Patent number: 11477402Abstract: To improve the correction accuracy in a solid-state image sensor that performs dark current correction. A solid-state image sensor includes a bias voltage supply unit and a signal processing unit. The bias voltage supply unit supplies a bias voltage of a predetermined value to a light-shielded pixel impervious to light in a period in which a light-shielded pixel signal is output from the light-shielded pixel, and supplies a bias voltage of a value different from the predetermined value to a photosensitive pixel not impervious to light in a period in which a photosensitive pixel signal is output from the photosensitive pixel. The signal processing unit executes processing of removing dark current noise from the photosensitive pixel signal using the light-shielded pixel signal.Type: GrantFiled: February 6, 2019Date of Patent: October 18, 2022Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventors: Minoru Urushihara, Tomohiro Sekiguchi

Publication number: 20100053428Abstract: The present invention relates to an image processing apparatus and an image processing method, a program, and an image display apparatus that are configured, when a predetermined image signal is superposed on an image signal before interpolation, to enhance the quality of an image signal after interpolation. A MPU 31 accepts a command for starting or ending superposition of a predetermined image signal onto an input image signal. If the command for starting or ending superposition is accepted, a interpolation processing block 72 detects a motion vector of an input image signal with superposition of a predetermined image signal started or ended and interpolates and outputs an interpolation signal on the basis of the motion vector regardless of a total reliability of the motion vector. The present invention is applicable to television receivers, for example.Type: ApplicationFiled: March 19, 2008Publication date: March 4, 2010Inventors: Takayuki Ohe, Masato Usuki, Minoru Urushihara, Kenkichi Kobayashi, Koji Moriya

Publication number: 20090208137Abstract: The present invention provides an image processing apparatus that generates interpolation image signals based on a motion vector between continuously input time-series image signals and increases time resolution. The image processing apparatus includes a feature variation detecting unit that detects a predetermined feature variation between the time-series image signals; a generation time setting unit that sets a generation time of the interpolation image signals; and an interpolation image signal generating unit that generates the interpolation image signals at the generation time set by the generation time setting unit.Type: ApplicationFiled: February 17, 2009Publication date: August 20, 2009Inventors: Minoru Urushihara, Hiroshi Takeuchi, Masato Usuki, Kenkichi Kobayashi

Patent number: 5835162Abstract: Upon NTSC broadcasting, switches are respectively electrically connected to the N sides and a three-dimensional comb filter is made up of memories, a subtracter, etc., whereby a carrier chrominance signal is separated from a video signal in accordance with a frame-to-frame process. In this case, the video signal is divided into two signals, which are in turn written into the memories. Upon EDTV2 broadcasting, the switches are respectively electrically connected to the E sides and a three-dimensional comb filter is made up of the memory and the subtracter, whereby a composite signal obtained by combining a carrier chrominance signal and a horizontal resolution supplementary signal is separated from the video signal. The switch is electrically connected to the E side and a three-dimensional comb filter is made up of the memory, a subtracter, etc., whereby a horizontal resolution supplementary signal is separated from a composite signal in accordance with a field-to-field process.Type: GrantFiled: July 19, 1996Date of Patent: November 10, 1998Assignee: Sony CorporationInventors: Satoshi Inoue, Minoru Urushihara
