[0023] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] At present, when a terminal device equipped with a display screen displays an image under strong light, it is difficult to clearly display the content in the image, and the dark detail information in the image will be lost, thereby reducing the display efficiency of the image.

[0026] Figure 1 The flowchart of the image display method of one embodiment of the present disclosure is as follows. It should be noted that the image display method of the present embodiment can be applied to an image display device, and the device can be configured in an electronic device so that the electronic device can perform an image display function.

[0027] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0028] In addition, the image display device of this embodiment can be set in the display screen of the electronic device; or a component in the electronic device that communicates with the display screen and can control the display screen, such as a controller, etc. The following embodiments are described by taking the execution subject as an electronic device as an example.

[0029] like Figure 1 As shown, the method comprises the following steps:

[0030] Step 101 , when the current ambient light illumination is greater than or equal to an illumination threshold, the life value of the electroluminescent device EL on the display screen is determined according to the current average grayscale of the current displayed image and the current backlight brightness of the display screen.

[0031] In an embodiment of the present disclosure, before step 101, the electronic device may perform the following process: obtain a currently displayed image on the display screen; obtain the current ambient light illumination and the current backlight brightness of the display screen; determine a grayscale histogram of the currently displayed image; determine a current average grayscale of the currently displayed image in combination with the grayscale histogram; and determine whether the current ambient light illumination is greater than or equal to an illumination threshold.

[0032] Among them, the electronic device may be provided with an ambient light sensor for collecting environmental parameters, such as the current ambient light illumination. The electronic device may interact with the ambient light sensor to obtain the current ambient light illumination collected by the ambient light sensor. Among them, the ambient light illumination refers to the illumination of the ambient light. Illuminance refers to the luminous flux of visible light received per unit area, which is used to indicate the intensity of light and the degree of illumination of the surface area of ​​an object. The unit of illumination is lux (Lux or lx).

[0033] Among them, the current backlight brightness can be the backlight brightness of the display screen of the electronic device at the current time point. Backlight brightness refers to the brightness of the backlight, that is, the display brightness value (display brightness value, dbv) of the backlight. The electronic device may be provided with a backlight controller, and the backlight controller may control the display brightness value of the backlight, and obtain the display brightness value of the backlight, etc. The electronic device may interact with the backlight controller to obtain the display brightness value of the backlight as the current backlight brightness.

[0034] The grayscale histogram may include the number of pixels having each grayscale in the currently displayed image; and weighted averaging is performed on each grayscale according to the number of pixels of each grayscale to obtain the current average grayscale of the currently displayed image.

[0035] Each pixel in the currently displayed image has a grayscale. For each pixel, the grayscale of the pixel can be determined according to the grayscale value of the pixel. That is, each grayscale corresponds to a grayscale value range; the grayscale corresponding to the grayscale value range to which the grayscale value of the pixel belongs is used as the grayscale of the pixel. The total number of grayscales, for example, 128, 256, etc., can be set according to actual needs. Taking the grayscale of a pixel as 1 as an example, the corresponding grayscale value range can be, for example, [0, 1) and the like.

[0036] In the embodiments of the present disclosure, the display screen may be a display screen with a pixel-level contrast adjustment function, such as a sunlight screen, etc., which can drive each individual pixel to be dynamically adjusted in real time and can realize a low grayscale enhancement processing function.

[0037] In the embodiment of the present disclosure, the process of the electronic device executing step 101 may, for example, be that when the current ambient light illumination is greater than or equal to the illumination threshold, the current average grayscale and the current backlight brightness are input into the correspondence model, and the life value output by the correspondence model is obtained, wherein the correspondence model is generated based on the actual correspondence between the average grayscale, the backlight brightness and the EL life value.

[0038] The corresponding relationship model can be obtained by measuring multiple display screens for electronic devices or other devices. For example, for a display screen, the backlight brightness of the display screen is set to a value, and the average grayscale of the image displayed on the display screen is set to a value, and the above state is maintained until the life of the display screen ends, that is, the corresponding relationship between an average grayscale, a backlight brightness and an electroluminescent device (EL) life value can be obtained. Repeat the above process to obtain the above corresponding relationship model.

[0039] The corresponding relationship model may be, for example, as shown in the following formula (1).

