It will be appreciated by those of ordinary skill in the art that manufacturers may refer to a component by different names. The description and claims do not take the form of an element differentiated by name, but rather by functional differences. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. In the description of the present invention, the terms "first," "second," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.
Referring to fig. 1 to 4, fig. 1 is a functional block diagram of an electronic device 10 according to an embodiment of the invention, and fig. 2 to 4 are schematic diagrams illustrating the first light shielding plate 140 and/or the second light shielding plate 160 of the electronic device 10 of fig. 1 at several different angles. The electronic device 10 is, for example, a display notebook computer, a desktop computer, a tablet computer, or the like, which includes a light shielding plate.
The electronic device 10 includes a screen 110, a camera 120, a first angle detector 130, a first mask 140, a scaler 145, a second angle detector 150, a second mask 160, a first light emitter 170, a second light emitter 180, a processor 190, and a driving mechanism 195.
In one embodiment, the screen 110, the camera 120, the first angle detector 130, the first mask 140, the second angle detector 150, the second mask 160, the first light emitter 170 and the second light emitter 180 may form a display 100A, and the processor 190 may be disposed on a host 100B of the electronic device 10, wherein the display 100A and the host 100B may be coupled to each other, or a transmission line (not shown) may be electrically connected between the display 100A and the host 100B. In another embodiment, the electronic device 10 itself may be a stand-alone display, i.e., the processor 190 may be configured with the display 100A.
The first light shielding plate 140 is pivoted to the screen 110. The first angle detector 130 is disposed on the first mask 140 and is used for detecting a first angle A1 of the first mask 140 relative to the screen 110. The camera 120 has a Field of View (FoV) setting, and the Field of View setting ST is changed according to the first angle A1. In this way, the field angle setting ST of the camera 120 can be changed by changing the first angle A1.
The first angle A1 may be manually adjusted by a human. The first mask 140 is faster and more convenient to operate than prior art manual Display settings (e.g., through On-Screen Display (OSD) or software program (APP)). The rotation of the first mask 140 is, for example, a stepless rotation (e.g., a continuous rotation), so that the setting of the angle of view of the camera 120 can be quickly responded to. In another embodiment, the first angle A1 can also be controlled by a driving mechanism, which will be described later.
The scaler 145 may be disposed at the screen 110. Processor 190 may change, via sealer 145, a field angle setting ST of camera 120. For example, the scaler 145 is to: (1) Providing a setting interface SE1 for a view angle adjustment mode; and (2) in response to the start command T1 of the angle adjustment mode received by the setting interface SE1, start the angle adjustment mode. When the angle adjustment mode is in the on state, the processor 190 changes the angle setting ST of the camera 120 in response to the angle of the mask. When the view angle adjustment mode is in an off state (e.g., disabled state), processor 190 does not respond to the angle change of the mask (i.e., does not change the view angle setting ST of camera 120), which may reduce the burden on processor 190.
The first angle detector 130 may be disposed between the first mask 140 and the pivot shaft 115 of the screen 110 to detect the movement of the pivot shaft 115, thereby detecting the angle of the first mask 140. In one embodiment, the first angle detector 130 is, for example, a variable resistor, a Hall sensor (Hall sensor), or other sensor capable of detecting the movement angle of the object. When the first mask 140 rotates relative to the screen 110, the first angle detector 130 outputs a detection signal S1. The processor 190 may analyze the detection signal S1 to obtain a first angle A1. In another embodiment, depending on the type of the first angle detector 130, the first angle detector 130 may calculate the first angle A1 according to the detection signal S1 and output the first angle A1 to the processor 190.
In an embodiment, as shown in fig. 2, when the number of the objects in the image capturing range C1 is larger or becomes larger and/or the volume of the objects is larger or becomes larger, the first angle A1 may be adjusted to be larger (e.g. from the angle shown in fig. 2 to the angle shown in fig. 4) to increase the view angle setting ST of the camera 120, so that the image capturing range C1 may be enlarged, more objects may enter the image capturing range C1, and the light emitted by the display surface 110u may enter the image capturing range C1 to improve the image capturing quality. In another embodiment, when the subject in the imaging range C1 is smaller or smaller and/or the volume of the subject is smaller or smaller, the first angle A1 is adjusted (e.g. from the angle shown in fig. 4 to the angle shown in fig. 2) to reduce the view angle setting ST of the camera 120 and concentrate the light emitted from the display surface 110u to match the actual situation.
