Problems solved by technology

[0004] However, if a fixed light source is set on the display 105, it may affect the appearance of the display 105
Some pointing devices use fixed objects I1, I2 displayed on the display to determine the relative position of the remote controller 101 and the display 105, but such objects I1, I2 may hinder the user from watching the content on the display 105, and if The content displayed on the display 105 is similar to the objects I1 and I2, which may cause misjudgment of the relative positions of the remote control 101 and the display 105

Abstract

The invention discloses a display control method used on a display. The method comprises: (a) capturing a to-be-compared image on a target position; (b) comparing the image content of the to-be-compared image with the image content of a reference image, to generate an image relation message; (c) according to the image relation message, determining a relative position of a target device and the display; and (d) according to the relative position, controlling the display to display images. The invention also discloses a relative position determining method, independently formed by steps (a), (b), and (c). The invention also discloses a system using the method. The method can determine relative positions of the target device and the display under the condition that the display does not include a fixed reference point, and controls the display according to the relative positions, and horizontal moving determining range of the target device is increased, and application of the display control system is improved.

Description

technical field [0001] The present invention relates to a relative position judging method, a display control method, and a system using these methods, and particularly relates to a relative position judging method on a display not including a fixed reference point, a display control method, and a system using these methods. Background technique [0002] figure 1 A schematic diagram of a pointing and positioning device in the prior art is shown. Such as figure 1 As shown, the pointing and positioning device 100 includes a remote controller 101 and a host 103 . The user can control the cursor Cr on the display 105 by moving the remote controller 101 . In order to correctly determine the relative position of the remote control 101 and the display 105 , the display 105 usually includes a fixed reference point for positioning the remote control 101 . For example, the reference point can be the light sources L1 and L2 disposed on the display 105 . [0003] The remote control...
