At the fourth position, the fourth image of the object to be photographed is acquired and stored in the stored first image, the second image A storage unit for two-image and four-scattered images. Afterwards, the first image, the second image, the third image and the fourth image are synthesized and modified by the image processing unit in the mobile terminal 200 to obtain a full-color image.

According to a second aspect of the embodiments of the present disclosure, a mobile terminal is provided, as shown in FIG. 5 , including the camera device 100 according to the embodiment of the first aspect.

The mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a camera, a wearable device such as a watch, a smart bracelet, or the like.

In the mobile terminal 200 of the embodiment of the present disclosure, based on the driving element driving the camera module 20 to rotate as a whole, the image sensor 23 can move a distance less than the distance between two adjacent pixels, thereby sensing a position that cannot be reached by a conventional image sensor A high-resolution image is obtained by processing multiple images. Since the support portion is supported on the side of the camera module 20, the camera module 20 is supported by the floating support portion, and does not occupy the space of the camera module 20 in the optical axis direction, so that the height of the entire camera device 100 can be reduced, Therefore, the occupation of the thickness space of the mobile terminal 200 can be reduced, which is beneficial to the ultra-thinning of the mobile terminal 200 .
