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...

Embodiment Construction

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] The present application provides a focus implementation method, device, and electronic equipment. After the user selects a target object in the current preview image presented on the display screen of the electronic equipment, the electronic equipment will obtain the first focus position. At this time, the first focus position A focus position can indicate the position of the target object in the current preview image. Therefore, based on the first focus...
