[0028] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application with reference to the drawings in the embodiments of the present application. The following embodiments are used to explain the present application, but are not used to limit the scope of the present application.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing the embodiments of the present application only and is not intended to limit the present application.

[0030] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments, but it is understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0031] It should be noted that the terms "first", "second", "third" in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific order of the objects. Understandably, "first", "second", "third" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0032] In order to make the image displayed by the terminal device have better effect, it is usually necessary to improve the dynamic range of the image, so as to increase the color range of the pixel points of the displayed image, increase the contrast between different layers, and achieve better display effect.

[0033] The dynamic range of the image refers to the ratio between the maximum signal value and the minimum signal value in the image. For a digital image, it is usually represented as the ratio of the maximum pixel value and the minimum pixel value. For example, in an 8-bit gray image, the pixel value of each color channel ranges from 0 to 255. If the pixel value in the image ranges from 0 (darkest) to 255 (brightest), the dynamic range is 255:1. Accordingly, if the bit is increased, the dynamic range will also increase; if the bit is reduced, the dynamic range will also decrease.

[0034] In the related art, in order to realize the dynamic range adjustment of the image, the gray image superposition method is adopted.

[0035] In an example, an SDR (Standard Dynamic Range) image can be obtained by shooting. In addition, a gray layer can be set to mark the area where the brightness needs to be improved and the area where the brightness does not need to be improved. In addition, the gray layer can store related parameters to indicate the superposition between the SDR image and the gray layer.

[0036] The high dynamic range image can be obtained by superimposing two images. The high dynamic range image can include a main image of an 8-bit standard dynamic range image and a gain image. The gain image stores additional high dynamic range gain mapping data. The gain mapping essentially accurately marks the brightness of each pixel point, so that the details of the image smoothly transition between highlights and dark parts, avoiding the problems of overexposure or dark distortion. However, this method has a complex calculation process, which can easily cause device lag.

[0037] In addition, due to the superposition process of the gray image, the high dynamic range image obtained by the process can only be used for static pictures and cannot be used for dynamic pictures. If there is a dynamic picture that needs high dynamic range display, the above process cannot be implemented.

[0038] And, since in the process of image superimposition, it is necessary to superimpose with a gray image, in order to ensure the overall image brightness, the brightness of the SDR image is usually adjusted to be low, which may cause the user to exist in the process of screenshot that the brightness of the image obtained by the screenshot and the actual displayed image is not the same, and the screenshot exists obvious darkening, and the display effect is not always the same.

[0039] The difference between the high dynamic range image and the standard dynamic range image provided in the embodiment of the application will be explained below through the difference of two specific images.

[0040] Figure 1 For the dynamic range adjustment provided in the embodiment of the application, please refer to Figure 1 , Figure 1 The left subgraph is a standard dynamic range image, that is, the above-mentioned SDR image, and the right subgraph is an HDR image (High Dynamic Range, high dynamic range image).

[0041] Among them, it can be seen that there is a higher contrast between the clouds in the sky and the photographed scenery in the right image, and the display effect of the whole image is better.

[0042] It should be noted that in this scenario, the above two images can be displayed in an electronic device, wherein the electronic device can include but is not limited to a mobile phone, a wearable device (such as a smart watch, a smart bracelet, smart glasses, etc.), a tablet computer, a notebook computer, a vehicle terminal, a PC (Personal Computer, personal computer), etc. The function realized by the method can be realized by calling program code by the processor in the electronic device, and of course the program code can be saved in the computer storage medium, so the electronic device at least includes a processor and a storage medium.

[0043] As explained before, in the related art, there is a complex loading process in the calculation process, which is easy to cause the device to be stuck. In order to solve the problems existing in the related art as above, an image display method is provided in the embodiment of the application, and the actual implementation process of the method will be explained below.

[0044] Figure 2 For the flowchart of the image display method provided in the embodiment of the application, please refer to Figure 2 , the image display method comprises:

[0045] S210: generating a second target image under the condition of adjusting the brightness range of the first target image.

[0046] It should be noted that the execution subject of the method can be the above-mentioned electronic device.

[0047] The first target image can be any image that needs to be adjusted in luminance range, for example, an image captured by an electronic device, or an image stored in the electronic device. Without specific limitation, the first target image can be any image stored in the media library of the electronic device, or a desktop wallpaper of the electronic device, etc.

[0048] In an embodiment, the first target image can be a static image or a dynamic image, without specific limitation.

