Abstract

The invention discloses an image jitter compensation method and device and a storage medium, and belongs to the technical field of image processing. The method comprises the steps of detecting whetherthe jitter amount of the mobile terminal is greater than a preset threshold at a shutter response moment; if the jitter amount is greater than the preset threshold, further detecting the maximum jitter direction of the mobile terminal at the shutter response moment; selecting a corresponding interval output mode for the pixel array of the image sensor according to the maximum jitter direction ofthe mobile terminal so as to obtain a front frame of original image and a rear frame of original image at the shutter response moment; and performing image synthesis on the front and back frames of original images to generate a final target image. According to the technical scheme provided by the invention, the image smearing phenomenon caused by jittering during shooting can be effectively solvedwhen the mobile terminal jitters during shooting without adding extra hardware.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image shake compensation method, device and storage medium. Background technique [0002] As the camera function of the mobile terminal is more and more concerned and favored by consumers, the quality of the camera function has become an important indicator to measure the performance of the mobile terminal. To measure the quality of its camera function mainly depends on the clarity of the image it shoots. The quality of an image is good or bad, and the clarity is very important. Image clarity mainly depends on the performance of the module body and the optimization of post-image processing. Of course, it is first necessary to ensure that the photographer can take stable photos. However, in real life, not all photographers\users can take stable images (images without shaking), and in many scenes such as dark scenes, sports (buses, etc.), and capturing children...
