Cursor control method and device using the method

Abstract

The invention discloses a cursor control method used for controlling the movement of a cursor on an image display device. The method comprises the following steps: at least two reference points are provided to generate a preset spectrum, and the preset range is defined; an image sensor pointing to the circumference of the reference points and within the preset range is provided; the preset spectrum is received by using the image sensor to form a digital image; the imaging position and the shape of the reference points on the digital image are decided to generate a first parameter; the distance and angle compensation is performed to the first parameter; the pointing position of the image sensor is moved within the preset range to generate a second parameter; and the moving distance of the imaging position of the reference points on the digital image is calculated according to the compensated first parameter and the compensated second parameter to relatively control the movement of the cursor. The invention also provides a device using the cursor control method.

Description

technical field [0001] The invention relates to a cursor control method and a device using the method, in particular to a control method for controlling an interactive cursor displayed on an image display device and a device using the method. Background technique [0002] Existing index positioning devices and methods, such as Taiwan Patent No. 588258 "Using Photography to Carry Out Index Positioning Device", this patent uses a photographic index device to first do stroke processing on the display area image of the display screen, thereby obtaining The coordinate values ​​of the four corners of the display area in the image, and then through the coordinate calculation program to calculate the coordinate values ​​of the camera aiming point on the actual screen, instead of using the impact point signal or synchronization signal to obtain the coordinate value of the impact point of the traditional light gun. However, in actual use, although this method allows users to use the p...

Problems solved by technology

However, in actual use, when using the optical device to sense the image area, the imaging distance between the sensing array and the captured object and the rotation angle of the sensing array during imaging will all affect the position of the image obtained on the sensing array, If the correction is not performed at the same time, miscontrol will occur, and because the image detected by the optical device contains other objects, it is also more complicated in image recognition
