MOVING IMAGE ENCODING DEVICE, MOVING IMAGE DECODING DEVICE, MOVING IMAGE ENCODING METHOD AND MOVING IMAGE DECODING METHOD Russian patent published in 2018 - IPC H04N19/593 H04N19/44 H04N19/91 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Moving image decoding device comprises a variable-length decoding unit of the quantized coefficient, the internal prediction parameter and the motion vector from the bitstream; the inverse quantization of the quantized coefficient; internal prediction image generating unit that includes a luminance signal and a color difference signal to perform an internal prediction process on the target block; external prediction image generating unit for executing an external prediction process on the target block and image addition module for adding an internal prediction image or an external prediction image with a difference image to obtain a decoded image; and prediction image generation unit performs an internal prediction process of the color difference signal over the target block in accordance with the information for generating a color difference signal prediction image.

EFFECT: technical result is to reduce the amount of code associated with the internal prediction mode.
