IMAGE DISPLAY SYSTEM
First Claim
1. An image display system comprising:
- an image display device, comprising an image generation unit which generates an image including a predetermined image, and an image display unit which displays this generated image; and
a remote control device, which comprises an actuation unit for controlling display by said image display device, and which transmits details of actuation performed upon said actuation unit to said image display device;
wherein said remote control device comprises a camera which, when said remote control device is pointed towards said image display device, can capture an image displayed upon said image display unit, and;
said image generation unit of said image display device creates an image to be displayed by said image display unit, based upon the display state of said displayed image which has been captured by said camera.

Abstract
This image display system includes an image display device, including an image generation unit which generates an image including a predetermined image and an image display unit which displays this generated image, and a remote control device, which includes an actuation unit for controlling display by the image display device. The remote control device includes a camera which, when the remote control device is pointed towards the image display device, can capture an image displayed upon the image display unit; and the image generation unit of the image display device compares together the coordinates of the predetermined displayed image displayed upon the image display unit, and the coordinates of the captured image of the predetermined image within the image captured by the camera, and thereby detects a remote pointing position at which the remote control device is pointing. And the image generation unit generates a displayed cursor image to be displayed at the remote pointing position, and displays it upon the image display unit.

17. An image display system, comprising:
-
an image display device, comprising an image generation unit which generates an image including a predetermined image, and an image display unit which displays this generated image; a remote control device, which comprises an actuation unit for controlling display by said image display device, and which transmits details of actuation performed upon said actuation unit to said image display device; and a first camera which captures an image of a scene in front of said image display unit; and wherein said remote control device comprises; a second camera which, when said remote control device is pointed towards said image display device, can capture an image displayed upon said image display unit; a position detection unit which compares together the coordinates of a predetermined display image which is being displayed upon said image display unit, which have been acquired from said image display device, and the coordinates of the captured image of said predetermined image within the image captured by said second camera, and thereby detects the orientation of said remote control device with respect to said image display unit, and the relative position of said remote control device, which specifies the distance between said image display unit and said remote control device; and a transmission unit which transmits said orientation and said relative position of said remote control device, detected by said position detection unit, to said image display device; and said first camera comprises a camera control unit which controls the image capture direction of said first camera, based upon the orientation and the relative position of said remote control device which have been transmitted from said transmission unit. - View Dependent Claims (18, 19, 20, 21)
