[0043] The beneficial effects of the embodiments in this application compared with the prior art are:

[0044] The display area adjustment method of this application is applied to an electronic device, which includes a curved screen. The method involves acquiring a target image and target movement information of a target object, including gestures or facial expressions.

[0059] Currently, curved flexible screens are installed on the side walls of smart speakers to allow users to watch videos. However, due to the varying viewing angles of these curved screens, viewers cannot see the entire screen, impacting the viewing experience. Existing technology uses a display area that follows the viewer's face to adjust its position. However, due to physiological needs and daily activities, faces cannot remain in a fixed position and need to move frequently. This causes the display area to move continuously with the face, resulting in screen flickering and eye strain, further reducing the user experience.

[0060] Therefore, existing technologies suffer from the problem that the display area of ​​curved screens frequently moves, causing the image to shake, which reduces the user's viewing experience and overall experience.

[0061] This application provides a method for adjusting a display area, applied to an electronic device including a curved screen. The method involves acquiring a target image and target movement information of a target object, including gestures or facial expressions. If the target image and a preset image of the target object meet preset matching conditions, region adjustment information for the display area is determined based on the target movement information. This region adjustment information represents information about the display area of ​​a preset curved surface size following the movement of the target object. Based on the target movement information and the region adjustment information, a shaking parameter for the display area is determined. Shaking display compensation is then performed on the display area based on the target movement information and the shaking parameter. Because the shaking parameter is determined and the display area is compensated for after determining the region adjustment information, the impact of display area shaking on the user's viewing experience is reduced, excessive following of movement by the display area is avoided, eye fatigue is reduced, and the user's viewing experience is improved.

[0062] The technical solution of this application will be described below through specific embodiments.

[0063] Firstly, such as Figure 1 As shown, this embodiment provides a method for adjusting the display area, applied to an electronic device, which includes a curved screen. The adjustment method includes:

[0064] S100, acquire the target image and target movement information of the target object respectively, the target object includes gestures or facial expressions.

[0065] In one embodiment, Figure 2 This is a schematic diagram of the overall structure of an electronic device equipped with a curved screen. The electronic device acquires a target image and target movement information of a target object through an image sensing sensor (e.g., a camera), thereby identifying the target object and sensing its movement information. This facilitates subsequent data processing and allows for adjustment of the position and / or range of the display area. In one embodiment, the target object includes a gesture or facial expression, the target image is an image of the gesture or facial expression, and the target movement information is the movement information of the gesture or facial expression.

[0066] In one embodiment, the gestures or facial expressions are preset gestures or preset facial expressions to avoid unintentional routine gestures or everyday facial expressions triggering the display area adjustment function.

[0067] It should be noted that the target object is not limited to gestures or facial expressions; the target object can also be a target object, which includes various items or any combination of items, such as mobile phones, teacups, stationery, toys, etc.

[0068] S200, if the target image and the preset image of the target object meet the preset matching conditions, based on the target movement information, determine the area adjustment information of the display area. The area adjustment information represents the adjustment information of the display area of ​​the preset curved surface size as the target object moves.

[0069] In one embodiment, if the target image and the preset image of the target object meet the preset matching conditions, the area adjustment information of the display area is determined based on the target movement information. This is beneficial for the electronic device to start the movement of the display area based on the matching of the target image and the corresponding preset image. Compared with the prior art, this avoids the display area from constantly moving with the movement of the face, causing the display area to move frequently, which causes the human eye to constantly focus on the display area, increases the degree of eye fatigue, and reduces the user experience.

[0070] In one embodiment, the area adjustment information includes the area movement path and the area movement speed, which facilitates better adjustment of the display area.

[0071] In one embodiment, such as Figure 3 As shown, if the target image and the preset image of the target object meet the preset matching conditions, based on the target movement information, the area adjustment information of the display area is determined, including:

[0072] S210, based on the target image and the preset image of the target object, determine whether the target image and the preset image meet the preset matching conditions.

