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 device color representation of the present invention is shown, may further comprise the steps:
The hardware parameter of the display device that is obtained can comprise model, the time of making the product and the pairing performance parameter of this model etc. of current display device.The display device of indication of the present invention can be that display, video card etc. are used to the user that the equipment of Presentation Function is provided.
Be appreciated that before testing, can set up the database of a correspondence in test macro, the pairing various performance parameters of the model of existing main flow display device and this model are as hardware parameter on the current market of user storage.When needs are tested, then can directly from database, extract the hardware parameter of current display device.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 hardware parameter to server by system login.
Wherein, the color representation test is that the test sign is provided with in the diminishing mode of visible difference with background, and by the user color representation ability is tried to achieve in the identification of visible difference.The test sign can be the test-strips of color gradient, and the background of this moment can refer to other test-strips adjacent with a certain test-strips.The test sign also can be the constant test-strips of color that places a certain interface, the background of this moment promptly is meant the interface at test-strips place, in such cases, the test sign is to dwindle gradually and can realize by the identification and the resolution that change test-strips with the visible difference of background, also can realize, for example give ash that test sign or background increase different transparencies etc. by the identification and the resolution that change background
The kind of test sign can be determined according to the color of concrete required test, be designated the test-strips of color gradient for test, if need test gray scale, red, blue, green, test sign so can be four kinds, be designated example with red test, it can comprise some color bars of red gradual change.For the test sign also can be to have same color, but the test-strips of sharpness and identification gradual change, as literal bar or figure, can place the test sign under the different backgrounds this moment, the kind of test sign is determined according to the background color that it placed, to carry out the color test.Generally speaking, can choose gray scale and three primary colors (red, green, blue) totally four kinds of colors color as a setting respectively.Wherein, sharpness and identification gradual change can realize that the rgb value that also can change background color is realized by RGB (three primary colors) value that changes the test sign.
Wherein, the normal visible range of user can be the theoretic normal visible range that the hardware parameter according to display device calculates, and also can be the visible range under normal circumstances that draws by a large amount of experimental datas.During specific implementation, can adopt certain algorithm, when reality is used, can the display device of different model and different conditions be provided the scale corresponding with it.
When testing, the scale of the normal visible range of expression active user that is provided with under the test sign of various required tests can comprise the scale of the normal visible range of user that embodies described display device real-time status, and/or embodies the scale of the normal visible range of user of described display device optimum condition.
Wherein, the scale that embodies the normal visible range of user of described display device real-time status is meant, according to the hardware parameter of display device, has considered factors such as its real-time service time, represents the scale of current display device actual state.For example, for same color, but the test of the literal bar of sharpness and identification gradual change or figure sign, under a certain background, from left to right be arranged with 40 literal bars that sharpness and identification reduce gradually, suppose to draw according to the hardware parameter of the current display device that is extracted, considered equal loss's service time of current display device, in theory for the user, normal visible range is preceding 20 literal bars, so just, can provide a scale, represent that preceding 20 literal bars are the normal visible range in the current background.When the user when testing, just can come the existing certain understanding of the color table of employed display device according to set scale.For example, as seen can only see the 10th literal bar at most clearly for normal, illustrate that so the color representation ability related hardware parameter of current display device is adjusted, till seeing the 20th literal bar clearly as if the user if scale shows preceding 20 literal bars.
By hardware parameter the scale of representing normal visible range is set, has considered the otherness of display device, thereby made the scale that provides have reference significance preferably, avoided user's correlation parameter blindly to adjust display device in conjunction with display device.For example, for a time of making the product early, used display device for many years, may influence its display effect because of the relation of time and production technology at that time.Display device so hereto, user's normal visible range then may have only 10 the test signs in front, if the user can see the 10th test sign, suppose not to be provided with scale, the user may think that the test that can see clearly identifies very little so, the parameter of display device needs to adjust, but by with the contrast of scale, just can know and to adjust current parameter, thereby avoided user's blindness operation, also can make display device have good display simultaneously.
