Description

Computer device and method of operating the same

The present invention relates to a computer device, and in particular to a computer device with a rotatable lens.

The laptop lens can be used for video. However, the angle of the camera is usually fixed, which causes hackers to peek into the user's privacy by controlling the camera during an intrusion, causing security issues.

In addition, instead of entering an account and password, facial features in the image can be captured through the camera and identified to assist users in automatically logging into the system. However, the prerequisite for the above action is that the user must open the closed laptop and adjust the angle between the monitor of the laptop and the desktop so that the lens is facing the user. Therefore, using the camera to capture the pre-action of automatic login is not convenient enough for users.

Therefore, it is necessary to provide a solution that can take into account information security and convenience.

The present invention provides a computer device that can take into account both information security and convenience.

The invention provides a computer device, which has a display and a host that are pivotally connected to each other. Computer devices include lenses, actuators, sensors, and control modules. The lens is rotatably disposed on the first side of the display. The actuator is coupled to the lens. The actuator is driven to rotate the lens. The sensor is disposed on the host computer and is used for performing object sensing actions to generate sensing signals. The control module is coupled to the lens, actuator and sensor. The control module is used to drive the actuator to rotate the lens according to the sensing signal, and enable the lens to shoot.

The invention provides an operating method of a computer device, wherein the computer device has a display and a host that are pivotally connected to each other, and the lens is arranged on the first side of the display. The operating method of the computer device includes: when the display and the host are in a closed state, the sensor provided on the host performs an object sensing action to generate a sensing signal; and the control module of the computer device generates a first signal based on the sensing signal. The control signal and the second control signal; the actuator coupled to the lens is driven according to the first control signal to drive the lens to deviate from a predetermined angle from the first direction; and the lens shoots according to the second control signal to obtain the first image frame . In the closed state, the lens faces the first direction by default.

Based on the above, the present invention can drive the actuator according to the sensing signal to rotate the lens and enable the lens to shoot. Furthermore, when the computer device is in a closed state, the user can be photographed by rotating the lens and the captured image can be Image recognition. In this way, the user login action can be automatically executed and it is convenient to use. On the other hand, since the lens is facing the first direction by default, the problem of hackers snooping into the user's privacy through the lens can be avoided.

FIG. 1 is a schematic diagram of the appearance of the computer device of the present invention. Referring to FIG. 1 , the display 1 of the computer device 100 is pivotally connected to the host 2 through a pivot shaft. The display 1 may be a liquid crystal display (Liquid-Crystal Display, LCD), a sub-millimeter light-emitting diode (Mini LED) display, or an organic light-emitting diode (OLED) display. The host 2 includes a motherboard, a processor, a memory, ... and an input and output device. From the outside, the computer device 100 also includes a lens 1a, an actuator 1b, a lens mount 1c, an indicator light 2a and a sensor 2b. In this embodiment, the computer device 100 may be a notebook computer.

FIG. 2 is a schematic diagram of the rotation direction of the lens of the present invention. Please refer to Figures 1 and 2 at the same time. The lens 1a is rotatably disposed on the side of the display 1 away from the pivot axis (hereinafter referred to as the "first side of the display"). As shown in FIG. 2, the lens 1a can rotate from facing the first direction D1 to facing the second direction D2. The first direction D1 and the second direction D2 are both normal directions perpendicular to the surface of the display 1 , and the first direction D1 is opposite to the second direction D2. In order to describe in an intuitive manner, the following text and figures will use "180 degrees" to indicate that the lens 1a faces the first direction D1, and "0 degrees" will indicate that the lens 1a faces the second direction D2. In this embodiment, the lens 1a can at least rotate between 180 degrees and 0 degrees. However, the present invention is not limited to this. In other embodiments, the lens 1a can rotate in other angle ranges.

The actuator 1b and the lens fixing bracket 1c are disposed on the first side of the display 1 and respectively located at both ends of the lens 1a. The actuator 1b is coupled to the lens 1a and is used to be driven to drive the lens 1a to rotate between 0 degrees and 180 degrees. In this embodiment, actuator 1b Including but not limited to micro motors, AC motors, DC motors, stepper motors and other electronic components that have the function of driving the lens to rotate. The lens holder 1c is coupled to the lens 1a for fixing the lens 1a and allowing the lens 1a to rotate around an axis. The indicator light 2a draws attention by emitting light continuously or intermittently. The sensor 2b is disposed on the side of the main unit 2 away from the pivot axis (hereinafter referred to as the "first side of the main unit"). The sensor 2b faces outward to sense whether there is an object approaching the computer device 100 at a close range. The sensor 2b generates a sensing signal when it senses that an object is close to the computer device 100 . In an embodiment of the present invention, the sensor 2b may be a proximity sensor, and its sensing range is, for example, 27 degrees in front and extending in a cone range of 20 centimeters. However, the present invention is not limited to this. In other embodiments, the sensing range of the sensor 2b can also be 20 degrees in front and extend to a range of 30 centimeters in a cone range.

