DEVICE FOR CREATING IMAGE FILES, IMAGE PROCESSING DEVICE, METHOD OF CREATING IMAGE FILES, IMAGE PROCESSING METHOD AND IMAGE FILE DATA STRUCTURE Russian patent published in 2014 - IPC G06T15/00 G06F12/08 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to the technology of processing images in order to zoom in or zoom out an image displayed on a display or move the image up, down, right or left. The technical result is achieved using hierarchical data in which image data, representing an image with different resolution levels, are organised according to resolution levels, contain three types of data consisting of a heading 150, index blocks 160 and tile images 170; the heading 150 defines multiple regions formed by decomposing a hierarchical structure in virtual space, in which hierarchical data are generated; an indicator is defined in each region, said indicator indicating at least one of the index blocks; the index blocks 160 are generated for each region in the structure defined by the heading 150; the indicator, which indicates one of the tile images 170, is defined for positions in images of many layers belonging to each region; the images 170 are image data actually used for rendering the image.

EFFECT: high efficiency of displaying an image owing to an algorithm which separately stores and efficiently reproduces texture data.
