[0032] With the development and widespread application of computer technology, the color design of display interfaces has become increasingly rich, and the information density of interfaces has also increased significantly. In actual use, the display performance of the terminal devices used by users varies significantly. For example, some low-performance devices cannot accurately display rich color information or accurately represent the brightness differences of different interface elements, which leads to poor readability of interface content and affects the accuracy of interface display.

[0033] Existing methods for evaluating the contrast of display interface content are based on the assumption that display devices have relatively stable brightness output capabilities or color rendering characteristics. This approach does not consider the impact of low-performance display devices (such as those with limited brightness output capabilities, dynamic range, or color performance) on the perceived brightness and contrast of interface elements, and therefore cannot accurately reflect the readability of interface elements in real-world usage environments, thus affecting the accuracy of interface display.

[0034] Based on this, this disclosure provides a method for determining a display interface. By obtaining the display information of the interface to be displayed and the display performance information of the target display device, the physical display performance of the device is introduced as a variable into the evaluation method for the readability of interface elements. The readability of interface elements is determined by combining the display performance parameters of the device, and the interface display parameters are adjusted in a targeted manner when the readability score does not meet the standard, so as to improve the accuracy of the interface display.

[0035] Figure 2 A flowchart of a method 200 for determining a display interface according to an exemplary embodiment of the present disclosure is shown. Figure 2 As shown, method 200 includes: Step S201: Obtain first display information, wherein the first display information includes the foreground display parameters of the target element in the initial display interface and the background display parameters of the initial display interface; Step S202: Obtain the display performance information of the target display device; Step S203: Based on the first display information and display performance information, determine the target information characterizing the readability of the target element in the initial display interface; Step S204: In response to the target information satisfying preset conditions, adjust the first display information based on the target information to obtain the second display information; and Step S205: Adjust the initial display interface based on the second display information to obtain the target display interface.

[0036] By applying the above method 200, the readability of the interface can be determined based on the hardware performance characteristics of the target display device. By combining the device capabilities and the display parameters of the interface to calculate the target information, the perceptual deviation caused by the performance differences of the display devices can be accurately quantified, so as to more accurately determine the readability of the interface in the real use environment (target display device). Then, when the readability risk is high, the interface configuration parameters can be adjusted in a targeted manner to improve the accuracy of the interface display.

[0037] In some examples, the target information characterizing the readability of a target element in the initial display interface is a target score. In one example, the readability of the target element in the initial display interface is scored continuously within a certain numerical range, such as a score based on readability within the range of 0-100. In this case, the preset condition for the target information is, for example, a preset scoring threshold. When the target score is less than or equal to the scoring threshold (e.g., 60 points), the target information is considered to meet the preset condition, and the first display information needs to be adjusted to improve the accuracy of the interface display. In another example, the target score is discretized, that is, the target score label is determined based on the readability of the target element in the initial display interface from multiple preset discrete labels, such as rating the target element based on readability in four discrete level labels: A, B, C, and D. In this case, the preset condition for the target information is, for example, a preset scoring level threshold. When the target score is less than or equal to the scoring threshold (e.g., level C), the target information is considered to meet the preset condition, and the first display information needs to be adjusted to improve the accuracy of the interface display.

[0038] In some examples, the initial display interface can be the user interface of various applications, operating systems, or system software. For example, the initial display interface can be the control panel of a marketing platform, the information feed list of a mobile application, the chat dialog box of social software, the display interface of an in-vehicle system, the interface of an industrial control terminal, or the reading interface on an e-ink screen device.

[0039] In some examples, the target element can be any visual component presented in the initial display interface. For example, the target element can be a text element, such as title text, body paragraphs, explanatory text, etc.; it can also be an icon element, such as function button icons, status indicator icons, etc.; or it can be a line or geometric element, such as the border line of a function area, a dividing line, a progress bar, a drag bar, or a decorative graphic, etc.

[0040] In some examples, the foreground display parameters of a target element are parameters used to define the visual characteristics of the element itself. Foreground display parameters can include brightness values, transparency, hue, saturation, lightness, or contrast. For example, in the RGB color model, foreground display parameters can be represented by specific color values ​​for the red, green, and blue channels; in the RGBA color model, in addition to RGB color values, it also includes an alpha channel parameter representing opacity; in the HSL or HSV color models, it can be represented by values ​​for hue, saturation, and lightness.

