The processor is respectively connected with the camera module, the crystal oscillator, the serial port, the USB interface and the power module.

When the USB interface is connected with external equipment for supplying power, the power supply module for supplying power to the processor starts to be freely powered on, the crystal oscillator starts to work, and the system of the processor starts to be started. And when the system of the processor is started, the processor starts to send a control signal to the camera module according to the power-on time sequence of the image sensor in the camera module according to the internal configuration information of the processor. Meanwhile, the processor may also transmit a source clock signal, a reset signal, and register data of an image sensor in the camera module via an Inter-Integrated Circuit (I2C). When the image sensor in the camera module starts to work and acquires an image, the image can be output to a Processor through a Mobile Industry Processor Interface (MIPI).

The structure of the camera module is not limited in the embodiments of the present application, and in some embodiments, the camera module may include an image sensor, a lens, and a Voice Coil Motor (VCM) Motor.

However, in the current privacy protection scheme of the camera, neither the image sensor or the processor of the camera nor the processor of the accessed display device can determine the privacy protection state of the camera.

In order to solve the above problem, an embodiment of the present application provides a display device and a camera, where a detection circuit is disposed on the camera, and a position of a dial relative to a lens is detected in real time in a sliding process of the dial, so that a processor of the display device can determine a privacy protection state of the camera.

A schematic structural diagram of a provided camera according to some embodiments is illustrated in fig. 5. As shown in fig. 5, in addition to fig. 4, a detection circuit may be further disposed in the camera, and the detection circuit detects the position of the pick-up relative to the lens in real time and sends a position signal to a processor of the camera. Meanwhile, the privacy protection state of the camera is determined in real time based on the position of the shifting piece relative to the lens by further sending the privacy protection state to a processor of the display device through the processor of the camera.

The following first explains a paddle according to an embodiment of the present application.

The plectrum of camera that this application embodiment relates to can adopt modes such as translation, go up and down, turn over, rotate and slide, and this application embodiment does not do the restriction to this.

Illustratively, a sliding schematic view of a paddle provided according to some embodiments is illustrated in fig. 6. As shown in fig. 6, the shifting piece performs a translational motion in the left-right direction relative to the lens of the camera, and when the shifting piece slides to the front side of the lens of the camera, the lens of the camera can be completely shielded, so that privacy protection of the camera is realized.

Continuing to refer to fig. 6, the camera is further provided with a slide rail, the lens is located inside the slide rail, the shifting piece can perform horizontal movement on the slide rail in the left-right direction, and the shifting piece shields the lens of the camera by sliding on the slide rail.

In some embodiments, the pick-up of the camera and the slide rail of the camera may be provided with at least one contact, and the detection circuit determines the position of the pick-up relative to the lens by detecting whether the contact on the pick-up of the camera and the contact on the slide rail of the camera are in contact.

First, a detection circuit according to an embodiment of the present application will be described.

In an embodiment of the present application, the detection circuit may be connected to a processor of the display device, and the detection circuit is configured to send a position signal to the processor during the sliding of the paddle, the position signal being indicative of a position of the paddle relative to the lens.

Illustratively, a schematic diagram of a detection circuit provided according to some embodiments is illustrated in fig. 7. As shown in fig. 7, the detection circuit includes a first detection module and a second detection module, the first detection module may be disposed on the dial, and the second detection module may be disposed on the slide rail. The first detection module and the second detection module are both provided with at least one contact. The contact of the first detection module and the contact of the second detection module are contacted in the sliding process of the poking sheet, so that the detection circuits form different power-on loops in the contact process of different contacts.

The first detection module further comprises a third voltage dividing resistor R3 and a first capacitor C1. First ends of the third voltage-dividing resistor R3 and the first capacitor C1 are grounded, and second ends of the third voltage-dividing resistor R3 and the first capacitor C1 are connected with contacts of the first detection module. The third voltage dividing resistor R3 is used for limiting the current in the detection circuit, and the first capacitor C1 is used for stabilizing the voltage in the detection circuit and avoiding the voltage in the detection circuit from jumping.

It should be noted that, in the embodiment of the present application, the number of the contacts is not limited, as shown in fig. 7, in the detection circuit, the first detection module and the second detection module both include two contacts, the first detection module includes a first contact and a third contact, and the first detection module includes a second contact and a fourth contact.

