[0002] With the rapid development of display devices, users have put forward higher requirements for the displayed images of display devices. The more accurate the exposure adjustment parameters of the images are, the clearer the displayed brightness of the images will be.
[0003] Currently, when adjusting the exposure of the displayed image of a display device, generally, the exposure adjustment parameters are determined according to the panoramic brightness data in the panoramic image collected by a camera, and then the brightness of the target image included in the panoramic image is adjusted according to the determined exposure adjustment parameters, where the target image is a partial image of the panoramic image.
[0004] However, the existing technology is prone to cause underexposure or overexposure problems of the target image, resulting in the target image being displayed too dark or too bright. Summary of the Invention

[0006] In a first aspect, embodiments of the present application provide a display device, where the display device includes:
[0007] A camera configured to: collect image information and generate a panoramic image according to the image information;
[0008] A processor connected to the camera, the processor being configured to: obtain the panoramic image;
[0009] Determine a target image from the panoramic image, where the target image is a partial image of the panoramic image;
[0010] Obtain the position information of the target image in the panoramic image;

[0014] A display screen connected to the processor, the display screen being configured to: display the adjusted target image.
[0015] In this application, when the processor adjusts the exposure of the target image, it segments the target image from the panoramic image and obtains the brightness data of the target image, and adjusts the current exposure adjustment parameter data of the target image only according to the brightness data of the target image, improving the situation of underexposure or overexposure of the image caused by using the panoramic brightness data of the target image to adjust the current exposure adjustment parameter data, making the display brightness of the adjusted target image more in line with the user's picture quality experience requirements.
[0016] In some embodiments of this application, when the processor is configured to determine the target image from the panoramic image, it is specifically configured to:
[0017] Obtain the electronic zoom and focus data of the camera;
[0018] According to the electronic zoom and focus data, determine the target image from the panoramic image;
[0019] Or, obtain the shooting mode of the camera;
[0020] According to the shooting mode, determine the target image from the panoramic image.
[0021] In this application, the processor can determine the target image from the panoramic image according to the electronic zoom and focus data of the camera or the shooting mode of the camera. By providing multiple ways to determine the target image, the diversity of the method for determining the target image is improved.
[0022] In some embodiments of this application, when the processor is configured to obtain the position information of the target image in the panoramic image, it is specifically configured to:
[0023] Based on a marquee of a preset shape, wrap the target image in the marquee;
[0024] Obtain the vertex coordinate information of the marquee to obtain the position information of the target image in the panoramic image.
[0025] In this application, the processor wraps the target image in a marquee of a preset shape, and then determines the vertex coordinates of the marquee including the target image as the position information of the target image, reducing the problem of large computational complexity caused by obtaining its position information if the shape of the target image is too complex, and improving the efficiency and convenience of obtaining the position information of the target image.
[0026] In some embodiments of this application, the processor is further configured to:
[0027] Obtain the luminance data of the entire area in the panoramic image;
[0028] Divide the luminance data of the entire area into luminance data of a preset number of sub-areas, and obtain the position information corresponding to the sub-areas.
[0029] In this application, the processor divides the entire area in the panoramic image to obtain multiple sub-areas, and obtains the luminance data and position information of each sub-area, which is convenient for more accurately determining the luminance data of the target image subsequently.
[0030] In some embodiments of this application, when the processor is configured to obtain the current luminance data of the target image, it is specifically configured to:

[0035] In some embodiments of this application, when the processor is configured to adjust the exposure adjustment parameter data of the target image currently according to the magnitude relationship between the luminance data and a preset luminance data threshold until the adjusted luminance data reaches the preset luminance data threshold, it is specifically configured to:
[0036] If the luminance data does not exceed the preset luminance data threshold, increase the exposure adjustment parameter data of the target image currently until the adjusted luminance data reaches the preset luminance data threshold.
