Classification: CPC G | IPC G

Claim 0:
1. An image processing apparatus comprising:
one or more memories storing instructions; and
one or more processors executing the instructions to:
generate a reference image of a foreground by extracting a foreground area from a captured image by learning;
generate 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 and a threshold value that is selectively set from a plurality of threshold values having a possibility of being set in threshold value adjustment;
determine, 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 the background image corresponding to the captured image; and
generate a foreground image based on a difference between the captured image and the background image and the determined threshold value.
