The present disclosure solves the problem of the prior art that a functional icon cannot be recognized by a user when the colors of the background picture and the functional icon are consistent, improves the display visibility of the icon.

TECHNICAL FIELD

The embodiments of the present disclosure relate to the field of electronic technology, and, more particularly, to a display method and a display device.

BACKGROUND

With the gradually increasing image processing ability of an intelligent terminal in hardware aspect, and more and more higher requirements of users on the user interface (English: User Interface; abbreviation: UI) display ability of the intelligent terminal, more display effects are added into a display application of the intelligent terminal. For example: the users are allowed to change desktop background pictures of the intelligent terminal according to the hobbies thereof.

However, the UI of the intelligent terminal includes at least two display layers: a first display layer and a second display layer. Wherein, the first display layer is used for displaying the desktop background pictures set by the users; therefore, the first display layer may also be called as a background display layer.FIG. 1(a)is a background picture configured by a system, and the background picture of the intelligent terminal may be a picture having a single-color, for example: a blue picture or a black picture, etc. The background picture may also be a picture that includes specific contents. The second display layer is used for displaying various icons configured by the system, as shown inFIG. 1(b), for example: a time icon, an alarm clock icon, an APP icon, etc.

During practical application, the second display layer is generally divided into two display areas: a first display area and a second display area. Wherein, the first display area is used for displaying general icons configured by the system, for example: a time icon, a signal strength icon, an electric quantity icon, an alarm clock icon, or the like. These icons are relatively fixed; therefore, the first display area may also be called as a notification bar display area. The second display area is used for displaying the APP icons of APPs installed on the intelligent terminal. These icons are relatively flexible; therefore, the second display area may also be called as an application display area.

The at least two display layers included in the UI are displayed in an overlapping manner. Generally, the second display layer may also be called as a transparent layer. When designing the display of the UI, the second display layer is usually located above the first display layer; in this way, when viewing various icons displayed in the second display layer, the background picture displayed in the first display layer may also be seen through the second display layer, i.e., the user interface configured by the system as shown inFIG. 1(c).

It is found by the inventor during the process of implementing the present disclosure that: During practical application, because the colors of various icons of the second display layer are pre-configured by the system, which are relatively fixed, once the user determines the background picture displayed in the first display layer, when the color of the background picture displayed in the first display layer determined is closer to the color of the icon displayed in the second display layer, the user cannot recognize the icon displayed in the second display layer, which reduces the efficiency of the user for viewing the icon displayed in the second display layer, and brings inconvenience when the user is using the intelligent terminal.

For example:FIG. 1(d)shows a user interface that the user participates in configuration. It may be seen fromFIG. 1(d)that theFIG. 1(c)differs fromFIG. 1(d)in the background picture; moreover, the contents of circled parts in the figures can been seen inFIG. 1(c), but cannot be recognized inFIG. 1(d).

DETAILED DESCRIPTION

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clearly, the technical solutions of the present disclosure will be clearly and completely described hereinafter with reference to the embodiments and drawings of the present disclosure. Apparently, the embodiments described are merely partial embodiments of the present disclosure, rather than all embodiments. Other embodiments derived by those having ordinary skills in the art on the basis of the embodiments of the present disclosure without going through creative efforts shall all fall within the protection scope of the present disclosure.

The embodiments of the present disclosure provide a display method and a display device which receive a picture sent by a user for being displayed in a first display layer; perform display overlapping on the picture and a second display layer including icons; when the color contrast of the icon in a first area of the second display layer being overlapped onto the picture displayed in the first area of the first display layer is less than a first preset threshold, adjust the color contrast in the first area, so that the adjusted color contrast is greater than a second preset threshold, the second threshold being greater than or equal to the first threshold; and display the first display layer including the pictures and the second display layer including the icons into a user interface UI in an overlapping manner according to the adjustment result. In this way, for the same display area, when the color of the picture displayed in the first display layer and the color of the icon displayed in the second display layer are consistent, the color of the picture and/or the color of the icon is adjusted flexibly, so that the color contrast between the color of the picture and the color of the icon is increased, the display visibility of the icon is improved, the problem that the icon cannot be recognized by the user when the color of the picture displayed in the first display layer is consistent with the color of the icon displayed in the second display layer is solved, and the flexibility of the user for operating the intelligent terminal is increased.

