Title: CMOS IMAGE SENSOR, PIXEL CIRCUIT AND DRIVE METHOD THEREOF
Abstract:
A CMOS image sensor, and a pixel circuit and drive method thereof. The CMOS image sensor pixel circuit comprises: a collection circuit, used to collect incident light and convert a collected optical signal into an electrical signal; a source tracking circuit, used to output a received electrical signal to a collected signal output terminal under the control of a scan line; a voltage conversion circuit, configured to be connected to the collected signal output terminal by means of a read signal line, converting voltage of the collected signal output terminal to an output voltage, and outputting same via a voltage output terminal; the output voltage is within an operating voltage range of an image processor.
