Embodiment Construction

[0042] The present invention will be further described below in conjunction with specific embodiments.

[0043] Such as figure 1 and Figure 5As shown, the present invention provides a color difference analysis method and a display with color difference analysis function, wherein, a display with color difference analysis function includes: PL module 14, PS module 12, FLASH storage unit 11, liquid crystal display panel 15. When performing color difference analysis, the display needs to be connected with an external colorimeter 16, and in actual implementation, the colorimeter 16 can also be replaced by a photometer.

[0044] In the present embodiment, the PS module 12 and the PL module 14 are realized by using the ZYNQ chip of xilinx. The PS module 12 is generally called a programmable system, and is composed of a SoC (system on chip / system-on-chip, System on Chip) of the ARM architecture. In this embodiment, the PS module 12 runs an operating system of the Linux kernel to dr...

Abstract

The invention discloses a color difference analysis method which comprises the following steps: 1, constructing a color set with the number of colors not less than 20, the color set comprising 100% white, 100% red, 100% green, 100% blue, 100% cyan, 100% magenta and 100% yellow; 2, measuring color lumps displayed by a display to obtain CIEXYZ measured values; 3, converting the CIEXYZ measured values of seven colors in the CIEXYZ measured values in the step 2 to obtain CIEXYxy measured values, and taking an x component and a y component in the CIEXYxy measured values as chromaticity coordinatesof the seven colors in a CIEXy coordinate system; 4, converting all RGB color values in the color set into CIEXYZ reference values; 5, respectively converting the CIEXYZ measured values and the CIEXYZreference values into CIELab measured values and CIELab reference values; and 6, calculating the chromatic aberration between the CIELab measured values and the CIELab reference values. Meanwhile, the invention provides a display with a color difference analysis function. The color of the display can be visually and efficiently evaluated only by externally connecting a colorimeter, color difference calculation can be more accurate, and an evaluation result is more objective and real.

Description

technical field [0001] The invention belongs to the field of video display, and more specifically relates to a color difference analysis method and a display with a color difference analysis function. Background technique [0002] In the radio, television and film and television industries, it is necessary to ensure that the color of the display in the video production process is basically consistent. For example, in high-definition video production, it is necessary to ensure that the color gamut of the display is Rec.709. It is generally necessary to evaluate the color of all monitors, and then perform color correction on monitors with inaccurate colors, or directly replace the monitor. [0003] Generally, the color of the display is evaluated by the following methods: [0004] Comparative observation method: Find an absolutely standard monitor as the reference, and then input various test signals to the monitor at the same time, and the observer can judge whether the colo...
