Description

Technical Field

[0001] The present application relates to the field of color gamut control, and in particular to a method, device, equipment and medium for controlling the color gamut of a small-pitch LED display screen. Background Art

[0002] "Color gamut" is a method of encoding a color, and also refers to the sum of colors that a technical system can produce. The color gamut of a display refers to the richness of colors that the display can display. With the development of people's visual requirements, different color gamut standards have emerged for displays used in different scenarios. The mainstream color gamut standards are sRGB, NTSC, DCI-P3, and Adobe RGB. Generally speaking, these color gamut standards can already meet the needs of various industries, but if videos or pictures that originally belong to different color gamut standards appear on a display manufactured according to a fixed color gamut standard, color distortion will occur.

[0003] The current market solution to the problem of color distortion on displays is usually to manually adjust the color gamut standard applicable to the display to highly restore the original effect. However, non-professionals will not be able to reasonably adjust the color gamut standard applicable to the display according to their own needs, which means that they will not be able to achieve the best effect that the display can present.

[0093] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0094] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0095] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0096] The embodiment of the present application provides a method for adjusting the color gamut of a small-pitch LED display screen, which is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method may include:

[0097] Step A001, obtain user information.

[0098] Step A002, comparing the user information with the preset color gamut preference standard to obtain the user preference.

[0099] The user information includes the user's physical features.

[0100] For the embodiment of the present application, the facial image of the user is acquired through the acquisition device, and the acquired facial image is located and identified to obtain the physical features of different users. The historical color gamut preferences are screened according to the physical features to obtain the color gamut standard with the highest proportion in the historical color gamut preferences. The color gamut standard with the highest proportion and the user position are input into the BP neural network model to obtain the user's color gamut preference. The user's color gamut preference is matched with the preset color gamut preference standard. When the matching degree is 1, it is determined that the match is successful, and the user preference is generated according to the preset color gamut preference standard.

[0101] Specifically, the method used to generate the user preference according to the preset color gamut preference standard includes but is not limited to: a summary generation algorithm.

[0102] Step A003, obtaining prompt information based on user preference.

[0103] Step A004, obtaining the user-specified effect according to the prompt information.

[0104] The prompt information is used to indicate the display effect prompt information for the user, and the user-specified effect is used to indicate the user's actual preference for the display effect.

[0105] For the embodiment of the present application, the user preference is used as prompt information, and the prompt information selected by the user is obtained, and the prompt information selected by the user is used as the user-specified effect.

[0106] For example, the user preferences are:

[0107] A: Color space / color gamut for professional office use;

[0108] B: Color space / color gamut range used for daily movie watching.

[0109] At this time, the prompt information is consistent with the user's preference, and the prompt information is controlled to be displayed, and the user-specified effect is obtained by performing voice recognition / expression recognition on the user within a fixed time limit. If the duration after the prompt information is controlled to be displayed exceeds the fixed time limit, the user-specified effect with the highest proportion in the current user's historical viewing record is determined to be the user-specified effect at this time; if the voice recognition detects that the current user's semantics is "professional office" / "A", the prompt information selected by the user is determined to be A, that is, the user-specified effect is A; if the expression recognition detects that the current user's eyes are inclined to the display position of A, the prompt information selected by the user is determined to be A, that is, the user-specified effect is A.

[0110] Step A005, perform color control adjustment according to the effect specified by the user.

[0111] For the embodiment of the present application, the current color gamut is changed to the color gamut included in the user-specified effect.

[0112] The present application provides a method for adjusting the color gamut of a small-pitch LED display screen, which obtains a user image through an acquisition device, performs feature analysis on the user image to obtain user information, compares the user information with a preset color gamut preference standard, and obtains the user's color gamut preference, that is, the user preference. After that, the user preference is analyzed for display effects to obtain prompt information, and the user-specified effect is obtained in the prompt information of the display effect, and color control is adjusted according to the user-specified effect until the user-specified effect is displayed, thereby achieving the effect of adjusting the color gamut according to the display requirements of different users.

[0113] In a possible implementation of the embodiment of the present application, step A002 includes step A006 (not shown in the figure), step A007 (not shown in the figure), step A008 (not shown in the figure) and step A009 (not shown in the figure), wherein:

[0114] Step A006, obtaining user preference factors and user location based on user information.

[0115] Step A007, input the user preference factors and the user position into the trained neural network algorithm to obtain the user color gamut preference.

[0116] Among them, the user information includes: facial features; the user preference factors include: the user's corresponding historical color gamut standard.

