Problems solved by technology

[0008] Since the existing remote control or mouse cannot have the functions of the other party at the same time, when watching digital TV, the user must use the remote control to select the channel and use the mouse to click on the program to watch, thus causing the user to operate the remote control at the same time Use the controller and the mouse to select channels, click on programs or select menus, which will easily cause disadvantages such as reduced use value and inconvenient operation.

Abstract

A photographic type pointer positioning control device (200)for controlling the positioning of a pointer on a display (100)screen by means of photographing the display screen (100)with a video camera (230)and then processing the video signal thus obtained through an image out-line and recognition processing process and then computing the processed data through a computing unit into (240)a coordinate value corresponding to the aimed point of the video camera (230)at the display screen (100).

Description

technical field [0001] The present invention relates to a device for cursor positioning by means of photographing, especially a photographic cursor device which uses an image synthesis circuit to synthesize a special mark or cursor into the display area of ​​the screen for display, and draws the image signal captured by the camera as a stroke And identification processing, to obtain the coordinate data of special marks or cursors and camera aiming points or center points, and then output the image signals after image synthesis processing through the image synthesis circuit to the display area of ​​the screen for display, and display the coordinates of special marks or cursors The value is transmitted to the information system to replace the traditional mouse (including optical mouse) and remote control, and allows the user to use the photographic cursor device to control any type of screen without being limited by the type of screen. Background technique [0002] In recent y...
