摘要： A photoelectric conversion apparatus includes a pixel, an A/D conversion portion and an output circuit. The pixel includes first and second photoelectric conversion portions and an accumulation portion configured to accumulate a signal charge in a location other than the photoelectric conversion portions. The A/D conversion portion is configured to perform A/D conversions on signals based on signal charges generated in the photoelectric conversions. The output circuit reads out first and second signals based on first and second signal charges accumulated in the first and second photoelectric conversion portions during an electric charge accumulation period and a third signal based on a third signal charge generated in the second photoelectric conversion portion and accumulated in the accumulation portion during the electric charge accumulation period. Conversion periods for analog-to-digital conversion to be performed on at least two of the first, second, or third signals have different lengths.

摘要： The invention is relates to systems and methods for high dynamic range (HDR) image capture and video processing in mobile devices. Aspects of the invention include a mobile device, such as a smartphone or digital mobile camera, including at least two image sensors fixed in a co-planar arrangement to a substrate and an optical splitting system configured to reflect at least about 90% of incident light received through an aperture of the mobile device onto the co-planar image sensors, to thereby capture a HDR image. In some embodiments, greater than about 95% of the incident light received through the aperture of the device is reflected onto the image sensors.

摘要： First and second readout circuits, each having a respective floating diffusion node, are coupled to a photodetection element within a pixel of an integrated-circuit image sensor. Following an exposure interval in which photocharge is accumulated within the photodetection element, a first portion of the accumulated photocharge is transferred from the photodetection element to the first floating diffusion node to enable generation of a first output signal within the first readout circuit, and a second portion of the accumulated photocharge is transferred from the photodetection element to the second floating diffusion node to enable generation of a second output signal within the second readout circuit. A digital pixel value is generated based on the first and second output signals.
