Description

Technical Field

[0001] The present disclosure relates to the field of mobile terminal applications, and in particular to a method, device, equipment, medium and program product for determining ambient brightness. Background Art

[0002] It is very common for mobile terminals on the market (including but not limited to tablets, mobile phones, laptops, etc.) to use organic electroluminescence displays (OLED) and light sensors (also known as brightness sensors or light sensors). In actual use, the ambient brightness is collected by the light sensor, and the brightness of the OLED screen is automatically adjusted according to the ambient brightness. However, since the light sensor is usually set below the screen, the light on the screen is easy to leak to the light sensor, resulting in inaccurate brightness values ​​collected by the light sensor.

[0003] The traditional light leakage compensation solution is to perform a dark light calibration on the production line, and then determine the actual brightness value based on the brightness value collected by the light sensor and the calibration value.

[0004] However, the traditional light leakage compensation solution is only for liquid crystal display (LCD) screens. Since the structure and light-emitting principle of OLED screens are different from those of LCD screens, if the traditional light leakage compensation solution is directly applied to the application scenarios corresponding to OLED screens, the accuracy of light leakage compensation cannot be guaranteed. Summary of the invention

[0008] The present disclosure provides a device for determining ambient brightness, including:

[0019] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0020] The following describes the method for determining the ambient brightness of the embodiment of the present disclosure with reference to the accompanying drawings. The method can be applied to an ambient brightness determination device, such as Figure 1 As shown, the method for determining the ambient brightness includes:

[0021] S101, obtaining a first brightness value collected by a light sensor, a second brightness value of a display screen, and a pixel color of each pixel in a preset area of ​​the display screen, where the preset area is adjacent to the light sensor.

[0022] Among them, the first brightness value is the brightness value collected by the light sensor. Due to the existence of light leakage, the first brightness value can be understood as the superposition of the actual brightness of the environment in which the mobile device is located and the leakage brightness. The second brightness value is the actual brightness value of the display screen. The preset area of ​​the display screen is the area of ​​the display screen that is adjacent to the light sensor and whose color and brightness will have a greater impact on the light sensor. The preset area is set by the staff according to the actual situation. For example, the preset area can be the display screen area outside the light sensor and within 3 pixels from the boundary of the light sensor.

[0023] Specifically, a first brightness value collected by a light sensor is obtained, a second brightness value of a display screen detected by a brightness detection device is obtained, and the pixel color of each pixel contained in a preset area of ​​the display screen is obtained. The pixel color acquisition method includes but is not limited to reading the RGB value of each pixel and determining the pixel color according to the RGB value. It should be noted here that the pixel color in the preset area may be one or more.

[0024] S102: Acquire a standard light leakage value corresponding to the pixel color and a brightness level corresponding to the second brightness value from a preset calibration data set.

[0025] The preset calibration data set includes data generated when light leakage calibration is performed on the product line and a mapping relationship between brightness values ​​and brightness levels.

[0026] The light leakage calibration process is completed before S101. The number of light leakage calibrations corresponds to the type of color, and the data generated by the light leakage calibration is the standard light leakage value corresponding to the color. In this embodiment, the preset calibration data set may include standard light leakage values ​​of multiple common colors. When performing light leakage calibration, the mobile device is placed in a preset ambient brightness (such as a completely dark environment with a brightness of 0), the colors of all pixels covering the preset area of ​​the display screen are set to a preset color (such as yellow), the colors of all pixels in the display screen except the preset area are set to white, and the brightness of the display screen is set to the maximum value. At this time, the brightness value collected by the light sensor is the standard light leakage value corresponding to the preset color (that is, the standard light leakage value corresponding to yellow). It can be understood that the standard light leakage value is the maximum brightness of the light leakage of the display screen when the preset area is the preset color. In actual use, the light leakage brightness will change with the brightness of the display screen and the brightness and darkness of the pixel colors in the preset area.

[0027] The mapping relationship between the brightness value and the brightness level is obtained by the staff based on multiple experiments, and the mapping relationship between the brightness value and the brightness level can be presented through the screen brightness curve.

[0028] Specifically, when there is only one pixel color in the preset area, the standard light leakage value corresponding to the pixel color is obtained from the preset calibration data set. When there are multiple pixel colors in the preset area, the standard light leakage value corresponding to each pixel color is obtained from the preset calibration data set. In addition, the brightness level corresponding to the second brightness value needs to be obtained from the preset calibration data set.

[0029] S103: Determine the ratio of the brightness level to the preset maximum brightness level as the backlight brightness ratio.

[0030] Specifically, the ratio of the brightness level corresponding to the second brightness value to the preset maximum brightness level is used as the backlight brightness ratio. For example, if the brightness level corresponding to the second brightness value is 300 and the preset maximum brightness level is 2048, then the backlight brightness ratio is 300 / 2048.