[0040] f(x,y)=a*x n +b*y n +c*x n-1 +d*y n-1 ......+e+g (1)

[0041] Among them, f represents the EL life value; x represents the average grayscale; y represents the backlight brightness; a, b, c, d, e, and g represent constants.

[0042] Step 102 : When the life value is less than or equal to the life threshold, low gray scale enhancement processing is performed on the current display image to obtain an adjusted display image.

[0043] The low grayscale may refer to a grayscale that is less than or equal to a grayscale threshold.

[0044] In the embodiment of the present disclosure, the electronic device may further perform the following process: when the life value is greater than the life threshold, the current backlight brightness is enhanced to obtain an adjusted display image.

[0045] The process of improving the current backlight brightness of the electronic device may be, for example, obtaining a target backlight brightness corresponding to the current ambient light illumination; and improving the current backlight brightness to the target backlight brightness to obtain an adjusted display image.

[0046] After the current backlight brightness is increased to the target backlight brightness, the grayscale of each pixel in the adjusted display image is increased. The ambient light illumination may be positively correlated with the backlight brightness; the greater the ambient light illumination, the greater the backlight brightness.

[0047] In the image display method of the disclosed embodiment, the life value of the electroluminescent device EL on the display screen is determined according to the current average grayscale of the currently displayed image and the current backlight brightness of the display screen when the current ambient light illuminance is greater than or equal to the illuminance threshold; when the life value is less than or equal to the life threshold, the low grayscale boost processing is performed on the currently displayed image to obtain an adjusted display image, so that the grayscale adjustment processing is performed on the currently displayed image while ensuring the life of the electroluminescent device EL, so as to avoid the loss of dark detail information in the image, clearly display the content in the image, and thus improve the display efficiency of the image.

[0048] Figure 2 This is a flow chart of an image display method according to another embodiment of the present disclosure. It should be noted that the image display method according to this embodiment can be applied to an image display device, which can be configured in an electronic device so that the electronic device can perform an image display function.

[0049] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0050] In addition, the image display device of this embodiment can be set in the display screen of the electronic device; or a component in the electronic device that communicates with the display screen and can control the display screen, such as a controller, etc. The following embodiments are described by taking the execution subject as an electronic device as an example.

[0051] like Figure 2 As shown, the method comprises the following steps:

[0052] Step 201 : when the current ambient light illumination is greater than or equal to the illumination threshold, the life value of the electroluminescent device EL on the display screen is determined according to the current average grayscale of the current displayed image and the current backlight brightness of the display screen.

[0053] Step 202, when the life value is less than or equal to the life threshold, query the grayscale boost curve according to the current average grayscale and the current backlight brightness to obtain the current grayscale boost value; wherein the grayscale boost curve includes the grayscale boost value corresponding to the average grayscale and the backlight brightness when the EL life is intact.

[0054] In the disclosed embodiment, before step 202, the electronic device may obtain a grayscale boost curve. The process of the electronic device obtaining the grayscale boost curve may be, for example, obtaining a correspondence model between the average grayscale, the backlight brightness, and the EL life value; obtaining the average grayscale and the backlight brightness corresponding to the first EL life value in the correspondence model; wherein the first EL life value is greater than or equal to the life threshold; for each first EL life value, obtaining a display image having an average grayscale corresponding to the first EL life value; performing low grayscale boost processing on the display image until the EL life value is less than the life threshold; obtaining a grayscale boost value of the display image; establishing a correspondence between the grayscale boost value, the average grayscale corresponding to the first EL life value, and the backlight brightness corresponding to the first EL life value; and determining to obtain a grayscale boost curve based on a plurality of the above correspondences.

[0055] In the embodiment of the present disclosure, the process of the electronic device executing step 202 may, for example, be to query the grayscale boost curve according to the current average grayscale and the current backlight brightness to obtain the target point in the grayscale boost curve; the grayscale difference between the average grayscale at the target point and the current average grayscale is less than or equal to the grayscale difference threshold, and the brightness difference between the backlight brightness at the target point and the current backlight brightness is less than or equal to the brightness difference threshold; and the grayscale boost value at the target point is determined as the current grayscale boost value.

[0056] Each point in the grayscale enhancement curve corresponds to a grayscale enhancement value, an average grayscale, and backlight brightness. In other words, a set of grayscale enhancement values, average grayscale, and backlight brightness determines a point in the grayscale enhancement curve.

