  • Patent number: 11172157
    Abstract: Techniques are described for digital conversion of pixel signals in a CMOS image sensor (CIS). The CIS includes column-parallel analog-to-digital converters (ADCs), each having a programmable gain amplifier (PGA) supporting N gain settings. Each ADC can execute, for each gain setting (Gn) of the N gain settings, a respective reset phase conversion to obtain a respective baseline offset (BOn) associated with the Gn. A pre-decision value can be determined as a function of a pixel signal, the pre-decision value corresponding to a selected one of the gain settings (Gs). The pixel signal can be converted by using the pre-decision value to set a gain of the PGA to the Gs and obtaining a signal offset (SO). A digital pixel output can be computed for the pixel signal as a function of the SO and the BOs, wherein the BOs is the BOn corresponding to the Gs.

  • Patent number: 11172143
    Abstract: This invention enables one to check flicker of a HFR image signal. A display image signal of a first frame rate for flicker check is obtained on the basis of an image signal of a second frame rate. For example, the display image signal of the first frame rate is generated from the image signal of the second frame rate by a frame thinning process. In this case, a frame to be thinned is determined from a relationship between the second frame rate and a light source frequency. For example, the number of frames to be a flicker period is obtained from the second frame rate and the light source frequency, and the frame to be thinned is determined so that continuous frames of the number of frames to be the flicker period are present.

  • Patent number: 11146748
    Abstract: An imaging device includes pixel units, a control unit, and a correction unit. The control unit causes each pixel unit to output first and second signal. The first signal is a potential of a floating diffusion held when the charge accumulated in a photoelectric conversion unit is transferred upon a transfer switch being closed. The second signal is a potential of the floating diffusion held when a reset switch is closed with the transfer switch being open. The correction unit generates, with respect to the first and second signals output by each pixel unit, the pixel signal by subtracting a correction amount from a signal intensity of the first signal. The correction amount is a product of a signal intensity of the second signal and a coefficient determined in advance in accordance with a position of each pixel unit.
