  • Publication number: 20160182839
    Abstract: An image capturing apparatus is provided. The apparatus comprises an image sensor comprising pixels and a controller. The pixels include a photoelectric converter, a holding unit, an output unit and a first and second transfer unit. The controller causes the sensor to repeatedly perform a holding operation that the first transfer unit transfer charge from the photoelectric conversion unit to the holding unit, and a transfer operation that the second transfer unit transfer the charge from the holding unit to the output unit. The controller causes the sensor to perform, as the holding operation, holding operations including a first holding operation for performing the first transfer unit transfer charge generated in a first exposure time and a second holding operation for performing the first transfer unit transfer charge generated in a second exposure time longer than the first exposure time.

  • Publication number: 20160173796
    Abstract: A solid-state imaging apparatus includes: a pixel region configured to output an analog signal; an analog-to-digital conversion unit configured to convert the analog signal into a digital signal; and a transmitting unit configured to perform a transmission of a test signal and the digital signal obtained as a result of the conversion by the analog-to-digital conversion unit, the digital signal being transmitted subsequently to the test signal, and the analog-to-digital conversion unit converts the analog signal into the digital signal during a period of the transmission of the test signal by the transmitting unit.

  • Publication number: 20160112663
    Abstract: A solid-state imaging apparatus comprises a pixel unit including G-pixels 110-G, R-pixels 110-R, and B-pixels 110-B, an image signal output interval of the G-pixels 110 made shorter than image signal output intervals of the R-pixels and B-pixels. Regarding lights respectively having wavelength bands near a green color, near a red color, and near a blue color, the G-pixels 110-G have higher sensitivity to the wavelength band near the green color than both to the wavelength band near the red color and wavelength band near the blue color, the R-pixels 110-R have higher sensitivity to the wavelength band near the red color than both to the wavelength band near the green color and wavelength band near the blue color, and the B-pixels 110-B have higher sensitivity to the wavelength band near the blue color than both to the wavelength band near the green color and wavelength band near the red color.

  • Publication number: 20160044259
    Abstract: A solid-state imaging apparatus includes a first light-shielded pixel region including two or more rows of pixels each including a photoelectric converter which is shielded from light, an aperture pixel region including pixels each including a photoelectric converter which is not shielded from light, and a control unit configured to perform control such that a charge accumulation period for the pixels in the first light-shielded pixel region is longer than a charge accumulation period for the pixels in the aperture pixel region and time to read signals from the pixels in a first row of the first light-shielded pixel region is different from time to read signals from the pixels in a second row different from the first row of the first light-shielded pixel region.
