Pixel circuit and pixel control method

Abstract

Provided are a pixel circuit and a pixel control method capable of quickly controlling pixels with a simpler configuration of a combination of a photosensor and an image sensor. The pixel circuit includes a photosensor, and a dual gate transistor having a first gate connected to a first terminal of the photosensor, and a second gate connected to a pixel unit drive circuit, and a bias electrode connected to a second terminal of the photosensor. The dual gate transistor operates as a switch of the pixel unit drive circuit and an amplifier of the photosensor. A pulse level of the second gate is adaptively controlled.
