Camera

This creation is about a camera device, especially a camera device with privacy protection.

With the popularity of smart phones and tablets, there may be photography devices everywhere in everyone's living space, and because of the development of network communication technologies and the rise of social software, video cameras are used for video communication, or Webcasting has become a popular communication and information dissemination method. In addition, the development of technology for transmitting images over the Internet has enhanced the networking capabilities of cameras, and traditional surveillance cameras have gradually combined with cloud technologies. Therefore, people's living space and life schedule can be photographed by the camera at any time, and then distributed through the Internet. Moreover, in recent years, there have been many incidents in which malicious images are implanted, or hackers maliciously invade, causing the leakage of private images, which has caused people's doubts about the privacy of the camera device.

However, image monitoring is a long-lasting behavioral pattern, but it often conflicts with personal privacy. Users sometimes don't want to be monitored. Turning off the monitor is of course the most direct method, but often forgets after power failure. Electricity makes it impossible to obtain data when demanding image data, and since the camera is designed to be hidden as much as possible, the user is not sure whether the camera has actually been powered off.

Therefore, a large number of camera devices on the market currently have the function of privacy protection. Most of the privacy protection measures of the existing camera devices adopt a software control mode for the user to control the camera device to stop shooting when it is not desired to be photographed. However, the use of software control may still be due to incomplete program execution or malicious software. As well as the hacking attack, it is invalid, because as long as the power is not cut off, others may launch the camera through the remote end of the network to spy on the privacy of others, so the effect of protecting the privacy of the user cannot be fully and effectively achieved. In addition, the user cannot intuitively discern whether the camera is continuously shooting the image, so that the operator cannot really feel at ease, and thus the protection of the user's privacy by such a commercial product is still not complete enough.

In addition, some existing camera devices use a physical shielding device (such as a shutter, a cover, etc.) as a technical means of privacy protection, which can be shielded from the outside of the lens of the camera module to force the camera to stop. Shoot an image. However, the shielding device used in the prior art camera device must drive the shielding device to be turned on or off by a motor or other mechanism, thereby causing the camera device to have a complicated structure and an increased volume due to the addition of the shielding device and the motor driving mechanism. And the disadvantage of increased cost arises.

Light state or opaque state.

The principle of the present application is to set the shielding device 20 on the light guiding path of the light entering the lens 11 of the camera module and the photosensitive element 13. When the shielding device 20 is permeable, the light can be projected and imaged through the lens 11 In the component 13, the camera module 10 can perform the image capturing operation normally, and when the operator wants to stop the camera module 10 from capturing the image, the shielding device 20 can be controlled to be opaque to ensure The camera module 10 cannot continue to capture images, thereby achieving the effect of privacy occlusion.

The control and processing unit 30 is electrically connected to the camera module 10 and the driving circuit 21 for controlling the control of the camera module 10 and the driving circuit 21 and the signal processing hub. The control and processing unit 30 can output a control signal to the driving circuit 21, and then control the shielding device 20 to selectively form a light transmissive state or a non-transmissive state through the driving circuit 21.

As shown in FIG. 1 , the control and processing unit 30 can be connected to a switch unit 31 , and the user can input a control signal to the control and processing unit 30 through the switch unit 31 to control the camera module 10 to start or Closing, and controlling the screening device 20 selectively forms a light transmissive state or a non-transmissive state.

The switch unit 31 can adopt various types of switch devices. For example, the switch unit 31 can be a conventional push button switch or a toggle switch for the user to manually control the shielding device 20; for example, the switch unit 31 can The touch switch is used to enable the operator to control the operation of the shielding device 20 by using a touch control method. For example, the switch unit 31 can be a different form of a sound control switch or a photoelectric sensor switch. The switch allows the operator to control the operation of the shielding device 20 through voice control or photoelectric sensing. In addition, it is also possible to use a motion sensor as the switching device of the switch unit 31. When the switch unit 31 is a motion sensor, the operator can enable the control and processing unit 30 to receive a control signal to be turned on or off through a special gesture operation mode. The camera module 10, in turn, controls the screening device 20 to selectively form a light transmissive state or a non-transmissive state. In addition, the switch unit 31 can also be controlled by using biometrics (such as fingerprint recognition, face recognition, iris recognition, etc.).

In addition to the switch unit 31, the control and processing unit 30 can further connect a wireless receiving unit 32 and a connecting unit 33 for connecting to the network 40. The wireless receiving unit 32 and the control and processing unit 30 are electrically connected to receive a control signal from a wireless transmitting device, and then the control and processing unit 30 controls the shielding device 20 to selectively form a transparent light.

Therefore, the control and processing unit 30 of the present invention can cooperate with the infrared emitting device 35 or the radio frequency transmitting device 34 through the wireless receiving unit 32 to control the action of the shielding device 20. Alternatively, it can cooperate with an Internet of Things device operating with a radio frequency signal to control the operation of the shielding device 20.

The control and processing unit 30 can also be connected to a network 40 through the connection unit 33, and receive a control signal through the connection unit 33 and the network 40, thereby controlling the shielding device 20 to selectively Forming a permeable or opaque state. It should be noted that the connection unit 33 and the network 40 may be connected by a wired area network, a wireless area network, or a wireless mobile network.

The shielding device 20 is attached to the inner and/or outer side of the transparent cover 15, so that when the shielding device 20 becomes opaque, the transparent cover 15 becomes opaque, and the camera module is made 10 Cannot continue shooting images.

For example, in the embodiment shown in FIG. 7 , the camera module 10 is disposed in a protective casing 16 , and the protective casing 16 has an imaging window 17 , and the lens 11 of the camera module 10 is aligned with the imaging window 17 to enable imaging. The module 10 is capable of capturing an external image through the imaging window 17. The shielding device 20 of the embodiment is disposed at the imaging window 17 of the protective casing 16, so that when the shielding device 20 becomes opaque, the imaging window 17 becomes opaque, and the camera module 10 cannot continue. Shoot an image.

In the embodiment shown in FIGS. 8 and 9, the material layers of the shielding device 20 are directly formed on the outer surface of the lens 12 of the lens 11 of the camera module 10 by a deposition or coating process. As shown in FIG. 9, in this embodiment, the shielding device 20 has one or two transparent protective layers 201a, one or two transparent conductive layers 203a, and at least one liquid crystal material layer 202a.