[0031] S104: Determine a first actual light leakage value according to the standard light leakage value and the backlight brightness ratio.

[0032] The first actual light leakage value indicates that the preset area is a pixel color, and when the brightness of the display screen is a second brightness value, the brightness value collected by the light sensor and missed by the display screen. It is easy to understand that the first brightness value includes the first actual light leakage value.

[0033] Specifically, when there is only one pixel color in the preset area, the product of the standard light leakage value corresponding to the pixel color and the backlight brightness ratio is directly used as the first actual light leakage value. When there are multiple pixel colors in the preset area, it is first necessary to calculate the first average light leakage value based on the standard light leakage values ​​corresponding to all pixel colors; then the product of the first average light leakage value and the backlight brightness ratio is used as the first actual light leakage value.

[0034] For example, there is only one pixel color in the preset area, that is, yellow. The standard light leakage value Lux-Yellow corresponding to yellow is obtained in S102, and the first actual light leakage value=Lux-Yellow×backlight brightness ratio.

[0035] For example, there are 10 pixel blocks in the preset area, including 3 pixel blocks with yellow pixel color, 3 pixel blocks with blue pixel color and 4 pixel blocks with white pixel color. The standard light leakage value Lux-Yellow corresponding to yellow, the standard light leakage value Lux-Blue corresponding to blue, and the standard light leakage value Lux-White corresponding to white are obtained through S102. First, according to the standard light leakage values ​​of the pixel colors corresponding to all pixel blocks in the 10 pixel blocks, the first average light leakage value is calculated. In this embodiment, the first average light leakage value = (Lux-Yellow×3+Lux-Blue×3+Lux-White×4) / 10; the first actual light leakage value = the first average light leakage value × backlight brightness ratio.

[0036] S105: Determine the difference between the first brightness value and the first actual light leakage value as the target brightness value.

[0037] The target brightness value is the brightness value corresponding to the environment where the mobile terminal is located.

[0038] Specifically, due to the light leakage problem of the display screen, the first brightness value collected by the light sensor disposed under the display screen includes both the ambient brightness and the brightness of the leakage light. Therefore, after obtaining the first actual light leakage value through S104, the difference between the first brightness value and the first actual light leakage value is determined as the target brightness value. The adjustment device in the mobile device automatically adjusts the brightness of the display screen according to the target brightness value, so that the adjusted screen brightness achieves the best visual effect.

[0039] The method for determining ambient brightness provided in the present embodiment, after obtaining the first brightness value collected by the light sensor, the second brightness value of the display screen and the pixel color of each pixel in the preset area of ​​the display screen, obtains the standard light leakage value corresponding to the pixel color and the brightness level corresponding to the second brightness value from the preset calibration data set; first, the ratio of the brightness level to the preset maximum brightness level is determined as the backlight brightness ratio; then, according to the standard light leakage value and the backlight brightness ratio, the first actual light leakage value is determined; finally, the difference between the first brightness value and the first actual light leakage value is determined as the target brightness value; the scheme provided in the present embodiment, combined with the self-luminous characteristics of the OLED screen, in the process of determining the first actual light leakage value, not only the influence of the actual brightness of the display screen on the leakage brightness is considered, but also the influence of the pixel color of the preset area of ​​the display screen on the leakage brightness is considered, thereby improving the accuracy of the target brightness value, and then improving the user experience.

[0040] In some optional embodiments, when the first brightness value is greater than or equal to a preset brightness threshold, the method further includes: obtaining a standard light leakage value corresponding to white from a preset calibration data set; determining a second actual light leakage value based on the standard light leakage value corresponding to white and the backlight brightness ratio; and determining the difference between the first brightness value and the second actual light leakage value as the target brightness value.

[0041] Exemplarily, under high brightness, the pixel color of the preset area has little effect on the actual light perception of the display screen and hardly affects the user experience. Therefore, when the first brightness value is greater than or equal to the preset brightness threshold, the effect of the pixel color on the leakage brightness can be directly ignored, and only the effect of the actual brightness of the display screen on the leakage brightness can be considered. Specifically, after obtaining the first brightness value collected by the light sensor and the second brightness value of the display screen, the standard light leakage value corresponding to white can be directly obtained from the preset calibration data set. Then, after the ratio of the brightness level to the preset maximum brightness level is determined as the backlight brightness ratio, the second actual light leakage value can be determined by multiplying the standard light leakage value corresponding to white and the backlight brightness ratio; finally, the difference between the first brightness value and the second actual light leakage value is determined as the target brightness value.

