IMAGE PROCESSING DEVICE AND 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 includes a filtering processing unit configured to process bilinear interpolation if the value, calculated based on the neighbouring pixels of the current block during prediction processing within a frame when encoding the image data, is less than the threshold value set in accordance with the bit depth of image data for neighbouring pixels, to generate filtered neighbouring pixels; an intra prediction unit configured to perform prediction processing within the frame of the current block using filtered neighbouring pixels to generate the predicted block, corresponding to the current block; and an encoding unit configured to encode the current block using the predicted block.

EFFECT: technical result is reduced deterioration in image quality.
