Patent number: 6959113Abstract: An arbitrary-shape image-processing device comprises a CCD by which a two-dimensional image is obtained. The image may be rectangular, and a contour of an image area contained in the image may be a circle. Pixel values contained in the image area are converted to a one-dimensional data array, and are recorded in a recording medium. Further, the numbers of pixels of the vertical and the lateral lengths of the two-dimensional image, the coordinates of the center of the circle of the image area, and the radius of the circle are recorded in the recording medium as shape information. Thus, all of the image data of the two-dimensional image is not recorded in the recording medium, but only the image data contained in the image area and the shape information are recorded.Type: GrantFiled: September 12, 2001Date of Patent: October 25, 2005Assignee: PENTAX CorporationInventors: Nobuaki Abe, Tetsuya Abe
