Apparatus for sensing location of object on screen
First Claim
1. An apparatus for sensing the location of an object on a screen, comprising:
- a remote input device having a transmitter for detecting a video signal at a position pointed by an optical system on the screen, transmitting the video signal as an infrared signal, and transmitting key data as an RF signal; and
a main body having a receiver for receiving the infrared signal and the RF signal from the transmitter and detecting the position pointed by the optical system on the screen by comparing the reception timing of the infrared signal with the output timing of the present video signal output to the screen.

Abstract
There is provided an apparatus for sensing the location of an object on a screen. The object location sensing apparatus includes an input device and a main body. A transmitter is installed in the input device, for detecting a video signal at a position pointed by an optical system on the screen, transmitting the video signal as an infrared signal, and transmitting key data as an RF signal. A receiver is provided to the main body, for receiving the infrared signal and the RF signal from the transmitter and detecting the position pointed by the optical system on the screen by comparing the reception timing of the infrared signal with the output timing of the present video signal output to the screen.

8. An apparatus for sensing the location of an object on a screen, comprising:
-
a remote gun-shaped input device having a transmitter that includes a video signal detected portion for detecting a video signal at a position pointed by an optical system on the screen and transmitting the video signal as an infrared signal, and a key input signal transmission portion for transmitting key data as an RF signal; and
a game device body having a receiver that includes a video signal detected timing calculation portion for receiving the infrared signal from the transmitter and the present video signal output to the screen and calculating the time from the output time of the frame of the video signal detected in the video signal detection portion to the detected time of the video signal by comparing the generated timing of the infrared signal with the output timing of the present video signal output to the screen, and a video signal detected position calculation portion for detecting the position pointed by the optical system on the screen on the time calculated by the video signal detected timing calculation portion, and outputting the detected timing information and key data information included in the RF signal received from the transmitter to an external device. - View Dependent Claims (9, 10, 11, 13, 14, 15, 16, 17)

12. A method of sensing the location of an object on a video screen using a computer-aided shooting game device, the shooting game device having a transmitter with a sensor, and a receiver, the method comprising the steps of:
-
detecting a portion of a first video signal at a position on the video screen at which the sensor is directed;
transmitting the portion of the first video signal from the transmitter to the receiver;
receiving the portion of the first video signal at the receiver;
receiving a second video signal displayed on the video screen at the receiver;
comparing the timing of the portion of the first video signal to the timing of the second video signal to determine a calculated time; and
determining the position on the video screen of the portion of the first video signal based on the calculated time.
