Document Type and Number:
WIPO Patent Application WO/2012/011211
Kind Code:
A1
Abstract:
The present invention provides storage processing in which thumbnail image generation processing generates a thumbnail image by minimizing an image to be reduced and stores image data of the image in image memory, whereupon the image data contains pixel information which indicates the color of a pixel for each of the pixels contained in the image; DMA control processing which specifies the readout address of the image memory such that reading out of the image data from the image memory is performed so as to decimate a portion of the pixel information for each group of a plurality of a predetermined number of units of pixel information; and thumbnail image output processing for outputting thumbnail images which are based on the image data which has been read out from the image memory.
