Abstract

The invention discloses an image noise reduction method and a storage medium, and the method comprises the following steps: S1, judging whether an input image contains noise pixel points or not, and further judging the type of each noise pixel point if the input image contains the noise pixel points; s2, sequentially processing the noise pixel points by adopting a corresponding noise reduction method according to the types of the noise pixel points; and S3, outputting the image after noise reduction processing. Since different types of noise pixel points in the input image are respectively processed by adopting corresponding noise reduction methods, detail information of the image can be reserved as much as possible, the blurring degree of the processed image is greatly reduced, the quality of the image after noise reduction is improved, and the method is relatively low in algorithm complexity and relatively high in applicability.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image noise reduction method and a storage medium. Background technique [0002] With the development of integrated circuit manufacturing technology and the continuous improvement of integrated circuit design level, CMOS image sensors manufactured based on CMOS integrated circuit technology have high integration, low power consumption, small size, simple process, low cost and short development cycle. And other characteristics, so that it is gradually in an advantageous position in the competition of CCD. CMOS image sensors are widely used in various photographic products and have broad market application prospects. However, after the image information in the image sensor is processed by an analog circuit, the image quality will be degraded due to the interference of the imaging device and external environmental noise. In particular, vertical stripes and various bright or dark...
