[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0033] In order to restore common defocused blurred images, the present invention pre-loads a designed specific pattern aperture in the camera or video camera lens, retains more high-frequency information in image shooting, and then designs an evolutionary algorithm to calculate the position of the blurred image defocus blur kernels, and deconvolving them with the computed defocus blur kernels can lead to sharper images.
[0034] Based on above-mentioned principle, concrete implementation of the present invention is as follows:
[0035] Step 1: Insert the pre-designed special style gobo into the camera lens. Most of these special style gobos have a symmetrical shape and are mainly used to produce a symmetrical defocus blur kernel, such as Fig...
