Description

electronic device

The present disclosure relates to an electronic device.

It is known that some screens may contain a camera. The images captured by the camera are displayed on the screen. However, when the viewing angle of the display screen needs to be changed, it is usually adjusted through the setting function (eg, software program) of the screen itself. However, such a method of adjusting the field of view requires a relatively complicated process, for example, it takes some time to start the software to perform the operation, which is quite inconvenient.

The present disclosure relates to an electronic device that can improve the aforementioned conventional problems.

An embodiment of the present disclosure provides an electronic device. The electronic device includes a screen, a first shading plate, a first angle detector and a camera. The first shading plate is pivotally connected to the screen. The first angle detector is disposed on the first shading plate and used to detect a first angle of the first shading plate relative to the screen. The camera has a viewing angle setting, and the viewing angle setting is changed according to the first angle.

Another embodiment of the present disclosure provides an electronic device. The electronic device includes a flexible screen, an angle detector and a camera. The angle detector is arranged on the flexible screen to detect the bending degree of the flexible screen and output the corresponding bending One of the levels of detection signals. The camera has a viewing angle setting, and the viewing angle setting is changed according to the detection signal.

Another embodiment of the present disclosure provides an electronic device. The electronic device includes a screen, a first shading plate, a first angle detector and a camera. The screen has a display orientation. The first light-shielding plate is pivotally connected to one side of the screen, and a light-emitting device is arranged on the light-shielding plate to have a light-emitting range. The first angle detector is disposed on the first shading plate and used to detect a first angle of the first shading plate relative to the screen. The camera has a shooting direction that is the same as the display direction and is within the light output range. When the first angle becomes larger, the brightness of the illuminator increases.

FIG. 6 is a schematic diagram of an electronic device 20 according to another embodiment of the present invention.

Please refer to FIGS. 1 to 4. FIG. 1 shows a functional block diagram of an electronic device 10 according to an embodiment of the present invention, and FIGS. 2 to 4 show the electronic device of FIG. 1. A schematic diagram of the first light shielding plate 140 and/or the second light shielding plate 160 at several different angles. The electronic device 10 is, for example, a device including a light shield, such as a display notebook computer, a desktop computer, and a tablet computer.

The electronic device 10 includes a screen 110 , a camera 120 , a first angle detector 130 , a first shading plate 140 , a scaler 145 , a second angle detector 150 , a second shading plate 160 , a first light-emitting device The device 170 , the second light emitter 180 , the processor 190 and the driving mechanism 195 .

In one embodiment, the screen 110 , the camera 120 , the first angle detector 130 , the first shading plate 140 , the second angle detector 150 , the second shading plate 160 , the first light-emitting device 170 and the second light-emitting device The processor 180 can form a display 100A, and the processor 190 can be configured in the host 100B of the electronic device 10, wherein the display 100A and the host 100B can be pivotally connected to each other, or a transmission line (not shown) can be electrically connected between the display 100A and the host 100B connect. In another embodiment, the electronic device 10 itself may also be an independent display, that is, the processor 190 may be configured on the display 100A.

The first light shielding plate 140 is pivotally connected to the screen 110 . The first angle detector 130 is disposed on the first shading plate 140 and used to detect the first angle A1 of the first shading plate 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 can be manually adjusted manually. Compared with the settings of the conventional manual operation of the display itself (eg, On-Screen Display, OSD) or software program (APP)), the operation of the first visor 140 is faster and more convenient. The rotation of the first light-shielding plate 140 is, for example, a stepless rotation (eg, can be rotated continuously), so it can quickly respond to the setting of the viewing angle of the camera 120 . 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 configured on the screen 110 . The processor 190 can change the field angle setting ST of the camera 120 through the scaler 145 . For example, the scaler 145 is used to: (1) provide a setting interface SE1 for a viewing angle adjustment mode; and, (2) respond to the starting command T1 of the viewing angle adjustment mode received by the setting interface SE1, and start Field of view adjustment mode. When the viewing angle adjustment mode is activated, the processor 190 changes the viewing angle setting ST of the camera 120 in response to the angle of the visor. When the FOV adjustment mode is turned off (eg, disabled), the processor 190 does not respond to the change of the angle of the visor (ie, does not change the FOV setting ST of the camera 120 ), so that the processor 190 can be reduced burden.