[0049] In the case where the first target image needs to be adjusted, the luminance range of the first target image can be adjusted, for example, in the case where the display effect of the first target image needs to be improved, or in the case where a part of the first target image needs to be highlighted, the luminance range of the first target image can be adjusted.

[0050] In the process of adjusting the luminance range of the first target image, a second target image can be generated, wherein the second target image includes at least one element in the first target image.

[0051] In an embodiment, the second target image can be a copy of a part of the first target image, for example, a copy of a part of the first target image that is cropped from the first target image; or the second target image can also be a new image composed of elements included in the first target image, for example, a graphic composed of part of the control elements in the first target image.

[0052] For example, the first target image can include multiple elements, which can refer to the content included in a layer of the first target image, for example, taking the first target image as a desktop of an electronic device, the desktop can be composed of a desktop wallpaper and various controls displayed on the desktop, wherein the desktop wallpaper and the various controls on the desktop can each be an element that composes the first target image, any one or more of the elements can be combined to obtain the second target image, for example, assuming that the first target image includes a combination of a desktop wallpaper and a clock control, the second target image can be an additional image composed of the clock control.

[0053] S220: adjust the picture content luminance range of the first target image, and the backlight luminance range of the first target image and the second target image.

[0054] It should be noted that after the first target image and the second target image are obtained, the luminance range of the two target images can be adjusted.

[0055] The luminance range that can be adjusted includes the picture content luminance range and the backlight luminance range.

[0056] In an embodiment, the picture content luminance range refers to the actual luminance range of the displayed content on the display device. It depends on the pixel values of the displayed content and the display capability of the display device. For example, on a display device, if the displayed content is pure white, the picture content luminance will be high; if the displayed content is pure black, the picture content luminance will be low.

[0057] The backlight luminance range refers to the luminance range of the backlight of the display device. The backlight is the light source inside the display device for illuminating the displayed content. In a liquid crystal display (LCD), the backlight is usually composed of LEDs (light-emitting diodes) or CCFLs (cold cathode fluorescent lamps).

[0058] The luminance of the image seen by the user can be composed of the picture content luminance and the backlight luminance, and in the process of luminance range adjustment, the two luminance ranges can be adjusted synchronously.

[0059] It should be noted that for the first target image, the adjustment of the picture content luminance range and the adjustment of the backlight luminance range can be performed respectively; for the second target image, only the adjustment of the backlight luminance range can be performed.

[0060] For example, in the process of luminance range adjustment, the luminance range can be adjusted in percentage. Assuming that the initial luminance range is in the range of 0-1, if the luminance range is reduced to 80% of the original, the luminance range can be adjusted to the range of 0-0.8, so that the overall luminance range is lowered and the overall image will appear darker; on the contrary, if the luminance range is increased to 125% of the original, the luminance range can be adjusted to 0-1.25, so that the overall luminance range is increased and the overall image will appear brighter.

[0061] In which, the adjustment directions of the picture content luminance range and the backlight luminance range are opposite.

[0062] That is to say, in the process of luminance adjustment, if the picture content luminance range is increased, the backlight luminance range will be reduced; if the picture content luminance range is reduced, the backlight luminance range will be increased.

[0063] S230: display the first target image and the second target image after luminance range adjustment.

[0064] It should be noted that after the above luminance range adjustment, the first target image and the second target image can be displayed in the electronic device, in which the second target image is superimposed on the first target image.

[0065] In an embodiment, the picture content brightness range of the first target image can be reduced in the picture content brightness adjustment process, and the backlight brightness range of the first target image can be increased in the backlight brightness adjustment process, so as to ensure that the overall brightness range of the first target image remains unchanged. For the second target image, only the backlight brightness range is adjusted, so the backlight brightness range changes, so that the overall brightness range interval between the first target image and the second target image is not the same, thereby enabling the first target image and the second target image to have a certain contrast, so that the user can clearly see the difference between the first target image and the second target image when viewing the image displayed in the electronic device.

[0066] The above adjustment process only changes the image brightness range and does not involve complex image processing, so it will not cause a large amount of calculation and will not cause the electronic device to freeze.

