  • CMOS image sensor pixel array and readout method with LED flicker mitigation
    Patent number: 12022222
    Abstract: A CMOS image sensor with an imaging array of pixels containing selected pixels wherein illumination from a normal image is received by one set of pixels and illumination from an LED light source is received by another. The readout method serially separates the normal image signal from the LED light sourced signal. The signal from the selected pixels is resilient against saturation and thereby contributes to increased HDR. The image sensor array and readout method may be incorporated within a digital camera.