[0057] Step 203 , performing low grayscale enhancement processing on the current display image according to the current grayscale enhancement value to obtain an adjusted display image.

[0058] In the disclosed embodiment, the process of the electronic device executing step 203 may, for example, be as follows: adjusting the original color model of the currently displayed image to the HSV color model to obtain the currently displayed image under the HSV color model; obtaining a low grayscale area in the currently displayed image under the HSV color model; the grayscale of the pixel in the low grayscale area is less than or equal to the grayscale threshold; for each pixel in the low grayscale area, performing grayscale enhancement processing on the pixel according to the current grayscale enhancement value to obtain a processed displayed image under the HSV color model; adjusting the HSV color model of the processed displayed image to the original color model to obtain an adjusted displayed image.

[0059] The original color model and the HSV color model may be the same or different. The original color model may be, for example, an HSV color model, an RGB color model, a CMYK color model, a Lab color model, an indexed color model, a bitmap color model, etc., which may be set according to actual needs. When the original color model and the HSV color model are different, the electronic device may perform the above steps to obtain an adjusted display image.

[0060] Among them, when the original color model is the same as the HSV color model, the process of the electronic device executing step 203 can, for example, be to obtain a low grayscale area in the current display image under the HSV color model; the grayscale of the pixel in the low grayscale area is less than or equal to the grayscale threshold; for each pixel in the low grayscale area, the grayscale of the pixel is enhanced according to the current grayscale enhancement value to obtain a processed display image under the HSV color model; and the processed display image under the HSV color model is used as the adjusted display image.

[0061] In the HSV color model, the color parameters of each pixel may include: hue (Hue, H), saturation (Saturation, S), and brightness (Value, V).

[0062] It should be noted that the detailed description of step 201 can be found in Figure 1 Step 101 in the illustrated embodiment will not be described in detail here.

[0063] In the image display method of the disclosed embodiment, the life value of the electroluminescent device EL on the display screen is determined according to the current average grayscale of the currently displayed image and the current backlight brightness of the display screen when the current ambient light illumination is greater than or equal to the illumination threshold; when the life value is less than or equal to the life threshold, the grayscale boost curve is queried according to the current average grayscale and the current backlight brightness to obtain the current grayscale boost value; wherein the grayscale boost curve includes the grayscale boost values ​​corresponding to the average grayscale and the backlight brightness when the EL life is intact; according to the current grayscale boost value, the currently displayed image is subjected to low grayscale boost processing to obtain an adjusted display image, thereby performing grayscale adjustment processing on the currently displayed image while ensuring the life of the electroluminescent device EL, avoiding the loss of dark detail information in the image, being able to clearly display the content in the image, and thereby improving the display efficiency of the image.

[0064] The following examples are used to illustrate this. Figure 3 As shown in FIG. 1 , a schematic diagram of the framework of the image display method is shown. Figure 3The method comprises the following steps: (1) determining whether the ambient light LUX (ambient light illumination) is greater than a set threshold value (illuminance threshold); if so, executing steps (2) and (3); if not, stopping executing the subsequent steps. (2) testing the corresponding relationship (binary N-order relationship) between the life of the EL device of the screen (EL life value) and the average grayscale of the picture (average grayscale) and the backlight DBV (backlight brightness); and then executing step (6). (3) acquiring an image data stream (a video containing the currently displayed image). (4) reading the histogram of the current frame image (the grayscale histogram of the currently displayed image), and then obtaining the average grayscale. (5) bringing in the corresponding relationship, determining the influence of the current picture (currently displayed image) and the backlight on the EL device. (6) determining whether the life of the EL device is affected (determining whether the obtained life value is less than or equal to the life threshold in combination with the corresponding relationship); if so, executing step (7); if not, executing step (8). (7) increasing the backlight DBV according to the ambient light. (8) fixing the DBV, increasing the grayscale of the low grayscale part of the picture, and enhancing readability.

[0065] Among them, step (8) can specifically include the following steps: (8.1) RSB color model is converted to HSV color model. (8.2) Keeping H unchanged, mapping the V value to raise the low grayscale value. (8.3) HSV color model is converted to RGB color model.
