Patent number: 7476837Abstract: An amplification type solid-state image pickup device of the invention includes a plurality of photoelectric conversion sections 10 each having an embedded photodiode 1 and a transfer transistor 2, a switched capacitor amplifier section 20 whose input side is connected to a charge detection node 8 to which output terminals of the plurality of photoelectric conversion sections 10 are connected in common, and a current amplification section 21 connected between the switched capacitor amplifier section 20 and a vertical signal line 9. Signal charge from the plurality of photoelectric conversion sections 10 is converted into voltage by the switched capacitor amplifier section 20, and the converted signal is current-amplified by the current amplification section 21 and outputted to the vertical signal line 9. Thus, a less-noise, high-quality image can be obtained while a reduction of the pixel size is achieved by reducing the number of transistors per pixel.Type: GrantFiled: January 31, 2008Date of Patent: January 13, 2009Assignee: Sharp Kabushiki KaishaInventor: Eiji Koyama

Patent number: 7477442Abstract: A large number of holes are formed in a two-layered porous film sandwiched between a lower substrate and an upper substrate and filled with a light transmitting liquid and fine particles. When a voltage is applied between an upper electrode and a lower electrode, migration of the fine particles, takes place based on electrophoresis. White color is displayed when the fine particles are located on an upper transparent porous film side and black color is displayed when the fine particles are located on a lower black porous film side. Color display is also possible by periodically repeating three primary colors of RGB in the lower layer porous film or arranging a color filter on the transparent upper substrate. Bubbles-containing fine particles or bubbles themselves may be employed in place of the fine particles.Type: GrantFiled: January 21, 2004Date of Patent: January 13, 2009Assignee: Sharp Kabushiki KaishaInventors: Tadashi Iwamatsu, Hiroyuki Hirakawa, Nobuyuki Azuma, Yoshinori Mutou

Patent number: 7475997Abstract: A reflective display includes a retroreflective layer and a modulation layer, which is provided closer to a viewer than the retroreflective layer is and which is switchable between first and second states with mutually different optical characteristics. The retroreflective layer includes a two-dimensional arrangement of unit elements, which are arranged at a pitch of at most 250 ?m. The retroreflective layer has a retro-reflectivity Rr of at least 45%. The retroreflectivity is defined as a ratio of the intensity of light, which has been reflected from the retroreflective layer and then received at a cone angle of 7.5 degrees by a retroreflectivity measuring system, to that of light, which has been reflected from a dielectric mirror and then received by the same retroreflectivity measuring system.Type: GrantFiled: October 15, 2004Date of Patent: January 13, 2009Assignee: Sharp Kabushiki KaishaInventors: Sayuri Fujiwara, Kiyoshi Minoura

Publication number: 20090009592Abstract: Information for each of a right eye and a left eye obtained by a pair of cameras, which is provided on a three-dimensional image information obtaining apparatus, is displayed on a three-dimensional image display apparatus. An optical axis of each of the cameras is disposed so as to intersect each other on a horizontal surface or on a surface inclined with respect to the horizontal surface. Based on a detection result of a distance sensor for detecting a distance between each of the cameras and a subject, an image capturing position of each of the cameras is adjusted such that the intersection point of the optical axes of the cameras is on the subject. The image information for the right eye and the left eye obtained by the three-dimensional image information obtaining apparatus is printed on a recording sheet by a three-dimensional image printer. Hence, it is possible to positively obtain a three-dimensional image in line with a stereoscopic image recognized by a user's eyes.Type: ApplicationFiled: September 30, 2005Publication date: January 8, 2009Applicant: SHARP KABUSHIKI KAISHAInventors: Yoshiki Takata, Takashi Morimoto

Publication number: 20090009673Abstract: It is possible to decrease block segmentation and flickering due to separate exposure in an active matrix substrate while avoiding decreased aperture ratio, increased parasitic capacity and complication in manufacturing process. A first pixel circuit and a second pixel circuit including a first-type TFT and a second-type TFT, respectively, are disposed alternately relative to each other in both directions of row and column in an active matrix substrate. In the first-type and the second-type TFTs, a pattern misalignment of the drain electrode with respect to the gate electrode in an up-down direction will increase/decrease a gate-drain parasitic capacity Cgd in reverse ways. By disposing these two types of TFTs in uniform dispersion, the increase/decrease in the parasitic capacity Cgd caused by pattern misalignment occurring at the time of manufacture are averaged.Type: ApplicationFiled: March 6, 2006Publication date: January 8, 2009Applicant: SHARP KABUSHIKI KAISHAInventor: Yuhko Hisada
