It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
It will be appreciated by those skilled in the art that the configuration shown in fig. 1 does not constitute a limitation of the color conversion device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a color conversion program.
In the color conversion apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the color conversion apparatus of the present invention may be provided in the color conversion apparatus which calls the color conversion program stored in the memory 1005 through the processor 1001 and executes the color conversion method provided by the embodiment of the present invention.
An embodiment of the present invention provides a color conversion method, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a color conversion method according to the present invention.
In this embodiment, the color conversion method includes the following steps:
step S10: and acquiring a perception setting instruction of a user.
It should be noted that the execution subject of the present embodiment may be a terminal device including a color display screen, such as a television or a display.
It can be understood that the color vision disorder of each user is different, and therefore, the display scheme is specifically formulated according to the condition of each user. Therefore, when a display scheme is formulated, different preset color pictures need to be displayed to a user to determine the color vision disorder type of the user, for example: when the user is anerythrochloropsia, the user cannot distinguish green from orange, and the color vision disorder type of the user can be obtained by selecting the preset color picture which cannot be distinguished by the user.
It should be noted that, when the user is a specific color vision disorder type, the colors cannot be distinguished because of the corresponding type, and when the user is anerythrochloropsia, the user cannot distinguish the colors of the green color system and the red color system, but when the user is anerythrochloropsia, not all the colors of the green color system and the red color system cannot be distinguished, and the sensitivity of the user to the color is different for each color vision disorder type, and therefore, further measurement of the color sensitivity of the user is required.
In a specific implementation, different colors in the same series need to be displayed to the user, and the perception setting instruction of the user is generated according to the perception colors selected by the user.
Step S20: and determining the color vision disorder degree of the user according to the perception setting instruction.
Further, step S20 includes: obtaining the color vision disorder type of the user according to the perception setting instruction; obtaining the color vision offset of the user according to the perception setting instruction; and determining the color vision disorder degree of the user according to the color vision disorder type and the color vision offset.
It is understood that the perception setting instruction includes the type of dyschromatopsia of the user, such as red achromatopsia, green achromatopsia, blue achromatopsia, and the like.
It should be noted that, according to the perception degree of the color vision disorder by the user, the color vision offset of the user may be determined, for example: the cell of human eye perceiving red is red cone cell, because the peak wavelength range of red cone cell is 564nm-580nm, so if the L cell, that is, red cone cell response curve shifts 30nm, it is essentially unable to distinguish red, according to the user's choice of perception color, can determine the user's color sensitivity, thus determine the user's offset of color cone cell.
In particular implementations, the dyschromatopsia level represents the sensitivity of a dyschromatopsia user to dyschromatopsia colors, e.g., a red dyschromatopsia user, with the dyschromatopsia level normalized to
Figure BDA0002869876670000061
When his color vision shift is 30, i.e. alphaRIs 1, is a color blind user, when the color vision offset is less than 30, namely alphaRAnd when the color intensity is less than 1, the user is a color-weak user.
The peak wavelength ranges of the green cone cells, i.e., M cells, are: 534nm-555nm, so if the response curve of the green cone cells deviates 30nm, the green cone cells can not be basically distinguished, and the degree of the green dyschromatopsia can be normalized to be
Figure BDA0002869876670000062
Since the peak wavelength range of S cells, i.e. blue cone cells, is: 420nm-440nm, the wavelength range of S cells is: 400nm-500nm, so that blue color can not be sensed by shifting 60nm, and the degree of blue color dyschromia can be normalized
Figure BDA0002869876670000063
It can be understood that the color vision disorder condition of the user, which is reflected comprehensively by the color vision disorder degree, can be corrected according to the color vision disorder degree of the user.
Step S30: and determining a corresponding color disorder mode according to the color vision disorder degree.
Further, step S30 includes: determining a preset conversion ratio according to the color vision disorder degree;
and determining a corresponding color disorder mode according to the preset conversion ratio and the color vision disorder degree.
It should be noted that different color vision disorder degrees may correspond to different preset conversion ratios, and the preset conversion ratio is used to convert the color type that is not perceived or is less perceived by the user into the color type that is perceived normally or is more perceived by the user according to the preset conversion ratio. For example, the preset conversion ratio may be 70%.
Further, determining a corresponding color disorder mode according to the preset conversion ratio and the color vision disorder degree includes: determining a color conversion matrix according to a preset conversion proportion and the color vision disorder degree; generating the color barrier pattern according to the color conversion matrix.
It should be noted that the color barrier pattern is a color conversion strategy generated according to a color conversion matrix, and a picture with the best viewing effect for a user can be obtained by converting an image to be converted according to the color conversion strategy.
It is understood that different color conversion matrices may be generated for converting colors according to different degrees of dyschromatopsia and preset conversion ratios.
Further, the color conversion matrix includes: at least one of a red conversion matrix, a green conversion matrix, and a blue conversion matrix;
Figure BDA0002869876670000071
Figure BDA0002869876670000072
Figure BDA0002869876670000073
wherein, TCRFor a red conversion matrix, TCGAs a green conversion matrix, TCBThe color conversion matrix is blue, gamma is a preset conversion ratio, and alpha R, alpha G and alpha B are the color vision disorder degrees of the corresponding colors respectively.
