    摘要： Provided are a signal readout circuit and a method therefor. In the signal readout circuit, a readout row selector is configured to gate a row of pixel units in a pixel array. A reset row selector is configured to gate first reset switches of the row of pixel units. Each pixel unit in the row in a pixel subarray included in the pixel array converts an optical signal into an electrical signal, and outputs the electrical signal to a connected pixel subarray readout feedback circuit. When it is determined based on the electrical signal that a signal generation condition is met, a reset signal is generated and sent to a first pixel unit, and an output signal is generated for output.

    摘要： An image sensor includes a first pixel group, a second pixel group arranged in at least one of the same column and row as the first pixel group, a first analog-to-digital converter and a second analog-to-digital converter, each of the first and second analog-to-digital converters being configured to process pixel signals output from the first pixel group and the second pixel group, and a switching circuit configured to selectively transmit a first pixel signal output from the first pixel group to the first analog-to-digital converter or the second analog-to-digital converter and to selectively transmit a second pixel signal output from the second pixel group to the first analog-to-digital converter or the second analog-to-digital converter. While the first analog-to-digital converter is connected to the first pixel group to process the first pixel signal, the second analog-to-digital converter is connected to the second pixel group to process the second pixel signal. Accordingly, AF information may be more effectively obtained.
