected to the image processing, which does not include image data with a negative value so as to inversely transform the image into an image, having been subjected to the image processing, which includes image data with a negative value.
摘要:
In the image processing apparatus, Input transform into an input color space is performed on input image data; After the input transform, transform processing of transforming chroma or chromaticity of the input image data or chroma or chromaticity in the input color space is performed so as to reduce a difference between a space of chroma or chromaticity of the input image data and a space of chroma or chromaticity in the input color space to acquire transformed image data; and Output transform into an output color space is performed on the transformed image data using a three-dimensional lookup table including inverse transform processing of returning the chroma or chromaticity of the transformed image data to the chroma or chromaticity of the input image data to acquire output image data.
摘要:
A video conversion unit comprises: a unit which acquires a camera video data signal; a first color conversion unit which converts the camera video data signal to a photography scene reference color space and derives first video data; a lock modification section which carries out a lock modification on the first video data; a second color conversion unit which converts the post-color conversion video data to a video output reference color space and derives second video data; and a third color space conversion unit which converts the second video data to a color space of a verification display device and derives third video data in order to pre-verify a device color which is obtained when converting to a color space of a final video output device with a different display device.
