IMAGE PROCESSING DEVICE AND METHOD OF DRIVING IMAGE PROCESSING DEVICE Russian patent published in 2013 - IPC G06T3/40 H04N5/262 H04N1/387 

FIELD: physics.

SUBSTANCE: image processing device for applying film grain effects on an image of received image data includes a generating unit configured to generate, based on pixel values randomly read from grain data including a plurality of pixel values, a basic grain image having a certain size larger than the grain data; a resizing unit configured to resize the basic grain image generated by the generating unit to have the same size as the received image data; and a combining unit configured to combine the basic grain image resized by the resizing unit with the received image data.

EFFECT: image processing where, having a small amount of film grain data, the same film grain is obtained for multiple images having different sizes while preventing formation of periodic structures.