[0037] In this application, if the luminance data of the target image does not exceed the preset luminance data threshold, it indicates that the target image is currently underexposed. By increasing the exposure adjustment parameter data, the display luminance of the target image is improved, and the problem of too dark display of the target image is improved.
[0038] In some embodiments of the present application, when the processor is configured to adjust the current exposure adjustment parameter data of the target image according to the magnitude relationship between the brightness data and a preset brightness data threshold until the adjusted brightness data reaches the preset brightness data threshold, it is specifically configured as follows:
[0039] If the brightness data exceeds the preset brightness data threshold, then reduce the current exposure adjustment parameter data of the target image until the adjusted brightness data reaches the preset brightness data threshold.
[0040] In the present application, if the brightness data of the target image exceeds the preset brightness data threshold, it indicates that the target image is currently overexposed. By reducing the exposure adjustment parameter data, the display brightness of the target image is reduced, and the problem of the target image being too bright in display is improved.

[0050] In the present application, when adjusting the exposure of the target image, by segmenting the target image from the panoramic image and obtaining the brightness data of the target image, and adjusting its exposure adjustment parameter data only according to the brightness data of the target image, the problem of underexposure or overexposure of the image caused by adjusting the current exposure adjustment parameter data using the panoramic brightness data of the target image is improved, making the display brightness of the adjusted target image more in line with the user's image quality experience requirements.

[0068] To make the objectives, implementation manners, and advantages of the present application clearer, the following will clearly and completely describe the exemplary implementation manners of the present application with reference to the accompanying drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.
[0069] It should be noted that the brief description of the terms in the present application is only for facilitating the understanding of the subsequent described implementation manners, rather than intending to limit the implementation manners of the present application. Unless otherwise specified, these terms should be understood in their ordinary and general meanings.
[0070] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device including a series of components does not necessarily have to be limited to those clearly listed components, but may include other components not clearly listed or inherent to these products or devices.
[0071] With the rapid development of display technology, more and more display devices are beginning to be equipped with cameras to meet the usage requirements of different scenarios. Taking the conference large screen applied in the conference scenario as an example, after the camera of the conference large screen captures an image through operations such as zooming, focusing, or close-up tracking, it is necessary to perform exposure on the image to adjust the display brightness of the image.
[0072] In the prior art, when adjusting the exposure of a displayed image, usually, the exposure adjustment parameter is calculated according to the statistical value of the brightness data in the panoramic image captured by the camera, and the brightness of a partial image included in the panoramic image, that is, the target image, is adjusted according to the exposure adjustment parameter.
[0073] However, in the prior art, since the exposure adjustment parameter of the target image is determined based on the brightness data of the panoramic image rather than the brightness data of the target image itself, it is likely to result in inaccurate determination of the exposure adjustment parameter of the target image, leading to under-exposure or over-exposure of the target image, and further causing the display brightness of the target image to be too dark or too bright, thus affecting the user's viewing experience.
[0074] Therefore, in view of the above technical problems in the prior art, the present application proposes a display device, an image exposure adjustment method, a medium and a product for the display device. The display device includes a camera, a processor, and a display screen. The camera captures full-screen image information to obtain a panoramic image. The processor determines a target image from the panoramic image and performs segmentation after obtaining the position information of the target image to obtain the target image. The processor obtains the current brightness data and the current exposure adjustment parameter data of the target image, and adjusts the current exposure adjustment parameter data of the target image according to the magnitude relationship between the brightness data and a preset brightness data threshold until the adjusted brightness data reaches the preset brightness data threshold. Finally, the display screen displays the adjusted target image. In the present application, by adjusting the current exposure adjustment parameter data only based on the brightness data of the target image, the situation of under-exposure or over-exposure of the image caused by the prior art is improved, and the display effect of the image is enhanced.
[0075] To facilitate the understanding of the present application, an application scenario is provided below by way of example. Figure 1 The following is a schematic diagram of an application scenario provided by the present application, as Figure 1 shown:
[0076] Taking a conference large screen applied in a conference scenario as an example, the conference large screen 10 includes: a camera 101, a processor 102, and a display screen 103.