The actions of the lens 1a, the actuator 1b, the indicator light 2a and the sensor 2b can be controlled by a control module (not shown). The control module is coupled to the lens 1a, the actuator 1b, the indicator light 2a and the sensor 2b. The control module is used to wake up from the sleep mode according to the sensing signal generated by the sensor 2b, and drive the actuator 1b to rotate the lens 1a. The control module can be in sleep mode, wake-up mode, start-up mode, sensing mode, privacy mode or focus-tracking mode.

FIG. 3 is a block diagram of the computer device of the present invention. Referring to Figure 3, in addition to the aforementioned sensor 2b, control module 110, lens 1a, actuator 1b and indicator light 2a, the computer device 100 also has a built-in facial feature database 120. Referring to Figure 3, the sensor 2b is coupled to the control module 110 for sensing an object (for example, the user 101) at close range. When the sensor 2b senses that an object is approaching, it senses Test signal 102. After being awakened according to the sensing signal 102, the control module 110 generates the rotation signal 103 and the shooting signal 104. The actuator 1b is driven to rotate the lens 1a according to the rotation signal 103. The rotating lens 1a takes pictures based on the shooting signal 104.

FIG. 4A is a schematic diagram of lens rotation according to an embodiment of the present invention. Figure 4B is a schematic diagram of the image captured by the lens of Figure 4A. Please refer to FIG. 3 , FIG. 4A and FIG. 4B at the same time. When the computer device 100 is laid flat (for example, determined by a gravity sensor (G-sensor)) and the display 1 and the host 2 are in a closed state, the lens 1 a is preset. The ground faces 180 degrees. At this time, the control module 110 is in a sleep state, and the sensor 2b continues to sense to generate a sensing signal 102 when an object (such as the user 101) is sensed within the sensing range. When the control module 110 is awakened, the rotation signal 103 and the shooting signal 104 are generated. The actuator 1b is driven according to the rotation signal 103 to rotate the lens 1a from 180 degrees to 130 degrees, that is, rotated 50 degrees toward the object. However, the present invention should not be limited to this. In other embodiments, the lens 1a can also be rotated from 180 degrees to 120 degrees, 135 degrees or other angles. The lens 1a takes pictures according to the shooting signal 104. When the lens 1a is at 180 degrees, for example, image 401 can be captured, and when the lens 1a is at 130 degrees, for example, image 402 can be captured. It can be known from Figure 4B that after turning 130 degrees, the lens 1a can be facing the object. At the same time, the control module 110 can also generate a lighting signal 105. The indicator light 2a emits light intermittently (flashes once or several times) according to the lighting signal 105, thereby attracting the user's attention so that the user knows that the control module 110 enters the wake-up mode.

The control module 110 is also used to perform facial feature recognition based on the image frame 106 captured by the lens 1b to generate a recognition result 107. In this embodiment, the facial features The algorithm for feature recognition can be an algorithm for recognition based on facial feature points (feature-based). However, the present invention is not limited to this. In other embodiments, the algorithm for facial feature recognition can also be based on the entire face image (appearance-based), based on template (template-based), or using neural network ( neural network) or an algorithm that uses a support vector machine (SVM) for recognition. In addition, in this embodiment, the control module 110 has the ability to execute a facial feature recognition algorithm to perform facial feature recognition. In other embodiments, the control module 110 may also perform facial feature recognition through facial recognition software (such as Windows Hello).

