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