[0117] For the embodiment of the present application, facial features are extracted from the face detected in the user image, and user features are obtained based on the facial features. Thereafter, the historically used color gamut standards are screened using different user features to obtain the historically used color gamut standards corresponding to different user features, that is, the user preference factors.

[0118] The two eyes of the user's face in the user image are located and the distance between the two eyes is obtained. The user distance is obtained through similar triangles and the actual human eye distance.

[0119] A coordinate system is established with the middle position in the user image as the coordinate origin, the distance between the user and the coordinate origin is obtained through the obtained user distance, and the user position is determined according to the distance between the user and the coordinate origin and the user distance.

[0120] For example, if the extracted facial features are: the user has wrinkles on his face, then the user is 30-50 years old; if the extracted facial features are that the wrinkles on the user's face are distributed over 70% of the area, then the user is 50-70 years old. At this time, according to the different ages of the users, the historical color gamut standards are screened to obtain the historical color gamut standards corresponding to different ages. The screening results are as follows:

[0121] Age 30-50: 80% of the historical color gamut standard is 100% NTSC, and 20% of the historical color gamut standard is 100% sRGB;

[0122] Age 50-70: 80% of the people use the sRGB color gamut standard of 100%, and 20% of the people use the NTSC color gamut standard of 100%.

[0123] The historically used color gamut standard with the highest proportion is used as the user preference factor for the corresponding user characteristics, and the user preference corresponding to the user characteristics of the age of 30-50 is 100% NTSC, and the user preference corresponding to the user characteristics of the age of 50-70 is 100% sRGB.

[0124] The embodiment of the present application uses a BP neural network to determine the user's color gamut preference. When building the BP neural network algorithm, the historical color gamut standard and the user's position are used as the two input nodes of the artificial neural network input layer, 10 neurons are selected as the hidden layer, the Sigmoid type excitation function (used for the hidden layer neuron output) is used as the excitation function, and the user's color gamut preference is used as the output of the output layer.

[0125] Several historically used color gamut standards, several user positions, and several user color gamut preferences are used as training samples. When the output result is the same as the actual user color gamut preference, the model training is deemed successful. At this time, the historically used color gamut standards and user positions obtained in the embodiment of the present application are input into the successfully trained neural network model to obtain the user color gamut preference corresponding to the user information.

[0126] For example, if there are user A, user B, and user C,

[0127] User A’s user position is 3m in front, and the historical color gamut standard is 100% sRGB;

[0128] User B's user position is 8m to the left and front, and the historically used color gamut standard is 100% NTSC;

[0129] User C’s user position is 10m to the right and the historical color gamut standard used is 100% Adobe RGB;

[0130] Then user A's color gamut preference is: 100% sRGB + 90% daily brightness;

[0131] User B's color gamut preference is: 100% NTSC + 130% daily brightness;

[0132] User C's color gamut preference is: 100% Adobe RGB + 150% daily brightness.

[0133] If the user position of user A is 3m in front, the historical color gamut standard is 100% sRGB;

[0134] User B’s user position is 3m to the left and front, and the historically used color gamut standard is 100% NTSC;

[0135] The user position of user C is 4m to the right and the historical color gamut standard is 100% Adobe RGB;

[0136] Then user A's color gamut preference is: 100% sRGB + 90% daily brightness;

[0137] User B's color gamut preference is: 100% NTSC + 100% daily brightness;

[0138] User C's color gamut preference is: 100% Adobe RGB + 100% daily brightness.

[0139] Step A008, comparing the user color gamut preference with the preset color gamut preference standard to obtain the preset user preference.

[0140] Step A009: Generate a preference description according to the preset user preference, and bind the preset user preference and the preference description to obtain the user preference.

[0141] The preset color gamut preference standard is the corresponding relationship between the user's color gamut preference and the display effect.

[0142] For the embodiment of the present application, the user color gamut preference is matched with the preset color gamut preference standard. If the matching degree is 1, it is determined that the match is successful at this time, and the display effect is used as the preset user preference.

[0143] Generate a preference description based on the display effect, and bind the display effect and the preference description as the user preference. For example, if the display effect has high color reproduction and bright colors, which is suitable for professional office use, then a preference description is generated through a summary generation algorithm, namely, professional form / office mode / color-intensive stimulation mode.

[0144] Specifically, the method of generating the preference description through display effects and the generated results should be selected according to actual conditions, including but not limited to the one introduced in the embodiment of the present application.