The illustrated imaging range C1 is only illustrative, and its actual range is, for example, a cone range perpendicular to the lens 121 of the camera 120.
The photographed object is, for example, a human body, an animal, and/or an object, wherein the human body is, for example, a user and/or at least one viewer, and the object is, for example, a background object of a photographing environment, such as a background object of an environment in which the user is located. However, the subject entering the imaging range C1 is a subject referred to herein.
The second angle detector 150 is disposed on the second light shielding plate 160 and is used for detecting a second angle A2 of the second light shielding plate 160 relative to the screen 110. The view angle setting ST of the camera 120 may be changed according to the first angle A1 and/or the second angle A2, such that the view angle setting ST of the camera 120 may be changed by changing the first angle A1 and/or the second angle A2. In one embodiment, the larger the sum of the first angle A1 and the second angle A2, the larger the view angle setting ST of the camera 120; the smaller the sum of the first angle A1 and the second angle A2, the smaller the field angle setting ST of the camera 120. Alternatively, as one of the first angle A1 and the second angle A2 is larger, the view angle setting ST of the camera 120 is larger; when one of the first angle A1 and the second angle A2 is smaller, the view angle setting ST of the camera 120 is smaller.
The second angle detector 150 is, for example, a variable resistor, and is disposed between the second mask 160 and the pivot shaft 116 of the screen 110. When the second light shielding plate 160 rotates relative to the screen 110, the second angle detector 150 outputs a detection signal S2. The processor 190 analyzes the detection signal S2 to obtain a second angle A2. In another embodiment, depending on the type of the second angle detector 150, the second angle detector 150 can calculate the second angle A2 according to the detection signal S2 and output the second angle A2 to the processor 190.
As shown in fig. 2 to 4, at least one of the first light emitter 170 and the second light emitter 180 can emit light toward the image capturing range C1, and can compensate for insufficient light quantity in the image capturing range C1 to improve the image capturing quality. For example, the first light emitter 170 may be disposed on the first light shielding plate 140, and the first light emitter 170 emits the first light L1 when the camera 120 is activated (e.g., in a state capable of capturing images). In this way, at least a portion of the first light supplementing range P1 of the first light ray L1 may be located within the image capturing range C1. The first light L1 of the first light emitter 170 can compensate for the insufficient light quantity in the image capturing range C1 to improve the image capturing quality. Similarly, the second light emitter 180 may be disposed on the second light shielding plate 160, and the second light emitter 180 emits the second light L2 when the camera 120 is started. In this way, at least a portion of the second light supplementing range P2 of the second light ray L2 may be located within the image capturing range C1. The second light L2 of the second light emitter 180 can compensate for the insufficient light quantity in the image capturing range C1, so as to improve the image capturing quality. The first light emitter 170 and the second light emitter 180 are, for example, light emitting diodes.
The illustrated first light supplementing range P1 is only illustrative, and its actual range is, for example, an actual light emitting angle range (e.g., a cone range) of the first light ray L1 emitted from the first light emitter 170. Similarly, the illustrated second light supplementing range P2 is only illustrative, and the actual range thereof is, for example, the actual light emitting angle range of the second light ray L2 emitted from the second light emitter 180.
In one embodiment, the processor 190 may control the light intensity of the light emitted by the first light emitter 170 and/or the second light emitter 180 according to the first angle A1 and/or the second angle A2. For example, when the first angle A1 is larger or larger, the processor 190 may control the first light emitter 170 to emit the first light L1 with a stronger or stronger brightness and/or when the second angle A2 is larger or larger, the processor 190 may control the second light emitter 180 to emit the second light L2 with a stronger or stronger brightness. Conversely, when the first angle A1 is smaller or smaller, the processor 190 may control the first light emitter 170 to emit the first light L1 with weaker or weaker brightness and/or when the second angle A2 is smaller or smaller, the processor 190 may control the second light emitter 180 to emit the second light L2 with weaker or weaker brightness.
