Description

An Image Acquisition Method Based on New Bayonet and Integrated Lens

technical field

The invention relates to an image acquisition method based on a novel bayonet and an integrated lens.

Background technique

Existing mainstream camera systems are generally divided into interchangeable lens cameras and non-interchangeable lens cameras.

Non-interchangeable lens cameras are mainly card cameras, which use a body and a lens, and the body and lens are completely connected together, and cannot be disassembled when the user uses it. The biggest problem with this mode is that 1) if it is an automatic Zoom lens, the zoom of the lens needs to be driven by the body, the battery consumes fast, and the battery life is poor. Generally, a battery can only take dozens of photos or more than a hundred photos. Although it is generally very light, the battery life is limited. Can not meet the requirements of the majority of users.

For cameras with interchangeable lenses, they are mainly SLRs and mirrorless cameras (such as Sony’s nex series of mirrorless cameras, Nikon’s J series, and Canon’s EOS M series); see Figure 1, these cameras have an image sensor in the body , due to the use of interchangeable lens mounts, excellent imaging is achieved through the support of the lens group. But the shortcomings of this kind of camera are also obvious, because only one lens can be connected at a time. For professional photographers, it is necessary to equip multiple fixed-focus heads. When traveling or performing special shooting tasks, it is necessary to carry multiple lenses out at the same time. It is large, and the process of switching lenses is relatively cumbersome: first remove the lens, then replace it with another lens, put on the back cover of the lens, and during the process of changing the lens, it is easy to cause dust intrusion inside the fuselage, and if the camera is exposed to harsh conditions Working in an environment, the process of changing lenses becomes more and more difficult.

Therefore, it is necessary to design a new mode of photography and video recording methods.
