IMAGE PROCESSING DEVICE AND METHOD Russian patent published in 2015 - IPC H04N19/52 G06T1/00 G06T9/00 

FIELD: physics, photography.

SUBSTANCE: invention relates to an image processing device and method, which can improve encoding efficiency, thereby preventing increase in load. The technical result is achieved due to that a selection scheme 71 from a prediction scheme 64 by filtering selects a motion compensation image for generating a prediction image at a high-resolution extension level from key frames at a low-resolution base level. The filter scheme 72 of the prediction scheme 64 by filtering performs filtration, which includes high-frequency conversion and which uses analysis in the time direction of a plurality of motion compensation images at the base level, selected by the selection scheme 71, in order to generate a prediction image at the extension level.

EFFECT: reducing load in terms of the amount of processing owing to spatial increase in sampling frequency at the base level for encoding the current frame.