It should be noted that the color contrast described in the embodiments of the present application refer to the degree of closeness between different colors. An RGB (i.e., red, green and blue) manner is adopted for representing colors usually. When judging the degree of closeness between different colors, it is desirable to convert the RGB manner into an HSB/HSV manner. Wherein, the HSB/HSV manner mainly includes: hues (hues), saturation (saturation) and brightness (brightness/value).

That is, the colors are represented through the three elements including hues/saturation/brightness. Wherein, the hues represent the type of the color (for example: red, green or yellow), having a value range of 0˜360 degrees, and each value represents one color; the saturation represents the purity of the color, having a value range of 0˜1; and the brightness represents the degree of brightness of the color, having a value range of 0˜1.

It may be found through an HSB/HSV color space model that the hues, saturation and brightness of the color are linearly changed visually, then the color contrast between different colors may be determined by setting thresholds for the hues, saturation and brightness. If all the hues, saturation and brightness of two different colors satisfy the preset thresholds, then the color contrast of the two colors may be deemed to be closer mutually.

For example: it is provided that the set threshold of the hues is ±5, the set threshold of the saturation is ±0.2, the set threshold of the brightness is ±0.2, the hue of a color 1 is 1, the saturation of the color 1 is 0.1, and the brightness of the color 1 is 0.1; the hue of a color 2 is 3, the saturation of the color 2 is 0.05, and the brightness of the color 2 is 0.05, then through comparison, it is determined that the color contrast of the color 1 and the color contrast of the color 2 are closer to each other.

Further illustrative explanations will be made clearly and completely to the technical solutions in various embodiments of the disclosure hereinafter with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the embodiments described are merely partial embodiments of the present disclosure, rather than all embodiments. Other embodiments derived by those having ordinary skills in the art on the basis of the embodiments of the present disclosure without going through creative efforts shall all fall within the protection scope of the present disclosure.

FIG. 2is a schematic diagram illustrating a flow of a display method provided by the embodiment of the present disclosure. The method may be described as follows. An executive body of the embodiment of the present disclosure may either be a graphic processing unit (English: Graphic Processing Unit; abbreviation: GPU) in an intelligent terminal, or the intelligent terminal, which will not be defined herein.

In step201: a picture sent by a user for being displayed in a first display layer is received.

In step201, when a user needs to change the picture displayed in the first display layer, a picture needing to be changed is sent to a graphic processing unit through a display system of an intelligent terminal, so that the graphic processing unit receives the picture for being displayed in the first display layer.

For example: when the user opens the intelligent terminal and determines that a desktop background picture needs to be changed (i.e., the picture displayed in the first display layer), the user enters a desktop background management system (i.e., a display management system) at this moment, changes the desktop background picture, and triggers a “Confirm” or “Apply” button; at this moment, the graphic processing unit receives the picture sent by the user for being displayed in a desktop background display layer (i.e., the first display layer).

It should be herein noted that that the user may select other attributes while changing the desktop background picture, for example: a display mode of the picture, and a display resolution of the picture, or the like; and may also select an intelligent mixed attribute, and the intelligent mixed attribute herein refers to subsequent operations recorded in the embodiment of the present disclosure.

That is, when the graphic processing unit receives the picture sent by the user for being displayed in the first display layer, it is desirable to detect whether an intelligent mixed instruction is also received; if the intelligent mixed instruction is received, then subsequent operations are triggered to execute; and if no intelligent mixed instruction is received, then operation is executed according to the implementation manner of the prior art.

It should be herein noted that the implementation manner of the intelligent mixed attribute may be implemented through configuring an instruction, for example: configuring a WINDOW_FLAG_HH instruction (i.e., a window icon display instruction), and may also be implemented through other instructions, which will not be defined herein. Wherein, the intelligent mixed attribute may be added in the desktop background management system and synchronously displayed in a desktop background management display layer.

