IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD Russian patent published in 2018 - IPC H04N19/86 H04N19/117 H04N19/593 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Image processing apparatus comprises a filtering processing unit for performing bilinear interpolation filtering of neighbouring pixels when the value, calculated based on neighbouring pixels, is smaller than a threshold value set according to the bit depth of image data, to generate filtered neighbouring pixels; an intra prediction unit for performing intra prediction processing for the current block using filtered neighbouring pixels to generate a prediction block, corresponding to the current block; and a decoding unit for decoding the current block using the prediction block.

EFFECT: technical result is higher decoding efficiency of the area in which gradation exists.