[0041] In some examples, background display parameters are data used to define the visual characteristics of the background area where the target element is located. Similar to foreground display parameters, background display parameters can also include the brightness, transparency, or color values ​​of various color channels of the background color. For example, background display parameters can be the RGB color values ​​of a solid color background, the color parameters of a semi-transparent overlay, or the effective color parameters of a white or light-colored background at a specific location. In one example, background display parameters include the display parameters of the global background of the initial display interface. In another example, background display parameters include the display parameters of the local background area surrounding the target element. For example, when the target element is text or an icon located on a semi-transparent floating card, the background display parameters are used to specifically indicate the local background color and brightness of the floating card at the location of the target element, thereby more accurately reflecting the contrast between the display effect of the target element and its directly contacting area.

[0042] In some examples, the display performance information in step S202 is a quantitative parameter characterizing the physical display capabilities of the target display device. For instance, display performance information can characterize the target display device's peak brightness output capability, native panel contrast ratio, effective dynamic range, black level control capability, grayscale resolution capability, color gamut coverage capability, and dynamic response capability of the display driving circuit. This information reflects the actual output limits and attenuation characteristics of the device when displaying content with brightness differences and semi-transparent colors.

[0043] In some examples, step S203 can be calculated using a multi-stage perceptual contrast model that includes a device capability correction module. For example, firstly, based on the foreground display parameters and background display parameters in the first display information, a conventional perceptual contrast model is applied to calculate the basic perceptual contrast value of the target element in the initial display interface. Further, the basic perceptual contrast value is corrected using display performance information characterizing the display capability of the target display device. Specifically, a brightness display capability correction factor can be calculated based on the hardware performance parameters of the display device (e.g., parameters characterizing brightness output capability or dynamic range) to simulate the device's compression effect on overall contrast. Alternatively, if the target element includes semi-transparent content, a transparency compensation factor can be calculated by combining the transparency value of the semi-transparent content with parameters characterizing the device's transparency color display attenuation characteristics. By fusing the basic perceptual contrast value with the aforementioned correction or compensation factors (e.g., multiplication, weighted calculation, or exponential calculation), target information reflecting the readability of the target element in a real device display environment can be obtained.

[0044] According to some embodiments, the foreground display parameters and background display parameters include at least one feature dimension, the at least one feature dimension including at least one of the following: brightness dimension, transparency dimension or color feature dimension, and the display performance information includes display performance parameters corresponding to the at least one feature dimension, the display performance parameters corresponding to each feature dimension being used to characterize the performance capability of the target display device for that feature dimension.

[0045] By breaking down display parameters and device display performance parameters into specific feature dimensions, the readability of target elements can be determined more accurately. By introducing corresponding display performance parameters for different dimensions such as brightness, transparency, or color, targeted compensation can be made for display effect deviations in specific scenarios (e.g., semi-transparent overlay graying attenuation, low brightness contrast compression), thereby improving the accuracy of readability information.

[0046] In some examples, in addition to brightness, transparency, and color feature dimensions, the feature dimensions may also include contrast, dynamic range, grayscale response, color gamut, or spatial frequency dimensions, based on which the readability of the target element can be determined more accurately, thereby improving display accuracy.

[0047] According to some embodiments, the foreground display parameters and background display parameters include a color feature dimension and a transparency dimension. The display performance information includes a first performance parameter characterizing the degree of display attenuation of transparent colors by the target display device. In step S203, based on the first display information and the display performance information, the target information characterizing the readability of the target element in the initial display interface includes: determining first information characterizing the degree of color perception contrast based on the color feature values ​​of the foreground display parameters and the color feature values ​​of the background display parameters; determining second information characterizing the degree of display attenuation of transparent colors based on the transparency value of the foreground display parameters and the first performance parameter; and determining target information based on the first information and the second information.

[0048] By calculating the first information of color perception contrast and the second information of transparent color attenuation separately, and then combining the two to obtain the target information, the contrast loss caused by the transparency of interface content in actual device rendering can be more accurately quantified. For display interfaces containing semi-transparent overlay elements, the readability can be determined more accurately, thereby improving the accuracy of interface display.

[0049] In some examples, the first and second information are in the form of ratings, such as continuous numerical ratings, to more accurately characterize the degree of color perception contrast and the degree of attenuation of transparent color display.

[0050] In practical applications, color feature values ​​are used to quantify the color attributes of interface elements. Taking the RGB color model as an example, color feature values ​​can be represented as pixel grayscale values ​​or luminance of the three channels: red, green, and blue. In the HSV or HSL color models, color feature values ​​are specifically expressed as values ​​for hue, saturation, and lightness. In the LAB color space, color feature values ​​can be represented as lightness components (L dimension values) and chromaticity components (A dimension values ​​and B dimension values), thus more accurately representing the content of interface elements.

