Image processing

A computer system comprising at least one processor and storage, wherein the storage comprises computer-executable instructions which, when executed by the at least one processor, cause the computer-system to:

• obtain input video data including a sequence of frames of input image data, the input image data comprising first image data values expressed according to an input color space and representing a plurality of pixel locations;
• generate first processed image data comprising second image data values representing the plurality of pixel locations and being expressed according to an output color space, different to the input color space, by processing the input image data using a first color space conversion process;
• generate second processed image data comprising third image data values representing the plurality of pixel locations and being expressed according to the same output color space as the second image data values, the third image data values being generated by processing the input image data using a second color space conversion process, wherein the second color space conversion process uses a different color space conversion function to the first color space conversion process;
• and
• generating output image data by combining the first processed image data and the second processed image data,
• wherein combining the first processed image data and the second processed image data comprises generating fourth image data values representing at least one pixel location by blending, from the first processed image data, second image data values representing the at least one pixel location with, from the second processed image data, third image data values representing the at least one pixel location.

A non-transitory computer-readable storage medium comprising computer-executable instructions which, when executed by one or more processors, cause the one or more processors to perform a process including:

• obtaining input video data including a sequence of frames of input image data, the input image data comprising first image data values expressed according to an input color space and representing a plurality of pixel locations;
• generating first processed image data comprising second image data values representing the plurality of pixel locations and being expressed according to an output color space, different to the input color space, by processing the input image data using a first color space conversion process;
• generating second processed image data comprising third image data values representing the plurality of pixel locations and being expressed according to the same output color space as the second image data values, the third image data values being generated by processing the input image data using a second color space conversion process, wherein the second color space conversion process uses a different color space conversion function to the first color space conversion process;
• and
• generating output image data by combining the first processed image data and the second processed image data,
• wherein combining the first processed image data with the second processed image data comprises generating fourth image data values representing at least one pixel location by blending, from the first processed image data, second image data values representing the at least one pixel location with, from the second processed image data, third image data values representing the at least one pixel location.
