EXPLOITING FRAME TO FRAME COHERENCY IN ARCHITECTURE OF IMAGE CONSTRUCTION WITH PRIMITIVES SORTING AT INTERMEDIATE STAGE Russian patent published in 2018 - IPC G06T11/40 

FIELD: image processing means.

SUBSTANCE: group of inventions relates to image processing technologies. Method for displaying an image is proposed. Method comprises the step of accumulating a compact representation of the geometry, input data and state for the image tile when creating a list of image primitives for the tile. In this case, before rasterizing the tiles, it is determined whether the compact representation for the tile in the current picture frame with a compact representation for the corresponding tile in the preceding image frame coincides by checking, whether there is one primitive from the list of primitives completely overlapping the tile, and whether the specified primitive closes all other primitives in the list of primitives.

EFFECT: technical result is the reduction of computing power in image processing by identifying cases where it is possible to use the tile from the previous frame and no tile processing is required from the current frame.
