It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The following describes embodiments of the present application in detail.

Referring to fig. 1, a flowchart illustrating steps of a display control method according to an embodiment of the present application is shown. The display control method is operated on an electronic device. Fig. 2 is a schematic view of an electronic device according to an embodiment of the present application. The electronic device 50 has a cylindrical body 580, a display 582, and an image sensor 584. Wherein the display 582 surrounds the body 580 and provides all or a portion of the body 580. The image sensor 584 is disposed on the body 580. In this embodiment, the display 582 may be a flexible display that may be fitted around the body 580. In other embodiments, the electronic device 50 may include a plurality of display screens, each of which is disposed at a corresponding position of the body 580. The display control method includes the steps of:

and step 100, controlling the image sensor to acquire an image in a preset area range relative to the body.

In this embodiment, the electronic device 50 may be a smart speaker. The cross-section of the body 580 is a circle with a radius r, and the radius r is the distance from the center o to the outer side wall of the body 580. In this embodiment, the display 582 may be disposed along the circumference of the body 580, and the display 582 is disposed on the entire circumference of the body 580, i.e., the length of the display 582 is equal to the circumference 2 π r of the body 580. In other embodiments, the display 582 is disposed on a portion of the circumference of the body 580, i.e., the length of the display 582 is less than the circumference 2 π r of the body 580.

The body 580 is provided with a plurality of image sensors 584, and each image sensor 584 is configured to acquire an image within a preset area relative to the body 580.

The image sensor 584 may be a camera. The image sensor 584 may have a certain photographing viewing angle. In the present embodiment, the photographing angle of view is a horizontal photographing angle of view. In the present embodiment, the photographing angle of view of the image sensor 584 may be 120 °, and the image sensor 584 may be a fisheye camera. Since the peripheral scene of the body 580 has 360 °, in order to photograph all the peripheral scenes of the body 580, the peripheral scene of the body 580 may be divided or set into a plurality of preset area ranges, for example, 3 preset area ranges, where each preset area range is 120 degrees, and each preset area range corresponds to an area between two view angle edge lines.

Fig. 3 is a schematic diagram illustrating a position of an image sensor according to an embodiment of the present application. The peripheral scene of the body 580 includes a first preset area range, a second preset range and a third preset range. In this embodiment, the angle range value of each predetermined area range is set in a counterclockwise direction with one of the viewing angle borderlines oA being a starting edge of 0 °. For example, the first predetermined area range includes the area between the view angle edge oA and the view angle edge oB, and the corresponding angle range value [0 °, 120 °), the second predetermined area range includes the area between the view angle edge oB and the view angle edge oC, and the corresponding angle range value [120 °, 240 °), and the third predetermined area range includes the area between the view angle edge oC and the view angle edge oA, and the corresponding angle range value [240 °, 360 °). The view angle sideline oA intersects the display 582 attached to the outer sidewall of the body 580 at a point H, the view angle sideline oB intersects the display 582 attached to the outer sidewall of the body 580 at a point E, and the view angle sideline oC intersects the display 582 attached to the outer sidewall of the body 580 at a point F. In this embodiment, one image sensor 584 is disposed in each preset area, that is, three image sensors 584 may be disposed in the electronic device 50 to obtain images of all scenes around the periphery of the body 580. In other embodiments, the angular range value for each preset area range may be determined by other equations. For example, the viewing angle edge oA is set to 20 ° and the angle range value of each predetermined range is determined in the counterclockwise direction, at this time, the first predetermined range includes the range between the viewing angle edge oA and the viewing angle edge oB, and the corresponding angle range value [20 °, 140 °), the second predetermined range includes the range between the viewing angle edge oB and the viewing angle edge oC, and the corresponding angle range value [140 °, 260 °), and the third predetermined range includes the range between the viewing angle edge oC and the viewing angle edge oA, and the corresponding angle range value [260 °, 20 °). In other embodiments, the peripheral scene of the body 580 may also have 4 predetermined area ranges, that is, each predetermined area range is 90 °, in this case, the image sensor 584 may be a wide-angle camera, and thus, the image sensor 584 may determine the type of the camera according to the size of the angle range value of each predetermined area range.

In one embodiment, three image sensors 584 may be disposed at the center o. In another embodiment, the three image sensors 584 can be disposed above the center o through a specific structure, such as a straight line passing through the center o and aligned with the height direction X of the body 580, or disposed at a position above the circle where the center o is located and the distances from each image sensor to the center o are equal, or disposed on a concentric circle concentric with the center o and having a radius less than or equal to r.

