CONTROL SYSTEM FOR DISPLAY SCREEN, INPUT APPARATUS AND CONTROL METHOD
First Claim
1. A control method of a display screen, comprising:
- continuously capturing an image toward a first side faced by a display screen of a display apparatus through an image capturing unit; and
executing an image analyzing process for the image captured by the image capturing unit via a processing unit, wherein the image analyzing process comprises;
detecting whether an object has entered an initial sensing space, wherein the initial sensing space is located at the first side, and the initial sensing space is located within an image capturing range of the image capturing unit;
establishing a virtual operating plane according to a location of the object when the object enters the initial sensing space is detected, wherein a size of the virtual operating plane is proportioned to a size of the display screen; and
detecting a movement information of the object in the virtual operating plane for controlling contents of the display screen through the movement information.

Abstract
A control system for a display screen, an input apparatus and a control method are provided. An image capturing unit is used to continuously capture an image toward a first side of a display apparatus, and a processing unit is used to execute an image analyzing process for the captured image. The image analyzing process includes the following steps. Whether an object enters an initial sensing space located at the first side is detected. A virtual operating plane is established according to a location of the object when the object enters the initial sensing space is detected, wherein a size of the virtual operating plane is proportioned to a size of the display screen. A movement information of the object in the virtual operating plane is detected for controlling content of the display screen through the movement information.
