Description

A mobile phone realizing optical zoom

technical field

The invention relates to a mobile phone, in particular to a mobile phone for realizing optical zoom.

Background technique

Optical zoom refers to the method that the camera relies on the optical lens to achieve zooming. Optical zoom changes the focal length of the lens by changing the relative position of each lens in the zoom lens in the camera, thereby changing the viewing angle.

In the prior art, mobile phones mainly acquire and process images through a camera module, wherein the camera module includes multiple lenses, infrared filters, image sensors, digital signal processors, and soft boards. Among them, the lens is an important component for obtaining images. Since the distance between multiple lenses needs to be adjusted during the zooming process, it is necessary to leave enough space for the lens to move. Due to the small thickness of the body of the mobile phone, and the camera in the mobile phone is arranged perpendicular to the front panel of the mobile phone, this traditional setting limits the variable focus space of the camera module and cannot achieve optical zoom, so that the existing mobile phones can only use The way of digital zoom is also the reason why optical zoom can only be realized in professional cameras. Although the digital zoom can also achieve the function of zooming, the digital zoom does not change the focal length of the lens, but only changes the angle of the imaging plane to achieve the change of the viewing angle. Due to the limited amount of data of the digital zoom, the zoomed-in picture is actually effective. The number of pixels has not increased, resulting in poor image quality.

Therefore, it is necessary to propose a mobile phone that realizes optical zoom, so as to overcome the defects in the prior art.
