Abstract

The invention discloses a pixel processing circuit, method and device and electronic equipment, belongs to the technical field of communication, and can solve the problem that the image quality of an image shot by the electronic equipment is poor. The pixel processing circuit comprises a control logic module, a first RST reset gate and a first circuit module, wherein one end of the control logic module is connected with one end of the first RST reset gate, and the other end of the first RST reset gate is connected with the first circuit module; the control logic module is used for controlling the first RST reset gate to be in a first working state under the condition that a first control signal is received, the first RST reset gate is used for adjusting the exposure of at least one pixel in a pixel matrix corresponding to a shooting object in the first working state, and the first circuit module is used for processing light corresponding to the shooting object. The embodiment of the invention is applied to the process of processing at least one pixel in the pixel matrix.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a pixel processing circuit, method, device and electronic equipment. Background technique [0002] Generally, in order to improve the image quality of the image captured by the electronic device, it can be achieved by increasing the signal-to-noise ratio of the image. Specifically, after the external light (that is, the light corresponding to the object to be photographed) passes through the lens of the electronic device, when filtered by an infrared filter, the light transmittance of the light can be increased to increase the light transmitted to the sensor (sensor). The signal intensity value of the light on the photosensitive diode (pixel), so as to achieve the purpose of improving the signal-to-noise ratio of the image; and the photosensitive diode can convert the perceived light signal into an electrical signal, through the amplification circuit a...