In this embodiment, the control module 110 performs comparison in the facial feature database 120 according to the recognition result 107 to generate the comparison result 108. The facial feature database 120 pre-stores at least one piece of facial feature information and a corresponding user account. The control module 110 may decide whether to initiate the user login process based on the comparison result 108 . When the comparison result 108 indicates that the recognition result 107 matches any piece of data in the facial feature database 120, the user account 130 is logged in (hereinafter referred to as "login successful"). After successful login, the control module 110 can control the lens to rotate back 180 degrees and stop shooting to save power. At the same time, the control module 110 can also generate a lighting signal 105 to cause the indicator light 2a of a specific color (such as green or blue) to emit light. On the contrary, when the comparison result 108 indicates that the recognition result 107 does not match all the data in the facial features 120, the user account 130 is not logged in (hereinafter referred to as "login failure"). At the same time, the control module 110 can also generate a lighting signal 105 to cause the indicator light 2a of a specific color (eg red) to emit light. Because the facial feature recognition algorithm and comparison process are not This is the key point of the present invention and therefore will not be described in detail.

In another embodiment of the present invention, the control module 110 determines whether the image frame 106 captured by the lens 1b contains a complete face image based on the recognition result 107. If the face image is incomplete, such as image 401, the sender can be adjusted to The rotation signal 103 to the actuator 1b is used to adjust the shooting angle of the lens 1a so that the image frame 106 includes a complete face image, such as image 402.

Table (1) lists the operating status of each component of the computer device 100 in the sleep mode, wake-up mode, successful login state after waking up, and failed login state after waking up, where "O" means that the corresponding component is in the activated state, and "X" means Indicates that the corresponding component is in a non-activated state.

In one embodiment, after the first login failure occurs in the closed state, the control module 110 can enable the sensor 2b to continue sensing. When the control module 110 continues to receive the sensing signal 102 within 10 seconds (or 20 seconds), it means that the person or object has not left the sensing range. At this time, the control module 110 sends a control signal to stop shooting (the lens 1a rotates to 180 degrees) and recognize the action. In one embodiment, after the first login failure occurs in the closed state and the object is sensed to disappear in the sensing range, and an object is sensed in the sensing range again, the control module 110 sends a control signal to start again. Shooting (for example, the lens 1a rotates from 180 degrees to 120 degrees, the lens 1 shoots according to the shooting signal 104), and the recognition action (for example, the control module 110 compares the facial feature database 120 according to the recognition result 107 to generate a comparison. Regarding the result 108), the detailed process will not be described here.

FIG. 5 is a flowchart of steps of the operating method in sleep mode and wake-up mode of the present invention. Please refer to Figure 4A and Figure 5 at the same time. First, it is determined whether the display 1 and the host 2 are in a closed state (step S510). If not, it means that the display 1 and the host 2 are in a rotationally open state. At this time, the control module is in the startup mode and the lens 1a is preset to face the first direction D1 (step S520). When the display 1 and the host 2 are closed, the control module is in the sleep mode and the lens 1a is preset to face the first direction D1 (step S530). At this time, the sensor 2b provided on the host 2 performs object sensing operation. When the control module receives the sensing signal (indicating that there is a sensor within the sensing range object is detected) (step S540), the control module enters the wake-up mode, and generates a first control signal and a second control signal according to the sensing signal (step S550). When the control module does not receive a sensing signal (indicating that no object is sensed within the sensing range), the control module remains in sleep mode. The actuator 1b coupled to the lens 1a receives the first control signal (ie, the aforementioned rotation signal) and is driven according to the first control signal to drive the lens 1a to deviate from the first direction by a predetermined angle (step S560). The second control signal (ie, the aforementioned shooting signal) is received by the lens 1a, and shooting is performed according to the second control signal to obtain the first image frame (step S570).

FIG. 6A is a schematic diagram of lens rotation according to an embodiment of the present invention. FIG. 6B is a schematic diagram of the image captured by the lens of FIG. 6A. FIG. 6C is a flowchart of steps of the operating method in the startup mode of the present invention. Please refer to FIG. 3 , FIG. 6A , FIG. 6B and FIG. 6C at the same time. First, it is determined whether the display and the host are in a rotation-on state (step S610 ). If not, it means that the display and the host are in a closed state. At this time, the control module 110 is in the sleep mode and the lens 1a is preset to face the first direction D1 (step S620). When the computer device 100 is laid flat and the display 1 and the host 2 are in a rotating open state, the control module 110 is in the startup mode. At this time, the lens 1a is preset to face 180 degrees (step S630). It is assumed that the user is operating the computer device 100 at this time and the sensor 2b continues to sense. When the control module 110 receives a sensing signal (indicating that an object is sensed within the sensing range) (step S640), the control module 110 generates a third control signal (rotation signal 103) and a fourth control signal based on the sensing signal. control signal (shooting signal 104) (step S650). The actuator 1b is driven according to the third control signal to rotate the lens 1a from 180 degrees (first direction D1) to 0 degrees (second direction D2) (step S660). The lens 1a receives the fourth control signal and shoots according to the fourth control signal (step S670). For example, image 601 can be captured when the lens 1a is at 180 degrees. For example, image 602 can be captured when the lens 1a is at 160 degrees. For example, image 603 can be captured when the lens 1a is at 40 degrees. For example, image 604 can be captured when the lens 1a is at 0 degrees. It can be known from Figure 6B that after turning to 0 degrees, the lens 1a can be facing the aforementioned object. At the same time, the control module 110 can also generate a lighting signal 105. The indicator lamp 2a emits light according to the lighting signal 105 (for example, causes a light signal of a specific color to emit light).

