Video camera automatic focusing system and video camera automatic focusing method

Abstract

The invention discloses a video camera automatic focusing system and a video camera automatic focusing method, which relate to the technical field of video cameras. The method provided by the invention comprises the following steps: a microprocessor receives a current scene picture photographed by a video camera, a focusing position of several target objects and a background in the picture is obtained through a picture focus estimation module, the microprocessor processes the information to obtain relative focusing position values, the values are transmitted to a focusing control module, the focusing control module controls a focusing motor, the video camera photographs one picture while moving every position, after all the input focus positions used in photographing, all the pictures aretransmitted to an image fusion processing module, and finally, a high-resolution image is obtained, and the image is previewed on a display screen of the video camera or stored in a memory chip. The method provided by the invention can solve the defects, such as inaccuracy of the existing manual focusing, slow speed and low efficiency of the other automatic focusing, and failure in immediately obtaining an ideal high-resolution image of the existing video camera.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a camera automatic focusing system and method. Background technique [0002] The focusing of the camera was initially carried out manually, but now it is gradually replaced by an automatic focusing system or module, and with the development of the detector, the automatic focusing technology is constantly improving. Now more and more video cameras, digital video cameras, etc. have adopted automatic focusing technology. As a result, most of the automatic focusing problems are also highlighted. The focusing accuracy is not enough, and the focusing position cannot be found accurately; After the focus is adjusted, some targets are not clear, which requires post-processing by technicians to obtain a high-resolution image and other shortcomings. These problems directly affect the customer experience. [0003] Existing pan-focus imaging systems generally include three parts: a high-sp...
