Embodiment Construction

[0019] The principle of the present invention is described below. First, use the function keys on the remote control device to send a control signal to the TV, so that the TV enters the TV interactive operation state. In addition to displaying the interactive menu screen on the screen, the TV also automatically displays a special marker on the screen. Secondly, the menu screen is captured by the image acquisition device installed on the remote control device to detect markers, and the location of the remote control device is obtained by calculating the position of the markers, that is, the specific part of the screen that should be selected. Finally, a corresponding indicator cursor is displayed at the calculated screen position to feed back to the operator. The operator can change the selected position or perform a selection operation with reference to the indicating cursor.

[0020] Embodiments of the present invention are described below with reference to the drawings.

Abstract

This invention provides, a remote control device based on a video image detection including an image collection device collecting video images and converting them into video signals, a selection position computing device for detecting markers in the said signals and computing the optical marker position directed by the said remote control device, an order input device for inputting orders entering or exitting the menu item selection state to the said device and an signal transmitting device for receiving the optical position information output by the said selection position computing device and transmitting the control signals instructing the said optical marker position information to make the display devices to display the target directed by the device. It also includes a system and method applying remote control devices.

Description

technical field [0001] The present invention relates to a remote control device based on image detection and its method, in particular, to a remote control device that determines the direction of the remote control device by detecting markers in an interactive TV, thereby selecting candidate objects, and performing remote control operations Apparatus and methods. Background technique [0002] A common TV remote control selects TV channels and different functions by pressing the number and function keys provided on the remote control. However, these remote controls do not have an interactive selection function. With the continuous expansion of TV functions, the analog TV with simple viewing function is developing into interactive and intelligent digital TV. In the digital TV picture, in addition to displaying video, a menu interface can also be provided to realize various data broadcasting, multimedia services and video on demand (VOD) services, etc. Convenient and simple ...