[0145] In a possible implementation of the embodiment of the present application, step A006 further includes step A010 (not shown in the figure), step A011 (not shown in the figure), step A012 (not shown in the figure) and step A013 (not shown in the figure), wherein:

[0146] Step A010, obtaining the number of users based on the user information, and if the number of users is greater than a preset value, generating a primary user locking instruction and controlling the execution of the primary user locking instruction.

[0147] Step A011, obtain the current display content, compare and analyze the current display content and user information, and obtain main user information.

[0148] Among them, the preset value is: value 1; the main user locking instruction is used to indicate that the main user information is obtained by analyzing the user and the currently displayed content; the main user information is used to indicate the user information that pays the most attention to the currently displayed content among the user information.

[0149] For the embodiment of the present application, it is determined whether the number of faces detected in the currently collected user image is greater than 1. If the judgment result is greater than 1, it is determined that there are multiple users at this time, and the current display content is obtained. The type analysis of the current display content is performed to obtain the current content type (for example: children, animation). At the same time, according to different user characteristics, the viewing type with the highest proportion in the user's viewing history is locked (for example: user A-children, animation; user B-teenagers, hot-blooded; user C-war, science fiction).

[0150] The current content type is compared with the viewing type, and the type with the highest similarity between the two and the user corresponding to the type are screened out, and the user is taken as the main user, and the corresponding physical characteristics of the user are taken as the main user information.

[0151] Step A012, attaching a priority display tag to the main user information to obtain the superior user information.

[0152] Step A013, taking the superior user information and the user information other than the main user information as the updated user information.

[0153] Among them, the priority display label indicates that the user preferences obtained by analyzing the main user information need to be displayed first.

[0154] For the embodiment of the present application, a priority display tag is added to the main user, and the result after the addition is used as the superior user information. The user information containing multiple users is filtered out to obtain the remaining user information except the main user, and the superior user information and the remaining user information are used as the user information.

[0155] A possible implementation of the embodiment of the present application further includes step A014 (not shown in the figure), step A015 (not shown in the figure), step A016 (not shown in the figure), step A017 (not shown in the figure), step A018 (not shown in the figure) and step A019 (not shown in the figure), wherein:

[0156] Step A014, obtaining the current color gamut standard.

[0157] Step A015, performing applicable color gamut analysis on the current display content to obtain the current content color gamut.

[0158] Step A016, matching the current content color gamut with the current color gamut standard. If the match is successful, changing the current color gamut standard to the applicable color gamut standard, and controlling the display of the applicable color gamut standard.

[0159] Step A017: If the match fails, the user's color gamut preference is compared with the current content color gamut to analyze the visual effect and obtain a visual difference value.

[0160] Among them, the current color gamut standard is the color gamut possessed by the display device; the current content color gamut is used to represent the standard color gamut of the currently displayed content; the applicable color gamut standard is the color gamut standard actually adopted by the display device; the visual difference value is used to represent the difference in visual effects between the display effect of the current content and the standard display effect.

[0161] For the embodiment of the present application, the current color gamut standard is obtained, and then the current display content is converted into continuous video frames, and the pixel points of several video frames are divided to obtain the colors corresponding to the pixel points, and finally the colors are summarized to obtain the applicable color gamut of the current content. The current color gamut standard is matched with the applicable color gamut of the current content. If the matching degree is 1, the match is deemed to be successful, and the current color gamut standard is applied as the applicable color gamut standard; if the matching degree is not 1, the match is deemed to have failed, and the visual experience effect of the user when the color gamut preference is applied to continuous video frames is obtained, and the visual experience effect obtained at this time is compared with the visual experience effect corresponding to the original display content, and the comparison result is used as the visual difference value.

[0162] Step A018, bind the user's color gamut preference with the visual difference value to obtain an effect prompt.

[0163] Step A019, controlling the display effect prompt.

[0164] For the embodiment of the present application, the visual difference value is bound to the color gamut standard in the user color gamut preference, and the binding result is used as an effect prompt to control the display. For example, if the color gamut standard in the user color gamut standard is 100% NTSC, and the visual difference value is: oversaturation, then the effect prompt (displayed) at this time is: 100% NTSC-oversaturation.

[0165] In a possible implementation of the embodiment of the present application, step A017 includes step A020 ​​(not shown in the figure) and step A021 (not shown in the figure), wherein:

[0166] Step A020, input the user's color gamut preference and the current display content into the trained neural network algorithm to obtain the current display effect.

[0167] Step A021, compare and analyze the current display effect with the preset standard effect to obtain a visual difference value.