[0067] In the image display method provided by the embodiments of the present application, the second target image including at least one element in the first target image can be generated in the case of adjusting the brightness range of the first target image. The picture content brightness range of the first target image and the backlight brightness range of the first target image and the second target image are adjusted, and the adjustment directions of the picture content brightness range and the backlight brightness range are opposite. The first target image and the second target image after brightness range adjustment are displayed, and the second target image is superimposed on the first target image. By adjusting the picture content brightness range and the backlight brightness range of the first target image and adjusting the display brightness range of the second target image, the dynamic range of the first target image and the second target image can be adjusted, so that the dynamic range of the first target image and the second target image is different, and the contrast of the first target image and the second target image can be further improved, thereby improving the display effect of the second target image. Moreover, since the processing process is only brightness range adjustment, the calculation content involved is less, and the terminal device will not freeze and other problems, so that the contrast of different layers in the image can be improved while avoiding device freezing.

[0068] The following explains one of the feasible implementation processes of adjusting the brightness range of the target image provided in the embodiments of the present application.

[0069] Figure 3 For the flowchart of the brightness range adjustment provided in the embodiments of the present application, please refer to Figure 3 , adjusting the picture content brightness range of the first target image and the backlight brightness range of the first target image and the second target image comprises:

[0070] S310: Reduce the picture content brightness range of the first target image according to the first target adjustment parameter.

[0071] It should be noted that in the process of adjusting the luminance range, the adjustment of the picture content luminance range and the backlight luminance range is opposite, so the picture content luminance range can be increased and the backlight luminance range can be decreased, or the picture content luminance range can be decreased and the backlight luminance range can be increased.

[0072] In this embodiment, the picture content luminance range can be decreased and the backlight luminance range can be increased.

[0073] It should be noted that the aforementioned adjustment of the luminance range is to expand or reduce the original luminance range by a percentage, wherein the first target adjustment parameter can be a parameter for adjusting the luminance range, and can be a percentage coefficient, for example: if the first target adjustment parameter is between 0-1, the picture content luminance range can be decreased; if the first target adjustment parameter is greater than 1, the picture content luminance range can be increased.

[0074] In this embodiment, the first target adjustment parameter can be between 0-1, for example, it can be 80%.

[0075] Suppose the initial range of the picture content luminance can be in the interval of 0-1, if the first target adjustment parameter is 80%, the adjusted picture content luminance range can be 0-0.8, that is, the picture content luminance is reduced as a whole.

[0076] It should be noted that in the process of adjusting the picture content luminance range, the adjustment can be performed on the first target image.

[0077] S320: Increase the backlight luminance range of the first target image and the second target image according to the second target adjustment parameter.

[0078] The second target adjustment parameter can be a parameter for adjusting the luminance range, and can be a percentage coefficient, for example: if the second target adjustment parameter is between 0-1, the backlight luminance range can be decreased; if the second target adjustment parameter is greater than 1, the backlight luminance range can be increased.

[0079] In this embodiment, the second target adjustment parameter can be greater than 1, for example, it can be 125%.

[0080] Suppose the initial range of the backlight luminance can be in the interval of 0-1, if the second target adjustment parameter is 125%, the adjusted backlight luminance range can be 0-1.25, that is, the backlight luminance is increased as a whole.

[0081] It should be noted that in the process of adjusting the backlight luminance range, the adjustment can be performed on the first target image and the second target image.

[0082] The first target adjustment parameter and the second target adjustment parameter are two preset adjustment ratios which are reciprocal to each other.

[0083] It should be noted that, in order to ensure that the overall brightness of the first target image does not change after the adjustment of the backlight brightness range and the picture content brightness range, the first target adjustment parameter and the second target adjustment parameter can be set as two preset adjustment ratios which are reciprocal to each other, for example, if the first target adjustment parameter is 0.8, the second target parameter adjustment parameter can be 1.25; correspondingly, if the first target adjustment parameter is 0.5, the second target parameter adjustment parameter can be 2, which is not limited here.

[0084] For the first target image, since the backlight brightness range increases and the picture content brightness range decreases, the overall brightness range does not change; and for the second target image, since the backlight brightness range increases, the dynamic display range of brightness changes from 0-1 to 0-1.25, thus increasing the dynamic range in the entire interval of 1-1.25, which can provide a dynamic range exceeding 8 bits for an 8-bit grayscale image.

[0085] For different electronic devices, the process of implementing the above steps S310-S320 can have certain differences, since the adjustment of the picture content brightness range and the adjustment of the backlight brightness range are usually performed synchronously, there is a certain synchronization requirement for the display of the electronic device, and the backlight of the LCD screen cannot be synchronized because the picture content is effective on the screen following the TE signal (Tearing Effect Signal, tearing effect signal) and is effective on the falling edge of the TE signal, which may have a problem of being unable to synchronize.

