Abstract

The invention discloses a method for noise suppression by using multiple digital pictures, which is used for denoising by virtue of multiple digital pictures, wherein the digital pictures are firstly subject to a feature weighting processing program and the picture feature compensation of target pixels, and then noise suppression is carried out on the target pixels by carrying out interactive reference on multiple continuous or similar digital pictures. The method for noise suppression by using multiple digital pictures, which is provided by the invention, comprises the following steps: acquiring multiple digital pictures; carrying out a first pixel compensation program on each digital picture; and carrying out a second pixel compensation program on a comparison picture in the digital pictures. In the noise suppression method disclosed by the invention, pixels of which the picture features are similar and the degree of similarity is high are used to repair, thus not destroying the digital pictures, so as to obtain better picture quality.

Description

technical field

[0001] The invention relates to a digital image processing method, in particular to a method for suppressing noise by using multiple digital images. Background technique

[0002] With the rapid development of digital cameras, the demand for digital images has also increased significantly. Digital cameras use flat photosensitive elements to capture an entire image, or to capture a square area from it. Once the exposure operation is completed, the control circuit will transfer the charge on the capacitor unit to the next adjacent unit, and when it reaches the last unit on the edge, the charge signal is transmitted to the amplifier and converted into a potential. This goes on and on until the entire image is converted into a potential, sampled and digitized and stored in memory.

[0003] However, after a long time exposure of the photosensitive component, the surface charge of the photosensitive component will be disturbed. Due to the relationship of charge d...