In another embodiment, the processor 190 may also control the light intensity of the light emitted by the first light emitter 170 and/or the second light emitter 180 according to the content of the frame M1 captured by the camera 120. The frame M1 is, for example, a dynamic frame such as a real-time streaming video or a static frame such as at least one photo. The processor 190 may analyze the proportion of the subject (e.g., face) of the content of the frame M1 captured by the camera 120 to the whole frame using image analysis technology. When the duty ratio is equal to or smaller than a predetermined ratio, the first light emitter 170 and/or the second light emitter 180 increase the light intensity of the emitted light to obtain a better shooting picture. When the duty ratio is greater than the predetermined ratio, the first light emitter 170 and/or the second light emitter 180 can reduce the light intensity of the emitted light, so as to save electric energy and prevent the light capturing from taking too strongly an excessively exposed picture. In one embodiment, the predetermined ratio is, for example, any value equal to or greater than 50%, such as 60%, 70%, 80%, 90%, etc.
In addition, processor 190 may be further configured to: (1) Judging whether the shot object in the picture M1 accords with a specific target according to the content of the picture M1 captured by the camera 120; (2) When the subject in the screen M1 meets the specific target, the view angle setting ST of the camera 120 changes according to the first angle A1 and/or the second angle A2. In this way, the processor 190 can screen the features of the subject that enters the imaging range C1, and only the subject that meets the specific target enters the imaging range C1, taking into consideration whether or not to change the view angle setting ST of the camera 120. In one embodiment, the specific target is, for example, a human body (e.g., a member participating in a video conference), and only the human body enters the imaging range C1, the user considers changing the view angle setting ST of the camera 120.
In another embodiment, the electronic device 10 may optionally omit the second angle detector 150, the second light shielding plate 160 and the second light emitter 180.
As shown in fig. 1, the driving mechanism 195 is connected to the first light shielding plate 140 and is used for rotating the first light shielding plate 140 to change the first angle A1. Similarly, the driving mechanism 195 is connected to the second light shielding plate 160 and is used to rotate the second light shielding plate 160 to change the second angle A2. The processor 190 may control the driving mechanism 195 to drive the first light shielding plate 140 and/or the second light shielding plate 160 to rotate to change the first angle A1 and/or the second angle A2. The drive mechanism 195 is, for example, a motor, although embodiments of the invention are not limited in this regard. In another embodiment, the electronic device 10 may optionally omit the drive mechanism 195.
Referring to fig. 5, a schematic diagram of an electronic device 20 according to another embodiment of the invention is shown. The electronic device 20 includes a screen 110, a camera 220, a first angle detector 130, a first mask 140, a scaler 145 (not shown), a second angle detector 150, a second mask 160, a first light emitter 170, a second light emitter 180, a processor 190, and/or a driving mechanism 195 (not shown).
The electronic device 20 according to the embodiment of the invention has the same or similar technical features as the electronic device 10, except that the shooting direction of the lens 221 of the camera 220 of the electronic device 20 can be adjusted along with the angle of the light shielding plate. In detail, the camera 220 can change the shooting direction of the lens 221 of the camera 120 according to the difference between the first angle A1 and the second angle A2. The imaging range C1 may vary depending on the imaging direction. Processor 190 is configured to: the lens 221 of the camera 220 is controlled to be biased to the largest of the first angle A1 and the second angle A2. For example, as shown in fig. 5, the first angle A1 of the first mask 140 relative to the screen 110 is greater than the second angle A2 of the second mask 160 relative to the screen 110 (indicating that the subject may be deflected to the area of the first mask 140), and the processor 190 may control the direction of the lens 221 of the camera 220 to deflect to the first mask 140 (as shown by the left arrow in fig. 5). In an embodiment, the deflection angle of the shooting direction of the lens 221 may be proportional to the angle value of the largest of the first angle A1 and the second angle A2. For example, as shown in fig. 5, the larger the first angle A1 is, the more the photographing direction of the lens 221 is biased toward the first shielding plate 140.