In step202: display overlapping is performed on the picture and a second display layer including icons.

In step202, when a picture used for change, the icons displayed in the second display layer and the display positions of the icons in the second display layer are displayed; at this moment, display overlapping is performed on the received picture and the second display layer including the icons, i.e., the icons displayed in the second display layer are mapped onto the picture needing to be changed according to a display mode.

It should be noted that the overlapping the display layer herein is namely to place the second display layer onto the first display layer; if the first display layer is called as a first picture layer, and the second display layer is called as a second picture layer, then the overlapping the display layer herein means to perform mixed picture layer operation on the first picture layer and the second display layer.

In step203: the color contrast of the icon in a first area of the second display layer being overlapped onto the picture displayed in the first area of the first display layer is judged whether to be less than a first preset threshold; if the color contrast is less than the first preset threshold, then step204is performed; and if the color contrast is no less than the first preset threshold, then step206is performed.

The color contrast herein refers to the degree of closeness between two colors.

The icon of the second display layer displayed in the first area is determined whether to be recognized by the user through the color contrast when the icon in the first display area of the second display layer is overlapped onto the picture displayed in the first area of the first display layer.

Wherein, the closer the color of the icon in the first display area of the second display layer is to the color of the picture displayed in the first area of the first display layer, the smaller the color contrast of the icon in the first area of the second display layer being overlapped onto the picture displayed in the first area of the first display layer is; on the contrary, the larger the color contrast of the icon in the first area of the second display layer being overlapped onto the picture displayed in the first area of the first display layer is.

In step204: when the color contrast of the icon in the first area of the second display layer being overlapped onto the picture displayed in the first area of the first display layer is less than the first preset threshold, the color contrast in the first area is adjusted, so that the adjusted color contrast is greater than the second preset threshold, the second threshold being greater than or equal to the first threshold.

In step204, the manners for adjusting the color contrast in the first area include, but are not limited to the several manners as follows.

First manner:

a reverse operation is performed on the color of the picture displayed in the first area of the first display layer, and a color after performing the reverse operation is obtained; and

the color of the icon in the first display area of the second display layer is adjusted according to the obtained color, so that the adjusted color contrast of the icon in the first area being overlapped onto the picture displayed in the first area of the first display layer is greater than the second preset threshold.

To be specific, colors may be represented by “abgr” in a computer system. Wherein, a represents transparency, b represents blue, g represents green, and r represents red. When the color visibility of the icon of the second display layer in a first area being overlapped onto the picture displayed in the first area of the first display layer is less than the first preset threshold, the overlapped icon in the first area is determined to be difficultly recognized by the user, which causes inconvenience for the user to subsequently use the functional icon.

In order to improve the identifiability of the icon of the second display layer in a first area, a color mostly different from the color of the picture displayed in the first area of the first display layer may be determined by performing a reverse operation on the color of the picture displayed in the first area of the first display layer; in this way, the color of the icon in the first display area of the second display layer is adjusted according to the obtained color, so that the object of adjusting the color contrast in the first area is achieved, so that the adjusted color contrast of the icon in the first area being overlapped onto the picture displayed in the first area of the first display layer is greater than the second preset threshold, which may be beneficial for increasing the identifiability of the functional icon of the second display layer in the first area.

determining at least one color with a color contrast greater than the second preset threshold when overlapped onto the picture displayed in the first area of the first display layer, according to the color of the picture displayed in the first area of the first display layer;

one color is selected from the determined at least one color; and

the color of the icon in the first area is adjusted according to the selected color to achieve the object of adjusting the color contrast in the first area, so that the adjusted color contrast of the icon in the first area being overlapped onto the picture displayed in the first area of the first display layer is greater than the second preset threshold.

the color of the icon of the first display layer in the first area is adjusted according to the color of the icon in the first display area of the second display layer to achieve the object of adjusting the color contrast in the first area, so that the visibility of the functional icon in the first area being overlapped onto the adjusted picture displayed in the first area of the first display layer is greater than the second preset threshold.

