Description

A kind of miniature camera that can rotate automatically and camera method

technical field

The invention relates to the technical field of cameras, in particular to a miniature camera capable of automatic rotation and a camera method.

Background technique

In recent years, miniature cameras have been widely used in handheld smart terminals such as mobile phones, and have more and more functions. For example, many manufacturers have released smartphones with wide-angle shooting functions, which add a good experience to users in scenes such as shooting landscapes and group photos. However, due to the limitation of the optical structure of the wide-angle camera itself, the current miniature camera is still insufficient when it needs to take pictures with a large angle.

In order to solve this problem, manufacturers generally use a software synthesis scheme to make up for it. That is, the user manually rotates the mobile phone, takes three photos of left, middle and right, and then combines them into one photo through the background of the mobile phone software. The shortcomings of this method are obvious, because the manual unavoidable picture dislocation problem of the two photos before and after can only be compensated by algorithmic stitching and photo cropping. The result is that the stitching position will have a certain distortion, and the cropping will also lose some shooting information.

It can be seen that if a self-rotating miniature camera can be developed, the above problems can be solved.