[0086] In order to solve this problem, the LCD screen can be specially processed, the system backlight curve is increased by 1.25 times as a whole, and the picture content of the system is decreased by 0.8 times under the full scene full brightness, only the second target image is identified and the brightness value is set to 1, so that the transition of the brightening of the backlight and the darkening of the picture content in the system switching process is not required, and the synchronization of the two is not required.

[0087] In the image display method provided by the embodiment, the picture content luminance range of the first target image can be reduced according to the first target adjustment parameter, and the backlight luminance range of the first target image and the second target image can be increased according to the second target adjustment parameter. In the process of adjusting the luminance range of the first target image and the second target image, since the first target adjustment parameter and the second target adjustment parameter are two preset adjustment ratios that are inverses of each other, the overall luminance of the first target image can be ensured unchanged, and the second target image is adjusted in the backlight luminance range, so that there is an obvious luminance range difference between the first target image and the second target image, the contrast between the two can be highlighted, and the display effect of the image can be improved.

[0088] The following will specifically explain one of the feasible implementation processes of adjusting the picture content luminance range provided in the embodiment.

[0089] Figure 4 For the flowchart of adjusting the picture content luminance range provided in the embodiment, please refer to Figure 4 The picture content luminance range of the first target image is reduced according to the first target adjustment parameter, including:

[0090] S410: determining a target adjustment range of picture content luminance according to the first target adjustment parameter.

[0091] The target adjustment range of picture content luminance is smaller than the current range of picture content luminance.

[0092] It should be noted that the current range of picture content luminance can be the range of picture content luminance of the image currently displayed by the electronic device, and in the absence of additional adjustment, the range can be the initial range, for example, the range of luminance 0-1 explained above.

[0093] The target adjustment range of picture content luminance can be a range calculated based on the first target adjustment parameter, for example, the range of luminance 0-0.8 explained above, wherein the upper limit of the range can be calculated based on the first target adjustment parameter.

[0094] S420: mapping the picture content luminance of the first target image from the current range to the target adjustment range.

[0095] It should be noted that in the process of luminance mapping, the luminance can be calculated according to the proportion, so as to realize the corresponding mapping.

[0096] In an embodiment, the luminance value of each pixel point can be reduced based on the first target adjustment parameter in a proportional mapping manner to realize mapping, thereby realizing mapping of the luminance range 0-1 to 0-0.8. For example, the luminance value of 1 is mapped to 0.8, and the luminance value of 0.5 is mapped to 0.4.

[0097] In another embodiment, a normalized mapping manner can also be used, for example, the pixel points of the picture content luminance in the range of 0-0.8 are kept unchanged, and the pixel points of the picture content luminance in the range of 0.8-1 are changed to the pixel points of 0.8 picture content luminance.

[0098] Regardless of any one of the above two mapping manners, the picture content luminance of the first target image can be mapped from the current range to the target adjustment range, thereby realizing adjustment of the picture content luminance range of the first target image.

[0099] In the image display method provided in the embodiments of the present application, the target adjustment range of the picture content luminance can be determined according to the first target adjustment parameter; and the picture content luminance of the first target image is mapped from the current range to the target adjustment range. The mapping of the picture content luminance of the first target image is realized by determining the target adjustment range, thereby realizing adjustment of the picture content luminance range of the first target image, and the accuracy and rationality of the luminance range adjustment can be ensured.

[0100] The following explains one of the feasible implementation processes of adjusting the backlight luminance range provided in the embodiments of the present application.

[0101] Figure 5 For the flowchart of the backlight luminance range adjustment provided in the embodiments of the present application, please refer to Figure 5 The backlight luminance range of the first target image and the second target image is increased according to the second target adjustment parameter, including:

[0102] S510: determining the target adjustment range of the backlight luminance according to the second target adjustment parameter.

[0103] The target adjustment range of the backlight luminance is greater than the current range of the backlight luminance.

[0104] It should be noted that the current range of the backlight luminance can be the range of the backlight luminance of the image currently displayed by the electronic device, and in the absence of additional adjustment, the range can be the initial range, for example, the luminance range of 0-1 explained above.

