IMAGE PROCESSING SYSTEM, IMAGE PROCESSING METHOD, PROGRAM, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an image processing system that can realize image processing with minimized hardware resources in the case of directly connecting an image input device to a printer or a printer is integrally configured in an image input device. SOLUTION: A digital camera 1 calculates a reduction rate from an input image size and a print image size, determines the number of application times of low pass filtering on the basis of a result of the calculation of the reduction rate, uses a low pass filter of a basic configuration until the number of times for filtering application reaches the number of times to execute low pass filtering in vertical and horizontal directions and then transfers print data to a printer 3. In the case of the filter processing, the data after being subjected to low pass filtering are written back to areas of a memory in which the image data subjected to low pass filtering are deployed so that the memory areas which are required to deploy image data subjected to the low pass filtering is sufficient.
