Classification: CPC G | IPC G

Claim 8:
9. A non-transitory computer readable storage medium storing a program for causing a computer to perform an image processing method comprising:
generating a reference image of a foreground by extracting a foreground area from a captured image by learning;
generating a comparison image for comparing with the reference image by extracting a foreground area from the captured image based on a difference between the captured image and a background image a threshold value that is selectively set from a plurality of threshold values having a possibility of being set in threshold value adjustment;
determining, based on the reference image and the comparison image, a threshold value that is used for generation of a foreground image based on a difference between the captured image and a background image corresponding to the captured image; and
generating a foreground image based on a difference between the captured image and the background image and the determined threshold value.
