Abstract

The invention discloses an image processing method and an image processing device. The image processing method comprises steps that an AD gain parameter, an AD bias parameter, a constant current source DC parameter, and a constant current source GS parameter are sequentially set, and the AD bias parameter is set to be positive bias; light data and dark data are acquired; image data is acquired, and the image data is processed according to the light data, the dark data, and a preset correction formula; the corrected image data is output. By aiming at a condition of a cis image sensor of weak original image consistency, exposure adjusting time length and light data, dark data acquisition time length are consistent during actual application, and the exposure time length is freely adjusted according to a concrete algorithm. The AD bias is the positive bias, and the size of the dark data is improved, and the size of the light data is fixed according to the exposure time length, and then the wi-di value of the correction formula is relatively reduced, and a y value is used to reduced an image difference by adopting a correction formula principle.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image processing method and device. Background technique [0002] The application of the CIS image sensor requires the AD chip to complete sampling and analog-to-digital conversion, and the constant current source chip to complete the driving and lighting of the light source. The AD chip has two registers, gain and bias, and the bias can be set to positive bias and negative bias. The constant current source chip has DC parameters and GS parameters. The DC parameters provide the current to drive the light source, and the GS parameters provide the exposure time of the light source in the form of PWM waves. The image collected by CIS must be corrected to meet the image consistency requirements of the application. [0003] When processing the corrected image in the algorithm part, it is often necessary to eliminate the background data. At pre...
