  • Publication number: 20210250556
    Abstract: An image generation device includes a first color signal generation unit that generates three or more types of first color signals Rl, Gl, and Bl by combining two or more types of near-infrared light signals SIR1 and SIR2 with three or more types of visible light signals SR, SG, and SB in arbitrary proportions. The visible light signals SR, SG, and SB are outputted from a solid-state imaging element, and the near-infrared light signals SIR1 and SIR2 are acquired simultaneously with the visible light signals SR, SG, and SB. The near-infrared light signals SIR1 and SIR2 are a signal based on near-infrared light and a signal based on near-infrared light. The first color signal generation unit 1 changes combining proportions of the visible light signals SR, SG, and SB and the near-infrared light signals SIR1 and SIR2 according to quality and/or strengths of each light signal.

  • Patent number: 9955098
    Abstract: To improve the speed of AD conversion. An amplifier amplifies, by a magnification larger than 1, signals of a pixel that outputs a signal in which there is no accumulation of a charge by a photon as a reset signal, and outputs a signal in which there is accumulation of a charge by a photon as an accumulation signal. A calculation unit generates an offset amount signal corresponding to an amount of own offset component using the amplified signal, and calculates a digital value corresponding to the own offset component using the generated offset amount signal and accuracy set for AD conversion of the amplified accumulated signal.

    Abstract: Provided are an image pickup device and a camera system that are capable of detecting an extremely small signal from a pixel or one photon signal with low noise and high precision at high speed, and are capable of performing various kinds of high-performance shooting by increasing a frame rate with use of this. Each sense circuit includes a comparator configured to compare an output signal from a pixel with a reference signal, and when signal detection is performed, a charge allowing a first pixel signal output from a selected pixel to be cancelled out is held in one or both of input sections of the comparator, an independent offset bias for each comparator is applied to one of the input sections of the comparator to cancel out an offset of the comparator, and a digital decision on intensity of light incident on the pixel is performed by comparing a reference signal changing in steps with a second pixel signal output from the selected pixel.