The first contact is arranged at the edge of the first direction of the shifting sheet, and the second contact is arranged in the first direction of the sliding rail. The third contact sets up the edge at the second direction of plectrum, and the fourth contact setting is at the second direction of slide rail. Specifically, taking fig. 7 as an example, the first direction is the left side, and the second direction is the right side.

For example, when the lens is shielded by the pick, the contact of the first detection module is not in contact with the contact of the second detection module. At this time, the second detection module alone forms a first loop, which generates the first position signal, i.e., the zero-level signal Cover _ DET1 being 0.

Illustratively, when the shifting piece slides towards the first direction from the front of the lens, the first contact and the second contact are contacted, and the first detection module and the second detection module jointly form a second loop. Since the first detection module further includes the first power source IOVDD and the first voltage dividing resistor R1, the first contact is connected to the first power source IOVDD through the first voltage dividing resistor R1, and when the first contact and the second contact are contacted, the first power source IOVDD supplies power to the second loop to generate the second position signal. Wherein the value of the second position signal may be as shown in equation (1).

Illustratively, when the pull tab slides from the front of the lens to the second direction, the third contact and the fourth contact are contacted, and the first detection module and the second detection module together form a third loop. Since the first detection module further includes the second power supply DET-VDD and the second voltage dividing resistor R2, the third contact is connected to the second power supply DET-VDD through the second voltage dividing resistor R2, and when the third contact and the fourth contact are contacted, the second power supply DET-VDD supplies power to the third loop to generate the third position signal. Wherein the value of the third position signal may be as shown in equation (2).

It should be noted that, in this embodiment of the present application, the difference between the values of the second position signal and the third position signal may be realized by different power voltages, or may be realized by different voltage dividing resistors, which is not limited in this embodiment of the present application.

Illustratively shown in fig. 8 is a schematic diagram of another detection circuit provided in accordance with some embodiments. As shown in fig. 8, the first power supply and the second power supply both use the same IOVDD, and the first voltage dividing resistor and the second voltage dividing resistor sample different resistance values, so that the second position signal and the third position signal have different values.

By way of example, a schematic diagram of yet another detection circuit provided in accordance with some embodiments is illustrated in fig. 9. As shown in fig. 9, the first divider resistor and the second divider resistor sample the same resistor R1. The first power supply adopts IOVDD and the second power supply adopts the same DET-VDD, and the power supply voltages of the first power supply and the second power supply are different, so that the values of the second position signal and the third position signal are different.

Based on the detection circuit provided in the above embodiment, different control modes when the processor receives different position signals will be described below.

In the embodiment of the present application, the processor may determine that the lens of the camera is completely covered, i.e., state 1, when receiving the first position signal Cover _ DET 1. The processor, upon receiving the second position signal Cover _ DET2, may determine that the paddle is moving left and not fully occluding the lens, i.e., state 2. The processor, upon receiving the third position signal Cover _ DET3, may determine that the paddle is moving to the right and does not completely block the lens, i.e., state 3.

A control flow diagram providing privacy protection according to some embodiments is illustrated in fig. 10. For example, when the processor determines that the camera is in the state 1, it may first determine whether the camera application is open, and if the camera application is not open, control the camera to keep the closed state. And if the camera application is opened, prompting that the camera is not opened in an application interface on the display.

Illustratively, when the processor determines that the camera is switched from state 1 to state 2 or state 3, the processor enters a pre-boot state and starts to prepare for initializing the camera. If the camera stays in the state 2 or the state 3 continuously, the application state detection process is started, if the application is not started, the camera automatically enters the closing state, and if the application of the camera starts, the application end pops up to prompt that the camera is not completely opened/closed.

Illustratively, when the processor determines that the camera is transitioning from state 2 to state 3, the camera is turned on. If the application is opened, the camera normally outputs images, and if the application of the camera is not opened, the camera enters a sleep mode.

Illustratively, when the processor determines that the camera is transitioning from state 3 to state 2, the camera is turned on. If the application is opened, the camera normally outputs images, and if the application of the camera is not opened, the camera enters a sleep mode.

Illustratively, when the processor determines that the camera is converted from state 3 or state 2 to state 1, if the camera application is not opened, the camera is closed, and if the camera application is opened, the processor prompts that the camera is not opened.
