Image processing apparatus and method and program
First Claim
1. An image processing apparatus comprising:
- difference region detection means for detecting a difference region in which a first image and a second image supplied from image pickup means for picking up an image have a difference; and
determination means for determining the similarity between an image of the difference region and an image in a peripheral region around the difference region and determining based on the similarity whether the difference region is a region in which a body appears or a region in which a body disappears.

Abstract
An image processing apparatus and method is disclosed by which a body can be detected using two picked-up images. An image storage section stores a current image supplied from an image pickup apparatus. A reference image storage section has stored therein a preceding image at a preceding timing. A difference calculation section produces a difference image between the current image supplied from the image storage section and the preceding image supplied from the reference image storage section. A labeling section performs labeling for the difference image to produce a difference region. A determination section determines, from regions of the current and preceding images corresponding to the difference region and surrounding regions of the current and preceding images around the regions corresponding to the difference region, whether the difference region is a region in which a body appears or a region in which a body disappears. The image processing apparatus can be applied to detection of a body from within an image.