In concrete embodimentsNow, for example, a user with red color blindness cannot perceive the color of the red color system, and the color obstacle mode includes the color perceivable by the user with red color blindness and the color imperceptible, at this time, 70% of the color of the red color system may be converted into other colors, that is, 70% of the color of the L channel in the LMS color space is converted into the M channel and the S channel, and then the preset conversion ratio of 70% is taken as an example, and the red conversion matrix T is a red conversion matrix TCRCan be as follows:
Figure BDA0002869876670000074
step S40: and determining the color to be converted in the image to be converted according to the color barrier mode.
Further, step S40 includes: acquiring an image to be converted; converting the original color of the RGB color space in the image into the space color of the LMS color space; and determining the color to be converted in the image to be converted according to the space color and the color barrier mode.
It should be noted that, when the original image, that is, the image to be converted, is obtained, the color of the original image needs to be converted from the RGB color space to the LMS color space, and the color that cannot be perceived by the user in the image to be converted, that is, the color to be converted, is obtained from the color of the LMS color space.
It should be noted that there are 3 kinds of cones in human eye, which have different spectral sensitivities, and these three kinds of cones are respectively called as: short (S), medium (M), and long (L) cone cell types. S, M and L-class cones normalized response spectra to monochromatic spectral stimuli are shown in FIG. 3. Since the physiological causes of color blindness and color weakness are related to the absence or defect of LMS three cells, the current color space is first transferred to the LMS space. Since the physiological causes of color blindness and color weakness are related to the absence or defect of LMS three cells, the current color space is first transferred to the LMS space. If the current picture is inputted with a commonly used RGB color space, it needs to be transferred to an LMS space first, and knowing that the conversion matrix from the RGB space to the LMS space is X, LMS × RGB, and the matrix X is the prior art, which is not described herein.
In a specific implementation, the color perceivable by the user can be recognized through the color barrier mode, the image is denoted as Lp Mp Sp, and the color which cannot be perceived by the user is: LEp MEp SEp ═ LMS-Lp Mp Sp. The color which cannot be perceived by the user in the image to be converted, namely the color to be converted, can be obtained through the above formula. For example: the user with the color blindness cannot perceive the color of the green system, the color obstacle mode of the user identifies the colors of other color systems in the image to obtain the color of the green system, and at the moment, the color of the green system in the image is the color to be converted.
Step S50: and converting the color to be converted into a corresponding color to obtain the target color of the image to be converted.
In a specific implementation, colors that cannot be perceived by users with dyschromatopsia are mapped into the color gamut that they can see through the color conversion matrix Tc to obtain target colors, for example: dispersing 70% of L channel colors which cannot be seen by a red dyschromatosis person into an M channel, dispersing 70% of L channel colors into an S channel, and converting a corresponding red dyschromatosis conversion matrix into:
Figure BDA0002869876670000081
the corrected color is denoted as LSEp MSEp SSEp, i.e., LSEp MSEp SSEp ═ Tc × LEp MEp SEp.
Further, after step S50, the method further includes:
and converting the target color in the image to be converted into the color of the RGB color space to obtain the corrected color.
It can be understood that the LMS gamut space is converted to the original RGB gamut space, the conversion matrix from the LMS space to RGB is denoted as X ', the converted matrix is denoted as R ' G ' B ', and then R ' G ' B ═ X ' LSEp MSEp SSEp.
And superposing the corrected color and the original color of the image to be converted to obtain a target image.
Note that R 'G' B 'is superimposed on the RGB original image to obtain an optimized picture, that is, RcGcBc is RGB + R' G 'B'. When users with color vision disorder watch the picture, the color information which cannot be perceived by the users can be distinguished.
The sorting flow chart is as shown in fig. 4, the color of the original image is converted from the RGB color space to the LMS color space, the color perceivable by the user is obtained according to the user selection, the color not perceivable by the user in the original image is obtained, the color not perceivable by the user is converted to the color gamut perceivable by the user, the converted color is converted to the RGB color space and is overlapped with the original image, and the modified image is obtained.
The embodiment sets the instruction by obtaining the perception of the user; determining the color vision disorder degree of the user according to the perception setting instruction; determining a corresponding color disorder mode according to the color vision disorder degree; determining the color to be converted in the image to be converted according to the color barrier mode; converting the color to be converted into a corresponding color to obtain a target color of the image to be converted; converting the target color in the image to be converted into the color of an RGB color space to obtain a corrected color; and superposing the corrected color and the original color of the image to be converted to obtain a target image. By the mode, the corresponding color obstacle mode can be determined according to different color vision obstacle conditions of different users, colors which cannot be sensed by the users are converted into pictures with the best user appearance according to the color obstacle mode, all colors of the pictures can be distinguished by the users through the customized color conversion scheme, the scene resolution capability of the users is improved, and the user experience is greatly improved.
