  • Solid-state image-capturing apparatus, camera, and method of processing signal
    Patent number: 8102445
    Abstract: A solid-state image-capturing apparatus that converts light, which is reflected from a subject, into an electrical signal, includes an image processing unit that performs edge enhancement on a digital video signal that is generated based on an analog video signal, which is obtained from the light captured by an image-capturing device and amplified with a predetermined analog gain, based on position information on the image-capturing device and the analog gain.
    Type: Grant
    Filed: June 29, 2009
    Date of Patent: January 24, 2012
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Shiroshi Kanemitsu, Takaaki Kawakami, Junichi Hosokawa, Yuuki Koguchi
  • Solid-state device having digital signal processing circuit
    Patent number: 8077253
    Abstract: An analog signal photo-electrically converted in a pixel of a light receiving area is converted to a digital signal by an ADC. The digital signal is processed by a digital signal processing circuit, and then, successively output as a digital video signal. The digital signal processing circuit has a first signal processing block for detecting and correcting a pixel defect and preventing a noise, and a second signal processing block for restoring apparent resolution lost by the processing by the first signal processing block.