Similar to the previous one, the control module 110 can perform facial feature recognition based on the image frame 106 captured by the lens 1 b to generate a recognition result 107 . In this embodiment, the facial feature recognition algorithm may be a feature-based recognition algorithm. The control module 110 can perform comparison in the facial feature database 120 according to the recognition result 107 to generate a comparison result 108. The control module 110 can also decide whether to start the user login process based on the comparison result 108 .

Table (2) lists the operating status of each component of the computer device 100 in the startup mode, sensing mode, successful login state after sensing, and failed login state after sensing, where "O" indicates that the corresponding component is in the startup state, " "X" means that the corresponding component is in a non-activated state.

Table (2) In one embodiment, the control module 110 may also include a counter (not shown). The counter can count the accumulated number of failed logins. When the accumulated number reaches a threshold (for example, 5), the control module 110 sends a warning message 109 through, for example, the email 140 . The warning message 109 may include a warning message and a captured image 106 to remind the system administrator of a security event that the computer device has been attempted to log in multiple times by unauthorized users.

FIG. 7A is a flowchart of steps of the operating method in the privacy mode of the present invention. Please refer to FIG. 3 and FIG. 7A at the same time. When the computer device 100 is laid flat, it is determined whether the display 1 and the host 2 are in a rotating open state (step S710). If not, it means that the display 1 and the host 2 are in a closed state. At this time, the control module 110 is in the sleep mode and the lens 1a is preset to face the first direction D1 (step S520). If the rotation-on state is present, it is further determined whether the control module 110 is executing in the privacy mode (step S730). If the control module 110 does not execute the privacy mode, the control module 110 is in the activated state and the lens 1a is preset to face the first direction D1 (step S740). When the control module 110 is set by the user to enter the privacy mode, the control module 110 generates the fifth control signal (rotation signal 103) and the sixth control signal (photography signal 104) (step S750). The actuator 1b is driven according to the fifth control signal to drive the lens 1a to rotate from the first direction D1 to the second direction D2 (step S760). The lens 1a receives the sixth control signal and shoots according to the sixth control signal to obtain an image frame (step S770). Generally speaking, the privacy mode can be enabled when the user 701 is in an untrusted environment (such as a public place) or conducting video through the lens 1a.

Similarly, the image frame 106 is provided to the control module 110 for facial feature recognition. The control module 110 performs comparison in the facial feature database 120 based on the recognition result 107 and generates a comparison result 108 . When the comparison result 108 indicates that there is an unlogged user 702 in the image screen 106, a shielding action is performed on the display screen generated by the display 1 to prevent the displayed content from being snooped.

7B to 7D are schematic diagrams showing changes in the display screen according to an embodiment of the present invention. Please refer to FIG. 3 and FIG. 7B at the same time. In one embodiment, the control module 110 can determine the relative position of the unlogged user 702 in the image screen 106 through the recognition result 107 . After learning the relative position of the unlogged user 702, the control module 110 can dim the corresponding part of the display screen. The control module 110 sends a control signal to adjust a self-luminous display such as an organic light-emitting diode (OLED) display and a mini-LED display. The display’s polarizer module can achieve regional dimming. This can make it difficult for non-logged-in users 702 to see the displayed content clearly. In other embodiments, the entire display screen can also be dimmed.

Please refer to FIG. 3 and FIG. 7C at the same time. In one embodiment, the control module 110 can send a control signal to adjust the backlight module of the display (such as a liquid-crystal display (LCD)) to control all the displayed content. Reduce the brightness to achieve digital privacy protection. Please refer to FIG. 3 and FIG. 7D at the same time. In one embodiment, the control module 110 can send a control signal to execute the screen mask software, thereby blurring all the displayed content while maintaining the screen brightness.