[0042] The method for determining ambient brightness provided in the present embodiment does not need to consider the influence of the pixel color in the preset area on the leakage brightness when the first brightness value is greater than or equal to the preset brightness threshold. The second actual light leakage value is directly determined based on the product of the standard light leakage value corresponding to white and the backlight brightness ratio, and the difference between the first brightness value and the second actual light leakage value is determined as the target brightness value. This process does not need to obtain the standard light leakage value corresponding to the pixel color in the preset area, thereby reducing the amount of calculation and improving the calculation efficiency while ensuring the accuracy of the ambient brightness.

[0043] In this embodiment, a method for determining ambient brightness is provided, and a specific limitation is made on the case where the standard light leakage value corresponding to the pixel color does not exist in the preset calibration data set, such as Figure 2 As shown, the steps include:

[0044] S201, determining whether there is a standard light leakage value corresponding to a target color in a preset calibration data set, where the target color is a color belonging to the same color system as the pixel color.

[0045] Specifically, when there is only one pixel color in the preset area and the standard light leakage value corresponding to the pixel color does not exist in the preset calibration data set, at least one target color belonging to the same color system as the pixel color can be found in the color wheel, and it is determined whether there is a standard light leakage value corresponding to the target color in the preset calibration data set. In the following, the pixel color corresponding to the standard light leakage value that does not exist in the preset calibration data set is determined as the missing pixel color.

[0046] When there are multiple pixel colors in the preset area and the standard light leakage values ​​corresponding to at least two of the multiple pixel colors do not exist in the preset calibration data set, the target color belonging to the same color system as each missing pixel color is searched from the color wheel respectively, and it is determined whether there is a standard light leakage value corresponding to the target color in the preset calibration data set.

[0047] In an optional embodiment, when there is no standard light leakage value corresponding to the target color in the preset calibration data set, the standard light leakage value corresponding to white and the standard light leakage value corresponding to black are obtained from the preset calibration data set; a third average light leakage value is calculated based on the standard light leakage value corresponding to white and the standard light leakage value corresponding to black; and the third average light leakage value is determined as the standard light leakage value of the pixel color.

[0048] Exemplarily, if the standard light leakage value corresponding to the target color does not exist in the preset calibration data set, it means that the standard light leakage value corresponding to the missing pixel color cannot be estimated using the standard light leakage value of the target color of the same color system. At this time, the standard light leakage value Lux-White corresponding to white and the standard light leakage value Lux-Black corresponding to black can be obtained from the preset calibration data set, and then the standard light leakage value corresponding to white and the standard light leakage value corresponding to black are used to estimate the standard light leakage value corresponding to the missing pixel color. The specific estimation method is to calculate the third average light leakage value according to the standard light leakage value corresponding to white and the standard light leakage value corresponding to black, that is, the third average light leakage value = (Lux-White + Lux-Black) / 2, and determine the calculated third average light leakage value as the standard light leakage value of the pixel color. In still other examples, the third average light leakage value may also be obtained by setting weights for Lux-White and Lux-Black respectively according to the proximity of the missing pixel color to white and black in the hue wheel, and recalculating the third average light leakage value by combining the weights, Lux-White and Lux-Black. In this embodiment, the third average light leakage value = (α·Lux-White+β·Lux-Black) / 2.

[0049] S202: When there is a standard light leakage value corresponding to a target color in the preset calibration data set, directly determine the standard light leakage value corresponding to the target color as the standard light leakage value of the pixel color.

[0050] Specifically, when there are multiple target colors belonging to the same color system as the missing pixel color, but there is only a standard light leakage value corresponding to one of the target colors in the preset calibration data set, the standard light leakage value corresponding to the target color can be directly determined as the standard light leakage value of the pixel color.

[0051] S203, when there are multiple standard light leakage values ​​corresponding to the target colors in the preset calibration data set, a second average light leakage value is calculated according to the standard light leakage values ​​corresponding to all the target colors, and the second average light leakage value is determined as the standard light leakage value of the pixel color.

[0052] Specifically, when there are multiple target colors that belong to the same color system as the missing pixel color, and there are standard light leakage values ​​corresponding to at least two of the multiple target colors in the preset calibration data set, the average value of the standard light leakage values ​​corresponding to all target colors, that is, the second average light leakage value, can be calculated, and the second average light leakage value can be determined as the standard light leakage value of the pixel color.

[0053] The method for determining ambient brightness provided in this embodiment, when the standard light leakage value corresponding to the pixel color does not exist in the preset calibration data set, uses the standard light leakage value of the target color belonging to the same color system as the missing pixel color to estimate the standard light leakage value of the missing pixel color, thereby improving the acquisition efficiency and ensuring the accuracy of the data.

[0068] In some optional embodiments, the device further comprises:

[0071] This embodiment combines the self-luminous characteristics of the OLED screen. In the process of determining the first actual light leakage value, not only the influence of the actual brightness of the display screen on the leakage brightness is considered, but also the influence of the pixel color of the preset area of ​​the display screen on the leakage brightness is considered, thereby improving the accuracy of the target brightness value and further improving the user experience.
