Abstract

An embodiment of the invention discloses a noise reduction method. The method comprises the following steps of acquiring a color value of a first sub-pixel point in an image to be processed and acquiring a first color value; determining a sub-pixel point possessing a same color channel with the first sub-pixel point in the image to be processed within a preset range taking the first sub-pixel point as a center and acquiring a second sub-pixel point; acquiring a color value of the second sub-pixel point and acquiring a second color value; and based on the first color value and the second colorvalue, adjusting the color value of the first sub-pixel point. The embodiment of the invention also discloses noise reduction equipment and a computer readable storage medium. Noise reduction processing is performed on a Bayer format image so that a noise influencing image quality is fundamentally eliminated and output image quality is guaranteed.

Description

Technical field [0001] The present invention relates to noise reduction technology in the field of image processing, in particular to a noise reduction method, equipment and computer-readable storage medium. Background technique [0002] In the existing photographing technology, the most primitive image obtained after the camera is used to shoot the subject is the Bayer format image; usually the terminal needs to perform a certain data format conversion on the most primitive Bayer format image obtained, that is, from the Bayer format The image is converted to a YUV format image, and then the resulting image is output. Among them, the YUV format is also called the optimized color video signal (YCrCb) format. [0003] However, in the existing image format conversion technology, when the Bayer format image is converted to the YUV format image, the noise in the Bayer format image that affects the image quality is amplified, resulting in poor image quality of the obtained YUV format. ...