[0051] According to some embodiments, determining the first information characterizing the degree of color perception contrast based on the color feature values ​​of the foreground display parameters and the background display parameters includes: determining the equivalent foreground color feature value of the target element based on the transparency value of the foreground display parameters, the color feature values ​​of the foreground display parameters, and the color feature values ​​of the background display parameters; and determining the first information based on the equivalent foreground color feature value and the color feature values ​​of the background display parameters.

[0052] By applying the above method to calculate the equivalent foreground color feature value of interface elements, the transparency blending process can be simulated more accurately. By performing pixel-level fusion of foreground elements with transparency with the underlying background, the actual color rendered on the screen can be restored. Compared with the calculation method that simply relies on the original foreground color value, the basic contrast calculation error is reduced, and the accuracy of determining the readability of interface elements is improved.

[0053] In some examples, determining the primary information based on the color feature values ​​of the foreground and background can employ other computational strategies. For instance, the relative brightness of the foreground and background colors can be directly extracted and calculated using the Weber-Fechner law or the existing WCAG contrast formula (i.e., the ratio of the relative brightness of the brighter color plus a fixed bias to the relative brightness of the darker color plus a fixed bias) to obtain the primary information. Alternatively, the color feature values ​​of both can be converted to a uniform color space, the color difference matrix distance between them can be directly calculated, and this distance can be mapped to primary information representing the degree of color perception contrast.

[0054] According to some embodiments, determining the second information characterizing the degree of attenuation of transparent color display based on the transparency value of the foreground display parameter and the first performance parameter includes: performing an exponential calculation by using the transparency value of the foreground display parameter and the first performance parameter as the base and exponent, respectively, to obtain the second information.

[0055] By combining the transparency value with the first performance parameter through exponential calculation, the non-linear optical attenuation characteristics of the screen hardware when presenting semi-transparent materials can be more accurately fitted. This allows the second information to accurately characterize the contrast loss phenomenon that occurs when a low-performance display screen processes semi-transparent elements, thereby more accurately determining the readability of semi-transparent interface elements.

[0056] It should be understood that the methods for determining the second information are not limited to the exponential calculation methods described above. In some examples, a linear calculation method can be used, where the transparency value of the foreground display parameter is weighted and added or multiplied by the first performance parameter to obtain the second information. For another example, a logarithmic decay model can be used, where the first performance parameter is multiplied by the logarithm of the transparency value of the foreground display parameter to obtain the second information. Alternatively, based on a pre-established lookup table, the transparency value of the foreground display parameter and the first performance parameter can be used as indexes for interpolation to obtain the corresponding second information representing the degree of transparency decay.

[0057] After obtaining the first and second information, the final target information can be determined through various mathematical fusion methods. For example, the second information can be used as a weighting factor or compensation coefficient, directly multiplied with the first information to simulate the proportional decrease in contrast when the base color contrast is superimposed with the attenuation effect of transparent color. Alternatively, empirically based weighting coefficients can be assigned to the first and second information respectively, and the target information can be obtained through a weighted summation.

[0058] According to some embodiments, the first performance parameter of the target display device is determined based on the brightness display sampling results or color display sampling results of a first sample including content with different transparent colors on the target display device. By directly using the sampling results to calibrate the device characteristics, the actual display effect of the target display device can be more accurately characterized based on the device performance parameters based on the actual calibration process, thereby improving the accuracy of the interface readability score.

[0059] In one example, the calibration process for the first performance parameter of the target display device is implemented as follows: a set of first sample images containing color blocks with various transparency gradients are pre-made and rendered on the target display device. Then, an optical luminance meter or colorimeter is used to perform actual optical sampling measurements on each transparency color block displayed on the screen. The measured actual brightness or color data is compared and fitted with the theoretically calculated ideal rendering data to extract the coefficients characterizing the transparency display decay curve of the target display device. The transparency display decay curve characterizes the functional relationship curve between the transparency of the interface content and the degree of display decay. This coefficient can be used as the first performance parameter of the target display device.

[0060] Besides optical sampling using physical instruments, the primary performance parameter can also be determined quickly in other ways. For example, it can be determined by reading the hardware configuration identifier of the target display device (such as the panel model) and then searching a pre-set device performance database to match the pre-entered primary performance parameter, or by manually performing calibration tests to label the primary performance parameters of different target display devices.

