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

[0072] Such as figure 2 —8, 10-13, an image acquisition method based on a two-stage integrated lens and a single offset sensor body, the image acquisition system with a two-stage integrated lens and a single offset sensor body includes a body 1 and lens, there is a circular opening on the front panel of the fuselage as a lens interface;

[0073] (1) The integrated lens is docked on the circular opening; an image sensor 13 is arranged in the fuselage;

[0074] The image sensor is arranged offset from the axis of the circular opening, and the plane where the image sensor is located is perpendicular to the axis;

[0075] (2) The lens is an integrated lens 2 with a two-stage structure, and four sub-lenses 4 with different focal lengths are integrated in the lens barrel of the integrated lens; each sub-lens contains a group of lenses;

[0076] The optical axes of the four sub-lenses are all parallel to the axis of the integrated lens; and the four sub-lenses are arranged in the ...

Embodiment 2

[0097] The rest are the same as in Embodiment 1, the difference is that 3 sub-lenses are integrated in the integrated lens, see Figure 9 .

Embodiment 3

[0099] The rest are the same as in Embodiment 1, the difference is that 6 sub-lenses are integrated in the integrated lens, see Figure 10 .

[0100] 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; frame or APS-H frame, APS-C frame, 1 / 1.63 inch frame or 1 / 1.7 inch frame.

[0101] 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)

[0102] The socket can be used to connect the lens to the processor of the fuselage,...

Abstract

The invention discloses an image obtaining method based on a lens with two integrated segments and a camera body with a single offset sensor, wherein digital images are obtained by an image obtaining system. The image obtaining system comprises the camera body (1) and the lens (2), wherein the image sensor (13) is arranged in the camera body and deviated from the axis of a circular opening; the integrated lens (2) of a two-segment structure is composed of the front segment (22) and the rear segment (21); the rear segment is clamped or fixed with the circular opening of the camera body; the front segment can coaxially rotate relative to the rear segment to switch sub lenses; and the camera body is equipped with a display screen. The image obtaining method based on the lens with the two integrated segments and the camera body with the single offset sensor is easy to implement, and ingenious in conception; and can combine the excellent optical performance of multiple prime lenses with the portability of the structure consisting of one camera body and one lens.

Description

technical field [0001] The invention relates to an image acquisition method based on a two-stage integrated lens and a single-offset sensor body. 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 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. One battery can only take dozens of photos or more than a hundred photos. Although it is generally very light, the battery life The ability cannot meet the requirements of the majority of users. [0004] For cameras with interchangeable lenses, mainly SLRs and mirrorless cameras (such as S...