[0105] The target adjustment range of the backlight brightness can be a calculated range based on the second target adjustment parameter, for example, the range of 0-1.25 of the aforementioned explained brightness, wherein the upper limit of the range can be calculated based on the second target adjustment parameter.

[0106] S520: mapping the backlight brightness of the first target image and the second target image from the current range to the target adjustment range.

[0107] It should be noted that in the process of brightness mapping, the brightness can be calculated in proportion, so as to realize the corresponding mapping.

[0108] In an embodiment, the brightness value of each pixel point can be expanded based on the second target adjustment parameter to realize the mapping by using the equal proportion mapping, so as to realize the mapping of the brightness range 0-1 to 0-1.25. For example, the brightness value of 1 is mapped to 1.25, and the brightness value of 0.8 is mapped to 1.

[0109] The backlight brightness of the first target image and the second target image can be mapped from the current range to the target adjustment range, so as to realize the adjustment of the backlight brightness range of the first target image and the second target image.

[0110] In the image display method provided by the embodiment, the target adjustment range of the backlight brightness can be determined according to the second target adjustment parameter; the backlight brightness of the first target image and the second target image is mapped from the current range to the target adjustment range. The mapping of the backlight brightness of the first target image and the second target image is realized by determining the target adjustment range, so as to realize the adjustment of the backlight brightness range of the first target image and the second target image, and the accuracy and rationality of the brightness range adjustment can be ensured.

[0111] In an embodiment, the picture content brightness range of the first target image is reduced according to the first target adjustment parameter, including: reducing the picture content brightness range of all regions of the first target image according to the first target adjustment parameter; or reducing the picture content brightness range of a target region of the first target image according to the first target adjustment parameter, the target region being a region of the first target image except at least one element corresponding to the second target image.

[0112] It should be noted that in the process of adjusting the picture content brightness range of the first target image, the adjustment can be performed on all regions of the first target image, or can be performed on a part of the regions that can be seen by the user.

[0113] For example, the luminance of each pixel in the first target image can be adjusted according to the first target adjustment parameter to reduce the overall picture content luminance range.

[0114] During the adjustment, the first target image is displayed on the second target image, that is, the second target image covers part of the first target image, and this part of the first target image is the area composed of the elements of the second target image. For example, the first target image is a desktop, and the second target image is a clock control on the desktop. The clock control originally displayed in the first target image is covered by the second target image. Therefore, during the picture content luminance range adjustment, the luminance range of this part of the picture can not be adjusted, that is, only the area of the first target image except the part covered by the second target image is adjusted in the picture content luminance range.

[0115] In the image display method provided by the embodiment of the present application, the picture content luminance range of the entire first target image can be reduced according to the first target adjustment parameter, or the picture content luminance range of the target area of the first target image can be reduced according to the first target adjustment parameter. The target area is an area of the first target image except at least one element corresponding to the second target image. During the picture content luminance range adjustment, the picture content luminance range of the entire area or the target area can be adjusted according to actual needs, improving the applicability of the image display method.

[0116] The following explains another possible implementation process of adjusting the luminance range of the target image provided in the embodiment of the present application.

[0117] Figure 6 For another flowchart of the luminance range adjustment provided in the embodiment of the present application, please refer to Figure 6 , adjusting the picture content luminance range of the first target image and the backlight luminance range of the first target image and the second target image, comprising:

[0118] S610: increasing the picture content luminance range of the first target image according to the third target adjustment parameter.

[0119] It should be noted that during the luminance range adjustment, the adjustment of the picture content luminance range and the backlight luminance range is opposite, so the picture content luminance range can be increased and the backlight luminance range can be reduced, or the picture content luminance range can be reduced and the backlight luminance range can be increased.

[0120] In this embodiment, the picture content luminance range can be increased and the backlight luminance range can be reduced.

[0121] It should be noted that the aforementioned has explained that the adjustment of the luminance range is to expand or reduce the original luminance range according to a percentage, wherein the third target adjustment parameter can be a parameter for adjusting the luminance range, and can be a percentage coefficient, for example: if the third target adjustment parameter is between 0-1, the luminance range of the picture content can be reduced; if the third target adjustment parameter is greater than 1, the luminance range of the picture content can be increased.

[0122] In this embodiment, the third target adjustment parameter can be greater than 1, for example, can be 125%.

[0123] Suppose the initial range of the picture content luminance can be in the interval of 0-1, if the third target adjustment parameter is 125%, the adjusted picture content luminance range can be 0-1.25, that is, the picture content luminance is overall increased.

