Description

A kind of infrared ray colored digital camera

Technical field

The utility model relates to a kind of colored digital camera, more particularly, relates to a kind of infrared ray colored digital camera.

Background technology

Common digital camera Optical devices are many to be made up of lens protection glass 1, lens assembly 21, aperture/shutter 3, low pass filtered light microscopic 4, infrared ray cut optical filtering 5, CCD or CMOS cover glass 6, CCD or CMOS photosensitive sensor 22, sees Fig. 1.

Ordinary numbers formula camera adopts spacing color mixed method, and each the photosensitive pixel place on the surface of its CCD or CMOS photosensitive sensor coats red (R), green (G), blue (B) filter layer respectively, sees Fig. 2, is exactly wherein a kind of distribution mode as shown in Figure 2.CCD or CMOS photosensitive sensor itself all can be experienced whole coloured light, after being subjected to the obstruct of red (R), green (G), blue (B) three metafiltration photospheres, the CCD of filter layer back or cmos pixel point, can only experience three kinds of coloured light of red, green, blue respectively, realize that directly three primary colors divide optical recording, image color is reduced to natural colour.

Modern colour phhotograpy, color film, color TV etc. reappear chromatic image all based on the three primary colors theory.With colored negative photosensitive sheet is example; colour negative is generally by protective layer 8; the blue layer 9 of sense; filter layer 10; green layer 11; sense red beds 12; binder course 13; sheet base 14; antihalation layer 15 is formed; see Fig. 3; it is blue that its photosensitive layer is divided into sense; feel green; feel red three layers; the inside is added the complementary color colour coupler respectively; promptly in the blue layer 9 of sense, add yellow colour coupler; in green layer 11, add magenta colour coupler; in sense red beds 12, add cyan colour coupler; after the negative film flushing; form yellow respectively; magenta and cyan image; people see is the Overlays of these three layers figure layer, i.e. negativity image, through the colour paper with similar wash be made into photochrome after; yellow on the egative film; magenta is resumed blue with the cyan image; green; red three layers of chromatic image promptly recover the natural colour of object after the stack.

Infrared ray is a ray invisible to the human eye; there is not color in people itself; but traditional infrared ray color sensitive sheet, it generally is made up of protective layer 8, sense infrared ray layer 16, green-light-sensing layer 17, red-light-sensing layer 18, binder course 13, sheet base 14, antihalation layer 15, sees Fig. 4.In sense infrared ray layer 16, contain cyan dye, in green-light-sensing layer 17, contain weld, in red-light-sensing layer 18, contain magenta look dyestuff, be that traditional infrared ray color sensitive sheet still is designed to three layers of photosensitive layer, be respectively sense infrared ray layer 16, green-light-sensing layer 17, red-light-sensing layer 18, the people can form artificial false color for setting toner for for yellow, magenta and cyan coupler after the flushing.

The utility model content

Technical problem to be solved in the utility model provides a kind of infrared ray colored digital camera simple in structure, and this infrared ray colored digital camera will finally to wash the photochrome color of gained identical with conventional red outside line color camera.

In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:

A kind of infrared ray colored digital camera comprises body, is provided with Optical devices on body, and described Optical devices comprise lens assembly, ccd sensor or CMOS photosensitive sensor; The photosensitive pixel that being used to of described ccd sensor or CMOS photosensitive sensor generates red image is the photosensitive pixel that scribbles the filter layer of infrared ray resistance visible light; Being used to generate also add on the photosensitive pixel that is coated with green filter layer of blue image and scribbling low pass filtered light microscopic layer at described ccd sensor or CMOS photosensitive sensor; Being used to generate also add on the photosensitive pixel that is coated with red filter layer of green image and scribbling low pass filtered light microscopic layer at described ccd sensor or CMOS photosensitive sensor.

The utility model is owing to adopted said structure, compare with conventional art, in the utility model, the photosensitive pixel of each bluing filter layer of CCD or CMOS photosensitive sensor is changed into the photosensitive pixel of the filter layer that is coated with infrared ray resistance visible light, it is used to generate red image, the photosensitive pixel that each of CCD or CMOS photosensitive sensor is coated with green filter layer adds the low pass filtered light microscopic layer that is coated with ordinary digital camera, be used to generate blue image, the photosensitive pixel that each of CCD or CMOS photosensitive sensor is coated with red filter layer adds the low pass filtered light microscopic layer that is coated with ordinary digital camera, be used to generate green image, so according to traditional color transparency and the photochrome color relation of complementary color each other, infrared ray colored digital camera of the present utility model will finally to wash the photochrome color of gained identical with conventional red outside line color camera, in addition, the utility model is simple in structure.

After the detailed description of reading execution mode of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.