In this embodiment, one image sensor is disposed in each preset area range, and the shooting direction of the image sensor is consistent with the center line position of the preset area range in which the image sensor is located. Since each preset area range is 120 degrees, and the shooting angle of view of each image sensor is 120 degrees, the shooting angle of view of each image sensor can be overlapped with the corresponding preset area range. For example, the three image sensors 584 may include a first image sensor, a second image sensor, and a third image sensor. The first image sensor can be arranged at the center of a circle and can acquire AoB images in a first preset area range, the middle position of the first preset area range is 60 degrees, and the shooting direction of the first camera is also 60 degrees; the second image sensor can be arranged at the circle center and can acquire an image of the BoC in a second preset area range, the middle position of the second preset area range is 180 degrees, and the shooting direction of the second camera is also 180 degrees; the third image sensor can be arranged at the center of the circle and can acquire an image of CoA in a third preset area range, the middle position of the third preset area range is 300 degrees, and the shooting direction of the third camera is also 300 degrees.

In one embodiment, the image sensor 584 may be disposed along a circumference of the body 580, such as disposing an image sensor 584 within each predetermined area. For example, the image sensor 584 is disposed at an intersection D of the center line oR within the first preset region range AoB and the display screen 582. Since the radius r of the body 580 is not much influenced by the calculation result relative to the distance DR that the image sensor can photograph or the distance between the user and the electronic device, or the image sensor disposed at the point D and the image sensor disposed at the center o can achieve substantially the same effect, that is, the image sensor disposed at the point D and the image sensor disposed at the center o can obtain the image within the first predetermined area, which is considered to be equivalent, and the influence on the subsequent calculation result can be ignored, the image sensor can also be disposed above the body 580.

Fig. 4 is a schematic view of a shooting angle of an image sensor according to an embodiment of the present disclosure. When the image sensor 584 is disposed on the outer sidewall of the body 580, if the shooting angle of the image sensor is the same as the preset area range where the image sensor is located, a certain blind area may exist during shooting. Therefore, when the image sensor 584 is disposed on the outer sidewall of the body 580, the shooting angle of the image sensor 584 can be adjusted to be larger than the predetermined area range. For example, the photographing angle of view of the image sensor is set to 160 °, and the first predetermined area range may be 120 °, wherein the first predetermined area range is located between the angle of view sideline oA and the angle of view sideline oB, and the photographing angle of view of the image sensor 584 may be represented as an angle corresponding to an area between the sideline DU and the sideline DV.

Step 102, judging whether the image contains human body features; if yes, go to step 104, otherwise, go back to step 100.

Fig. 5 is a schematic view of an image captured by an image sensor according to an embodiment of the present disclosure. In this embodiment, an image captured by an image sensor located in a first preset area is shown, and the image includes a human body feature S'. By detecting the human body characteristics of the image, when the human body characteristics are identified in the image, the image is judged to contain the human body characteristics; when the human body features are not identified in the image, the image is judged not to contain the human body features. In this embodiment, the human body feature may include a human face, that is, it may also be determined whether the image includes a human face feature to determine to execute step 104 or return to step 100.

And 104, acquiring position information of the user corresponding to the human body characteristics within the preset area range.

In this embodiment, the position information may be an area position angle of the user within the preset area range, where the area position angle is an included angle between a point (a user viewing position) where the user is located and a viewing angle sideline in the preset area range.

Referring to fig. 3, it is assumed that the user is located at a point S in the first predetermined area range AoB, and the image obtained by the first image sensor includes the human body feature S'. In this embodiment, the included angle between the point S and the viewing angle sideline oB can be expressed as an area position angle γ, which is ≈ BoS, and γ ∈ [0, 120 °), where the point S where the user is located is on a straight line AB perpendicular to the lens centerline OR. Δ AoB formed by viewing angle sidelines oA and oB is an isosceles triangle with an apex angle of 120 °, wherein ═ RoB is 60 °, Ao ═ Bo, and the area formula according to the isosceles triangle is:

simplified by equation (1):

therefore, the area position angle γ can be calculated from the ratio between the line segments AS and SB.

Referring to fig. 4, the human body feature S ' in the image corresponds to the user at the point S, and since the shooting angle of view of the image sensor coincides with the predetermined area range, the angle of view sideline oA may correspond to the first side a ' and the angle of view sideline oB may correspond to the second side B ' of the image width, so that:

as can be seen from the formulas (2) and (3), the region position angle γ can be calculated according to the division ratio of the human body feature S ' on the image width a ' B ' in the image.

