Patent number: 7164786Abstract: Images sensed through object lenses 100R and 100L, having zoom lenses, with image sensors 102R and 102L are processed by image signal processors 104R and 104L, and an image of an object in each of the sensed images is separated from a background image on the basis of the processed image signals. The separated image signals representing the image of the object enter the image processor 220, where a three-dimensional shape of the object is extracted on the basis of parameters used upon sensing the images. The parameters are automatically adjusted so that images of the object fall within the both image sensing areas of the image sensors 102R and 102L and that they fall within the both focal depths of the image sensors 102R and 102L.Type: GrantFiled: May 5, 2003Date of Patent: January 16, 2007Assignee: Canon Kabushiki KaishaInventors: Tatsushi Katayama, Shigeki Okauchi, Nobuo Fukushima, Masakazu Matsugu, Katsumi Iijima, Masayoshi Sekine, Kotaro Yano, Sunao Kurahashi, Motohiro Ishikawa

Patent number: 7023479Abstract: Image data having a high S/N ratio is obtained even when the exposure time is relatively long. To achieve the above object, there is provided an image input apparatus in which an accumulation mode is set with the shutter open, thereby acquiring image data A1. The shutter is then closed, and the accumulation mode is set to acquire subtraction data between the image data and black image data A2. This processing is repeated to acquire image data A1 and subtraction data A2, and these subtraction data are added. These operations A1, A2, and A3 are repeated a predetermined number of times to update addition data, and image processing is performed on the basis of the updated addition data.Type: GrantFiled: May 14, 2001Date of Patent: April 4, 2006Assignee: Canon Kabushiki KaishaInventors: Makoto Hiramatsu, Motohiro Ishikawa
