Embodiment
Referring to shown in Figure 1, a kind of display screen color adjusting gear, described device comprises main body 101, and is arranged on interconnective color detection module 102 and main control module 103 on the main body 101;
Described main body 101 comprises frame 101-3, be arranged on the power body 101-1 of frame 101-3 both sides and be arranged on a plurality of sucker 101-2 on the power body 101-1, and power body 101-1 drives sucker 101-2, and sucker 101-2 can be adsorbed on display screen surface;
Described power body 101-1 comprises: a pair of front and back wheel and the crawler belt that is wrapped on the front and back wheel, described front and back wheel can be rotatably set in the both sides of frame 101-3, described sucker 101-2 is arranged on the crawler belt, sucker can be adsorbed on the glass curtain of display screen, and can drive adjusting gear at least and move along two or more directions;
Described color detection module 102 is installed on the mobile device 101, and can directly touch display screen, and it is provided with color sensor, optical filter, reaches optical lens (not having sign among the figure), is used to measure the color parameter of display screen;
Described main control module 103 is used to control mobile device and moves at the assigned address of display screen and carry out color measuring, calculating, calibration of display screen etc.
Described communication module 104 is used for carrying out communication with display device controller, and calibration data etc. is set.
Use the method for operating of this display screen color adjusting gear to comprise the steps:
(1) all display screens is set and shows specific picture.As, each picture all comprises three kinds of primary colours zones of red, green, blue;
(2) main control module calculates the current location of mobile device in a certain display screen, and mobile device is automatically moved to red, green, blue zone in this display screen respectively;
(3) by the color detection module, measure the color value on the red, green, blue zone respectively, and record, realize the transmission of data by communication module, adjust the color parameter of display screen respectively, make the color value that measures respectively with predefined with reference to color value conform to (allowing certain error);
(4) mobile device is automatically moved to next display screen, repeating step (2), (3);
(5) finish the adjustment of all display screens.
Wherein, in the described step (1), the demonstration particular picture that present embodiment adopts all comprises three kinds of primary colours zones of red, green, blue, as shown in Figure 2, is the display splicing unit of a 2*2, and each display screen shows particular picture.The particular picture that shows display screen adopts display screen to show the picture of three kinds of primary colours of red, green, blue successively.
If adopt each display screen to show the picture of three kinds of primary colours of red, green, blue successively, can skips steps (2), directly enter step (3), promptly by the control display screen picture of three kinds of primary colours of red green and blue successively, directly carry out the measurement of color value with the color detection module, do not need mobile device to move and find corresponding color region.
In the described step (2), main control module 103 calculates the current location of mobile device 101 in a certain display screen, can realize by following method: referring to shown in Figure 3, show a horizontal white stripes by being set in the display screen bottom, move to the top by the bottom, and the color detection module does not stop to survey color value, till the color detection module detects white stripes 301, detect mobile device 101 in the lengthwise position y of display screen value, same, the left side or the right side that are set in display screen show a longitudinal stripe, move to relative opposite side, and the color detection module does not stop to survey color value, till the color detection module detects white stripes 302, detects mobile device in the lateral attitude of display screen x value.One of method that this just realizes, the present invention calculates the current location of mobile device in a certain display screen and is not so limited.
Calculate the current location (x of mobile device in a certain display screen according to main control module, y), and the detected color value of current location, the color sequences of setting in conjunction with display screen that Shows Picture again, decision mobile device 101 still moves forward backward, realizes that with this mobile device is automatically moved to red, green, blue zone in this display screen respectively.
In the described step (3), described predefined with reference to color value, can rule of thumb set, adjust the display splicing unit that a plurality of display screens are formed, this value is arranged on the minimum in the highest color value that each display screen can reach usually, and for example, the highest HSV value after the quantification that display screen A shows is respectively (0.9,0.85,0.9); The highest HSV value after the quantification that display screen B shows is respectively (0.85,0.9,0.9); The highest HSV value after the quantification that display screen C shows is respectively (0.9,0.9,0.9); The highest HSV value after the quantification that display screen D shows is respectively (0.8,0.9,0.8).So, the reference color value is chosen the minimum of HSV respectively, and the final reference color value can be chosen to be (0.8,0.85,0.8).The reference color value can be kept in the main control module in advance.
Wherein said color parameter also can adopt color spaces such as other RGB, CMYK to represent, not limited by present embodiment.
By the color detection module, measure the color value on the red, green, blue zone respectively, and record, wherein, can each zone be taken multiple measurements average by setting a plurality of measurement points in each zone of red, green, blue as this regional color value.Only a measurement point is got in each zone of red, green, blue in the present embodiment, as the measurement point among Fig. 2 201, measurement point 202, measurement point 203, measure the color value on this zone, judge when whether the color value that measures conforms to predefined color value respectively, allow certain error, promptly in this error range, think that still the color value that measures conforms to reference to color value with predefined respectively.
By the transmission of communication module realization data, adjust the color parameter of display screen respectively, make the color parameter of each display screen conform to predefined reference color value.If the display screen color value that measures some display screen may occur and not reach predefined reference color value in the toning process, can be calibrated to immediate parameter, also can be further after all display screen calibrations be finished, according to record measure color value recomputate the new reference color value that all display screens all reach, and carry out primary calibration again; All be higher than predefined reference color value if occur the measurement color value of all colours screen after all display screen calibrations are finished, can also further calculate all screens of setting and can reach the highest of unanimity, carry out primary calibration again with reference to color value.
In the described step (4), mobile device is automatically moved to next display screen, repeating step (2), (3).For reducing mobile device displacement, can select to adjust all display screens according to order line by line, after having adjusted the display screen of high order end or low order end, select to adjust above it or following display screen, mobile device moves on display screen and only need carry out laterally or move longitudinally; For safety other a warning coloration can be set around each display screen, in case locking apparatus drops.The color in random color zone is different in the picture that described warning coloration and display screen show, when the color detection module detected warning coloration, master control module judges need cross other screens or arrive the border of whole mosaic display screen and stop to move.
The foregoing description is a preferred implementation of the present invention; but embodiments of the present invention are not limited by the examples; other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