Table (3) lists the operating status of each component of the computer device 100 in the privacy mode, where "O" indicates that the corresponding component is in an activated state, and "X" indicates that the corresponding component is in a non-activated state.

FIG. 8A is a flowchart showing the steps of the operating method in the focus tracking mode of the present invention. FIG. 8B is a schematic diagram of changes in the lower display screen according to an embodiment of the present invention. Please refer to FIG. 3 , FIG. 8A and FIG. 8B at the same time. First, it is determined whether the display 1 and the host 2 are in a rotationally open state (step S810 ). If not, it means that the display 1 and the host 2 are in a closed state. At this time, the control module 110 is in the sleep mode and the lens 1a is preset to face the first direction D1 (step S820). When the computer device 100 is laid flat and the display 1 and the host 2 are in a rotating open state, it is further determined whether the control module 110 is executing in the focus tracking mode (step S830). If the control module 110 does not execute the focus tracking mode, the control module 110 is in the activated state and the lens 1a is preset to face the first direction D1 (step S840). When the control module 110 is set by the user to enter the focus mode, the control module 110 generates the seventh control signal (rotation signal 103), the eighth control signal (capture signal 104) and the display signal (step S850). The actuator 1b receives the seventh control signal and is driven according to the seventh control signal to drive the lens 1a to rotate from the first direction D1 to the second direction D2 (step S860). The lens 1a receives the eighth control signal and shoots according to the eighth control signal to obtain an image frame 801 (step S860). The display receives the display signal to display the captured image frame 801 . Furthermore, the control module 110 can determine the position of the user's face in the image frame 106 to generate a focus signal. The lens 1a adjusts the focus of the image according to the focus signal. In an embodiment, the control module 110 can also digitally perform partial processing of the image frame 801. Magnify, and generate the image frame 802 by cropping the enlarged image frame. In one embodiment, when the user moves within the visual range of the lens 1a, the control module 110 can also generate the image frame 803 by enlarging and cropping the image frame 801. This creates the illusion that the camera is following the movement of the user.

Table (4) lists the operating status of each component of the computer device 100 in the focus tracking mode, where “O” indicates that the corresponding component is in an activated state, and “X” indicates that the corresponding component is in a non-activated state.

It should be noted that when the computer device 100 is closed and is not lying flat (for example, it is placed vertically in a backpack), the sensor 2b is not activated and the control module 110 In sleep mode to avoid sensing nearby objects and continuing to shoot and identify. Therefore, the prerequisite for the control module 110 to enter the wake-up mode, startup mode, sensing mode, privacy mode or focus mode is that the computer device 100 is laid flat. Whether the computer device 100 is laid flat can be determined through the gravity sensor (G-sensor) of the computer device 100 itself. In one embodiment, it is determined that the computer device 100 is placed flat when the angle between the host computer of the computer device 100 and the horizontal plane is between 0 and 60 degrees. In one embodiment, it is determined that the computer device 100 is placed flat when the angle between the host computer of the computer device 100 and the horizontal plane is between 0 and 45 degrees. In one embodiment, it is determined that the computer device 100 is placed flat when the angle between the host computer of the computer device 100 and the horizontal plane is between 0 and 20 degrees.

In addition, in terms of hardware, the control module is a logic circuit that can be implemented on an integrated circuit. The relevant functions of the control module can be implemented as hardware using hardware description languages (such as Verilog HDL or VHDL) or other suitable programming languages. For example, the related functions of the above control module can be implemented in one or more controllers, microcontrollers (micro control units, MCUs), microprocessors (microprocessors), graphics processing units (graphics processing units, GPUs) , image signal processor (ISP), image processing unit (IPU), arithmetic logic unit (ALU), complex programmable logic device (CPLD), central Processing unit (central processing unit, CPU), application-specific integrated circuit (ASIC), digital signal processor (DSP), field programmable logic gate array (Field Various logic blocks, modules and circuits in Programmable Gate Array (FPGA) and/or other processing units.

To sum up, when the computer device is in a closed state, the user can be photographed by rotating the lens and the captured image can be identified. Therefore, the user login action can be automatically executed without any prerequisite actions. Furthermore, when the user operates the computer device but does not activate the video, privacy mode and focus mode, the lens is oriented 180 degrees by default, thereby preventing hackers from snooping into the user's privacy through the lens. When executing privacy mode or focus tracking mode, you can control the lens from 180 degrees to 0 degrees. In this way, the present invention can take into account information security and ease of use.
