Abstract
The utility model relates to a kind of camera module chromatism test figure card device, it comprises figure clamp and color lump, figure clamp is provided with groove, the bottom of color lump is provided with the projection with groove match, color lump is plugged on figure clamp by projection, and the planar dimension of figure clamp is 305mm × 105mm, and the planar dimension of color lump is 45mm × 45mm, grafting 12 color lumps on figure clamp, the interval 5mm between adjacent two color lumps.The utility model, reduces costs, and increases the service life, and is convenient for carrying, and it is precisely convenient to test, and is suitable for cell-phone camera module.
Description
Technical field
The utility model relates to a kind of test pattern device, particularly relates to a kind of camera module chromatism test figure card device, is applicable to the color restoration capability test of digital photographing equipment.
Background technology
The color restoration capability (aberration) of digital photographing equipment is one of important indicator of its equipment performance of inspection.The inspection color in common use test pattern of color restoration capability.The color test pattern of current employing is planar card, and during use, if there is each color lump to wear and tear, whole card needs to change, and cost is higher, and useful life is short, and carries inconvenience.
Utility model content
The utility model is for above-mentioned problems of the prior art, provide a kind of camera module chromatism test figure card device, solve the problem that in prior art, chromatism test graph card cost is higher, useful life is short, and the utility model is easy to use, steady quality.
The technical solution of the utility model is as follows:
Comprise figure clamp and color lump, figure clamp is provided with groove, the bottom of color lump is provided with the projection with groove match, color lump is plugged on figure clamp by projection, the planar dimension of figure clamp is 305mm × 105mm, the planar dimension of color lump is grafting 12 color lumps on 45mm × 45mm, figure clamp, the interval 5mm between adjacent two color lumps.
12 described color lumps are arranged as two row six row at figure clamp.
12 described color lumps are measure-alike.
Described graph card sleeve-board is equipped with box body.
The utility model has the advantages of as follows:
The utility model, by planar card is made three-dimensional connected structure, if when the problems such as wearing and tearing appear in one of them color lump, is changed separately wearing and tearing color lump, is reduced costs, increase the service life.Meanwhile, be contained in box body, be convenient for carrying graph card sleeve-board, it is convenient to test, and is suitable for cell-phone camera module.
Through lot of experiments checking, graph card board size and color lump size are carried out above-mentioned concrete restriction, the color accurate testing of cell-phone camera module can be made, conveniently intercept comparison.
The utility model scope of application is wide, and easy to operate, cost is lower, steady quality, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, figure clamp, 2, color lump.
Embodiment
The utility model, with reference to accompanying drawing, in conjunction with specific embodiments, is described in detail as follows.
Embodiment
As shown in Figure 1, comprise figure clamp 1 and color lump 2, figure clamp is provided with groove, the bottom of color lump is provided with the projection with groove match, color lump is plugged on figure clamp by projection, the planar dimension of figure clamp is 305mm × 105mm, the planar dimension of color lump is 45mm × 45mm, on figure clamp, 12 color lumps of grafting are arranged as two row six row, 12 color lumps comprise 6 grades of gray scale color lumps and blue, green, red, yellow, purplish red, bluish-green 6 color lumps, interval 5mm between adjacent two color lumps, 12 color lumps measure-alike.
Described graph card sleeve-board is equipped with box body.
During test, arrange requirement by test, camera module chromatism test graph card is taken, by captured image input computer.Get 1-3 tri-color lumps, in every color lump, intercept the color lump that area is not less than 30%, measure test pattern and three cut-away view respectively as the rgb value of color lump with photoshop and be converted to CIE L*a*b* value, bring following formula into and calculate color rendition error:
Luminosity equation △ L*=L1*-L2*
Colour difference △ a*=a1*-a2*
△b*?=?b1*-b2*
Color rendition error delta EL*a*b*=[(△ L*) 2+ (△ a*) 2+(△ b*) 2] ﹙ △ EL*a*b* color error units)
In formula, L1*, a1*, b1* are lightness and the chromatic value of test pattern.
L2*, a2*, b2* are lightness and the chromatic value of photographic images.
Protection range of the present utility model not limit by specific embodiment, is as the criterion with claims.