[0073] In one embodiment, the target image is matched and compared with a corresponding preset image pre-stored in the electronic device to determine the timing of the display area adjustment, thereby avoiding random triggering of the display area adjustment function by everyday gestures, faces, facial expressions, or target objects.

[0074] S220, if the target image and the preset image meet the preset matching conditions, determine the area movement path of the display area based on the target movement information.

[0075] In one embodiment, if the target image and the preset image meet the preset matching conditions, the display area adjustment function is enabled. Based on the target movement information, the region movement path of the display area is determined, which is beneficial for adjusting the display area according to the region movement path.

[0076] In one embodiment, the target image includes a first target image and a second target image, which respectively represent images of the target object at different times. The preset image includes a first preset image corresponding to the first target image and a second preset image corresponding to the second target image. The target image and the preset image have a corresponding relationship, which facilitates rapid identification by electronic devices, improves response speed, and avoids accidental triggering and adjustment of the display area.

[0077] In one embodiment, the movement path includes a starting movement position and an ending movement position. The position of the display area corresponding to the recognition of the first target image is set as the starting movement position, and the position of the display area corresponding to the recognition of the second target image is set as the ending movement position. This helps to clarify the adjustment range and adjustment time of the display area.

[0078] In one embodiment, the preset matching conditions include a first preset matching condition and a second preset matching condition. The first preset matching condition is used to determine whether the matching degree between the first target image and the first preset image meets the matching requirements, and the second preset matching condition is used to determine whether the matching degree between the second target image and the second preset image meets the matching requirements.

[0079] In one embodiment, such as Figure 4 As shown, if the target image and the preset image meet the preset matching conditions, the region movement path of the display area is determined based on the target movement information, including:

[0080] S221, if the first target image and the first preset image meet the first preset matching conditions, determine the starting movement position of the display area based on the target movement information.

[0081] In one embodiment, if the first target image and the first preset image meet the first preset matching condition, the display area adjustment function is triggered, and the starting movement position of the display area when the adjustment function is triggered is determined based on the target movement information.

[0082] In one embodiment, the first target image is a pouting expression. If the pouting expression meets the first preset matching condition with a preset pouting expression, the adjustment function of the display area is triggered. Based on the movement information of the face maintaining the pouting expression, the starting movement position of the display area when the adjustment function is triggered is determined.

[0083] S222, if the second target image and the second preset image meet the second preset matching conditions, determine the end movement position of the display area based on the target movement information.

[0084] In one embodiment, if the second target image and the second preset image meet the second preset matching condition, the adjustment function of the display area is stopped. Based on the target movement information, the end movement position of the display area when the adjustment function is stopped is determined, which is helpful in determining the movement path of the display area.

[0085] In one embodiment, the second target image is a normal facial expression without pouting. If the normal facial expression without pouting meets the second preset matching condition with the preset face image, the adjustment function of the display area is stopped. Based on the stop movement information of the normal facial expression without pouting, the end movement position of the display area when the adjustment function is stopped is determined.

[0086] S223, determine the area movement path of the display area based on the starting movement position and the ending movement position.

[0087] In one embodiment, based on the starting and ending moving positions, the movement trajectory of the display area during the process from the starting and ending moving positions is saved, thereby determining the area movement path of the display area, which is beneficial for adjusting the display area according to the area movement path.

[0088] In one embodiment, the image content of the first target image and the second target image are the same, or the image content of the first target image and the second target image are different. When the image content of the first target image and the second target image are the same, the amount of computation is reduced, which makes it easier for the electronic device to quickly identify and improve the response speed. When the image content of the first target image and the second target image are different, the electronic device can distinguish between the two target images, avoid misidentification and stop adjusting the display area before the display area has reached the specified position, and improve the accuracy of the electronic device in adjusting the display area.

[0089] In one embodiment, to reduce the likelihood of the display area adjustment function being accidentally triggered, the matching percentage of the first preset matching condition is set to be greater than or equal to the matching percentage of the second preset matching condition. It should be noted that the specific range of the matching percentage setting is determined according to the needs of the specific scenario; for example, the matching percentage of the first preset matching condition may be greater than or equal to 90%, or greater than or equal to 85%.

