Camera device for portable terminal

technical field

The invention relates to a camera device for a portable terminal, in particular to a periscope camera suitable for a portable terminal.

Background technique

In recent years, mobile terminals such as mobile phones have become more and more popular, and a photographing function has become an important function of the mobile terminal. The cameras of current mobile terminals usually only have an electronic zoom function, and a few cameras with optical zoom lenses need to be attached to the outside of the mobile phone, which are bulky and difficult to carry. This is contrary to the trend of ultra-thin mobile terminals.

As shown in Figure 1, the camera in a traditional mobile phone generally consists of a lens group 10 and a photoreceptor 20. The lens group 10 is made of several pieces of glass, fluorite or plastic or other transparent materials, and the photoreceptor 20 is made of a photosensitive semiconductor. The device is manufactured, and the lens group 10 and the photoreceptor 20 are arranged along the thickness direction of the mobile phone. The incident light enters from the lens group 10, and the image is projected onto the photoreceptor 20 by the lens, and the semiconductor photoreceptor 20 converts the light image into a photo represented by an electrical signal.

Since the lens surface of the traditional mobile phone camera is located on the front or back of the mobile phone, the lens and photoreceptor of the camera are compressed in a narrow space smaller than the thickness of the mobile phone. Therefore, the number of lenses in the lens group is very small, and there is no space for optical zooming. Therefore, when performing optical zooming, the lenses need to move back and forth along the optical axis.

FIG. 1 schematically shows the structural arrangement of a camera device of a conventional mobile terminal. As shown in FIG. 1 , the lens group 10 and the photoreceptor 20 are arranged along the thickness direction of the mobile phone. Since the thickness of the mobile terminal is getting thinner and thinner, there is no room for the lens group to perform optical zooming by telescopic movement in the direction of the optical axis.

This application first made the first step of improvement, that is, let the lens group 10 in Figure 1 be arranged along the long side (or short side) of the mobile phone, but in this case, in order to make the lens group face the front when shooting subject, the end face of the mobile terminal (for example, the head end face 4) needs to face the front subject, so that the screen of the mobile phone is facing up, rather than parallel to the subject, the user cannot see the shooting details in time and is not conducive to adjusting the shooting Angle, will bring great inconvenience to the user. For this reason, the application has been further improved, specifically as follows.