[0124] It should be noted that in the process of adjusting the luminance range of the picture content, the adjustment can be performed on the first target image.

[0125] S620: Reduce the backlight luminance range of the first target image and the second target image according to the fourth target adjustment parameter.

[0126] The fourth target adjustment parameter can be a parameter for adjusting the luminance range, and can be a percentage coefficient, for example: if the fourth target adjustment parameter is between 0-1, the backlight luminance range can be reduced; if the fourth target adjustment parameter is greater than 1, the backlight luminance range can be increased.

[0127] In this embodiment, the fourth target adjustment parameter can be between 0-1, for example, can be 80%.

[0128] Suppose the initial range of the backlight luminance can be in the interval of 0-1, if the fourth target adjustment parameter is 80%, the adjusted backlight luminance range can be 0-0.8, that is, the backlight luminance is overall reduced.

[0129] It should be noted that in the process of adjusting the backlight luminance range, the adjustment can be performed on the first target image and the second target image.

[0130] The third target adjustment parameter and the fourth target adjustment parameter are two preset adjustment ratios which are inverses of each other.

[0131] It should be noted that, in order to ensure that the overall brightness of the first target image does not change after the adjustment of the backlight brightness range and the picture content brightness range, the third target adjustment parameter and the fourth target adjustment parameter can be set as two preset adjustment parameters which are reciprocal to each other, for example, if the third target adjustment parameter is 1.25, the fourth target adjustment parameter can be 0.8; correspondingly, if the third target adjustment parameter is 2, the fourth target adjustment parameter can be 0.5, which is not limited specifically herein.

[0132] In an embodiment, Figure 6 The implementation process shown is opposite to the two implementation manners shown in Figure 3 The implementation process shown is opposite to the two implementation manners shown in Figure 3 The manner shown can be applied to a scene in which the second target image needs to be highlighted in a brighter manner. Figure 6 The manner shown can be applied to a scene in which the second target image needs to be highlighted in a darker manner, and in the actual implementation process, one of the two manners can be selected according to actual needs to adjust the brightness range.

[0133] In the image display method provided by the embodiment of the present application, the picture content brightness range of the first target image can be increased according to the third target adjustment parameter, and the backlight brightness range of the first target image and the second target image can be reduced according to the fourth target adjustment parameter. In the process of adjusting the brightness range of the first target image and the second target image, since the third target adjustment parameter and the fourth target adjustment parameter are two preset adjustment parameters which are reciprocal to each other, the overall brightness of the first target image can be ensured to be unchanged, and the second target image is adjusted in the backlight brightness range, so that there is an obvious brightness range difference between the first target image and the second target image, the contrast between the two can be highlighted, and the display effect of the image can be improved.

[0134] Next, one of the feasible implementation processes for obtaining the second target image provided in the embodiment of the present application will be explained.

[0135] Figure 7 For the flowchart for generating the second target image provided in the embodiment of the present application, please refer to Figure 7 The second target image is generated, including:

[0136] S710: Obtain image information of the first target image, and determine at least one target element from the first target image based on the image information.

[0137] It should be noted that the image information of the first target image can be the file information of the media file corresponding to the image, for example, the image information of the first target image can be obtained from the source code.

[0138] The image information can include each element constituting the image. Taking the above desktop as an example, in a case where the first target image is a desktop of an electronic device, the image information can include various elements constituting the image, for example, a desktop wallpaper, each control on the desktop, and the like.

[0139] The desktop wallpaper and each control can be one of the elements, and the element can be selected according to actual display requirements. For example, if the desktop wallpaper needs to be highlighted, the desktop wallpaper can be selected as the target element; or if the time displayed on the desktop needs to be highlighted, the clock control can be selected as the target element.

[0140] It should be noted that one or more elements can be selected as the target element according to actual requirements, or all other elements in the layer in which the element is located can be selected as the target element, which is not limited specifically herein.

[0141] In an embodiment, the electronic device can provide a corresponding interface, and an application in the electronic device or a user can call the interface to select the elements, thereby obtaining the target element.

[0142] For example, for a clock application, in order to clearly display the time on the desktop, the clock application can call the interface and set the clock control as the target element, so that the second target image can be generated based on the clock control.

[0143] S720: generating a second target image based on the at least one target element.

[0144] Optionally, after the target element is selected by the above method, the second target image can be generated based on the target element. For example, the target element can be copied to obtain a new target element, and the image composed of the new target element is the second target image.