[0090] In one embodiment, the area adjustment information also includes the display area range, which facilitates adaptive adjustment of the size of the display area.

[0091] In one embodiment, if the target image and the preset image of the target object meet preset matching conditions, the region adjustment information of the display area is determined based on the target movement information. The method further includes: if the target image and the preset image of the target object meet preset matching conditions, the display area range of the display area is determined based on the target movement information.

[0092] In one embodiment, the preset matching conditions further include a third preset matching condition and a fourth preset matching condition.

[0093] In one embodiment, if the target image and a preset image of the target object satisfy preset matching conditions, the display area range of the display area is determined based on the target movement information, including:

[0094] Based on the target image and a preset image of the target object, it is determined whether the target image and the preset image meet preset matching conditions. If the first target image and the first preset image meet a third preset matching condition, the starting display area range of the display area is determined based on the target movement information. If the second target image and the second preset image meet a fourth preset matching condition, the ending display area range of the display area is determined based on the target movement information. That is, when the first target image and the first preset image meet the third preset matching condition, the display area range adjustment function of the display area is triggered to determine the starting display area range of the display area. When the second target image and the second preset image meet the fourth preset matching condition, the display area range adjustment function of the display area is stopped to determine the ending display area range of the display area, which facilitates adjustment of the display area range according to the user's habitual and preferred position.

[0095] In one embodiment, when the first target image and the first preset image meet a third preset matching condition, a dashed border is displayed at the boundary of the display area. During the movement of the target object, the dashed border is scaled up or down according to a preset definition. When the second target image and the second preset image meet a fourth preset matching condition, the display area is adjusted to the range enclosed by the dashed border, and the dashed border is hidden at the boundary of the display area. The dashed border is set to semi-transparent, with both the inside and outside of the border being transparent, so as not to affect the user's viewing of the video.

[0096] It should be noted that the starting and ending display areas of the display area can be adjusted based on the target movement information. The direction of the target movement information can be customized to expand or shrink the display area, and the speed of the target movement information can also be customized to expand or shrink the display area. In this embodiment, no specific restrictions are imposed, and specific settings can be made according to the user's needs.

[0097] In one embodiment, the third preset matching condition may be the same as or different from the first preset matching condition, and the fourth preset matching condition may be the same as or different from the second preset matching condition. The specific matching percentage is set according to the user's needs.

[0098] S230, determine the area movement speed of the display area based on the area movement path.

[0099] In one embodiment, in order to accommodate the sensitivity requirements of different users for adjusting the display area, the area movement speed includes a first area movement speed and a second area movement speed.

[0100] In one embodiment, such as Figure 5 As shown, the area movement speed of the display area is determined based on the area movement path, including:

[0101] S231, based on the area movement path and the first duration of the area movement path, determine the first area movement speed of the display area.

[0102] S232, based on the area movement path and the second duration of the area movement path, determine the second area movement speed of the display area, wherein the second duration is greater than or equal to the first duration, and the second area movement speed is less than or equal to the first area movement speed.

[0103] It should be noted that when the second duration is longer than the first duration, the movement speed of the second area is slower than that of the first area because the movement path is the same. Therefore, users who prefer high sensitivity can speed up the movement speed of the first and second target images when the movement path is the same, thus speeding up the adjustment of the display area. Conversely, users who prefer low sensitivity will slow down the movement speed of the first and second target images when the movement path is the same, gradually adjusting the display area to a more suitable viewing area.

[0104] S300 determines the shaking parameters of the display area based on target movement information and area adjustment information.

[0105] In one embodiment, the shaking parameters include the regional position difference and the center change frequency. The regional position difference represents the position difference of the display area before and after following the target object's movement, and the center change frequency represents the number of times the center position of the display area changes during the movement of the target object. Based on the target movement information and the regional adjustment information, the shaking parameters of the display area are determined, which is beneficial for compensating the display area according to the shaking parameters to improve the user's viewing experience.

