Abstract: A method of performing tone mapping in a stream of images (Fr1 . . . N) includes, for each image (FrN) in the stream: sparsely reading image data values (IDN) corresponding to the image (FrN) to provide sparse image data from a plurality of sparsely distributed positions (Pos1 . . . k) in the image (FrN); generating, based on the sparse image data, tone mapping parameters of a tone mapping algorithm (TMA) for each position in the image (FrN); each position in the image (FrN) including the sparsely distributed positions (Pos1 . . . k) and a plurality of further positions (PosF1 . . . j) in the image (FrN); reading the image data values (IDN) corresponding to the image (FrN) to provide image data from each position in the image (FrN); and tone mapping the image by mapping the image data from each position in the image (FrN) to adjusted image data using the generated tone mapping parameters.

Abstract: A computer-implemented method, a computer system configured to perform the method, and a non-transitory computer-readable storage medium are provided comprising instructions for executing the method are provided. The computer-implemented method comprises obtaining input video data including frames of input image data comprising first image data values expressed in an input color space. The first image data values are processed with a first and second color space conversion process to generate first processed image data and second processed image data respectively. The first processed image data and the second processed image data include image data values expressed in an output color space. Output image data is derived from both the first processed image data and the second processed image data.
