Abstract

The invention relates to a light prompting device and an image acquisition device. The light prompting device comprises a light source and a light guide device, wherein the light source is used for generating prompt lights; and the light guide device is arranged on an outer lens and is used for changing the light paths of the prompting lights generated by the light source, accordingly, the prompting lights only propagate beyond a framing scope of the lens, and the propagation scope of the prompting lights and the framing scope of the lens complement each other. The light prompting device provided by the embodiment of the invention utilizes the complementarity of the lighting scope of the prompting lights which are generated by the light prompting device and the framing scope, so that both a photographer and a photographed person can accurately know the framing scope through the prompting lights, the photographed person can conveniently and actively adjust the position, and the photographer can frame and photograph more conveniently and accurately.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to an optical prompting device and an image acquisition device for prompting the scope of shooting and framing. Background technique [0002] At present, when an image acquisition device captures an image or a dynamic image, it usually finds a view through a viewfinder. Viewfinders include optical viewfinders and electronic viewfinders. But no matter what kind of viewfinder it is, the photographer needs to observe the shooting range displayed in the viewfinder with his eyes to determine that the subject being photographed is within the shooting range. And the subject has no way of knowing whether he is in the shooting range. When there is no photographer, such as self-portrait, video conference, etc., the subject cannot accurately know whether he is on camera, and it is difficult to judge the scene of the shooting. In addition, sometimes it is inconvenient for the photo...