In one embodiment, the screen 110 has a display direction (e.g., a direction substantially perpendicular to a display surface 110u (shown in fig. 2) of the screen 110). The first light-shielding plate 140 may be pivoted to a side of the screen 110, and a first light emitter 170 is disposed on the first light-shielding plate 140 and has a light-emitting range (e.g., a first light-compensating range P1). The first angle detector 130 is disposed on the first mask 140 and is used for detecting a first angle A1 of the first mask 140 relative to the screen 110. The camera 120 has a shooting direction (e.g., shooting range C1) identical to the display direction and is within the light emitting range of the first light emitter 170, and when the first angle A1 becomes larger, the brightness of the first light emitter 170 increases. Similarly, the second light-shielding plate 160 may be pivoted to the other opposite side of the screen 110, and the second light-emitting device 180 is disposed on the second light-shielding plate 160 and has a light-emitting range (e.g., a second light-compensating range P2). The second angle detector 150 is disposed on the second light shielding plate 160 and is used for detecting a second angle A2 of the second light shielding plate 160 relative to the screen 110. The photographing direction of the camera 120 is the same as the display direction and within the light emitting range of the second light emitter 180, when the second angle A2 becomes large, the brightness of the second light emitter 180 increases.
Referring to fig. 6, a schematic diagram of an electronic device 30 according to another embodiment of the invention is shown. The electronic device 30 includes a flexible screen 310, a camera 320, at least one angle detector 330, a first light emitter 370, a second light emitter 380, and a processor 190. The angle detector 330 is disposed on the flexible screen 310 for detecting the bending degree of the flexible screen 310 and outputting a detection signal S1 corresponding to the bending degree. The camera 320 has a field angle setting ST (not shown in fig. 6), which is changed according to the detection signal S1. Thus, the view angle setting ST of the camera 320 can be changed by changing the first angle A1.
The "bending degree" is, for example, a bending angle or a curvature of at least a portion of the flexible screen 310.
The camera 320 may have at least one feature similar or identical to the cameras 120 or 220 described above. The camera 320 can change the shooting direction of the lens 321 of the camera 320 according to the detection signal S1. For example, when the bending degree of the first side 311 of the flexible screen 310 is different from the bending degree of the second side 312 of the flexible screen 310, the shooting direction of the lens 321 of the camera 320 is changed. The first side 311 and the second side 312 are opposite sides of the flexible screen 310. For example, when the first side of the flexible screen 310 is bent to a greater extent than the second side 312 of the flexible screen 310, the camera 320 changes the shooting direction of the lens 321 to be biased toward the first side of the flexible screen 310.
The flexible screen 310 has a display surface 310u and a back surface 310b opposite to each other. The angle detector 330 may be disposed on the back surface 310b of the flexible screen 310, for example. The arrangement position of the angle detector 330 is not limited, and for example, the angle detector 330 may be arranged at the middle position of the back surface 310b, or two sides of one angle detector 330 may extend to positions corresponding to the first side 311 and the second side 312, respectively. In another embodiment, the plurality of angle detectors 330 may be disposed at positions corresponding to the first side 311 and the second side 312 of the back surface 310b, respectively. In addition, the angle detector 330 is, for example, a variable resistor, a flex sensor (flex sensor) or other sensor that can detect the bending of the flexible screen 310.
Processor 190 may be electrically connected to flexible screen 310, camera 320, angle detector 330, first light emitter 370, and second light emitter 380.
Processor 190 may analyze detection signal S1 to obtain a degree of bending of flexible screen 310. In another embodiment, depending on the type of the angle detector 330, the angle detector 330 itself can calculate the bending degree of the flexible screen 310 according to the detection signal S1 and output a signal indicating the bending degree to the processor 190. In addition, the processor 190 may analyze the frame M1 captured by the camera 320.