The scale that embodies the normal visible range of user of described display device optimum condition is meant, for the hardware parameter of current display device, does not consider factors such as its real-time service time, represents the scale of current display device optimum condition.For example, still being designated example with 40 literal bars of sharpness and identification gradual change under the aforesaid same background color as test describes, suppose that the normal visible range when hardware parameter according to display device calculates the best user mode of this display device is preceding 38 literal bars, if the user can see preceding 38 literal bars, perhaps preceding 36,37 literal bars, illustrate that current display device is in a preferable state, if the user can only see preceding 25 literal bars, after perhaps adjusting for the parameters of every display device, still can only see preceding 25 literal bars, illustrate that then current display device no longer has been in a preferable state, situations such as aging may occur.The scale of the normal visible range by optimum condition is set can make the user for the real-time status of the display device of oneself more objectively understanding be arranged, also can be comparatively objective when carrying out the related hardware parameter adjustment, avoid occurring blindly adjusting.
Be appreciated that, can be provided with simultaneously for the scale of the normal visible range of user of aforementioned embodiment display device real-time status and the scale that embodies the normal visible range of user of display device optimum condition, also the one setting can be selected, the required scale of user can also be provided according to user's requirement.
With reference to Fig. 2, the method for testing embodiment two of display device color representation of the present invention is shown, after the step 102 of embodiment one, increase following steps:
For test sign is the situation that places the constant test-strips of the color at a certain interface, because the color distortion of various interfaces background, the normal visible range of same display device under different background also difference may occur, so when scale is set, except considering the hardware parameter of current display device, can also be also as a reference with current background color, by the scale under the current background being adjusted, thereby make the represented normal visible range of scale more accurate in conjunction with display device hardware parameter and background color.
Be appreciated that step 102 and step 201 also can merge for the test sign that adopts in the present embodiment, promptly when scale is set, just considers the hardware parameter and the background color of display device simultaneously, thereby directly just can provide scale, need not after providing scale, to adjust again.
Generally, mostly be test to gray scale and Red Green Blue for the test of display device color representation, 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.Certainly, can also change according to concrete needs for background color, for example, the color that can increase other is as test.The user can understand the virtual condition of display device or judge whether and need adjust the related hardware parameter by scale set under each background color, and the desired value that needs adjustment, in the time can both seeing the indicated normal visible range of scale after the parameter adjustment under all background colors, illustrate that then the display effect of display device has been in a level preferably.
With reference to Fig. 3, the test macro of the display device color representation of the embodiment of the invention one is shown, comprise that parameter acquisition module 10 and scale are provided with module 20.
Scale is provided with module 20, is used for being provided with in a plurality of test signs of color representation test according to the hardware parameter that is obtained the scale of the normal visible range of expression user.
With reference to Fig. 4, the color test system for display device of embodiments of the invention two is shown, further, color test system for display device also comprises scale adjusting module 30, is used in conjunction with display device hardware parameter and background color the scale under the test sign of current background being adjusted.
With reference to Fig. 5, the color test system for display device of embodiments of the invention three is shown, further, color test system for display device comprises that also database sets up module 40, be used to set up the database of storage display device hardware parameter, parameter acquisition module 10 is set up the database that module 40 set up from database and is obtained hardware parameter.Described display device can comprise that display or video card etc. are used to realize the equipment of Presentation Function.
The method of testing of display device color representation of the present invention and system are at the scale that can set out the normal visible range of user under the expression current background color before the test in conjunction with the hardware parameter of current display device, wherein, the scale of the normal visible range of user can be the scale of expression display device real-time status, also can be the scale of expression display device optimum condition, certainly, aforementioned two kinds of scales also can exist simultaneously.The user can referential expression display device real-time status scale the related hardware parameter is adjusted, thereby make display device have good display.Simultaneously, the scale of expression display device real-time status has prompting user's effect, can make the user have objective understanding for display device, avoids occurring blindly adjusting.The user also can referential expression display device optimum condition scale judge situations such as the whether appearance of current display device is aging, the hardware condition of display device is had objective understanding.
In addition, the scale of two kinds of forms that provide has not been considered hardware parameters such as the time of making the product of display device, model, can provide different scales according to different display devices, thereby make the represented scope of scale comparatively reasonable.
Further, when the literal bar that adopts same color or figure during as the test sign, because the test sign is arranged under the different background color, when providing scale, as one of them reference factor, also can make the represented scope of the scale that provides more reasonable accurately the current background color.
Each embodiment in this instructions all adopts the mode of going forward one by one to describe, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.For system embodiment, because it is similar substantially to method embodiment, so description is fairly simple, relevant part gets final product referring to the part explanation of method embodiment.