[0077] Among them, the camera 101 is used for: capturing image information to obtain a panoramic image;
[0078] The processor 102 is used for: determining a target image from the panoramic image and obtaining the brightness data of the target image, comparing the brightness data with a preset brightness data threshold. If they are the same, exposure adjustment is performed according to the current exposure adjustment parameter data. If they are different, the exposure adjustment parameter data is adjusted according to the magnitude relationship between the brightness data and the preset brightness data threshold until the adjusted brightness data is the same as the preset brightness data threshold.
[0079] The display screen 103 is used for: displaying the adjusted target image.
[0080] It can be understood that the above scenarios are only for illustrative purposes. The application scenarios of the display device can also be educational scenarios, etc. In this application, the conference large screen can also be other display devices. In the specific application of the solution, it can be determined according to actual needs, and this application does not make any limitations.
[0081] The following will specifically describe the technical solution of this application and how this technical solution solves the above technical problems with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.
[0082] Figure 2 A schematic structural diagram of a display device provided by an embodiment of this application is shown as Figure 2 shown. The display device includes: a camera 201, a processor 202, and a display screen 203.
[0083] Their connection relationship is:
[0084] The camera 201 is connected to the processor 202, and the processor 202 is connected to the display screen 203.
[0085] Their functions are:
[0086] The camera 201 is configured to: collect image information and generate a panoramic image according to the image information.
[0087] In this embodiment, the camera 201 can also be other image acquisition devices. For example, a camera, an image acquisition instrument, etc. The camera 201 can collect image information in a preset space at preset intervals or in real time, and generate a panoramic image according to the collected image information.
[0088] Exemplarily,
[0089] Figure 3A A schematic diagram of a panoramic image provided by an embodiment of this application is shown as Figure 3A shown. Assuming that the image information collected by the camera 201 is human information, the panoramic image generated according to the human information includes three persons, namely person 1, person 2, and person 3.
[0090] The processor 202 is configured to: obtain the panoramic image.
[0091] In this embodiment, an image processing chip is configured in the processor 202. Among them, the processor 202 can also be a controller, an SOC main control chip, or an operating system, etc. This application does not limit its type.
[0092] The processor 202 determines a target image from the panoramic image, where the target image can be a partial image of the panoramic image.
[0093] One possible implementation is as follows:
[0094] Obtain the electronic zoom and focus data of the camera 201, and determine the target image from the panoramic image according to the electronic zoom and focus data.
[0095] Exemplarily,
[0096] Assume that the obtained electronic zoom and focus data of the camera 201 is a 10-fold focal length. After the focal length is magnified by 10 times, Figure 3A Among the three people in the panoramic image, only one person may remain. Then the remaining person 2 is the target image, and a schematic diagram of the target image as shown in Figure 3B is obtained.
[0097] Another possible implementation is as follows:
[0098] Obtain the shooting mode of the camera 201, and determine the target image from the panoramic image according to the shooting mode.
[0099] Exemplarily,
[0100] Assume that the obtained shooting mode of the camera 201 is the animal capture mode. If the panoramic photo includes both animal images and non-animal images, according to this shooting mode, the animal image can be determined as the target image.
[0101] It can be understood that there may also be other ways to determine the target image in this application. For example, in response to a selection operation of the user in the panoramic image, the object selected by the user in the panoramic image can be determined as the target image. Another example is to determine the person currently speaking as the target image according to the people in the panoramic image in cooperation with other sound collection devices, etc. This application does not limit the way to determine the target image.
[0102] The processor 202 is further configured to: obtain the position information of the target image in the panoramic image, and segment the panoramic image according to the position information to obtain the target image.
[0103] In this embodiment, when the processor 202 obtains the position information of the target image in the panoramic image, it is based on a selection box of a preset shape, wraps the target image in the selection box, and then obtains the vertex coordinate information of the selection box to obtain the position information of the target image in the panoramic image.
