Zusammenfassung:PROBLEM TO BE SOLVED: To detect a search window with high accuracy.SOLUTION: An image processor 100 acquires image data of a television program or the like, and generates edge image data 122 by extracting an edge from the image data. The image processor 100 extracts horizontal straight lines from the edge image data 122. The image processor 100 extracts a black pixel connection area obtained by connecting edges in the edge image data 122, and determines, as a search window, a combination of straight lines having the black pixel connection area within a predetermined range between combinations of the plurality of straight lines.