The first angle detector 130 can be disposed on the first shading plate 140 and the pivot shaft 115 of the screen 110 to detect the movement of the pivot shaft 115 and then detect the angle of the first shading plate 140 . In one embodiment, the first angle detector 130 is, for example, a variable resistor, a Hall sensor, or other sensors that can detect the movement angle of an object. When the first shading plate 140 and the screen 110 rotate relative to each other, the first angle detector 130 can output a detection signal S1. The processor 190 can analyze the detection signal S1 to obtain the first angle A1. In another embodiment, depending on the type of the first angle detector 130 , the first angle detector 130 can calculate the first angle A1 according to the detection signal S1 and output the first angle A1 to the processor 190 .

In one embodiment, as shown in FIG. 2 , when the number of subjects in the imaging range C1 increases or increases and/or the volume of the subjects becomes larger or larger, the first angle A1 can be adjusted to be larger. (such as changing from the angle shown in Fig. 2 to the angle shown in Fig. 4), to increase the field of view of the camera 120 to set ST, so that the imaging range C1 can be expanded, allowing more subjects to enter the imaging range C1 and let the light emitted by the display surface 110u enter the imaging range C1 to improve the imaging quality. In another embodiment, when there are fewer or fewer subjects in the imaging range C1 and/or the volume of the subject is smaller or smaller, the first angle A1 can be reduced (as shown in FIG. 4 ) The angle is changed to the angle shown in FIG. 2 ) to reduce the field of view of the camera 120 and set ST, and at the same time concentrate the light emitted by the display surface 110u to match the actual situation.

The imaging range C1 shown in the figure is only for illustration, and its actual range is, for example, a cone-shaped range perpendicular to the lens 121 of the camera 120 .

The aforementioned subject 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 the shooting environment, such as a background object of the user's environment. Of course, as long as the subject that enters the imaging range C1 belongs to the subject in this application.

The second angle detector 150 is disposed on the second shading plate 160 and used to detect the second angle A2 of the second shading plate 160 relative to the screen 110 . The field of view setting ST of the camera 120 can be changed according to the first angle A1 and/or the second angle A2, so that the field of view setting of the camera 120 can be changed by changing the first angle A1 and/or the second angle A2 st. In one embodiment, when the sum of the first angle A1 and the second angle A2 is larger, the field angle setting ST of the camera 120 is larger; when the first angle A1 The smaller the sum with the second angle A2 is, the smaller the field angle setting ST of the camera 120 is. Alternatively, when one of the first angle A1 and the second angle A2 is larger, the field angle setting ST of the camera 120 is larger; when the one of the first angle A1 and the second angle A2 is smaller, the camera 120 The smaller the angle of view ST is, the smaller it is.

The second angle detector 150 is, for example, a variable resistor, which is disposed on the second shading plate 160 and the pivot shaft 116 of the screen 110 . When the second shading 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 the 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 FIGS. 2 to 4 , at least one of the first light emitter 170 and the second light emitter 180 can emit light toward the imaging range C1 , which can make up for the insufficient light in the imaging range C1 to improve the shooting quality. For example, the first light emitting device 170 may be disposed on the first light shielding plate 140, and when the camera 120 is activated (eg, in an image-capable state), the first light emitting device 170 emits the first light L1. In this way, at least a part of the first supplementary light range P1 of the first light L1 can be located within the imaging range C1. The first light L1 of the first light-emitting device 170 can make up for the insufficient amount of light in the imaging range C1 to improve the imaging quality. Similarly, the second light-emitting device 180 may be disposed on the second light shielding plate 160 , and when the camera 120 is activated, the second light-emitting device 180 emits a second light L2 . In this way, at least a part of the second supplementary light range P2 of the second light L2 can be located within the imaging range C1. The second light L2 of the second light-emitting device 180 can make up for the insufficient light in the imaging range C1, to improve shooting quality. In addition, the first light-emitting device 170 and the second light-emitting device 180 are, for example, light-emitting diodes.

