[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application. In addition, unless otherwise specified (for example, "or in addition" or "or in an alternative"), the term "or" as used herein refers to a non-exclusive "or" (that is, "and / or"). Moreover, the various embodiments described herein are not necessarily mutually exclusive, because some embodiments can be combined with one or more other embodiments to form new embodiments.
[0021] This application proposes a map screen processing method. Figure 1As shown, the map screen processing method of the present application includes the following steps. Optionally, the map screen processing method of the present application can be applied to a screen processing device. Among them, the screen processing device can be a mobile phone, a computer, a car navigation and other devices, which are not specifically limited here. It should be noted that the following step numbers are only used to simplify the description and are not intended to limit the execution order of the steps. The execution order of each step of this embodiment can be changed arbitrarily without violating the technical ideas of the present application.
[0022] S101: Obtain a map image to be processed.
[0023] The map screen to be processed can be obtained first, so that the focus color in the map screen to be processed can be highlighted later to obtain a highlighted screen, so that the information presented by the focus color in the screen can be highlighted when the screen is displayed, so that the user can intuitively and quickly obtain important information on the video or image.
[0024] The method of obtaining the map picture to be processed is not limited. Specifically, the map picture to be processed can be obtained by shooting with a camera, or the map picture to be processed can be obtained from other devices such as a server. Exemplarily, the map picture to be processed can be a navigation picture obtained from a server.
[0025] S102: Highlighting the concerned color in the map picture to be processed to obtain a highlighted picture.
[0026] After the map screen to be processed is obtained, the focus color in the map screen to be processed may be highlighted to obtain a highlighted screen.
[0027] The attention color may be the display color of important information in the map screen to be processed, that is, the display color of the information that the user pays special attention to in the map screen to be processed.
[0028] Optionally, the focus color may be determined according to the usage scenario of the map image to be processed. For example, if the usage scenario is a vehicle navigation scenario, the focus colors may include: yellow for displaying lane planning information, blue, red and green for displaying signboards, and / or green, yellow and red for displaying road conditions.
[0029] In one achievable manner, the step of highlighting the focus color in the map picture to be processed may include: increasing the saturation and / or brightness of the focus color in the map picture to be processed.
[0030] In another achievable method, the step of highlighting the focus color in the map screen to be processed may include: reducing the saturation and / or brightness of colors other than the focus color in the map screen to be processed, so that the saturation and / or brightness of the focus color is relatively improved, thereby highlighting the focus color in the map screen to be processed.
[0031] Among them, the color processing unit can perform highlighting processing on the focus color in the map picture to be processed to obtain a highlighted picture.
[0032] In addition, after the highlighted image is obtained based on step S102, the highlighted image can be displayed so that the user can quickly obtain important information on the video or image through the displayed image. In one embodiment, the highlighted image can be sent to the display control unit, so that the highlighted image is sent to the display unit for display through the display control unit. In another embodiment, the highlighted image can be sent to another device so that the other device can display the highlighted image.
[0033] In this embodiment, a map screen to be processed is obtained, and then the focus color in the map screen to be processed is highlighted to obtain a highlighted screen, so that the focus color in the screen can be highlighted when the screen is displayed, thereby facilitating users to intuitively and quickly obtain important information on the video or image.
[0034] This application proposes another map screen processing method. Figure 2 As shown, the map screen processing method of the present application includes the following steps. It should be noted that the following step numbers are only used to simplify the description and are not intended to limit the execution order of the steps. The execution order of each step of this embodiment can be changed arbitrarily without violating the technical idea of the present application.
[0035] S201: Obtain the map image to be processed.
[0036] S202: increasing the saturation and / or brightness of the focus color in the map picture to be processed to obtain a highlighted picture.
[0037] In one implementation, the saturation of the concerned color in the map screen to be processed can be uniformly increased by a first value, and / or the brightness of the concerned color in the map screen to be processed can be uniformly increased by a second value. The first value and the second value can be set according to actual conditions and are not limited here.
[0038] For example, the saturation and brightness of the focus color in the map picture to be processed are uniformly increased, and the global saturation of the map picture to be processed is overall increased.
[0039] In another implementation, the saturation and / or brightness of the color of interest in the map screen to be processed can be increased based on the adaptability of the ambient brightness. Preferably, the ambient brightness is a positive factor that affects the amount of increase in the saturation and / or brightness of the color of interest. More preferably, the amount of increase in the saturation and / or brightness of the color of interest is positively correlated with the current ambient brightness, that is, the higher the ambient brightness, the higher the amount of increase in the saturation and / or brightness of the color of interest, so that the saturation and / or brightness of the color of interest is adaptively increased according to the ambient brightness to enhance the highlighting effect of the color of interest.
[0040] The ambient brightness may be detected in real time by an ambient brightness detection unit in the image processing device.
