Abstract: A method of encoding a digital video data applies adaptive pre-processing to data representing high dynamic range (HDR) and/or wide color gamut (WCG) image data prior to encoding and complementary post-processing to the data after decoding in order to allow at least partial reproduction of the HDR and/or WCG data. The example methods apply one or more color space conversions, and a perceptual transfer functions to the data prior to quantization. The example methods apply inverse perceptual transfer functions and inverse color space conversions after decoding to recover the HDR and/or WCG data. The transfer functions are adaptive so that different transfer functions may be applied to video data sets including different groups of frames, frames or processing windows in a single frame. Information on the data set and information on the applied transfer function is passed as metadata from the encoder to the decoder.

Abstract: Moving image data of a wide viewing angle image is divided into blocks to obtain a coding target block. A motion-compensated reference block is extracted for each coding target block. The reference block is subjected to adjustment processing of rotation and/or scaling. A residual signal is calculated on the basis of a pixel value of the coding target block and a pixel value of the reference block subjected to the adjustment processing for each coding target block, and the residual signal of the coding target block is coded to obtain an encoded stream. Adjustment processing information is inserted into the encoded stream together with the motion vector for each coding target block. The residual can be reduced, the coding bit rate can be reduced, and consequently the coding performance of motion prediction can be improved.
