Abstract

The utility model relates to a CMOS camera with a super-resolution reconstruction function. The CMOS camera comprises a fly-eye lens array for acquiring the target scene, wherein the fly-eye lens array comprises four square lens units which are distributed in a square symmetric manner; a COMS image sensor group at the rear side of the fly-eye lens array, wherein the COMS image sensor group comprises four COMS image sensors for receiving the target scene data acquired by the square lens units; and a processor unit in connection with the COMS image sensors. By the hardware method, the CMOS camera of the utility model solves the technical problem of low resolution under severe environments, and acquires data of the same target scene via the lens units of the fly-eye lens array and the corresponding COMS image sensors so as to achieve super resolution.

Description

The CMOS camera with super-resolution reconstruction function

Technical field

The utility model relates to a kind of CMOS camera, relates in particular to a kind of CMOS camera with super-resolution reconstruction function.

Background technology

Optical system played an important role in the information age, common optical system has camera, be widely used at present safety and monitoring field, yet, due to imaging technique restriction, camera is difficult to overcome the poor problem of resolution at present, while especially using at crossing, be often used for security monitoring, portrait is fuzzy, the image information of taking is difficult to the clue of investigating and collecting evidence as public security organ, so need a kind of camera that can realize super-resolution.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of CMOS camera with super-resolution reconstruction function, and this CMOS camera has solved under environment rugged environment by hardware means, the technical problem that resolution is low.

In order to solve the problems of the technologies described above, the utility model provides a kind of CMOS camera with super-resolution reconstruction function, comprise: for gathering the fly eye lens array of target scene, this fly eye lens array comprises: four square lens units, and described four square lens units are square symmetrical; Be positioned at the COMS imageing sensor group of described fly eye lens array rear side, this COMS imageing sensor group comprises: four for receiving respectively the COMS imageing sensor of the target contextual data of each square lens unit collection; The processor module being connected with each COMS imageing sensor.

Further, in order to store target contextual data, described in there is super-resolution reconstruction function CMOS camera and also comprise: the memory cell being connected with described processor module.

Technique scheme of the present utility model has the following advantages compared to existing technology: the utility model has solved under environment rugged environment by hardware means, the technical problem that resolution is low, carries out data acquisition to obtain super-resolution by the lens unit in fly eye lens array and corresponding COMS imageing sensor to same target scene.

Accompanying drawing explanation

For content of the present utility model is more likely to be clearly understood, below the specific embodiment by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein

Fig. 1 is the structural representation of CMOS camera of the present utility model;

Fig. 2 is four square lens unit distribution schematic diagrams of the present utility model;

Fig. 3 is the circuit block diagram of CMOS camera of the present utility model.

Wherein, 1 square lens unit, 2 COMS imageing sensors.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in detail:

See Fig. 1, a kind of CMOS camera with super-resolution reconstruction function, comprising: for gathering the fly eye lens array of target scene, this fly eye lens array comprises: four square lens units, and described four square lens units are square symmetrical; Be positioned at the COMS imageing sensor group of described fly eye lens array rear side, this COMS imageing sensor group comprises: four for receiving respectively the COMS imageing sensor of the target contextual data of each square lens unit collection; The same employing of these four COMS imageing sensors is square symmetrical, corresponding with described four square lens unit positions; With the processor module that each COMS imageing sensor is connected, this processor module is for extracting the pixel of the target contextual data that each COMS imageing sensor obtains, more described each pixel is superposeed and processed with realize target scene reconstruction.

Because the target scene distance that CMOS camera is taken is all far, with respect to each square lens unit, its ken is almost completely identical, because four square lens units are closely close, so it is identical can regarding their ken as, overlap, so the target scene obtaining is also consistent.

Described have super-resolution reconstruction function CMOS camera and also comprise: be connected with described processor module, for storing the memory cell of the target contextual data after stack pixel.

Described COMS imageing sensor can adopt PC1030 CLCC COMS imageing sensor; Described processor module can adopt dsp chip, for example TMS320F2812; Or ARM chip, for example S3C2440.

Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection range of the present utility model.
