Description

This application claims priority to Chinese Patent Application No. 201910568981.2, filed with the China National Intellectual Property Administration on Jun. 27, 2019 and entitled “METHOD FOR ADJUSTING DISPLAY ATTRIBUTE, AND RELATED DEVICE”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of this application relate to the field of terminal devices, and in particular, to a method for adjusting a display attribute, and a related device.

BACKGROUND

A contrast ratio refers to a range of differences in different brightness levels between brightest white and darkest black in bright and dark regions in an image. Generally, a smaller range of differences indicates a smaller contrast ratio.

In a conventional technology, a display attribute of an element displayed by a terminal device on a page is relatively independent of a display attribute of a background region in which the element is displayed. In this solution, when the display attribute of the background region in which the element is displayed on the page changes, a contrast ratio between the element and the background region may be decreased. Consequently, a display effect of the element in the background may be not prominent, which may deteriorate reading experience of a user.

DESCRIPTION OF EMBODIMENTS

In the specification, claims, and accompanying drawings of this application, the terms “first”, “second”, “third”, “fourth”, and so on (if existent) are intended to distinguish between similar objects but do not necessarily indicate a specific order or sequence. It should be understood that the data termed in such a way are interchangeable in proper circumstances so that the embodiments of this application described herein can be implemented in other orders than the order illustrated or described herein. Moreover, the terms “include”, “have”, and any other variants mean to cover the non-exclusive inclusion, for example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those units, but may include other units not expressly listed or inherent to such a process, method, system, product, or device.

For ease of understanding, the following first describes an application scenario used in the embodiments of this application.

Generally, a user may set, based on preference of the user, a background of a page displayed by a terminal device. For example, the user may set a screen lock interface. As shown in FIG. 1, the user may switch a background on a left side of FIG. 1 to a background on a right side of FIG. 1. In this process, the user sets only the background of the page, and does not set an element displayed on the page. In this case, a contrast between the background on the right side of FIG. 1 and the element of the page may not be obvious. As a result, the element is not prominently displayed in the background of the page. In this case, the terminal device may adjust the page by using the method provided in an embodiment of this application, so that the element can be prominently displayed on the background while the background set by the user is kept, thereby improving reading experience of the user.

In this embodiment, the terminal device is a device with a display apparatus, and the display apparatus may be a black-and-white display apparatus, or may be a color display apparatus. This is not limited herein. Specifically, the terminal device may be a mobile phone, a tablet computer, or another device with a display apparatus. In this embodiment and subsequent embodiments, only a terminal device is used as an example for description.

For ease of understanding, the following describes, with reference to the foregoing application scenario, a procedure of the method for adjusting a display attribute. Specifically, as shown in FIG. 2, the terminal device performs the following steps.

201. Obtain a first luminance and a second luminance on a page.

The first luminance is a luminance of an element on the page. The second luminance is a luminance of a background region in which the element is displayed. The luminance refers to a degree of brightness and darkness of the page. The luminance is unrelated to a color of the page. Using FIG. 3A as an example, in the figure, the luminance is divided into 12 levels, which gradually become darker from 50 to 900. When the darkest level is reached, the region is displayed as black, and when the brightest level is reached, the region is displayed as white. In actual application, if the terminal device divides the luminance into the 12 levels shown in FIG. 3A, the first luminance and the second luminance may fall into one or two levels of the 12 levels. Certainly, due to a difference in actual application requirements, the terminal device may alternatively divide the luminance into more levels. This is not specifically limited herein.

In addition, the element includes a text or an icon. For ease of understanding, the following provides description with reference to FIG. 3B. As shown in FIG. 3B, the element may be a text, for example, numbers shown in 301 and Chinese characters shown in 302. The element may alternatively be an icon, for example, an icon that represents a fingerprint shown in 303. In actual application, the element may alternatively be another text or icon. This is not specifically limited herein.

Specifically, a region shown in 301 in FIG. 3B is used as an example. “06:00” in the dashed line region shown in 301 is the element, and a luminance of pixels of strokes that display “06:00” is the first luminance. A luminance of pixels other than “06:00” in the dashed line region shown in 301 is the second luminance.

In this embodiment, after the terminal device obtains the first luminance and the second luminance, the terminal device performs step 202.

