Patent number: 7218348Abstract: An object is to prevent a false signal from being generated. In a CCD comprising a lot of photodiodes, vertical transfer paths, and a horizontal transfer path, signal charges respectively representing R, G and B color components are mixed in the horizontal transfer path.

Patent number: 7190403Abstract: A solid-state image pickup apparatus includes a timing signal generator for generating timing signals. Particular gates formed in each of photosensitive cells arranged in an image pickup section are driven independently or simultaneously in response to the timing signals. In an independent drive mode, outputs each having particular sensitivity are obtained from the different photosensitive regions of the individual cell by one time of exposure, covering a range of sensitivity as broad as one achievable with repeated photometry. This reduces the number of times of photometry for determining adequate exposure. In a simultaneous drive mode, outputs are produced in the usual manner. An exposure value calculator converts the resulting image signals to values having a predetermined format while an exposure parameter determining section determines exposure parameters if those values are adequate.Type: GrantFiled: July 18, 2003Date of Patent: March 13, 2007Assignee: Fuji Photo Film Co., Ltd.Inventors: Hitoshi Yamashita, Naoki Kubo, Keizou Uchioke

Patent number: 7148925Abstract: A solid-state image pickup apparatus includes a color filter including complementary color filter segments. When a shutter release bottom is pressed to its half-stroke or full-stroke position, light incident via the filter is picked up in a movie/photometry or a still picture mode, respectively. While signal charges are read out of an image sensor in accordance with the mode, the signal charges are digitized to become pixel data. In the movie/the photometry mode, despite that a plurality of pixel data are mixed together, a set of primary color pixel data are generated as if pixel signals were thinned out by mixture. In the still picture mode, all the pixels are sequentially read out and interpolated to generate primary color pixel data greater in number than photosensitive cells. The primary color data are raised in frequency to enhance the resolution of a picture.Type: GrantFiled: March 14, 2001Date of Patent: December 12, 2006Assignee: Fuji Photo Film Co., Ltd.Inventors: Masaru Osada, Koji Ichikawa, Masafumi Inuiya

Patent number: 6882364Abstract: A solid-state imaging apparatus includes an image pick-up section in which photosensitive devices are arranged in, e.g., a honeycomb G square lattice, RB full-checker pattern due to shifted pixels. Regions void of the photosensitive devices are assumed to be virtual photosensitive devices.

Interpolation can be executed with the high quality signals to the limit of resolution with an adequate circuit scale.Type: GrantFiled: December 2, 1998Date of Patent: April 19, 2005Assignee: Fuji Photo Film Co., LTDInventors: Masafumi Inuiya, Masaru Osada, Takeshi Misawa, Kenkichi Hayashi, Satoru Okamoto, Osamu Saito

Patent number: 6654056Abstract: Geometric configurations for photosites found on photosensitive chips for creating electrical signals from an original image, as would be found, for example, in a digital scanner, copier, facsimile machine, or other document generating or reproducing device. The photosensitive chips are mounted on a substrate to form a photosensitive array in a full width scanner or other photosensitive device. The geometric configurations reduce the Moiré patterns to provide a higher quality image.Type: GrantFiled: December 15, 1998Date of Patent: November 25, 2003Assignee: Xerox CorporationInventors: Alain E. Perregaux, Jagdish C. Tandon, Paul A. Hosier, Roger L. Triplett, Xiao-Fan Feng

Publication number: 20030193588Abstract: A wirelessly remote control battery powered self-video capturing capability camera mounting device system especially for handheld video camera. It provides the user the ability to control the video capturing direction of the handheld video camera from a distance away. The video camera mounting stage provides polar rotational movement both horizontally and vertically. The rotational movement is controlled by remote device as the input instructional device by the user. The signal is then transmitted to the video camera mounting stage via wireless signal transmission. The camera mounting stage receives the signals and generates functions to drive the designated motors to move the camera video capturing direction to the decided direction. The user can then confirm the results from the LCD screen of the video camera and fine tune the direction of the video camera mounting stage. This device provides the user the opportunity to be in the video while taking video pictures for the occasion.Type: ApplicationFiled: March 28, 2002Publication date: October 16, 2003Inventors: Siltex Peter Yuen, Silbert Yuen
