IMAGE PROCESSING APPARATUS DETECTING QUADRILATERAL REGION FROM PICKED-UP IMAGE |
摘要 |
An image processing apparatus includes an obtaining section, a detection section, a first identification section and a second identification section. The obtaining section obtains image data of a first picked-up image and a second picked-up image picked up by an image pickup section. The detection section detects a brightness change region where brightness changes at predetermined time intervals in the first picked-up image on the basis of the obtained image data of the first picked-up image. The first identification section performs straight line detection processing on the obtained image data of the second picked-up image to detect a straight line, so as to identify a candidate straight line in a corresponding region corresponding to the brightness change region. The second identification section identifies a quadrilateral region including the candidate straight line as an extraction candidate region in the second picked-up image.