[0106] It should be noted that the area position difference can be the position difference between the four boundary vertices of the display area before and after moving with the target object, or the position difference between the center point of the display area before and after moving with the target object, or the position difference between a specified reference point of the display area before and after moving with the target object. The specific setting depends on the needs.

[0107] In one embodiment, such as Figure 6 As shown, based on target movement information and area adjustment information, the shaking parameters of the display area are determined, including:

[0108] S310, based on target movement information and area adjustment information, determines the regional position difference of the display area.

[0109] S320 determines the frequency of center change of the display area based on target movement information and area adjustment information.

[0110] In one embodiment, the regional position difference and center change frequency of the display area are determined based on the target movement trajectory and the regional movement path, regional movement speed, or display area range. This is beneficial for compensating for shaking display based on the regional position difference and center change frequency.

[0111] S400 performs shake display compensation on the display area based on target movement information and shake parameters.

[0112] In one embodiment, the display area is compensated for shaking based on target movement information and shaking parameters. Because the display area is compensated for shaking, the impact of the shaking of the display area on the user's viewing experience is reduced, excessive following of the display area is avoided, eye fatigue is reduced, and the user's viewing experience is improved.

[0113] In one embodiment, such as Figure 7 As shown, the display area is compensated for shaking based on target movement information and shaking parameters, including:

[0114] S410 determines position difference display compensation based on target movement information and regional position difference.

[0115] In one embodiment, the target movement information includes the target movement trajectory. Based on the target movement trajectory of the target object and the regional position difference, the average value of the regional position difference is calculated by dividing by 2. Half of the regional position difference is determined as the display area position difference display compensation. That is, the display area is set at the midpoint between the position of the display area before it moves with the target object and the position of the display area after it moves with the target object. The compensated display area is located in the target movement trajectory, which avoids the user's viewing area changing too much and improves the user's viewing experience.

[0116] In another embodiment, the target movement information includes the target movement trajectory. Based on the target movement trajectory and the regional position difference, the regional position difference is continuously calculated during the target movement trajectory. Then, a weighted average of the regional position difference is calculated, and the weighted average of the regional position difference is determined as the position difference display compensation for the display area. This smooths the process of the display area's position before and after following the target object's movement, and the compensated display area is located within the target movement trajectory. This avoids excessive changes in the display area viewed by the user, reduces the number of times the user's eyes need to focus, reduces eye fatigue, and improves the user's viewing experience.

[0117] In one embodiment, the target movement trajectory is a movement trajectory of the target object formed based on the geometric center of the target object.

[0118] S420 determines center display compensation based on target movement information and center change frequency.

[0119] In one embodiment, based on the target movement information and the center change frequency, the median value of the center change frequency is used for center display compensation. This reduces the number of times the display area changes its center position due to the target object's movement, thereby reducing the frequency of the display area changing its center position due to the target object's movement, reducing the number of times the user's eyes have to focus, reducing the user's eye fatigue, and improving the user's viewing experience.

[0120] In one embodiment, based on the target movement information of the target object, the target object moves from position A to position B. The center position of the display area changes 5 times. Then, the midpoint of 5 times (3 times) is taken as the center display compensation. That is, the center position of the display area actually only changes 3 times from the position corresponding to position A to the position corresponding to position B. This reduces the frequency of the center position change caused by the display area moving with the target object, reduces the number of times the user's eyes have to focus, reduces the user's eye fatigue, and improves the user's viewing experience.

[0121] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0122] The beneficial effects of the embodiments in this application compared with the prior art are:

[0123] The display area adjustment method of this application is applied to an electronic device, which includes a curved screen. The method involves acquiring a target image and target movement information of a target object, including gestures or facial expressions. If the target image and a preset image of the target object meet preset matching conditions, region adjustment information of the display area is determined based on the target movement information. This region adjustment information represents the information that the display area of ​​a preset curved surface size follows the movement of the target object.
