VIDEO COMPRESSION METHOD AND APPARATUS TO SUPPORT CONTENT BACKGROUND LUMINANCE-ADAPTIVE OPTO-ELECTRIC/ELECTRO-OPTIC TRANSFER FUNCTIONS

摘要

The present invention is a video encoding method supporting brightness adaptive photoelectric/electrical conversion, and in a video encoding method supporting brightness adaptive photoelectric/electrical conversion, inter-frame prediction between frames preprocessed through different photoelectric conversion functions for each frame However, in performing inter-screen prediction after conversion to an optical signal, the inverse function of the photoelectric conversion function applied to the reference frame is applied to restore the signal in the optical signal region by applying the electro-optical conversion function, and the inverse function of the photoelectric conversion function applied to the current frame An electro-optical conversion function is applied to restore a signal in the optical signal region, and inter-screen prediction can be performed in the optical signal region.