Optionally, adjusting the color of the picture in the first area only may possibly cause the picture displayed in the first display layer to lose a sense of beauty; therefore, under the premise of ensuring that the color contrast of the icon in the first area being overlapped onto the adjusted picture displayed in the first area of the first display layer is greater than the second preset threshold, the method further includes a following step.

The color of the picture displayed in a second area of the first display layer is adjusted according to the adjusted color of the picture displayed in the first area of the first display layer, so that the color of the adjusted picture displayed in the second area of the first display layer is matched with the color of the adjusted picture displayed in the first area, wherein the first display layer includes the first area and the second area.

It should be noted that matching of the color refers to a smaller color contrast which will not cause apparent difference during displaying.

the color of the icon of the first display layer in the first area and the color of the icon in the first display area of the second display layer are adjusted respectively to achieve the object of adjusting the color contrast in the first area, so that the adjusted color contrast of the icon of the second display layer in the first area being overlapped onto the adjusted picture displayed in the first area of the first display layer is greater than the second preset threshold.

Optionally, when adjusting the color contrast in the first area of the second display layer, the method further includes:

when performing display overlapping on the picture with the second display layer including the icons, and when the color contrast of the icon in the second area of the second display layer being overlapped onto the picture displayed in the second area of the first display layer is less than the first preset threshold, the color of the icon in the second area is adjusted, so that the adjusted color contrast of the icon in the second area being overlapped onto the picture displayed in the second area of the first display layer is greater than the second preset threshold.

To be specific, the adjusting the color of the icon in the second area includes:

if the icon in the second area includes words and/or pictures, then the color of the words included in the icon is adjusted primarily, and the color of the pictures included in the icon is adjusted auxiliarily when adjusting the color of the icon in the second area.

It should be herein noted that most icons displayed in the second display layer belong to application icons which not only include pictures, but also include words for interpreting the pictures, for example: a “WeChat” icon including the Logo picture of WeChat and “WeChat” words; that is, the words for interpreting the icon may explain the function of the icon more preferably than the pictures. Therefore, once the words are not clear, the user cannot recognize the icon. Therefore, adjusting the color of the words in the application icon is preferred in the embodiment of the present disclosure, so that the user is ensured to be capable of recognizing the application icon even if the color of the icon is not adjusted, and the processing pressure of the system may be relieved as well.

In step205: the first display layer including the pictures and the second display layer including the icons are displayed into a user interface UI in an overlapping manner according to the adjustment result.

In step205,FIG. 3is a schematic diagram illustrating the picture and the functional icon displayed in the UI according to the adjustment result.

It may be seen fromFIG. 3that icons that cannot be displayed in the circles ofFIG. 1(d)will be visible through the operations of steps203to step205.

In step206: the picture included in the first display layer is displayed according to the manner of the prior art.

The display method and the display device provided by the embodiments of the present disclosure receive the picture sent by the user for being displayed in the first display layer; perform display overlapping on the picture and the second display layer including icons; when the color contrast of the icon in the first area of the second display layer being overlapped onto the picture displayed in the first area of the first display layer is less than the first preset threshold, adjust the color contrast in the first area, so that the adjusted color contrast is greater than the second preset threshold, the second threshold being greater than or equal to the first threshold; and display the first display layer including the pictures and the second display layer including the icons into the user interface UI in an overlapping manner according to the adjustment result. In this way, for the same display area, when the color of the picture displayed in the first display layer and the color of the icon displayed in the second display layer are consistent, the color of the picture and/or the color of the icon is adjusted flexibly, so that the color contrast between the color of the picture and the color of the icon is increased, the display visibility of the icon is improved, the problem that the icon cannot be recognized by the user when the color of the picture displayed in the first display layer is consistent with the color of the icon displayed in the second display layer is solved, and the flexibility of the user for operating the intelligent terminal is increased.