[0041] In yet another implementation, the map screen to be processed may be analyzed to obtain an analysis result of the map screen to be processed; based on the analysis result, the saturation and / or brightness of each focus color may be increased.
[0042] That is, the distribution of each focus color in the map screen to be processed can be analyzed, and the saturation and / or brightness of the focus color in the map screen to be processed can be improved based on the distribution of each focus color. For example, it can be analyzed whether each focus color appears in the map screen to be processed, and the saturation and / or brightness of the focus color appearing in the map screen to be processed can be improved.
[0043] Optionally, the distribution amount of each focus color in the map picture to be processed may be analyzed, and the brightness and / or saturation of each focus color in the map picture to be processed may be increased based on the distribution amount of each focus color in the map picture to be processed.
[0044] Specifically, the amount of increase in saturation and / or brightness of each focus color may be determined based on the distribution amount of each focus color in the map picture to be processed.
[0045] Preferably, the distribution amount of the attention color is a positive factor affecting the increase in saturation and / or brightness of the attention color, that is, the increase in saturation and / or brightness of the attention color with a large distribution amount is higher than or equal to the increase in saturation and / or brightness of the attention color with a small distribution amount, so that the information presented by the attention color with a large amount in the screen can be further highlighted. Furthermore, the distribution amount of the attention color can be positively correlated with the increase in saturation and / or brightness of the attention color.
[0046] Of course, in other embodiments, the distribution amount of the attention color is a negative factor that affects the increase in the saturation and / or brightness of the attention color, that is, the increase in the saturation and / or brightness of the attention color with a large distribution amount is lower than or equal to the increase in the saturation and / or brightness of the attention color with a small distribution amount, so that the information corresponding to the attention color with a small amount in the display screen can be further highlighted, so that the user can not only quickly obtain the information corresponding to the attention color with a large amount, but also quickly obtain the information corresponding to the attention color with a small amount based on the greatly improved saturation and / or brightness, so as to facilitate the user to quickly obtain important information corresponding to various attention colors. Further, the distribution amount of the attention color can be negatively correlated with the increase in the saturation and / or brightness of the attention color.
[0047] Optionally, a histogram of at least one of the Y channel, R channel, G channel, B channel, H channel, S channel and V channel of the map picture to be processed may be analyzed to obtain an analysis result of the map picture to be processed.
[0048] For example, the map image to be processed can be analyzed as follows: Figure 3 The color histogram of the HSV space shown in Figure 4 The histogram of the H channel of the map picture to be processed is shown to determine the distribution amount of each focus color in the map picture to be processed. Specifically, the proportion of different colors in the entire picture can be determined through the histogram of the H channel of the map picture to be processed, thereby determining the distribution amount of each focus color in the map picture to be processed.
[0049] Of course, in some embodiments, the color histogram of the Luv space or the color histogram of the Lab space may also be analyzed to determine the distribution of each focus color in the map image to be processed.
[0050] Optionally, the map picture to be processed may be analyzed by an image processing unit, for example, by using special hardware, a CPU or a GPU.
[0051] In another implementation, in response to a change in ambient brightness, the saturation and / or brightness of the map screen to be processed may be uniformly adjusted based on the current ambient brightness to obtain a first adjustment screen; then the saturation and / or brightness of the focus color in the first adjustment screen may be increased to obtain a highlighted screen. In another embodiment, the saturation and / or brightness of other colors in the first adjustment screen except the focus color may be reduced to highlight the focus color in the first adjustment screen to obtain a highlighted screen.
[0052] S203: Display the highlighted image.
[0053] In addition, based on the current usage scenario of the screen processing device, it can be determined whether it is necessary to use the map screen processing method of the above embodiment to highlight the map screen to be processed.
[0054] For example, in response to the current usage scenario of the image processing device being a map navigation scenario, the map image processing method of the above embodiment can be used to highlight the map image to be processed. Figure 5 As shown, the map screen processing method of the above embodiment can be used to Figure 5 The map screen to be processed is highlighted and obtained Figure 6 The highlighted screen shown in the figure. The focus colors, namely the red color indicating the road condition and the yellow color indicating the route, have been enhanced so that users can more easily notice the navigation information and changes in road conditions.
[0055] Alternatively, in response to the current usage scenario of the image processing device being an image color enhancement scenario and the color to be enhanced being set, the color to be enhanced can be used as a focus color, and the map image processing method of the above-mentioned embodiment can be used to highlight the map image to be processed.
[0056] Optionally, the current usage scenario of the image processing device can be determined based on the application currently used by the image processing device and its running function. Of course, in some embodiments, AI can also be used to analyze the map image to be processed to determine the current usage scenario of the image processing device. In addition, AI can be used to analyze user preferences and decide whether to enable the map image highlighting function based on the historical usage data of different users.
[0057] In addition, in some embodiments, no matter what the current usage scenario is, the map screen processing method of the above-mentioned implementation can be used to highlight the map screen to be processed.