[0061] According to some embodiments, the foreground display parameters and background display parameters include a color feature dimension and a brightness dimension, and the display performance information includes a second performance parameter characterizing the target display device's ability to represent brightness differences. In step S203, the target information characterizing the readability of the target element in the initial display interface based on the first display information and the display performance information includes: determining first information characterizing the degree of color perception contrast based on the color feature values ​​of the foreground display parameters and the background display parameters; determining third information characterizing the accuracy of brightness difference performance based on the second performance parameters of the target display device and the second performance parameters of the reference display device; and determining target information based on the first information and the third information.

[0062] By introducing a second performance parameter representing the ability to represent brightness differences into the interface content readability determination algorithm and comparing it with a benchmark display device, the impact of performance differences in overall brightness output and dynamic range of different display devices on the readability of interface content can be compensated. Based on this, the readability of the display interface content on various different devices can be determined more accurately, thereby improving the cross-device compatibility of the optimized target display interface and improving the accuracy of interface display.

[0063] In some examples, the third information is in the form of a rating, such as a continuous numerical rating, to more accurately characterize the accuracy of brightness difference performance.

[0064] In some examples, the benchmark display device corresponds to a high-performance display with standard color reproduction capabilities and brightness output range. This benchmark display device can be selected based on hardware performance parameters such as the display device's peak brightness output capability, native panel contrast ratio, effective dynamic range, black level control capability, grayscale resolution capability (distinguishing grayscale levels), backlight structure, display driver, and dimming control precision. In one example, the benchmark display device can be virtually characterized using a set of benchmark display performance parameters (i.e., the second performance parameters of the benchmark display device) to represent standard display performance.

[0065] In some examples, a second performance parameter of the target display device can be extracted and compared with the second performance parameter of a reference display device, and a third piece of information can be determined based on the comparison result. For example, the second performance parameters of the two devices can be divided to obtain a ratio coefficient, or the difference between the two devices can be calculated. Furthermore, the calculated ratio coefficient or difference can be processed through a non-linear mapping function, such as converting the difference in device capabilities into a normalized discount coefficient between 0 and 1, as the third piece of information characterizing the accuracy of the target device's brightness performance.

[0066] In some examples, after obtaining the first and third information, the third information can be used as a global correction factor for the base contrast. For instance, the first and third information can be multiplied directly to simulate the discounting effect of dynamic range compression on the base color perception contrast of low-performance display devices, or the influence weight can be calculated based on the third information and superimposed on the first information to obtain the target information.

[0067] According to some embodiments, the second performance parameter of the target display device is determined based on the brightness display sampling results of a second sample including content of different brightness on the target display device. By determining the second performance parameter based on the actual brightness display sampling results, the device performance parameter based on the actual calibration process can more accurately characterize the actual display effect of the target display device. For example, it can more accurately characterize the degree of compression and distinguishability of the display device when presenting brightness differences, thereby improving the accuracy of the interface readability score.

[0068] In one example, the calibration process for the second performance parameter of the target display device is implemented as follows: a second sample image containing a standard grayscale test map from pure black to pure white is presented on the target display device, and then the absolute luminance value of each luminance level actually output on the screen is measured using an optical luminance meter or colorimeter. Based on this, the second performance parameter can be determined by analyzing the ratio of the highest absolute luminance to the black level luminance or the deviation of the fitted device response curve.

[0069] Besides optical sampling using physical instruments, the second performance parameter can also be determined in other ways. For example, the corresponding second performance parameter can be read by directly querying preset parameters such as the display device's maximum supported brightness and factory-set contrast ratio.

[0070] In some examples, the first piece of information representing color perception contrast, the second piece of information representing the attenuation of transparent colors, and the third piece of information representing the accuracy of brightness differences can be used together. For example, the first piece of information can be used as a base value, combined with the second piece of information to correct for local contrast loss caused by semi-transparent content in the initial display interface, and then the result can be multiplied by the third piece of information to determine the display effect discount caused by the difference in brightness display performance of the display device, thereby more comprehensively and accurately reflecting the readability of elements with transparent properties when presented on different display devices.

[0071] According to some embodiments, method 200 further includes: determining the element type of the target element, including graphics or text; in response to determining that the target element is text, determining the font size or weight of the target element; determining a text perception score characterizing the readability of the text based on the font size or weight of the target element; and adjusting the target information based on the text perception score. This enables more refined perception compensation for text objects, more accurately determining the readability of text content, thereby improving the accuracy of text display on the interface.

[0072] In this example, font size refers to the physical or logical size of the text characters in screen space, which determines the size of the display area occupied by the text, while font weight refers to the thickness of the text strokes, which determines the relative proportion of the display area occupied by the text lines.

[0073] In some examples, the element type of the target element can be further categorized into finer-grained categories. For instance, target elements of graphic or image type can be further subdivided into control outlines (such as the border line of an input box), status indicators (such as unread message red dots, battery icons), background fill blocks, interactive trigger areas, etc. Based on this, the readability of different types of target elements can be more accurately determined, and more precise adjustments to interface display parameters can be made to improve the accuracy of interface display.

[0074] In some examples, a mapping relationship can be established between font size, font weight, and perceptual sensitivity to determine the text perception score. For instance, when the font size of a target element is smaller than a preset standard size, or the font weight is thin, the system assigns it a text perception score less than 1 to indicate poor readability and an increased risk of inaccurate display. Conversely, for large-font or extremely bold text, a score equal to or slightly greater than 1 is assigned to reflect its inherent high recognizability. Based on this, the readability of text content can be determined more accurately, thereby improving the accuracy of text display on the interface. After obtaining the text perception score, it can be used as an adjustment factor directly on the aforementioned target information. For example, the target information can be multiplied by the text perception score. If the text is small and thin (i.e., the text perception score is low), the multiplication operation will lower the final target information, thereby triggering adjustment steps for that text element to improve display accuracy.

[0075] In step S204, when the target information is found to meet preset conditions (e.g., the target score is less than or equal to a preset scoring threshold), an adjustment strategy can be dynamically generated based on the difference between the target information and the preset conditions (e.g., the difference between the target score and the scoring threshold). Specific adjustment methods may include: automatically increasing the opacity in the foreground display parameters; increasing the color difference between the foreground and background (e.g., lowering the background brightness or increasing the foreground brightness); for text elements, style rewriting can be triggered to increase their font size or weight, thereby obtaining optimized second display information. Based on this, step S205 can then be used to obtain a target display interface corresponding to the optimized second display information. This target display interface has better readability, thereby improving the accuracy of the interface display.

[0076] In some examples, step S204 can also match the target score with preset score ranges corresponding to different risk levels to generate discretized, readable risk level information, such as low-risk, medium-risk, and high-risk levels. In one example, when the target information is a percentage-based score, a target score below 60 can be mapped to a high-risk level, a target score between 60 and 80 to a medium-risk level, and a target score above 80 to a high-risk level. Based on this, adjustments can be made to the initial display interface for specific risk levels (e.g., high-risk levels) to improve display accuracy.

[0077] In some examples, after the above parameter adjustment steps are completed and the target display interface is obtained, specific drawing instructions can be generated based on the adjusted target display interface, rendering the visual target display interface and displaying it on the screen of the target display device.

[0078] In some examples, the above method 200 can also be applied during the interface development and testing phase based on the display performance parameters of different display devices to determine whether the initial display interface meets the requirements on different display devices. Based on this, the display parameter configuration of the display interface can be optimized, thereby improving the accuracy of the interface display.

[0079] Figure 3 A flowchart of a method 300 for determining a display interface according to an exemplary embodiment of the present disclosure is shown. Figure 3 As shown, method 300 includes: Step S301: Obtain first display information. In this example, the first display information includes the foreground display parameters of the target element in the initial display interface and the background display parameters of the initial display interface. The foreground display parameters and the background display parameters include brightness dimension, transparency dimension, or color feature dimension.

[0080] Step S302: Obtain the display performance information of the target display device. In this example, the display performance information includes a first performance parameter characterizing the degree of display attenuation of transparent colors by the target display device and a second performance parameter characterizing the target display device's ability to handle brightness differences.

[0081] Step S303: Determine the first score representing the degree of color perception contrast based on the color feature values ​​of the foreground display parameters and the background display parameters.

[0082] Step S304: Determine a second score characterizing the degree of attenuation of transparent color display based on the transparency value of the foreground display parameter and the first performance parameter.

[0083] Step S305: Based on the second performance parameters of the target display device and the second performance parameters of the reference display device, determine the third score characterizing the accuracy of brightness difference performance.

[0084] Step S306: Determine the target score representing the readability of the target element in the initial display interface based on the first score, the second score, and the third score.

[0085] Step S307: In response to the target score being less than or equal to the score threshold, adjust the first display information based on the target score to obtain the second display information.

[0086] Step S308: Adjust the initial display interface based on the second display information to obtain the target display interface.

[0087] By applying the above method 300, the readability of the interface can be determined based on the hardware performance characteristics of the target display device. By combining the device capabilities and the display parameters of the interface to calculate the target score, the perceptual deviation caused by the performance differences of the display devices can be accurately quantified. This allows for a more accurate determination of the readability of the interface in the real usage environment (target display device). Furthermore, when the readability risk is high, the interface configuration parameters can be adjusted in a targeted manner to improve the accuracy of the interface display.
