Description

Technical Field

[0001] The utility model relates to the technical field of digital color calibration, in particular to a digital color calibration device. Background Art

[0002] A digital color calibration device usually consists of two parts: a hardware colorimeter and software. The hardware part mainly includes a photometer (used to measure radiation intensity) and possible mechanical structures (such as the telescopic mechanism of a built-in colorimeter); the software part is responsible for controlling the color calibration process, data analysis, and color adjustment. A digital color calibration device achieves accurate correction of the display color by measuring and comparing the color performance of the display, and adjusting the RGB response curve in the graphics card LUT based on the comparison results. Some existing digital color calibration devices are suspended on the front side of the display through data cables, so that the digital color calibration device is in contact with the display to achieve digital color calibration of the display. This type of digital color calibration device is suspended through a data cable, and there is a gap in the contact between the digital color calibration device and the display. The entry of external light will have a certain impact on the collection of color data of the display by the photometer, and will have a certain impact on the final color calibration effect of the display. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a digital color calibration device, comprising a color calibration chamber and an elastic clamping mechanism;

[0006] Elastic clamping mechanism: It is rotatably connected to the end of the adjustment tube away from the center of the color calibration bin, so as to quickly adjust the spacing of the elastic clamping mechanism. At the same time, the spring force makes the color calibration bin fit closely with different displays, effectively ensuring the accuracy of the digital color calibration of the display.

[0007] Furthermore, the elastic clamping mechanism includes a clamping seat, a sliding rod, a support plate and a clamping plate. The clamping seats are rotatably connected to one end of the adjustment cylinder away from the center of the color calibration bin. The interior of the clamping seat is provided with evenly distributed sliding openings, and the interiors of the sliding openings are slidably connected with sliding rods. The lower ends of three laterally adjacent sliding rods are fixedly connected with the clamping plate, and the upper ends of three laterally adjacent sliding rods are fixedly connected with the support plate, thereby realizing a stable connection between the color calibration bin and the display.

[0008] Furthermore, the elastic clamping mechanism also includes a spring, which is evenly and fixedly connected between the support plate and the longitudinally adjacent clamping seats. The springs are movably sleeved on the outer surfaces of the longitudinally adjacent sliding rods to provide driving force for the tight fit between the calibration chamber and the display.

[0009] Furthermore, the rear surface of the clamping seat and the front surface of the clamping plate are both provided with buffer pads to protect the display.

[0010] Furthermore, a photometer is provided inside the color calibration chamber, and the photometer is provided with a USB connector via a data cable. The photometer is bidirectionally electrically connected to the USB connector via the data cable to achieve digital color calibration of the display.

[0011] Furthermore, the front end of the color calibration bin is connected to a bin cover 1 by screws, and a light sensor is provided in the middle of the bin cover 1. The light sensor is also bidirectionally electrically connected to the USB connector through a data cable to sense ambient light and assist in digital color calibration of the display.

[0012] Furthermore, the rear end of the calibration chamber is fixedly connected with symmetrically distributed cartridges, the interior of the cartridges are all clamped with cartridge posts, and the rear ends of the cartridge posts are fixedly connected with the front end of the second chamber cover to protect the camera of the photometer.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the digital color calibration device has the following advantages:

[0014] The adjusting cylinder is rotated in sequence, and the adjusting cylinder moves in the direction away from the color calibration bin under the action of the screw, and the clamping seat moves in the direction away from the center of the color calibration bin. When the clamping seat moves to the required position, the personnel stops rotating the adjusting cylinder, and then pulls the clamping plate backward, so that the sliding rods all move backward inside the corresponding sliding openings and drive the support plate to move backward. The spring is compressed, so that the clamping plate and the longitudinally adjacent clamping seats work together, and the rear side surface of the color calibration bin is tightly fitted with the display to adjust the spacing of the elastic clamping mechanism. The spring elastic force makes the color calibration bin fit closely with different displays, which greatly improves the accuracy of the photometer in collecting the color data of the display, avoids the gaps in the process of suspending the digital color calibration device through the data cable, and thus avoids the influence of external light sources on the accuracy of the color data collection of the display.

[0023] Elastic clamping mechanism 5: It is respectively rotatably connected to the end of the adjustment tube 9 away from the center of the color calibration bin 1. The elastic clamping mechanism 5 includes a clamping seat 51, a slide bar 52, a support plate 54 and a clamping plate 55. The clamping seat 51 is respectively rotatably connected to the end of the adjustment tube 9 away from the center of the color calibration bin 1. The interior of the clamping seat 51 is provided with evenly distributed sliding openings, and the interior of the sliding openings is slidably connected with the sliding bars 52.

The two monitors are tightly fitted, and then the personnel connect the USB connector 12 to an external computer to operate the photometer 2 and the light sensor 10. The camera of the photometer 2 measures the radiation intensity of the color displayed on the display, and can accurately capture the brightness and chromaticity values ​​of the three primary colors of red, green and blue, providing basic data for subsequent color correction. At the same time, the light sensor 10 measures the light intensity of the surrounding environment. Based on the measured ambient light intensity, the light sensor 10 can assist the photometer 2 in adjusting the brightness, contrast and other parameters of the display to ensure that the color can maintain consistency and accuracy under different lighting conditions.
