Abstract

The present application provides an image processing method and an image processing apparatus. In the image processing method and the image processing apparatus, according to coordinate values of feature point pairs between two short exposures acquired before and after the image to be processed, so as to eliminate the influence of translating the motion coordinates of pixel points in the image tobe processed by the photographing module in the process of photographing the image to be processed, thereby improving the accuracy of the blur kernel obtained according to the motion coordinates and improving the deblurring effect of the image to be processed.

Description

technical field [0001] The present application relates to the field of image processing, and more particularly, to an image processing method and an image processing device. Background technique [0002] During the shooting process of the shooting device, due to shaking of the user's hands or other reasons, the imaging system shakes during the exposure process. If the exposure process is long or the degree of vibration of the imaging system is large, the image obtained by the imaging system will be blurred. [0003] Attitude sensor modules such as gyroscopes and accelerometers on the shooting equipment can record motion information during exposure to a certain extent. Combined with the internal parameters of the imaging system and the ideal focal length obtained during the autofocus process, the blurred image can be deblurred to obtain an image with improved clarity. [0004] The mathematical model of the blurred image can be regarded as the degradation of the clear image ...
