Abstract

The invention discloses a variable aperture module, a periscopic camera and electronic equipment. The variable aperture module comprises a shading blade and a lead screw nut transmission mechanism, wherein the shading blade is connected with the lead screw nut transmission mechanism, and the lead screw nut transmission mechanism is used for controlling the shading blade to do reciprocating rectilinear motion. When the size of the aperture needs to be adjusted, the shading blade is controlled through the lead screw nut transmission mechanism, so that the shading blade is driven to shield the periscopic camera, the incident illumination intensity and the field depth of the periscopic camera are changed, the shooting effect is enhanced, and meanwhile, the application range is widened.

Description

technical field [0001] The present invention generally relates to the field of electronic technology, and in particular to a variable aperture module, a periscope camera and electronic equipment. Background technique [0002] The aperture size of the mobile phone camera is an important factor affecting the photo effect. The large aperture camera has a large aperture size, which allows more light to enter the camera module and shortens the shutter time. It is suitable for shooting moving objects and has a shallow depth of field. It is suitable for scenes such as blurring the background and highlighting the subject; while the small aperture camera has a longer shutter time, which is suitable for shooting car tracks and star tracks, etc., and the depth of field is deep, ensuring the clarity of objects in multiple depths of field. [0003] Compared with the zoom capability of traditional cameras, periscope cameras have powerful optical zoom capabilities, such as a maximum of 10 ...