202. Determine a first contrast ratio between the element and the background region based on the first luminance and the second luminance.

In this embodiment, after obtaining the first luminance and the second luminance, the terminal device may determine the first contrast ratio between the element and the background region based on the first luminance and the second luminance. The contrast ratio refers to a difference in different brightness levels between brightest white and darkest black in bright and dark regions on the page. A larger difference indicates a larger contrast ratio, and a smaller difference indicates a smaller contrast.

Specifically, the terminal device may calculate the first contrast ratio by using a plurality of algorithms. This is not specifically limited herein. In this embodiment and subsequent embodiments, the first contrast ratio is determined by a ratio between luminances. For ease of understanding, the following provides description with reference to a specific example. Assuming that a value of the first luminance is less than that of the second luminance, in this case, the terminal device may calculate a ratio of the value of the second luminance to the value of the first luminance, to obtain the first contrast ratio. In this case, the terminal device may compare the first contrast ratio with a preset contrast ratio. The preset contrast ratio may be a contrast ratio preset during production of the terminal device, or may be a contrast ratio set by a user based on a use habit. This is not specifically limited herein. Generally, the preset contrast ratio may be set to 4.5:1. When the first contrast ratio is less than the preset contrast ratio, the terminal device performs step 203.

203. Adjust a line thickness value of the element.

In this embodiment, the display attribute of the element includes the line thickness value of the element. Generally, a larger line thickness value indicates a thicker line.

Specifically, when the element is a text, the line thickness value of the element indicates a thickness of a stroke of the text. For example, a text shown in FIG. 3C may be divided into a total of 12 values: 25 JF to 105 JF.

In addition, when the element is an icon, the line thickness value of the element indicates a line thickness of the icon. For example, a thickness value of an icon shown in FIG. 3D constantly increases from left to right, and a line thickness of the icon also constantly increases.

In this embodiment, when the first contrast ratio is less than the preset contrast ratio, the terminal device may adjust the line thickness value of the element. Specifically, the terminal device may adjust the line thickness value of the element based on a preset correspondence and the first contrast ratio, where the preset correspondence is a correspondence between the first contrast ratio and the line thickness value of the element. More specifically, the terminal device may determine, based on a difference between the preset contrast ratio and the first contrast ratio, a quantity of thickness levels for adjustment. For ease of understanding, description is provided with reference to an example shown in Table 1.

When the first contrast ratio is 3:1 and the preset contrast ratio is 4.5:1, because the first contrast ratio is less than the preset contrast ratio, the terminal device may calculate a difference between the preset contrast ratio and the first contrast ratio, and adjust the line thickness value of the element based on a correspondence between the difference and the quantity of thickness levels for adjustment in Table 1. For example, when the difference between the preset contrast ratio and the first contrast ratio is 1.5, the line thickness value of the element is increased by three levels. Assuming that an initial line thickness level of the element is 55S shown in FIG. 3C, a line thickness of the element is adjusted to 70S.

In this embodiment, in addition to adjusting the line thickness value of the element based on the foregoing preset thickness levels, the terminal device may further calculate the thickness value based on the first luminance and the second luminance. For ease of understanding, the following formula is used as an example for description. It is assumed that when the second luminance is the darkest (that is, pure dark), the value of the second luminance is 0; when the second luminance is the brightest (that is, pure white black), the value of the second luminance is 1000; and 570 is selected as a median value of the luminance. If preset line thickness values of the element are S₀, S₁₀₀₀, and S₅₇₀, when the second luminance changes, the line thickness value s_lof the element is as follows:

$s_{l} = {\begin{matrix} s_{0} + \frac{s_{5 7 0} - s_{0}}{5 7 0} l & 0 < l < 570 \\ s_{5 7 0} + \frac{s_{1 0 0 0} - s_{5 7 0}}{4 3 0} (l - 570) & 5 70 < l < 1000 \end{matrix}$

Specifically, in actual application, the calculation formula may vary with an application scenario. This is not specifically limited herein.

In this embodiment, for ease of understanding, only the element 301 shown in FIG. 3B is used as an example to display an adjustment effect. After the terminal device adjusts the line thickness value of the element in the foregoing manner, for a display effect of the page, refer to FIG. 4A. A left side of FIG. 4A shows an element whose line thickness value is not adjusted, and a right side of FIG. 4A shows an element whose line thickness value is adjusted. In this case, lines of the element on the page become thicker, so that the user can more easily distinguish, during reading, the element from the background in which the element is displayed. Therefore, reading experience of the user can be appropriately improved.

