Patent number: 7457486Abstract: A solid-state imaging element includes photoelectric conversion elements having a complementary or Bayer color filter array. The solid-state imaging element adds together electric charges stored in nine photoelectric conversion elements having color filters of one of multiple colors in each portion of six rows and six columns, to obtain a resulting electric charge, and outputs the resulting electric charge as one pixel. A portion for one of the colors deviates from a portion for each of the other colors by three rows and/or three columns. This pixel-addition operation produces an effect of a spatial low pass filter, thereby reducing signal components exceeding a Nyquist frequency corresponding to a target resolution. Consequently, aliasing noise in an image with the target resolution is reduced, and therefore higher image quality can be achieved, when compared with a conventional resolution reduction technique.Type: GrantFiled: September 30, 2004Date of Patent: November 25, 2008Assignee: Panasonic CorporationInventors: Makoto Kawakami, Kazuyuki Inokuma, Toshiya Fujii

Patent number: 7408683Abstract: An image sensor including a plurality of photoelectric conversion elements arranged in a main scanning direction, a plurality of switching elements connected to respective ones of the photoelectric conversion elements, individually, and a controller for generating a clock signal to control the switching elements. The photoelectric conversion elements are divided into plural groups, each including a predetermined number (N) of the photoelectric conversion elements. The outputs from the photoelectric conversion elements in one group are read out simultaneously in response to the clock signal generated from the controller, thereby attaining a high speed reading of a document.Type: GrantFiled: July 14, 2003Date of Patent: August 5, 2008Assignee: Brother Kogyo Kabushiki KaishaInventors: Tatsuya Sato, Tetsuya Kato

Patent number: 7399992Abstract: An integrated circuit chip (IC) is equipped with a device for preventing reverse engineering by monitoring light emissions emitted from transistors and such electrically active devices in a circuit located in the IC. The device emits extraneous randomized light emissions in substantial close proximity to the transistors to hide a pattern of light emissions emitted from the transistors. As one feature, the device can include a source of randomized light emissions in substantial close proximity to the transistors to hide a pattern of the emitted light from the transistors in randomized light emissions emitted by the source. As a second feature, the device can emit the randomized light emissions by randomly delaying an electrical signal that is electrically coupled to the transistors and, in response to the randomly delayed electrical signal, the transistors randomly emitting light emissions thereby hiding a separate pattern of light emission emitted from the transistors.Type: GrantFiled: October 2, 2006Date of Patent: July 15, 2008Assignee: International Business Machines CorporationInventors: Jeffrey A. Kash, James C. Tsang, Daniel R. Knebel

Patent number: RE40680Abstract: A multi-resolution color contact-type image sensing apparatus whereby a color image of an original can be obtained with a particular resolution, depending upon the size of the original image. A first array of photosensor segments with a base resolution is arranged with at least one other array of photosensor segments having a greater-than-base resolution. All such photosensor segments might be aligned in a single linear array, with at least one portion of segments having a greater-than-base resolution. A resulting image with at least the base resolution could be created depending upon the size of the original in relation to the placement and width of the greater-than-base resolution segments. A plurality of linear arrays might also be used, with each successive array having a greater resolution than the previous array. Moreover, the arrays might be arranged in parallel with each successive array being narrower in width than the previous.Type: GrantFiled: November 27, 2001Date of Patent: March 24, 2009Assignee: Hewlett-Packard Development Company, L.P.Inventor: Bradley Suggs
