Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the method for testing embodiment one of display color performance of the present invention is shown, may further comprise the steps:
In test process, each test is identified at shown sharpness and the identification that goes out of display and gradually changes with respect to the user, and for example, from left to right sharpness and identification reduce gradually.The user then can choose last the test sign that can see clearly according to the judgement of oneself.Wherein, each test is identified at the shown sharpness that goes out of display and identification gradually changes and can realize by the mode that test sign and the visible difference of background are dwindled with respect to the user, by the user color representation ability is tried to achieve in the identification of visible difference.For example, realize or change background color realizing by changing test indicating self color.The test sign can be literal, figure or color lump etc.Concrete, aforesaid background can refer to test the background at sign interface, place, being about to the test sign places under some color background, it also can be test sign itself, promptly, the color lump that adopts color gradient is as the test sign, and other test signs adjacent with a certain test sign can be considered to background.
For example, the literal bar that is designated the gray scale gradual change with test is an example, when test, multiple color background can be set, the test sign of gray scale gradual change is set under each color background, the user can choose clearly last test sign of institute under each color background, system can draw the current color representation ability of display according to the sharpness and the identification of user-selected test sign of getting.For example, for color representation ability display preferably, the user may be able to see rightmost clearly or near rightmost test sign, and for the general display of color representation ability, the test sign in the middle of the user then may can only see clearly.Generally, mostly be test to gray scale and Red Green Blue for the test of display color, so, four background colors can be set in the present embodiment, that is, and ash, red, green, blue.Wherein, the sequencing of four background colors does not limit, and can determine arbitrarily.When the user is choosing the test sign under a certain color background after, then enter the interface of next color background automatically, after the user had chosen test sign under all color backgrounds, system calculated the current color representation ability of display automatically according to user's selection result.Certainly, can also change according to concrete needs for color background, for example, the color that can increase other is as test.
The detailed process that draws the current color representation ability of display can be determined as required, for example, suppose to have four kinds of background colors, be respectively ash, red, green, blue, under each color background, 40 test signs are all arranged, if the user in following the test that can see sign of different color backgrounds is respectively: grey, the 38, redness, the 35, green, the 30 and blue, the 33.Can the first-selected numerical range of determining different color representation abilities, then test result is calculated, obtain the test value under each color background, be the color representation ability of current display.
Further, in order to make the user objective understanding be arranged for the color representation ability of display, can also be after testing out the color representation ability of current display, the color expressive ability is classified according to certain grade, as, excellent, good, in, difference or can represent that with low-grade, general, outstanding, superfine product etc. grade other classification represents.Concrete number of levels can be determined according to actual needs, for example, calculates for convenience, simplifies flow process, grade just can be defined as four, if in order to obtain result more accurately, also refinement grade further.In addition, also can proportionally represent the grade of color representation ability, for example, a few percent of the current optimal representation that reaches system default.For example, after measuring four test values under the color background, can be directly with the four number additions that test out under four color backgrounds, drawing calculated value is 136, if the color representation ability is divided into four grades, the numerical range of each grade is respectively: low grade, one to 40; Generally, 41 to 80; Outstanding, 81 to 120; Superfine product, 121 to 160.Can draw so, the color representation ability rating of current display belongs to superfine product.
Behind the test value that tests out the current color representation ability of display, the model of the model of the automatic extraction of system's meeting display or the video card corresponding with current display, and according to this display that prestores or the pairing reference color parameter of video card, in conjunction with the test value of the current color representation ability of the display that tests out, calculate again with reference to adjusted value.Suppose, the pairing reference color parameter of current display is: brightness, 50, contrast, 51, red color is 60, green colourity is 70, chroma blue is 40, and the test value of the color representation ability of display is: brightness, 40, contrast, 46, red color is 60, green colourity is 70, chroma blue is 40, so according to pairing reference color parameter of display and current color representation ability, drawing with reference to adjusted value then can be existing display brightness to be heightened 10 gears and contrast is heightened 5 gears etc.When carrying out the color test, the situation that a certain color colourity need be adjusted also can appear, and for example red benchmark colourity is 60, and the red test colourity of display is 50, the reference adjusted value that draws so then is that red color is heightened 10 gears.
Be appreciated that before testing, can in test macro, set up the database of a correspondence, be used for the reference color parameter of storage representation display reference color performance.Wherein, the reference color parameter can be the pairing reference color parameter of existing main flow display model on the current market, and/or video card pairing reference color parameter under current display model.The reference color parameter generally includes these several parameters of brightness, contrast and three primary colors (red, green, blue).After test is finished, can directly from system, extract current display and/or video card pairing reference color parameter under current display model, then in conjunction with the test value of the current color expressive ability that tests out, thereby can provide the reference adjusted value that is fit to current display expressive ability.The data of database can be upgraded in real time by modes such as upgradings, to satisfy requirements of different users.Certainly, also database directly can be deposited on server, when the user needs, can read correlation parameter to server by system login.