In one embodiment, the region position angle may be an included angle between the point S and the viewing angle edge oA, such as represented by ≈ AoS, where:

formula of angle AoS (angle AoB-angle BoS) (4)

Therefore, when the value of the region position angle γ is calculated, another expression of the region position angle may also be calculated according to the formula (4). Since the viewing position of the user relative to the ontology is determined, both of the above two representations of the position information can obtain the same viewing position of the user at the corresponding ontology.

In an embodiment, a first distance a 'S' from the first side of the human body feature to the first side of the image may be obtained, and a second distance S 'B' from the second side of the human body feature to the second side of the image may be obtained, and then the position information γ may be calculated according to a ratio of the first distance a 'S' to the second distance S 'B'.

In one embodiment, the position of the center point of the human body feature (e.g., the position where the two dashed lines perpendicularly intersect in fig. 4) can be obtained. The central point position of the human body feature is represented as the central point of the geometric position corresponding to the human body feature in the image. Thus, the distance between the center point and the first side can be used as the first distance, and the distance between the center point and the second side can be used as the second distance.

In the present embodiment, when the image sensor 584 is disposed on the center of a circle, the image sensor 584 may obtain images corresponding to all scenes within a preset area range. When the image sensor 584 may be disposed in a circumferential direction of the body 580, the image sensor may obtain an image corresponding to a portion of the scene within a preset area. Because the lens center line of the image sensor is superposed with the center line position of the preset area range, when the image of a part of the scene in the preset area range is obtained, the position information of the user in the preset area range can be calculated according to the formula.

Referring to fig. 4, in an embodiment, the image sensor may be a depth camera, and when the image sensor is disposed at a point D on an outer sidewall of the body 580, the image sensor may obtain a distance SD between the points S and D. In addition, a depth camera can be arranged at the center o of the body 580, and can be used for obtaining the distance So between the point S where the user is located and the center o, and since the distance between the point D and the center o is the radius r, for the triangle SoD, the side SD, the side So, and the side Do of the triangle SoD can be determined, and then the ═ SoD can be calculated according to the cosine theorem of the triangle. Since the image sensor is located at the center line position of the first preset region range, the angle BoD is 60 °, that is, the region position angle γ ═ BoD ═ SoD, and thus, when the shooting angle of the image sensor is greater than the preset region range, the value of the region position angle can also be acquired. In other embodiments, the area position angle may also be obtained by other methods, which is not limited in this application.

And 106, determining the visual range of the user relative to the display screen according to the position information, and controlling the display screen to display the picture on the area of the display screen corresponding to the visual range.

For the display screen attached to the cylindrical body, the horizontal viewing angle alpha of the two eyes of the user is 188 degrees at most, and the horizontal viewing angle alpha of the two eyes of the user coincident is 124 degrees. In this embodiment, assuming that the horizontal viewing angle α of the user is 180 °, the center position of the display on the display screen 582 in the region corresponding to the visual range may be aligned with the user, where the visual range may be represented as:

(γ+α/2，γ-α/2)。

for example, when α is 180 °, the visual range can be expressed as: (gamma +90 DEG, gamma-90 DEG). In this way, the electronic device may control to display a corresponding picture on an area of the display screen corresponding to the visual range.

In one embodiment, since the radius of the body 580 is r and the circumference l of the body 580 is l ═ 2 π r, displaying a frame on the area of the display screen corresponding to the visual range may mean displaying a frame with a preset length on the display screen, where the preset length range is (T, I). The frame with the preset length can be determined by the visual range, where T represents a starting value of the preset length, I represents an ending value of the preset length, and the preset length can be expressed as:

in an embodiment, after the area position angle value is determined, the viewing position angle of the peripheral scene of the user on the body 580 may be determined according to the angle range value of the preset area range where the image sensor is located. For example, when the user views at the point S with the radius r as the starting edge of the viewing angle edge oA being 0 ° and sets the angle range value of each preset area range in the counterclockwise direction, since the area position angle γ is calculated, the angle range value of the first preset area range [0, 120 °) is obtained, and therefore, if the area position angle γ is 20 °, the viewing position angle of the user at the peripheral scene of the body 580 at the point S can be calculated to be 100 °. In other embodiments, if the image sensor is located in the second predetermined area range, since the angle value range of the second predetermined area range is [120 °, 240 °), if the area position angle corresponding to the included angle between the user and the viewing angle sideline oC is 20 °, at this time, the viewing position angle of the user at the point S in the peripheral scene of the body 580 is 220 °. In other embodiments, when the starting point of the viewing angle edge oA is 20 ° and the angle range value of each preset region range is set in the counterclockwise direction, the angle range value of the first preset region range [20 °, 140 °), if the region position angle γ is 20 °, the viewing position angle of the user at the peripheral scene of the body 580 at the point S can be calculated to be 120 °.

