Patent attributes
An image processing apparatus in an image processing system configured to generate a virtual point image using a plurality of images captured by a plurality of image capturing apparatus receives a first difference image being based on a difference between a third image based on image capturing performed by a third image capturing apparatus of the plurality of image capturing apparatuses and a second image based on image capturing performed by a second image capturing apparatus of the plurality of image capturing apparatuses and has a smaller data amount than that of the third image, and acquires a foreground image by extracting a predetermined object from the second image, using the received first difference image and a second difference image between a first image based on image capturing performed by a first image capturing apparatus of the plurality of image capturing apparatus and the second image.