[0145] In an embodiment, if the time displayed on the desktop needs to be highlighted, the clock control can be copied to form a new image, that is, the second target image.

[0146] In the image display method provided in the embodiments of the present application, the image information of the first target image can be acquired, and at least one target element can be determined from the first target image based on the image information; and a second target image can be generated based on the at least one target element. In the method, the target element can be selected by acquiring the image information of the first target image, and then the second target image can be generated based on the target element after the at least one target element is determined, so that the second target image corresponding to the target element in the first target image can be obtained from the first target image, and the partial content of the first target image can be copied.

[0147] The following explains another possible implementation process for obtaining the second target image provided in the embodiments of the present application.

[0148] Figure 8 For another flowchart for generating the second target image provided in the embodiments of the present application, refer to Figure 8 The second target image is generated, including:

[0149] S810: Perform image recognition processing on the first target image to obtain background elements and non-background elements in the first target image.

[0150] It should be noted that in the process of image recognition on the first target image, a pre-trained neural network model can be used for recognition.

[0151] The neural network model can be a neural network model obtained by training based on sample images and recognition results of the sample images, can be a deep neural network model or a convolutional neural network model, etc., which is not specifically limited here, and a corresponding neural network model can be selected for image recognition according to actual needs.

[0152] In an embodiment, the background elements and non-background elements can be recognized from the first target image by the image recognition method, wherein the background elements can be landscape elements located at the edge of the image, such as trees, white clouds, sky, etc.; and the non-background elements can be persons, animals or other things in the middle of the image, etc., which are not specifically limited here.

[0153] In an embodiment, the first target image can be input into the above-mentioned neural network model, so as to be output based on the recognition of the neural network model, to obtain the background elements and non-background elements in the first target image.

[0154] S820: Generate the second target image based on the background elements or the non-background elements.

[0155] In an embodiment, the second target image can be generated based on the background elements or the non-background elements according to actual selection needs.

[0156] For example, a non-background element can be copied, and the copied content can be used as the second target image.

[0157] It should be noted that in actual implementation, the second target image can be generated based on the background elements or the non-background elements, which can be obtained based on user selection or image content recognition, which is not specifically limited here, and the second target image can be generated based on any of the elements.

[0158] In the image display method provided by the embodiments of the present application, image recognition processing can be performed on the first target image to obtain background elements and non-background elements in the first target image; and a second target image can be generated based on the background elements or the non-background elements. The background elements and the non-background elements can be determined from the first target image by means of neural network model recognition, and then the second target image can be generated based on any one of the elements, thereby realizing copying of part of the content of the first target image.

[0159] It should be noted that in actual implementation, any one of the following methods can be selected to generate the second target image: Figure 7 or Figure 8 For example, the image information of the first target image can be obtained first to determine whether the image includes multiple elements. If the image includes multiple elements, the method shown in Figure 7 can be used to generate the second target image. If the image does not include multiple elements, the image recognition method shown in Figure 8 can be used to generate the second target image.

[0160] The effect after the brightness range adjustment in the image display method provided by the embodiments of the present application will be explained below.

[0161] Figure 9 For the logic diagram for realizing the brightness range adjustment provided by the embodiments of the present application, please refer to the left sub-diagram in Figure 9 , Figure 9 The first target image can be the desktop of the electronic device, the second target image can be the clock control on the desktop, and the right sub-diagram can be the display image, that is, the image obtained after superimposing the first target image after the brightness range adjustment and the second target image after the brightness range adjustment.

[0162] The clock control can include time, date, weather, temperature and the like, for example, the time shown in Figure 9 may be 18:00, the date can be July 21, the weather can be rainy, and the temperature can be 26°.

[0163] By comparing the first target image and the superimposed image, it can be seen that in the first target image, the clock control is almost integrated with the white background in the first target image due to the low contrast, and the corresponding time cannot be accurately seen, so the display effect is poor. After the brightness range adjustment of the first target image and the second target image and superimposition, there is an obvious brightness difference between the clock control and the corresponding white background, and there is a certain contrast, so the corresponding time can be accurately seen, and the display effect is good.

[0164] In an embodiment, the first target image and the second target image involved in the present application can be static images or dynamic images, and the brightness adjustment is based on the corresponding image.

