Description
Technical Field

Background
In the field of medical display, the medical display has higher requirements on technical parameters such as color reproduction, brightness, resolution and the like than the common civil display. Meanwhile, with the development of technology, medical images contain more and more abundant information, especially the wide application of medical images such as 4K and 8K, and the requirement of medical diagnosis on accurate restoration of color representation of a medical display is more and more strict. Generally, a conventional medical display displays all colors in a fixed color space (such as an RGB color space), but does not support some other color spaces (such as an LAB color space) more suitable for medical image diagnosis, thereby bringing limitations of the medical display in medical image diagnosis.
In today's applications such as multimedia, the images being compared and rendered may be from two disparate sources of input devices or may be rendered on two disparate output devices such that the resulting color representations for the same scene are not identical. For example, the same image in the network may be downloaded to the user's computer or may be hard-copied for output by a printer. Because different computers and different condition settings have different expressive abilities on digital images, the colors expressed by different types of output equipment are greatly different, and great difference of color expression can be formed.
Medical display market demand has been increasing, with color displays occupying a large share of the market in the medical screen industry, with the largest portion of color displays being used for various diagnostic imaging purposes.

TMDS signals, i.e. transition modulation differential signals, also called transition minimized differential signals, refer to converting original signal data into 10 bits by an exclusive or and exclusive or equal logic algorithm, the first 8 bits of data are obtained by the original signal after operation, the 9 th bit indicates the operation mode, the 10 th bit is used to correspond to DC-balanced (DC-balanced, which means that DC offset in a channel is guaranteed to be zero during encoding, level conversion realizes matching between different logic interfaces), and the converted data is transmitted in a differential transmission mode.
The LVDS is low voltage differential signal, the core of the technology is that data is transmitted differentially at high speed by adopting extremely low voltage swing, point-to-point or point-to-multipoint connection can be realized, the technology has the characteristics of low power consumption, low error rate, low crosstalk, low radiation and the like, and a transmission medium can be a copper PCB connecting wire or a balanced cable. LVDS is finding increasingly widespread use in systems requiring high signal integrity, low jitter, and common mode characteristics.
Referring to fig. 4, in the step 9, the bridge module is an IT6263 bridge chip, the IT6263 bridge chip is a high-performance one-chip microcomputer De-SSC LVDS-to-HDMI converter, an internal IIC protocol interface is used to configure ITs internal register correspondingly, and the IT6263 combines with an LVDS receiver and an HDMI transmitter to support the LVDS input and the HDMI1.3 mutual conversion output.
Referring to fig. 2, in the step 202, common color space models including an RGB model, an HSV model, a YUV model, an LAB model, and a CMYK model are set.
The RGB model, i.e., the RGB color model, is a color standard in the industry, which obtains various colors by the variation of three color channels of red (R), green (G), and blue (B) and their mutual superposition, where RGB represents the colors of the three channels of red, green, and blue, and this standard almost includes all colors that can be perceived by human vision, and is one of the most widely used color systems at present.
The HSV Model (Hue, Saturation) is a color space created by a.r. smith in 1978 based on the intuitive properties of colors, also called the hexagonal cone Model (Hexcone Model), in which the parameters of the colors are: hue (H), saturation (S), lightness (V).
YUV model, YUV is a color coding method (belonging to PAL) adopted by European television system, and is a color space adopted by PAL and SECAM analog color television system. In a modern color television system, a three-tube color camera or a color CCD camera is usually used for image capture, then the obtained color image signals are subjected to color separation and respective amplification and correction to obtain RGB, and then a luminance signal Y and two color difference signals B-Y (i.e., U) and R-Y (i.e., V) are obtained through a matrix conversion circuit, and finally a transmitting end respectively encodes the luminance signal and the color difference signals and transmits the encoded signals through the same channel. This color representation is called YUV color space representation. The importance of using the YUV color space is that its luminance signal Y and chrominance signal U, V are separate.
The LAB model and the Lab color model are composed of three elements of brightness (L) and related colors a and b. L represents lightness (luminescence), a represents a range from magenta to green, and b represents a range from yellow to blue. The value range of L is from 0 to 100, and when L is 50, the color is equivalent to 50% of black; the value ranges of a and b are from +127 to-128, wherein the +127a is red, and the green color is changed when the value range is gradually transited to-128 a; in the same principle, +127b is yellow and-128 b is blue. All colors are composed by alternating changes of these three values. For example, a block color has a Lab value of L-100, a-30, b-0, and is pink. (Note: the a-axis, b-axis colors in this mode are different from RGB, magenta is more reddish, green is more cyan, yellow is slightly reddish, and blue is somewhat cyan).
The CMYK model, i.e., the four-color printing mode, is a color register mode used in color printing, and forms so-called "full-color printing" by mixing and superimposing four colors in total using the principle of mixing colors of three primary colors of color materials and black ink. The four standard colors are: c: cyan, also known as sky blue or blue; m: magenta, also known as Magenta; y: yellow; k: blacK is blacK and although the literature explains that K should be Key Color, it is confusing with the registration process concept used in plate making. The abbreviation K is used here instead of the first B in order to avoid confusion with Blue. The CMYK mode is a subtractive color mode and the corresponding RGB mode is an additive color mode.
Referring to fig. 2, in the step 203, the color modes are in one-to-one correspondence with the color space models.
Referring to fig. 4, the present embodiment further provides a system for implementing the method for supporting separate color correction of multiple display devices with the same signal, which is characterized by comprising:
