Image displaying apparatus
First Claim
1. An image display apparatus, comprising:
- means for generating a video image with multiple regions;
means for varying the intensity of a selected region of the video image, created by the means for generating, about an intensity level for the selected region;
means for detecting by optical sensor the intensity of the selected region of the video image;
means for comparing the detected intensity of the selected region with an average of the detected intensity, the average corresponding to the level for the selected region, to derive variations in the intensity created by the means for varying;
means for identifying the selected region using the derived variations; and
means for changing the generated video image responsive to the identification of the selected region.

Abstract
A system and method for detecting when an operator selects one of multiple objects from a projected image. Image data, object data and relative position data drive a liquid crystal unit to form on a screen a composite display of both image and objects. When the operator presses a switch, a signal including the state of brightness from an optical sensor is entered into a brightness determinator of a personal computer. The brightness determinator initiates the determination of the brightness and then the object controller varies the brightness of each object. Along with the change in the brightness of objects, the brightness determinator decides the object indicated based on the brightness detected by the optical sensor to cause an object correspondence processor to effect the processing (conversion of a display) corresponding to the object selected by the operator.

6. A method for controlling the display of an image, comprising the steps of:
-
generating a video image with multiple regions; varying the intensity of a selected region of the video image about a level for the selected region; selecting a region of the video image; detecting by optical sensor the intensity of the selected region of the video image; comparing the detected intensity of the selected region with an average of the detected intensity, the average corresponding to the level for the selected region, to derive the created variations in the intensity; identifying the selected region using the derived variations; and changing the generated video image responsive to the identification of the selected region. - View Dependent Claims (7, 8, 9, 10)
