Description

TV camera controls

technical field

The present invention relates to the field of camera technology, and more specifically, to a control device for a TV camera.

Background technique

With the development and progress of science and technology, TV multimedia and smart TV have been developed rapidly and widely used.

The arrival of smart TV conforms to the trend of "high-definition", "networking" and "smart" TVs. The most important thing about smart TVs is that they must be equipped with a fully open platform. Only through a fully open platform can consumers be widely mobilized. Participating in the function customization of color TV can realize the "demand customization" and "color TV entertainment" of color TV. This is the only effective way to solve the intelligent development of color TV.

Smart TV will realize various application services such as network search, IP TV, video on demand, digital music, network news, network video phone, etc. These application services are inseparable from video equipment---camera. The current smart TV video equipment is mainly divided into two types: one is an external camera, which is attached to the outside of the TV casing, and the angle can be adjusted manually; the other is a built-in camera with a fixed viewing angle, but it has the advantage of being more portable than an external camera.

Some forward-looking new technologies on smart TVs, such as "gesture-based human-computer interaction", need to install a depth camera on the TV or computer screen, and the person sitting opposite the camera can use gestures instead of the remote control. These new technologies have put forward higher requirements for the automatic control of the camera, and the existing built-in fixed camera and external manually adjustable camera, the switch and the adjustment of the viewing angle all need to be manually performed by the user, which is very inconvenient for the user.

Therefore, there is a need for a control technology that can automatically control the switch of the camera and the adjustment of the angle of view, so that the user can control the switch of the camera and the adjustment of the angle of view by using a remote controller or other methods that do not need to manually adjust the camera entity in person.

It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Embodiment one

FIG. 1 shows a schematic structural diagram of a control device for a television camera according to Embodiment 1 of the present invention.

As shown in FIG. 1 , the TV camera control device 100 provided in this embodiment includes a control unit 110 , a lifting unit 120 and an interface unit 140 , wherein the lifting unit 120 includes a lifting motor 122 and a motor driver 124 .

The camera 200 is fixedly connected to the TV through the lifting unit 120. The lifting unit 120 is preferably arranged on the back of the TV, so that the camera 200 can be hidden on the back of the TV when not in use, so as to maintain the integrity and aesthetics of the TV. As the lifting unit 120 rises, it rises to the upper part of the TV set for the user to take pictures.

The control unit 110 and the interface unit 140 can be arranged outside the body of the TV, or embedded in the body of the TV, so as to receive the camera control signal through the TV, and control the camera 200 according to the camera control signal The switch and the lifting of the lifting unit 120. The interface unit 140 connects the TV and the control unit 110 , and transmits the camera control signal received through the TV to the control unit 110 . Wherein, the camera control signal is sent by a remote control of the TV or a button on a button panel of the TV body. The camera control signal transmitted to the control unit 110 by the TV set can be sent from the remote controller, or can be sent by the user directly through the buttons on the TV set; the camera can be started simultaneously with the start of the TV set and controlled to rise; When the TV is turned off, the camera is also turned off and its descent is controlled, or its switch and/or elevation can be controlled by another camera control button during the operation of the TV.