[0168] The current display effect is used to indicate the visual effect that the current display content can display within the current color gamut standard.

[0169] For the embodiment of the present application, the currently displayed content is converted into a continuous video frame input to obtain the color gamut in the user's color gamut preference, and the visual experience effect is obtained. The obtained visual experience effect is compared with the standard visual experience effect corresponding to the currently displayed content, and the comparison result is used as the visual difference value.

[0170] The embodiment of the present application also uses a BP neural network to obtain the visual effects of users with different color gamut preferences. The process of training the BP neural network algorithm is the same as that in step A007. Different preference weights are set according to different user color gamut preferences, and several video frames of the current content are used as input, and the visual effects corresponding to different user color gamut preferences are used as output.

[0171] For example, if the user's color gamut preference is 100% sRGB + 80% daily light, then because the user's color gamut preference has lower requirements for daily light and higher requirements for color gamut, the light sensitivity weight can be set to 30% and the color contrast weight can be set to 70%.

[0172] Subtract the output visual effect from the standard visual experience effect (100% restoration effect), and use the difference as the visual difference value.

[0173] In a possible implementation of the embodiment of the present application, step A018 further includes step A022 (not shown in the figure) and step A023 (not shown in the figure), wherein:

[0174] Step A022, performing a visual safety analysis on the display effect of the current display content, and if the analysis result is dangerous, generating an instruction to control the display content.

[0175] The control display content instruction is used to indicate that the current display content is in a playing state and the playing is stopped.

[0176] For the embodiment of the present application, the current display content is respectively applied to the current color gamut standard and the display effect is obtained, and it is determined whether there is a situation that causes visual damage to the current user in different display effects. If so, it is determined that the display effect at this time is in a dangerous state, and the current display content is controlled to stop displaying one second before the dangerous state occurs. For example, the current display content is a 30-minute video. At 15 minutes and 3 seconds into the video playback, due to the mismatch between the current color gamut standard and the color gamut of the current display content, there is too much white light on the screen, that is, the brightness exceeds the maximum range that the current user can accept, and the 15 minutes and 3 seconds are determined to be a dangerous state.

[0177] Step A023, bind the analysis result and the display effect to obtain warning information.

[0178] For the embodiment of the present application, the dangerous state and the display effect corresponding to the dangerous state are bound and the binding result is used as the warning information. For example, if the display effect at 15 minutes and 3 seconds in the video is too bright and there is a dangerous state, the generated warning information is: 15:03-Brightness is too high-danger.

[0179] In a possible implementation manner of the embodiment of the present application, step A004 further includes step A024 (not shown in the figure), step A025 (not shown in the figure), step A026 (not shown in the figure), step A027 (not shown in the figure), step A028 (not shown in the figure) and step A029 (not shown in the figure), wherein:

[0180] Step A024, obtaining the current display spacing.

[0181] Step A025, restore the distance of the user's position according to the acquisition ratio to obtain the user's optimal viewing distance.

[0182] Step A026, performing display spacing analysis on the optimal viewing distance to obtain the optimal display spacing.

[0183] Step A027, performing a multiple analysis of the current display spacing and the optimal display spacing to obtain the optimal multiple.

[0184] Step A028, adjusting the current display spacing according to the optimum multiple to obtain the optimum display spacing.

[0185] Step A029, controlling the display of the current display content according to the optimal display spacing.

[0186] The acquisition ratio is the ratio of the focal length to the user distance; the current display spacing is used to indicate the spacing of the current minimum display unit.

[0187] For the embodiment of the present application, the minimum display unit spacing of the current display device is obtained, and the user distance is obtained by the same method as step A006, and the user distance is used as the user's optimal viewing distance. The user's optimal viewing distance is input into the calculation formula of the minimum display unit spacing and the optimal viewing distance (minimum display unit spacing * 3000 - minimum display unit spacing * 1000) to obtain the optimal display spacing.

[0188] The optimal display spacing and the minimum display unit spacing are analyzed by ratio to obtain the optimal multiple. The minimum display unit spacing is adjusted according to the optimal multiple to obtain the optimal display spacing for the current user distance. A certain minimum display unit and its surrounding minimum display units are taken as the same display unit. When the same display unit spacing is equal to the optimal display spacing, the current display content is displayed according to the display spacing at this time.

[0189] In summary, by analyzing the user's historical color gamut selection and user characteristics, the user is assisted in adjusting the color gamut, thereby achieving the most suitable display effect for different users.
