Image coding method and device based on multiple CMOS sensors

Abstract

The invention provides an image coding method and device based on multiple CMOS sensors. The method comprises the following steps: acquiring pixel voltages of N CMOS sensors to the same object; determining the voltage of each pixel of the object collected by one CMOS sensor in the N CMOS sensors as the reference voltage of each pixel of the object; detecting the reference voltage of each pixel of the object, and finding out the reference voltage with defects; correcting the reference voltage with defects based on the pixel voltages of the object collected by the remaining N-1 CMOS sensors to obtain a corrected reference voltage; and encoding the reference voltage of the object and the corrected reference voltage into a digital image using a digital signal processor. A voltage collected by an optimal sensor in a plurality of CMOS sensors is used as a reference voltage, voltages collected by other sensors are used for correcting a defective voltage in the reference voltage, and then a digital image is obtained through coding, so that the quality of the image is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image coding method and device based on multiple CMOS sensors. Background technique [0002] In CMOS sensors, due to the integration of multiple functional transistors in the pixel structure, CMOS image sensors also have some shortcomings, mainly because noise affects image quality. In the prior art, the improvement of the image quality is mainly to solve the defect of the generated image by using an image processing algorithm after the image is generated. [0003] The post-processing algorithm of the image, because the pixel value is generated, generally RGB, etc., the processing efficiency is low when processing, and the processed image is unnatural, or the generated image will show traces of image modification (that is, manual modification) , which many people do not want to see. [0004] In the prior art, there is also a technology for synthesizing or repairing ...