[0104] Exemplarily,
[0105] Figure 4This is a schematic diagram of the position information of a target image provided by an embodiment of the present application. As shown in FIG. 4, a marquee of a preset shape takes a rectangular box as an example, and the rectangular box completely encloses the target image. By obtaining the coordinate information of the four vertices of the rectangular box, the coordinate information of the four vertices is determined as the position information of the target image in the panoramic image.
[0106] It can be understood that the above-mentioned marquee shape is only for illustrative purposes, and the present application does not limit the marquee shape, which can be determined according to the actual situation.
[0107] After obtaining the position information of the target image, further based on the position information of the target image and a preset segmentation algorithm, the panoramic image is segmented, and finally the target image as shown in Figure 3B is obtained.
[0108] The processor 202 is further configured to: obtain the current brightness data and the current exposure adjustment parameter data of the target image, and adjust the current exposure adjustment parameter data of the target image according to the magnitude relationship between the brightness data and a preset brightness data threshold until the adjusted brightness data reaches the preset brightness data threshold.
[0109] In this embodiment, the processor 202 only obtains the current brightness data of the target image, and then compares the current brightness data of the target image with a preset brightness data threshold, and adjusts the exposure parameters according to the comparison result.
[0110] The specific implementation process will be described in detail in the following embodiments. Please refer to the following embodiments.
[0111] The display screen 203 is configured to: display the adjusted target image.
[0112] After the processor 202 completes the exposure adjustment of the target image, the display screen 203 displays the adjusted target image. At this time, the brightness of the target image is neither too dark nor too bright.
[0113] In the above embodiments of the present application, the display device includes a camera 201, a processor 202, and a display screen 203. The camera 201 captures full-screen image information to obtain a panoramic image. After the processor 202 determines a target image from the panoramic image and obtains the position information of the target image, it performs segmentation to obtain the target image. The processor 202 can also obtain the current brightness data of the target image and the current exposure adjustment parameter data. According to the magnitude relationship between the brightness data and the preset brightness data threshold, it adjusts the current exposure adjustment parameter data of the target image until the adjusted brightness data reaches the preset brightness data threshold. Finally, the display screen 203 displays the adjusted target image. When the display device of the present application adjusts the exposure of the target image, by segmenting the target image in the panoramic image and obtaining the brightness data of the target image, and only adjusting the current exposure adjustment parameter data according to the brightness data of the target image, it improves the situation of underexposure or overexposure of the image caused by using the panoramic brightness data of the target image to adjust the current exposure adjustment parameter data, making the display brightness of the adjusted target image more in line with the user's picture quality experience requirements and improving the user experience.
[0114] Further, on the basis of the above embodiments, through the following embodiments, the process of the processor obtaining the current brightness data of the target image is described.
[0115] Figure 5 It is a schematic flowchart of a method for obtaining the current brightness data of a target image provided by an embodiment of the present application. As Figure 5 shown, the processor is configured to perform the following steps:
[0116] S501. Compare the position information of the target image in the panoramic image with the position information corresponding to the sub-region to determine the target sub-region occupied by the target image.
[0117] In the present application, before the processor makes the comparison, it first obtains the brightness data of the entire region in the panoramic image, divides the brightness data of the entire region into the brightness data of a preset number of sub-regions, and at the same time obtains the position information corresponding to each sub-region.
[0118] As Figure 6 shown, Figure 6 It is a schematic diagram of a sub-region provided by an embodiment of the present application. In Figure 6 , the entire region 601 is divided into M×N sub-regions 602, and each sub-region 602 corresponds to its own brightness data and its own position information.
[0119] Assume that the shape of the sub-region is rectangular, then the position information of each sub-region is the coordinate information of the four vertices. If the selection box containing the target image is rectangular, compare the coordinate information of the four vertices of the target image in the panoramic image with the coordinate information of the four vertices of each sub-region, and the target sub-region occupied by the target image can be obtained.
