Abstract

The invention discloses an image processing method and device. The method includes: sequentially setting AD gain parameters, AD bias parameters and constant current source DC parameters; adjusting constant current source GS parameters to obtain bright data and dark data; obtaining image data, and according to the preset correction formula, the bright data and the The dark data is used to process the image; and the corrected image data is output. The present invention achieves the purpose of eliminating the background data by increasing the value of the dark data in the correction formula. The dark data is obtained by increasing the exposure time in an appropriate short time; the CIS image sensor collects image data through this scheme, and after correction, it can reach The background data is completely eliminated, and the image data consistency is better.

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...