As shown in fig. 6, the first light emitter 370 and the second light emitter 380 are disposed adjacent to the first side 311 and the second side 312 of the flexible screen 310, respectively. At least one of the first light emitter 370 and the second light emitter 380 can emit light toward the image capturing range C1, and can compensate for insufficient light quantity in the image capturing range C1 to improve the image capturing quality. For example, the first light emitter 370 may be disposed on the flexible screen 310, and the first light emitter 370 emits the first light L1 when the camera 320 is activated (e.g., in a camera-enabled state). In this way, at least a portion of the first light supplementing range P1 of the first light ray L1 may be located within the image capturing range C1. The first light L1 of the first light emitter 370 can compensate for insufficient light quantity in the image capturing range C1 to improve the image capturing quality. Similarly, the second light emitter 380 may be disposed on the flexible screen 310, and when the camera 320 is activated, the second light emitter 380 emits a second light L2. In this way, at least a portion of the second light supplementing range P2 of the second light ray L2 may be located within the image capturing range C1. The second light L2 of the second light emitter 380 can compensate the insufficient light quantity in the image capturing range C1 to improve the image capturing quality.
In one embodiment, processor 190 may control the intensity of light emitted by first light emitter 370 and/or second light emitter 380 according to a degree of bending of flexible screen 310. For example, when the degree of curvature of the first side 311 of the flexible screen 310 is smaller or smaller (indicating that the angle between the first side 311 and the middle of the flexible screen 310 is larger or larger), the processor 190 may control the first light emitter 370 to emit the first light L1 with a stronger or stronger brightness and/or when the degree of curvature of the second side 312 of the flexible screen 310 is smaller or smaller (indicating that the angle between the second side 312 and the middle of the flexible screen 310 is larger or larger), the processor 190 may control the second light emitter 380 to emit the second light L2 with a stronger or stronger brightness. Conversely, when the degree of bending of the first side 311 of the flexible screen 310 is greater or greater (indicating that the angle between the first side 311 and the middle of the flexible screen 310 is smaller or smaller), the processor 190 may control the first light emitter 370 to emit the first light L1 with weaker or weaker brightness and/or when the degree of bending of the second side 312 of the flexible screen 310 is greater or greater (indicating that the angle between the second side 312 and the middle of the flexible screen 310 is smaller or smaller), the processor 190 may control the second light emitter 380 to emit the second light L2 with weaker or weaker brightness.
In another embodiment, the processor 190 is further configured to control the light intensity of the light emitted by the first light emitter 370 and/or the second light emitter 380 according to the content of the frame M1 captured by the camera 320. The frame M1 is, for example, a dynamic frame such as a real-time streaming video or a static frame such as at least one photo. The processor 190 may analyze the proportion of the subject in the content of the frame M1 captured by the camera 320 to the whole frame using image analysis technology. When the duty ratio is equal to or smaller than a predetermined ratio, the first light emitter 370 and/or the second light emitter 380 increases the light intensity of the emitted light to obtain a better shooting picture. When the duty ratio is greater than the predetermined ratio, the first light emitter 370 and/or the second light emitter 380 can reduce the light intensity of the emitted light to save electric energy. In one embodiment, the predetermined ratio is, for example, any value equal to or greater than 50%, such as 60%, 70%, 80%, 90%, etc.
In addition, processor 190 may be further configured to: (1) Judging whether the shot object in the picture M1 accords with a specific target according to the content of the picture M1 captured by the camera 320; (2) When the subject in the screen M1 meets the specific target, the view angle setting ST of the camera 320 changes according to the bending degree of the flexible screen 310. In this way, the processor 190 can screen the features of the subject that enters the imaging range C1, and only the subject that meets the specific target enters the imaging range C1, taking into consideration whether or not to change the view angle setting ST of the camera 320. In one embodiment, the specific target is, for example, a human body (e.g., a member participating in a video conference), and only the human body enters the imaging range C1, the user considers changing the view angle setting ST of the camera 320.
In summary, an embodiment of the present invention provides an electronic device that can change the view angle setting of a camera by at least one of the following ways: (1) the angle of the mask relative to the screen; (2) the content of the picture captured by the camera; and/or (3) the bending degree of the flexible screen. Furthermore, the luminous intensity of the light emitter of the electronic device may be varied by at least one of the following means: (1) the angle of the mask relative to the screen; (2) the content of the frame captured by the camera; and/or (3) the bending degree of the flexible screen. In one embodiment, the angle of the mask relative to the screen may be controlled by a drive mechanism, but may also be controlled manually.
