Abstract:
An information processing apparatus using a distance measuring apparatus, said information processing apparatus comprising:first and second area sensors; a distance calculation circuit which divides said first area sensor comprising a plurality of pixels into a plurality of pixel blocks, divides said second area sensor comprising a plurality of pixels into a plurality of pixel blocks, and calculates distance for each of pixel blocks in said first and second area sensors; and a shape determination circuit which selects pixels blocks, as a specific area, which are calculated as representing a shorter distance than the distance represented by the other pixel blocks, extracts a contrast changing point in the specific area on the basis of brightness information of each of pixels in the specific area, confines a boundary portion of an image in the specific area from the extracted contrast changing point information, and specifies a shape of the image.