Therefore, when γ is 20 °, it can be calculated that the viewing position angle of the peripheral scene of the user at the body 580 at the point S is 100 °, and at this time, the viewing position angle of the peripheral scene of the user at the body 580 corresponds to the visual range of (10 °, 190 °). The preset length corresponding to the viewing position angle of the peripheral scene of the user located at the body 580 at the point S may be represented as:

according to the display control method, the position information of the user relative to the preset area range is obtained, the visual range of the user relative to the display screen is determined according to the position information, and the picture is controlled to be displayed on the area of the display screen corresponding to the visual range.

Referring to fig. 6, a flowchart illustrating steps of a display control method according to an embodiment of the present application is shown. The display control method includes the steps of:

and 200, controlling the image sensor to acquire an image in a preset area range relative to the body.

Step 202, judging whether the image contains human body features, if so, executing step 206; if not, go to step 204.

And step 204, executing a delay operation and returning to the step 200.

And when the image does not contain human body characteristics or other conditions, performing time delay operation, for example, after the preset time is prolonged, performing the control image sensor to acquire the image in the preset area range. In an embodiment, if the image does not include the human body feature, the delay time of the delay operation may be a first preset time.

And step 206, acquiring the position information of the user corresponding to the human body characteristics within the preset area range.

And step 208, determining the visual range of the user relative to the display screen according to the position information.

Step 210, judging whether an angle difference between an area corresponding to the visual range to be displayed on the display screen and an area of a current display picture of the display screen is greater than a preset angle value, if so, executing step 212; if not, the area of the current frame displayed on the display screen may not be adjusted, at this time, step 204 is executed to execute a delay operation, such as extending the second preset time, and then the step 200 is executed again after extending the second preset time.

In an embodiment, at the first time, the viewing position angle of the user located at the peripheral scene of the body 580 is 100 °, and the area of the currently displayed picture on the display screen of the electronic device may be determined to be (10 °, 190 °) according to fig. 3, that is, the first preset angle range is (10 °, 190 °); at the second time, if the viewing position angle of the peripheral scene of the body 580 at the position moved by the user is 130 °, at this time, it may be determined that the area corresponding to the visual range that needs to be displayed by the display screen of the electronic device is (30 °, 210 °), that is, the second preset angle range is (30 °, 210 °). Therefore, it can be determined that the angle difference between the area corresponding to the visual range that needs to be displayed on the display screen and the area of the currently displayed screen is 20 °. If the preset angle value is 10 degrees, it indicates that the angle difference between the area corresponding to the visual range displayed on the display screen and the area of the currently displayed picture is greater than the preset angle value, and at this time, the area of the currently displayed picture on the display screen needs to be adjusted. Therefore, a first preset angle range of an area where a current display picture on the display screen is located can be obtained first, a second preset angle range of the area which needs to be displayed on the display screen according to the position information control can also be obtained, and then whether the difference between the first preset angle range and the second preset angle range is larger than the preset angle value or not can be judged.

In an embodiment, a first center position of an area of a current display frame on the display screen may be obtained, a second center position of the area that needs to be displayed on the display screen according to the position information may be obtained, and then, whether an angle difference between the first center position and the second center position is greater than the preset angle value may be compared to determine. In this embodiment, the viewing position corresponding to the current display frame of the display screen may be represented according to the center position of the current display frame of the display screen. For example, when the display screen currently displays a preset angle range (10 ° and 190 °) of a picture, the first center position is 100 °; when the area displayed on the display screen is (30 degrees, 210 degrees) according to the position information, the second center position is 130 degrees. It can be seen that the angular difference between the first central position and the second central position is greater than the preset angular value by 10 °. At this time, it is necessary to adjust the area of the currently displayed screen on the display screen.

In an embodiment, when the angle difference between the area corresponding to the visual range displayed on the display screen and the area of the currently displayed picture is not greater than the preset angle value, it indicates that the user can still obtain better user experience for the currently displayed picture of the display screen.

And 212, controlling to display a picture on an area of the display screen corresponding to the visual range.

The display control method also determines whether to adjust the preset angle range of the current display picture by judging whether the value of the position of the current display picture of the adjustment display screen is larger than the preset angle value, so that when the position of the user in front of the electronic equipment is changed greatly, the position of the current display picture can be controlled timely to change along with the change of the position of the user, and the user experience is improved.
