ABSTRACT:
As image data have come to be used in large volumes in recent years, statistical calculation processing of restored and sampled image data often suffers a shortage of memory capacity. In acquiring a feature amount of an image to automatically correct image data, where high-speed processing is preferred, it is judged whether the image data contain thumbnail data (step108) and, when there are thumbnail data, “thumbnail” is set on a sampling flag (step110) to secure a buffer for developing the thumbnail data (step116and step120), the thumbnail data are developed in the buffer, and all the pixels are subjected to statistical calculation (step126through step132), resulting in faster processing than where the original image data are developed and sampled.