The first supplementary light range P1 shown in the figure is only for illustration, and its actual range is, for example, the actual light-emitting angle range (eg, cone range) of the first light beam L1 emitted from the light-emitting surface of the first light-emitting device 170 . Similarly, the second supplementary light range P2 shown in the figure is only schematic, and its actual range is, for example, the actual light-emitting angle range of the second light beam L2 emitted from the light-emitting surface of the second light-emitting device 180 .

In one embodiment, the processor 190 may control the light intensity of the light emitted by the first light-emitting device 170 and/or the second light-emitting device 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 stronger or stronger brightness and/or when the second angle A2 is larger or larger , the processor 190 can control the second light-emitting device 180 to emit the second light L2 with stronger or stronger brightness. On the contrary, 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 processing The device 190 can control the second light emitter 180 to emit the second light L2 with weaker or weaker brightness.

In another embodiment, the processor 190 can also control the light intensity of the light emitted by the first light-emitting device 170 and/or the second light-emitting device 180 according to the content of the frame M1 captured by the camera 120 . The picture M1 is, for example, a dynamic picture, such as a live streaming dynamic image, or a static picture, such as at least one photo. The processor 190 may use an image analysis technology to analyze the proportion of the subject (eg, human face) of the content of the frame M1 captured by the camera 120 to the entire frame. When the proportion is equal to or less than a preset proportion At this time, the first light-emitting device 170 and/or the second light-emitting device 180 increase the light intensity of the light emitted, so as to obtain a shooting image with better shooting quality. When the ratio is greater than the preset ratio, the first illuminator 170 and/or the second illuminator 180 can reduce the light intensity of the light emitted, so as to save power and avoid capturing too much light and taking overexposed photos. In one embodiment, the aforementioned preset ratio is, for example, any value equal to or greater than 50%, such as 60%, 70%, 80%, 90%, and the like.

In addition, the processor 190 is further configured to: (1) determine whether the subject in the frame M1 conforms to a specific target according to the content of the frame M1 captured by the camera 120; (2). When the photographed object meets a specific target, the setting ST of the field of view of the camera 120 is changed according to the first angle A1 and/or the second angle A2. In this way, the processor 190 can filter the characteristics of the subjects entering the imaging range C1, and only the subjects that meet the specific target enter the imaging range C1, and then consider whether to change the field angle setting ST of the camera 120. In one embodiment, the specific target is, for example, a human body (eg, a member participating in a video conference), and only if the human body enters the imaging range C1, it is considered to change the field angle setting ST of the camera 120 .

In another embodiment, the electronic device 10 may selectively omit the aforementioned 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 shading plate 140 and used to rotate the first shading plate 140 to change the first angle A1 . Similarly, the driving mechanism 195 is connected to the second light shielding plate 160 and used to rotate the second light shielding plate 160 to change the second angle A2. The processor 190 can control the driving mechanism 195 to drive the first shading plate 140 and/or the second shading plate 160 to rotate to change the first angle A1 and/or the second angle A2. The driving mechanism 195 is, for example, a motor, but the embodiment of the present invention is not limited thereto. In another embodiment, the electronic device 10 may selectively omit the driving mechanism 195 .

Please refer to FIG. 5 , which is a schematic diagram of an electronic device 20 according to another embodiment of the present invention. The electronic device 20 includes a screen 110, a camera 220, a first angle detector 130, a first shading plate 140, a scaler 145 (not shown), a second angle detector 150, a second shading plate 160, a first A light-emitting device 170, a second light-emitting device 180, a processor 190 and/or a driving mechanism 195 (not shown).

