摘要： An image sensor having an image acquisition mode and an ambient light sensing mode includes a pixel array having pixel cells organized into rows and columns for capturing image data and ambient light data. Readout circuitry is coupled via column bit lines to the pixels cells to read out the image data along the column bit lines. An ambient light detection (“ALD”) unit is selectively coupled to the pixel array to readout the ambient light data and to generate an ambient light signal based on ambient light incident upon the pixel array. Control circuitry is coupled to the pixel array to control time sharing of the pixels cells between the readout circuitry during image acquisition and the ALD unit during ambient light sensing.

摘要： A hybrid ADC having a successive approximation register (SAR) ADC mode for generating a bit of a digital signal and a ramp ADC mode for generating an additional bit of the digital signal is disclosed. When in the SAR ADC mode, a control circuit is configured to disable a ramp signal generator; disable a counter; and enable a register to control an offset stage to set the magnitude of an offset voltage that is provided to an input of a comparator of the ADC. When in the ramp ADC mode, the control circuit is configured to enable the ramp signal generator to provide a ramp signal to the input of the comparator; enable the counter to begin providing the digital count in response to the output of the comparator; and disable the register so that the offset stage is not providing the offset voltage.