[0120] Exemplarily,
[0121] Figure 7A is a schematic diagram of a target sub-region provided by an embodiment of the present application. In Figure 7A if the figure enclosed by the coordinate information of the four vertices of the target image in the panoramic image completely occupies at least one complete sub-region, then this sub-region is Figure 7A The shaded area marked in is the target sub-region occupied by the target image.
[0122] Figure 7B is another schematic diagram of a target sub-region provided by an embodiment of the present application. In Figure 7B if there are both complete sub-regions completely occupied and sub-regions not completely occupied in the figure enclosed by the coordinate information of the four vertices of the target image in the panoramic image, then the completely occupied sub-regions are Figure 7B The shaded area marked in is the target sub-region occupied by the target image.
[0123] S502. Obtain the brightness data corresponding to the target sub-region.
[0124] S503. Obtain the current brightness data of the target image according to the brightness data corresponding to the target sub-region.
[0125] After the processor determines the target sub-region, obtain the brightness data of each target sub-region. As Figure 7A shown, assume there are ten target sub-regions, then obtain the brightness data of these ten target sub-regions, and perform a summation process on the ten brightness data to obtain the current brightness data of the target image.
[0126] Furthermore, after obtaining the current brightness data of the target image, compare the current brightness data with a preset brightness data threshold.
[0127] If the brightness data does not exceed the preset brightness data threshold, it indicates that the target image is currently underexposed, then increase the current exposure adjustment parameter data of the target image until the adjusted brightness data reaches the preset brightness data threshold to prevent the target image from being displayed too dark.
[0128] If the brightness data exceeds the preset brightness data threshold, it indicates that the target image is currently overexposed, then decrease the current exposure adjustment parameter data of the target image until the adjusted brightness data reaches the preset brightness data threshold to prevent the target image from being displayed too bright.
[0129] In the actual application process, the preset brightness data threshold can be an interval value rather than a fixed value to reduce the difficulty of exposure adjustment.
[0130] In the above embodiments of the present application, the processor compares the position information of the target image in the panoramic image with the position information corresponding to the sub-region to determine the target sub-region occupied by the target image, and obtains the brightness data corresponding to the target sub-region. Furthermore, based on the brightness data corresponding to the target sub-region, the current brightness data of the target image obtained is more accurate.
[0131] In the present application, if the electronic zoom and focus data of the camera changes, the camera mode changes, the camera angle changes, etc., the target image can also be re-determined from the panoramic image according to the change, such as Figure 8 shown. Figure 8 FIG. is another schematic diagram of the target image provided by the embodiment of the present application, taking Figure 3A the three people in it as an example. Suppose the previously determined target image is person 2, and the re-determined target image is person 1. Then, the exposure adjustment of the determined target image is re-performed according to the method described above in the present application. Since the stable residence time of the target screen is much longer than the exposure adjustment time, even if the next target image changes, the exposure adjustment of the previous target image has been completed, so that the change of the current target image can be quickly adapted to.
[0132] Figure 9 FIG. is a schematic flowchart of an image exposure adjustment method for a display device provided by an embodiment of the present application, such as Figure 9 shown. The method includes the following steps:
[0133] S901. The camera collects image information and generates a panoramic image according to the image information.
[0134] S902. The processor obtains the panoramic image.
[0135] S903. The processor determines a target image from the panoramic image, and the target image is a partial image of the panoramic image.
[0136] S904. The processor obtains the position information of the target image in the panoramic image.
[0137] S905. The processor segments the panoramic image according to the position information to obtain the target image.
[0138] S906. The processor obtains the current brightness data and the current exposure adjustment parameter data of the target image.
[0139] S907. The processor adjusts the current exposure adjustment parameter data of the target image according to the magnitude relationship between the brightness data and the preset brightness data threshold until the adjusted brightness data reaches the preset brightness data threshold.
[0140] S908. The display screen displays the adjusted target image.