The electronic device 20 of the embodiment of the present 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 according to the angle of the visor. Specifically, 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 with the imaging direction. The processor 190 is used for: controlling the lens 221 of the camera 220 to be inclined 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 light shielding plate 140 relative to the screen 110 is greater than the second angle A2 of the second light shielding plate 160 relative to the screen 110 (indicating that the subject may be biased towards the first light shielding plate 140 ) area), the processor 190 can control the shooting direction of the lens 221 of the camera 220 to deflect (as shown by the left arrow in FIG. 5 ) to the first light shielding plate 140 . In one embodiment, the deflection angle of the shooting direction of the lens 221 may be proportional to the angle value of the largest one of the first angle A1 and the second angle A2. For example, as shown in FIG. 5 , when the first angle A1 is larger, the shooting direction of the lens 221 is more inclined to the first light shielding plate 140 .

In one embodiment, the screen 110 has a display orientation (eg, approximately is perpendicular to the direction of the display surface 110u (shown in FIG. 2 ) of the screen 110 . The first shading plate 140 can be pivotally connected to one side of the screen 110 , and a first light emitting device 170 is disposed on the first shading plate 140 , which has a light output range (eg, a first fill light range P1 ). The first angle detector 130 is disposed on the first shading plate 140 and used to detect the first angle A1 of the first shading plate 140 relative to the screen 110 . The camera 120 has a shooting direction (eg, a shooting range C1 ) that is the same as the display direction and within the light output range of the first light-emitting device 170 . When the first angle A1 increases, the brightness of the first light-emitting device 170 increases. Similarly, the second shading plate 160 can be pivotally connected to the other opposite side of the screen 110 , and the second light emitting device 180 is disposed on the second shading plate 160 , which has a light emission range (eg, a second supplementary light range P2 ). The second angle detector 150 is disposed on the second shading plate 160 and used to detect the second angle A2 of the second shading plate 160 relative to the screen 110 . The shooting direction of the camera 120 is the same as the display direction and within the light output range of the second light-emitting device 180 , when the second angle A2 increases, the brightness of the second light-emitting device 180 increases.

Please refer to FIG. 6 , which is a schematic diagram of an electronic device 30 according to another embodiment of the present invention. The electronic device 30 includes a flexible screen 310 , a camera 320 , at least one angle detector 330 , a first light-emitting device 370 , a second light-emitting device 380 , and a processor 190 . The angle detector 330 can be disposed on the flexible screen 310 for detecting the degree of bending of the flexible screen 310 and outputting a detection signal S1 corresponding to the degree of bending. The camera 320 has a viewing angle setting ST (not shown in FIG. 6 ), and the viewing angle setting ST is changed according to the detection signal S1 . In this way, the field angle setting ST of the camera 320 can be changed by changing the first angle A1.

The aforementioned “bending degree” is, for example, at least one of the flexible screen 310 The bending angle or curvature of the part.

Camera 320 may have at least one feature similar or identical to camera 120 or 220 previously described. 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 and the bending degree of the second side 312 of the flexible screen 310 are different, 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 degree of curvature of the first side of the flexible screen 310 is greater than the degree of curvature of the second side 312 of the flexible screen 310 , the camera 320 changes the shooting direction of its lens 321 toward the first side of the flexible screen 310 . side.

The flexible screen 310 has an opposite display surface 310u and a back surface 310b. The angle detector 330 can be disposed on the back surface 310b of the flexible screen 310, for example. The embodiment of the present invention does not limit the disposition position of the angle detector 330, for example, it can be disposed in the middle position of the back surface 310b, or, the two sides of an angle detector 330 can respectively extend to the corresponding first side 311 and the second side 312 location. In another embodiment, a plurality of angle detectors 330 may be disposed at positions corresponding to the first side 311 and the second side 312 in the back surface 310b, respectively. In addition, the angle detector 330 is, for example, a variable resistor, a flex sensor or other sensors capable of detecting the bending of the flexible screen 310 .

The processor 190 can be electrically connected to the flexible screen 310 , the camera 320 , the angle detector 330 , the first light-emitting device 370 and the second light-emitting device 380 .