[0165] In addition, since the adjustment process of the first target image and the second target image only involves the adjustment of the brightness range, which is essentially the adjustment of the pixel brightness, and does not involve complex image superposition operation, the electronic device will not be stuck during the adjustment process.

[0166] In addition, since the overall brightness range of the first target image is kept unchanged, there is no case that the screenshot is obviously darkened during the screenshot process, and the consistency of the screenshot and the display content can be achieved.

[0167] It should be understood that although each step in the above flowcharts is displayed in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, at least part of the steps in the above flowcharts can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with other steps or sub-steps or stages of other steps.

[0168] Based on the foregoing embodiments, the present application provides an image display device, which includes the modules included therein and the units included in the modules, and can be implemented by a processor; of course, it can also be implemented by a specific logic circuit; in the implementation process, the processor can be a central processing unit (CPU), a microprocessor (MPU), a digital signal processor (DSP), or a field programmable gate array (FPGA), etc.

[0169] Figure 10 For the structure diagram of the image display device provided in the embodiments of the present application, please refer to Figure 10 , the image display device includes a generation module 1010, an adjustment module 1020, and a display module 1030.

[0170] The generation module 1010 is configured to generate a second target image in the case of adjusting the brightness range of a first target image, the second target image including at least one element in the first target image.

[0171] The adjusting module 1020 is configured to adjust a picture content luminance range of the first target image, and a backlight luminance range of the first target image and the second target image, and the adjusting directions of the picture content luminance range and the backlight luminance range are opposite.

[0172] The display module 1030 is configured to display the first target image and the second target image after the luminance range adjustment, and the second target image is superimposed on the first target image.

[0173] In an embodiment, the adjusting module 1020 is specifically configured to reduce the picture content luminance range of the first target image according to a first target adjustment parameter, and increase the backlight luminance range of the first target image and the second target image according to a second target adjustment parameter, the first target adjustment parameter and the second target adjustment parameter being two preset adjustment ratios that are reciprocal to each other.

[0174] In an embodiment, the adjusting module 1020 is specifically configured to determine a target adjustment range of the picture content luminance according to the first target adjustment parameter, the target adjustment range of the picture content luminance being smaller than a current range of the picture content luminance, and map the picture content luminance of the first target image from the current range to the target adjustment range.

[0175] In an embodiment, the adjusting module 1020 is specifically configured to determine a target adjustment range of the backlight luminance according to the second target adjustment parameter, the target adjustment range of the backlight luminance being greater than a current range of the backlight luminance, and map the backlight luminance of the first target image and the second target image from the current range to the target adjustment range.

[0176] In an embodiment, the adjusting module 1020 is specifically configured to reduce the picture content luminance range of all regions of the first target image according to the first target adjustment parameter, or reduce the picture content luminance range of a target region of the first target image according to the first target adjustment parameter, the target region being a region of the first target image except at least one element corresponding to the second target image.

[0177] In an embodiment, the adjusting module 1020 is specifically configured to increase the picture content luminance range of the first target image according to a third target adjustment parameter, and reduce the backlight luminance range of the first target image and the second target image according to a fourth target adjustment parameter, the third target adjustment parameter and the fourth target adjustment parameter being two preset adjustment ratios that are reciprocal to each other.

[0178] In an embodiment, the generating module 1010 is specifically configured to acquire image information of the first target image, determine at least one target element from the first target image based on the image information, and generate the second target image based on the at least one target element.

[0179] In one embodiment, the generation module 1010 is specifically used to perform image recognition processing on the first target image to obtain background elements and non-background elements in the first target image; and generate a second target image based on the background elements or non-background elements.

[0180] In the image display device provided in this application embodiment, a second target image can be generated after adjusting the brightness range of a first target image. The second target image includes at least one element of the first target image. The brightness range of the content of the first target image and the backlight brightness range of the first and second target images are adjusted, with the adjustment directions of the content brightness range and the backlight brightness range being opposite. The first and second target images after brightness range adjustment are displayed, wherein the second target image is superimposed on the first target image. By adjusting the content brightness range and backlight brightness range of the first target image and adjusting the display brightness range of the second target image, the dynamic range of the first and second target images can be adjusted, thereby creating a difference in the dynamic range of the first and second target images. This further improves the contrast between the first and second target images, thereby improving the display effect of the second target image. Furthermore, since the processing involves adjusting the brightness range, the computational content is small, and it does not cause problems such as lag in the terminal device. It can improve the contrast of different layers in the image while avoiding device lag.
