ABSTRACT:
A method for suppression of image blur is applied to an image capturing apparatus in a photography mode whose exposure time is set to be greater than a safe exposure time. The method comprising the following steps: capturing a long exposure image with the present exposure time, and a short exposure image with an exposure time smaller than or equal to the safe exposure time in the same landscape. Besides, obtain a locus signal in the process of long exposure image capture. Afterwards, execute an arithmetic procedure to smooth the short exposure image, and then produce a point scale image using the auxiliary arithmetic of locus signal. Finally, process the long exposure image and the point scale image with multiplication arithmetic to restore the long exposure image, thus forming an output image.