The processor 190 can analyze the detection signal S1 to obtain a flexible screen 310 degree of bending. In another embodiment, depending on the type of the angle detector 330, the angle detector 330 itself can calculate the degree of bending of the flexible screen 310 according to the detection signal S1, and output a signal representing the degree of bending 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-emitting device 370 and the second light-emitting device 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-emitting device 370 and the second light-emitting device 380 can emit light toward the imaging range C1 , which can make up for the insufficient amount of light in the imaging range C1 to improve the shooting quality. For example, the first light emitting device 370 may be disposed on the flexible screen 310, and when the camera 320 is activated (eg, in an image-capable state), the first light emitting device 370 emits the first light L1. In this way, at least a part of the first supplementary light range P1 of the first light L1 can be located within the imaging range C1. The first light L1 of the first light-emitting device 370 can make up for the insufficient amount of light in the imaging range C1 to improve the imaging quality. Similarly, the second light emitting device 380 can be disposed on the flexible screen 310. When the camera 320 is activated, the second light emitting device 380 emits a second light L2. In this way, at least a part of the second supplementary light range P2 of the second light L2 can be located within the imaging range C1. The second light L2 of the second light emitting device 380 can make up for the insufficient amount of light in the imaging range C1, so as to improve the imaging quality.

In one embodiment, the processor 190 can control the light intensity of the light emitted by the first light-emitting device 370 and/or the second light-emitting device 380 according to the degree of bending of the flexible screen 310 . For example, when the bending degree of the first side 311 of the flexible screen 310 becomes 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 The first light emitter 370 can be controlled to emit strong brightness or the stronger first light L1 and/or when the bending degree of the second side 312 of the flexible screen 310 becomes smaller or smaller (meaning that the angle between the second side 312 and the middle of the flexible screen 310 is larger or increase), the processor 190 may control the second light emitter 380 to emit the second light L2 with stronger or stronger brightness. Conversely, when the bending degree of the first side 311 of the flexible screen 310 is larger or larger (meaning that the angle between the first side 311 and the middle of the flexible screen 310 is smaller or smaller), the processor 190 The first light-emitting device 370 can be controlled to emit the first light L1 with weaker or weaker brightness and/or when the bending degree of the second side 312 of the flexible screen 310 is larger or larger (indicating that the second side 312 and the flexible When the angle between the two screens 310 is smaller or smaller), the processor 190 can 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 intensity of the light emitted by the first light-emitting device 370 and/or the second light-emitting device 380 according to the content of the frame M1 captured by the camera 320 . The picture M1 is, for example, a dynamic picture, such as a live streaming dynamic image, or a static picture, such as at least one photo. The processor 190 can use an image analysis technology to analyze the proportion of the subject in the content of the frame M1 captured by the camera 320 to the entire frame. When the ratio is equal to or smaller than a predetermined ratio, the first light emitter 370 and/or the second light emitter 380 increase the light intensity of the light emitted, so as to obtain a shooting image with better shooting quality. When the ratio is greater than the preset ratio, the first light-emitting device 370 and/or the second light-emitting device 380 can reduce the light intensity of the emitted light to save power. In one embodiment, the aforementioned preset ratio is, for example, any value equal to or greater than 50%, such as 60%, 70%, 80%, 90%, and the like.

In addition, the processor 190 can be further used to: (1). According to the camera 320 The content of the captured frame M1 determines whether the subject in the frame M1 meets a specific target; (2). When the subject in the frame M1 meets the specific target, the field of view of the camera 320 is set ST The direction varies according to the degree of bending of the flexible screen 310 . In this way, the processor 190 can filter the characteristics of the subjects entering the imaging range C1 , and only the subjects that meet the specific target enter the imaging range C1 before considering whether to change the field angle setting ST of the camera 320 . In one embodiment, the specific target is, for example, a human body (eg, a member participating in a video conference), and only if the human body enters the imaging range C1, it is considered to change the field of view setting ST of the camera 320 .

In addition, the luminous intensity of the light emitter of the electronic device can be changed by at least one of the following methods: (1) the angle of the visor relative to the screen; (2) the content of the image captured by the camera; and/ Or (3). The degree of bending of the flexible screen. In one embodiment, the angle of the light-shielding plate relative to the screen can be controlled by a driving mechanism, but can also be controlled manually.
