Abstract

The invention discloses a focusing device and a method, relates to the technical field of computers, is applied to the technical field of camera module detection, and particularly relates to a focuse method for inverse imaging. According to the embodiment of the invention, light carrying pixel structure information can be transmitted to a detection lens by utilizing an optical sensor device; transmitting the light to an image sensor device through a detection lens, and generating image data by using the image sensor device so as to send the image data to a terminal in real time; the terminal receives the image data in real time and calculates a contrast score corresponding to the image data; performing fitting on discrete data formed by the contrast score, and calculating a target focal length of the to-be-focused lens; therefore, the problems that manual focusing is low in automation degree, poor in focusing precision and high in complexity of adjusting the set focal length are solved, and meanwhile the problem that focusing time is long in automatic focusing is solved. The focusing accuracy is improved; and the focusing efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a focusing device and method. Background technique [0002] At present, common methods for adjusting the focus of the lens include: manual focusing and automatic focusing. Manual focusing has the problems of low degree of automation, poor focusing accuracy due to manual operation, and high complexity of adjusting the set focal length (for example: finite distance and infinite distance); while automatic focusing equipment is usually a lighted camera After the module is assembled, the specific test standard sample is shot, and the lens module to be focused is automatically adjusted by judging its resolution, usually by adjusting the automatic exposure to check whether the image meets the test requirements. The automatic focusing device has a focus loss The time is longer, which reduces the efficiency of focusing. Contents of the invention [0003] In view of this, the embodim...
