Method, device and electronic equipment for realizing focusing

Abstract

The invention provides a focusing realizing method, a focusing realizing device and electronic equipment. The focusing realizing method, the focusing realizing device and the electronic equipment are used on the condition that light strength of a target photographing object is relatively low and the electronic equipment cannot realize focusing by means of an existing automatic focusing mode or only low focusing accuracy is realized. A user selects the target photographing object in a current previewing image so that the electronic equipment acquires a first focusing position which can indicate the position of the target photographing object in the current previewing image. Afterwards the electronic device can directly make a light beam which is emitted from a controllable light source be projected on the target photographing image based on the first focusing position, thereby improving light strength of the target photographing object so that image contrast of the target photographing object is maximized. Furthermore normal operation of shielded pixels is ensured, and furthermore the electronic equipment accurately and quickly performs focusing on the target photographing object, thereby improving user experience.

Description

technical field [0001] The present invention mainly relates to the technical field of image acquisition, and more specifically relates to a focusing realization method, device and electronic equipment. Background technique [0002] In practical applications, in order to obtain images with various shooting effects, it is usually necessary to adjust the focal length of the electronic device, that is, the focusing process. At present, most electronic devices such as mobile phones and SLR cameras use automatic The circuit drives the motor to move the lens to the corresponding position, so that the object to be photographed is automatically and clearly imaged. [0003] Among them, the commonly used autofocus methods include TTL (through the taking lens) and PDAF (phase detection auto focus, phase detection autofocus), etc. The former adjusts the contrast of the image at the focal point by moving the lens, and finds the lens position with the highest contrast, which is accurate F...

Problems solved by technology

[0006] In view of this, the present invention provides a focusing realization method, device and electronic equipment, which solves the problem that in the existing focusing process, due to insufficient light intensity on the object to be photographed, it approaches the background color and affects the shaded pixels. The normal work, resulting in inaccurate focus or even unable to focus, thus affecting the technical problems of user experience