204. Adjust a luminance of the element.

Step 204 is an optional step, and there is no explicit limitation on a time sequence between step 204 and step 203.

When the first contrast ratio is less than the preset contrast ratio, the terminal device adjusts the luminance of the element, where the element is a text or an icon. Specifically, the terminal device may adjust the luminance of the element to a first target luminance, where a second contrast ratio between the first target luminance and the luminance of the background region is greater than the preset contrast ratio. For ease of understanding, the following provides description with reference to a specific example. It is assumed that the first luminance is less than the second luminance, the first luminance is 100, and the first luminance is 300. In this case, a ratio of the second luminance to the first luminance is 3:1, which is less than 4.5:1. Therefore, the terminal device adjusts the first luminance to the first target luminance, provided that the first target luminance is less than 100.

In this embodiment, for ease of understanding, the element 301 shown in FIG. 3B is still used as an example to display an adjustment effect. After the terminal device adjusts the luminance of the element in the foregoing manner, for a display effect of the page, refer to FIG. 4B. A left side of FIG. 4B shows an element whose luminance is not adjusted, and a right side of FIG. 4B shows an element whose luminance is adjusted. In this case, lines of the element on the page become brighter, so that the user can more easily distinguish, during reading, the element from the background in which the element is displayed. Therefore, reading experience of the user can be appropriately improved.

205. Set a shadow of the element.

Step 205 is an optional step, and there is no explicit limitation on a time sequence between step 205 and steps 203 and 204.

When the first contrast ratio is less than the preset contrast ratio, the terminal device may set the shadow of the element, where a color of the shadow is different from that of the element. For ease of understanding, in this embodiment, the element 301 shown in FIG. 3B is still used as an example to display an adjustment effect. After the terminal device adjusts the shadow of the element in the foregoing manner, for a display effect of the page, refer to FIG. 4C and FIG. 4D. A left side of FIG. 4C and a left side of FIG. 4D show an element whose shadow is not adjusted. A right side of FIG. 4C shows a scenario in which the shadow overlaps a text. In this case, the shadow forms outer edge lines of the text. A right side of FIG. 4D shows a scenario in which the shadow does not completely overlap the text. In this case, an effect of illuminating the text by a light source on the left side is presented. In actual application, the terminal device may further set another type of shadow effect, to meet preference requirements of different users.

206. Adjust a luminance of the background region.

Step 206 is an optional step, and there is no explicit limitation on a time sequence between step 206 and steps 203 to 205.

In this embodiment, when the first contrast ratio is less than the preset contrast ratio, the terminal device may adjust the luminance of the background region to a second target luminance, where a third contrast ratio between the second target luminance and the luminance of the element is greater than the preset contrast ratio. For ease of understanding, the following provides description with reference to a specific example. It is assumed that the first luminance is less than the second luminance, the first luminance is 100, and the second luminance is 300. In this case, a ratio of the second luminance to the first luminance is 3:1, which is less than 4.5:1. Therefore, the terminal device adjusts the second luminance to a second target luminance, provided that the second target luminance is less than 100.

In this embodiment, the element 301 shown in FIG. 3B is still used as an example to display an adjustment effect. After the terminal device adjusts the luminance of the background region in the foregoing manner, for a display effect of the page, refer to FIG. 4E. A left side of FIG. 4E shows an element that is not adjusted, and a right side of FIG. 4E shows an effect obtained after the luminance of the background region is adjusted. In this case, because the background region becomes darker, lines of the element on the page become brighter, so that the user can more easily distinguish, during reading, the element from the background in which the element is displayed. Therefore, reading experience of the user can be appropriately improved.

The foregoing describes the method for adjusting a display attribute in this embodiment of this application. The following describes a terminal device used in the method for adjusting a display attribute. Specifically, as shown in FIG. 5, the terminal device 50 includes:

The terminal device may adjust the line thickness value based on the first contrast ratio, so that the element corresponding to the adjusted line thickness value can be prominently displayed on the page, thereby improving reading experience of a user.
