Abstract: The present disclosure relates to a decoding device, a decoding method, an encoding device, and an encoding method, which are capable of enabling a decoding side to accurately recognize a color gamut of an encoding target image. The decoding device includes circuitry configured to receive an encoded stream including encoded data of an image and color primary information indicating a coordinate of at least one color primary of the image. The circuitry extracts the encoded data and the color primary information from the received encoded stream. The circuitry decodes the encoded data to generate the image. Further, the circuitry adjusts a color space of the generated image based on the extracted color primary information. The present disclosure can be applied to, for example, a decoding device of a high efficiency video coding (HEVC) scheme.

Abstract: To resolve or at least reduce trouble related to mismatch between a dynamic range of an HDR video signal and peak luminance of a display. Provided is an image processing apparatus including: a transformation unit configured to transform image signals based on a signal scheme of fixedly handling a display luminance level of reference white into display signals by executing gamma transformation so that the display luminance level of the reference white is maintained using a parameter decided on a basis of a peak luminance level of a display.
