Embodiment 1

[0061] Embodiment one: refer to figure 1 and Figure 8 As shown, the lens 1 is a reverse image lens (or a positive image lens), including a lens body 5, a focusing mirror 7 is housed in the lens body 5, and an image axis angle adjustment mirror 8 is housed in some lens bodies 5, and the rear end of the lens body 5 is connected to the photoelectric lens. An image beam cavity 9 is provided between the sensors 3, and a grating with adjustable width is provided at the rear end of the beam cavity 9 for the purpose of adjusting the exposure. Multiple lenses 1 and mechanical adjustment mechanisms are installed in the same frame to form a lens group. The lens group is a fixed-focus lens group with a flat belt, and the frame of the lens group is provided with a quarter-arc cut surface, an arc-shaped plane centered on the rotation axis of the lens group, and a fixed circular-arc groove-shaped foundation The track 10 has a gear plate 18 above the base track 10, which is engaged with the...

Embodiment 2

[0063] Embodiment two: refer to Figure 6 and Figure 8As shown, a plurality of lens 1 is a positive image lens, and the lens group is an arc band fixed-focus lens group or a flat band fixed-focus lens group (the upper and lower sides of the image band are arc-shaped in the vertical direction, which is called an arc-shaped surface image band, referred to as an arc belt; the top and bottom of the image belt are flat in the vertical direction, called a plane image belt, referred to as a flat belt), and the photoelectric sensor 3 is a belt-shaped spherical arc surface structure (both vertical and horizontal directions are arc-shaped surfaces) or a belt-shaped barrel arc-shaped surface structure (the vertical direction is a plane, and the horizontal direction is an arc-shaped surface), in which the arc-belt fixed-focus lens group must be used with the band-shaped spherical arc-surface photoelectric sensor 3, and the flat-band fixed-focus lens group must be used with the band-shape...

Embodiment 3

[0064] Embodiment three: refer to Figure 2-5 and Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that the lens group is a zoom lens group, and a zoom lens 6 is housed in the lens body 5, and the outside of the lens group frame is provided with a cut surface that is a quarter arc shape, and a plane for the rotation of the lens group An arc with the axis as the center, a fixed circular arc groove-shaped basic track 10, a multi-directional gear 11 above the basic track 10 and a step-variable proportional gear plate 12 coaxial with the multi-directional gear. The shaft of the gear plate 12 is fixedly connected with the lens group, and the multi-directional gear 11 is meshed with a rail gear 13 whose shaft can move. The "stepless" change between the points close to the starting point of the viewing angle, the adjustable side bar 16 of the photoelectric sensor is engaged with the step-variable proportional gear plate 12 for transmission. Therefore, the tran...

Abstract

The invention discloses a multilens scanning type digital imaging method. A plurality of lenses participate to form an image together; the image formed by each lens only occupies one part of the whole image, for example, all the lenses are distributed in the vertical direction, the image surfaces formed by the lenses are tightly distributed in the vertical direction to form an image band in the vertical direction; visual angle start points of all the lenses are arranged on the same point, and the lenses do arc motion in the horizontal direction by adopting the point as a center and scan a scene; the image band can be pushed in the horizontal direction to form a larger image; and a photoelectric sensor behind the lenses receives the image step by step in various ways, and a digital image is formed after digital processing. The invention has feasible principle, novel design, easy construction and high imaging quality, fully improves the imaging resolution and displays advantages relative to the traditional imaging method along with the improvement of the resolution of the photoelectric sensor, thereby obtaining popularization and application in a large range.

Description

technical field [0001] The invention belongs to the technical field of digital imaging, and in particular relates to a multi-lens scanning digital imaging method. Background technique [0002] The resolution of a photographic photo is the most important performance indicator of a camera. Current digital cameras are mainly based on single-lens imaging. Due to the limitation of application fields (portable cameras, SLR cameras, medium-format cameras, and large-format cameras), the specifications of camera lenses are limited within a certain range, and within this range, the resolution of a single lens is close to the limit. A slight increase in the resolution of an existing lens necessitates a disproportionately large increase in its production cost. But at the same time, the resolution of the photoelectric sensing method is far from reaching the limit, and its improvement and development are geometrically improved. In the near future, it will definitely exceed the resolutio...
