Description
Technical field
The present invention relates to the color measurements technical field, particularly a kind of color sampling device.
Background technology
The color sampling device of display screen employing at present mainly contains hand-held or stent-type.Color illuminometer as hand-held: the CL-200 of Konica Minolta, can gather luminance and chrominance information, wherein colourity comprises the color harmony saturation degree.
Adopt the hand-held color sampling device, during actual the test, the tester need be with the hand-held color sampling device near suitable distance before the display screen, press color again and gather button, carry out the color collection, after the collection that Shows Picture of this screen is finished, repeat top action again, finish the color collection that other screen Shows Picture.
Adopt the stent-type harvester, during actual test, the tester need move to color sampling device and support suitable position before the display screen, for the harvester that has optical lens, also will adjust focal length, to be adjusted good after, just can carry out the color collection.And repeat above action, finish the color collection that other display screen Shows Picture.
More than two kinds of color sampling devices have following defective or deficiency:
1) staff's workload and labour intensity are all bigger, because when tested system is big, image data, collection position are more, adopt the hand-held color sampling device, the staff needs long-time hand-held color sampling device to gather color data, strengthened staff's working strength like this, for higher collection position, then staff's labour intensity is bigger; Adopt the stent-type color sampling device, need repeatedly mobile color sampling device, then increased staff's workload.
2) the image data personal error is bigger, because no matter be hand-held or stent-type color sampling device, when gathering the color data of diverse location of different display screens or same display screen, all need the manual mobile color sampling device of staff, cause harvester different with distance between the display screen, then image data is also variant, thereby the people is the error that causes that image data is bigger.
3) bigger to the injury of staff's eyesight, because the hand-held color sampling device needs the staff near the display screen of being gathered, optical radiation for a long time will cause great injury to staff's eyesight.
In sum, hand-held color sampling device and stent-type color sampling device only are fit to mini system, the situation that collection point and image data are less.
Summary of the invention
The invention provides a kind of color sampling device, gather instability, the technical matters that error is bigger to solve the prior art color sampling device.
In order to realize goal of the invention of the present invention, the technical scheme of employing is as follows:
A kind of color sampling device, described device comprise color acquisition module and the adsorption module that is connected with the colourity acquisition module.
As a kind of preferred version, described adsorption module is a sucker.
As further preferred version, described adsorption module comprises first sucker and second sucker, and described first sucker is arranged on the left side of color acquisition module, and described second sucker is arranged on the right side of color acquisition module.
As further preferred version, described adsorption module also comprises the intake and exhaust piston that is arranged on the sucker.
As a kind of preferred version, described adsorption module is connected with the color acquisition module is vertical.
As a kind of preferred version, described color acquisition module comprises light collection module, signal processing module, central processing module and the display module that connects successively:
The light collection module is used for light signal is converted to current signal;
Signal processing module, the current signal that the light collection module is exported becomes voltage signal;
Central processing module control light collection module is gathered light signal, and the analog voltage signal that signal processing module is exported is converted to digital signal and is calculated as needed color information;
Display module shows the color information of being gathered light.
As further preferred version, described color acquisition module also comprises the lightlng hole that is connected with the light collection module.
As a kind of preferred version, described color information is a colourity, and described central processing module carries out analog to digital conversion and calculates chrominance information the voltage signal of the output of signal-processing board.
As a kind of preferred version, described color information is brightness, and described central processing module carries out analog to digital conversion and calculates monochrome information the voltage signal of signal-processing board output.
When the present invention gathers in order to solve color, the problem of the manually fixing or stent support of instrument, a kind of sucked type color sampling device is provided, this device is easy to use, quick, the staff is promptly without the handheld test instrument, also need not move support, reduce staff's labour intensity and workload, reduce personal error.

Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Below describe with the colourity collection, color sampling device is selected the colourity harvester for use, and the colourity of display device is gathered.
The embodiment of the invention is a kind of colourity harvester, and described device comprises colourity acquisition module and the adsorption module that is connected with the colourity acquisition module.
Be illustrated in figure 1 as embodiment of the invention sucked type colourity harvester synoptic diagram.
Because display unit adopts advanced screen, each screen is smooth as mirror, so adopt the sucked type structure, whole harvester is adsorbed on the screen that needs test.Each harvester is equipped with two suckers, and the weight that each sucker can bear is 8kg, and the weight of whole harvester is 0.2kg, so the sucked type structure can satisfy the load-bearing requirement fully.In addition this sucker has air inlet, exhaust pition, fixedly during the colourity harvester, piston is in place, and at the needs collection position, presses this harvester; When taking off the colourity harvester, pull out piston, have a small amount of gas to enter sucker, the sucker absorption affinity diminishes, and takes off the colourity harvester.
The realization of colourity acquisition module is as shown in Figure 2:
Hardware realizes comprising following module: light collection module, signal processing module, data disaply moudle, central processing module.
The light collection module adopts the very color sensor of high-performance, gathers light signal, and light signal is converted to current signal.
Signal processing module, the current signal that the light collection module is exported becomes voltage signal, and carries out filtering and amplify.
Central processing module is finished controlling of sampling, analog to digital conversion, and algorithm process, and the enlargement factor of signal processing module adjusted data presentation control.
Display module shows the chrominance information of being gathered light.
The present invention uses simply, and is easy to operate, only needs following easy steps during use:
1) determines collection position.
2) install piston on the sucker, the present invention is aimed at collection position, press this device.
3) begin to gather.
4) collection is finished, and pulls out piston, takes off this device.
