Further, electronic equipment includes the module of making a video recording, because the flexible piece 300 of the module of making a video recording can realize the adjustment to the aperture size under the drive of camera lens subassembly 200, and then make the adjustment scope and the adjustment range of aperture bigger, the module of making a video recording can possess the function of main camera, portrait camera and super wide angle camera simultaneously, and then replace original a plurality of cameras through the big end camera of an iris, and then reduce the required space of module of making a video recording, reduced the occupation of the module of making a video recording to the space on the electronic equipment, be convenient for carry out miniaturization and frivolous design to electronic equipment.
Specifically, the angle of view=h×wd/f.
Where H is the imaging height, WD is the object distance, and f is the focal length.
When the photographed object is determined, the object distance and the focal length are fixed, the size of the photo is unchanged, and the imaging height is also fixed.
Because the size of the photo is unchanged, i.e. the imaging height is unchanged, if the angle of view is increased, the surrounding picture of the shot object is cut, so that the shot object is enlarged, the smaller angle of view is suitable for taking long-range scenes, and the larger angle of view is suitable for taking short-range scenes. The application realizes the adjustment of the angle of view by adjusting the diameter of the aperture, so that the camera module has the capability of shooting long-range scenes and also has the capability of shooting short-range scenes.
