Problems solved by technology

[0004] When shooting, if the distance between the lens of the camera equipment and the object to be photographed is less than the minimum focus distance, the lens cannot focus accurately and the captured picture is not clear. If it is greater than the minimum focus distance, the close-range photography of the lens cannot be fully utilized function, unable to maximize the use of the minimum focus capability
Since the user cannot know the minimum focusing distance, the user keeps moving back and forth to adjust the distance between the camera device and the object to be photographed, which increases power consumption, increases the shooting cost, and reduces the shooting efficiency

Abstract

The invention discloses a method and a device for prompting focusing during shooting. The method for prompting focusing during shooting comprises the following steps: acquiring a measured distance through a distance sensor, wherein the measured distance is a distance between the imaging surface of shooting equipment and a shot object; displaying focusing prompt information according to the measured distance and the minimum focusing distance of the shooting equipment. According to the method and the device for prompting focusing during shooting disclosed by the invention, a user can be prompted to keep a distance a lens and the shot object within a reasonable range during close shot, so that the close shot efficiency is increased.

Description

technical field [0001] The invention relates to the field of digital photography, in particular to a method and device for prompting focus during shooting. Background technique [0002] At present, more and more mobile terminals are equipped with digital camera lenses for digital camera, and become camera equipment. Users can take pictures and videos with different contents by using the digital camera lenses on these camera devices, which enhances users' interest in using the camera devices. [0003] When a digital camera lens is used for close-range shooting, the distance between the digital camera lens and the object to be photographed is limited by the minimum focus distance, which is the distance between the imaging plane of the camera device and the object to be successfully focused by the camera device. The minimum value of the distance between photographed objects is usually determined by the hardware optical elements of the camera equipment. [0004] When shooting,...
