Problems solved by technology

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 the environment, the process of changing lenses becomes more and more difficult

Embodiment 1

[0062] Such as Figure 2-13 , an image acquisition method based on a new bayonet and an integrated lens, using an image acquisition system with a new bayonet and an integrated lens, the image acquisition system includes a fuselage (1) and a lens, and the front panel of the fuselage A body mount (5) for docking with the lens is provided;

[0063] (1) The lens is an integrated lens, and the integrated lens is docked on the bayonet (5) of the fuselage; an image sensor (13) is arranged in the fuselage;

[0064] The image sensor is set offset from the axis of the bayonet (5) of the body [the offset can be offset in any direction, such as 0°, 45°, 90°, 180° relative to the center of the bayonet ° (eg image 3 shown)], the plane where the image sensor is located is perpendicular to the axis;

[0065] (2) N sub-lenses (4) with different focal lengths are integrated in the lens barrel of the integrated lens; 3≤N≤12, N is a natural number; each sub-lens contains a group of lenses;

...

Embodiment 2

[0083] The rest are the same as in Embodiment 1, the difference is that 3 sub-lenses are integrated in the integrated lens, see Figure 14 .

Embodiment 3

[0085] The rest are the same as in Embodiment 1, the difference is that 6 sub-lenses are integrated in the integrated lens, see Figure 15 .

[0086] The rest needs to be explained: there is a focus motor on the body or the integrated lens, and an optical image stabilization system is installed on the body or the integrated lens; the image sensor is a CMOS sensor, and the image sensor is a single-layer or three-layer sensor; The top of the body is equipped with a flash and a shutter button (3), an auto / manual focus module is integrated in the body, the image sensor is square, and a touch-sensitive layer is provided on the display screen; format or APS-H format, APS-C format, 1 / 1.63 inch format or 1 / 1.7 inch format.

[0087] The image sensor can be a CCD sensor, a CMOS sensor, a single-layer mosaic sensor, or a three-layer sensor (refer to the FOVEON X3 full-color image sensor chip used by sigma)

[0088] The image sensor is a CCD sensor or a CMOS sensor; the image sensor is ...

Abstract

The invention discloses a novel bayonet and integrated lens-based image obtaining method. An image obtaining system with a novel bayonet and an integrated lens is adopted and the system comprises a machine body (1) and the lens; a front panel of the machine body is provided with a machine body bayonet (5) for being jointed with the lens; the lens is the integrated lens which is jointed on the machine body bayonet (5); an image sensor is arranged by being deviated from the axis of the machine body bayonet (5); N sub lenses (4) with different focal lengths are integrated in a lens cylinder of the integrated lens. The bayonet based on a fore shaft rotary ring and a telescopic check sheet structure is adopted. The novel bayonet and integrated lens-based image obtaining method can be used for conveniently obtaining images, and the excellent optical performance of multiple prime lenses and the portability of one machine (the machine body) and one lens (the lens) are both considered.

Description

technical field [0001] The invention relates to an image acquisition method based on a novel bayonet and an integrated lens. Background technique [0002] Existing mainstream camera systems are generally divided into interchangeable lens cameras and non-interchangeable lens cameras. [0003] 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, 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. [0004] For cameras with interchangeable lenses, mainly SLRs and mirrorless cameras (such as Sony’s nex serie...
