Abstract

The invention discloses an image processing method and an electronic device to solve the problem of the prior art that high operational pressure is caused to hardware by image registration during noise reduction by means of fusion of multiple frames of images. The method is applied to the electronic device. The electronic device comprises an image acquisition unit and a motion sensing unit, wherein the motion sensing unit is used for detecting the motion parameters of the image acquisition unit. The method comprises the steps of acquiring the ith motion parameter through the motion sensing unit when the image acquisition unit acquires N frames of continuous images, wherein the ith motion parameter is obtained when the image acquisition unit acquires the ith frame of image in the N frames of images, N is an integer larger than or equal to 2, and i is a positive integer smaller than or equal to N; conducting registration on the N frames of images at least according to the first motion parameter to the Nth motion parameter; processing the N frames of images obtained after registration according to the noise reduction algorithm to enable a noise reduction image to be generated.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image processing method and an electronic device. Background technique [0002] With the rapid development of digital image acquisition technology, not only digital cameras, digital video cameras and other image acquisition devices have become popular, but also devices such as smart phones, tablet computers, smart watches and other devices can also have good image acquisition functions. However, due to the limited size of the photosensitive element in the device, the photosensitive area of ​​a single pixel is relatively small, and the number of photons that can be received per unit time is limited, resulting in insufficient exposure of photos in low-light environments and poor imaging effects. [0003] At present, there are two ways to solve this problem: first, prolong the exposure time, so that the photosensitive element can get enough light input, which can produce an output...
