Abstract

The invention relates to a method and device for improving the definition of a static photographing picture of a camera and electronic equipment. The method comprises: recording multiple frames of images formed in the focusing search process; dividing each frame in the multiple frames of images into a first block and at least one second block; counting the definition of the first block and the definition of each second block of each frame in the multi-frame image; selecting a frame with the highest definition of the first block as a base frame; in the second blocks at the same position in different frames, selecting the frame with the highest definition as a fusion frame of the second block at the position; and fusing the basic frame and the at least one fusion frame to form an image. According to the present invention, based on the existing hardware capability, through the fusion of the base frame and the fusion frame, the definition level of static image shooting is improved.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, a device and an electronic device for improving the clarity of a still photographed picture of a camera. Background technique [0002] Currently, in order to ensure the clarity of the picture, the center-weight focusing method and the average-weight focusing method are mainly used. [0003] The center-weighted focusing method is based on the principle that the center confirms that the center of the picture has the best sharpness. The center-weighted focusing method can only ensure the best performance of the sharpness of the center of the picture, and the sharpness performance of the corners of the picture cannot be guaranteed. Moreover, it is caused by the non-parallel imaging planes of the module's transparent lens (Lens) and the module's photosensitive chip (sensor) Partial blur cannot be remedied. [0004] The structure of the camera module is as figure 1 ...
