1. A method of displaying an image formed by video data on a screen and viewed by an operator, said method comprising:
- a displaying step of sequentially displaying the video data on the screen;
an image inputting step of inputting facial image information indicative of information of a face of the operator;
an image processing step of detecting opening and closing of eyelids of the operator based on the image information of the face;
a signal generating step of generating a rewrite signal indicative of rewriting the video data displayed on the screen; and
a display controlling step of performing a principal change of the video data displayed on the screen when the rewrite signal is generated in said signal generating step and when the operator fails to look at the screen on the basis of the eyelid opening/closing state obtained by said image processing step.

Abstract
A display section displays an image to be displayed on a screen. An image processing section detects an opening/closing of an operator'"'"'s eyelids on the basis of an image of the operator'"'"'s face. A display controlling section changes the video data displayed on the display screen through a display section on the basis of the eyelid opening/closing state detected by the image processing section in accordance with a timing at which the operator does not look at the display screen.

15. An apparatus, run by an operator, for displaying an image formed by video data, said apparatus comprising:
-
displaying means, including a screen, for sequentially displaying video data on the screen; imaging means for imaging at least a face of the operator to generate facial image information; image processing means for detecting opening and closing of eyelids of the operator based on the facial image information; signal generating means for generating a rewrite signal which indicates rewriting of the video data displayed on the screen; and display controlling means for performing a principal change of the video data displayed on the screen by said displaying means when the rewrite signal is generated by said signal generating means and when the operator fails to look at the screen on the basis of the eyelid opening/closing state obtained by said image processing means. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method of displaying an image formed by video data on a screen and viewed by an operator, said method comprising:
-
a displaying step of sequentially displaying the video data on the screen; an image inputting step of inputting facial image information of a face of the operator; an image processing step of detecting opening and closing of eyelids of the operator based on the image information of the face, said image processing step having, an edge extracting step of generating a facial edge image by extracting edges of the facial image information, said edge extracting step obtaining the facial edge image by effecting a spatial differential process on the facial image information; and a display controlling step of performing a principal change of the video data displayed on the screen when the operator fails to look at the screen on the basis of the eyelid opening/closing state obtained by said image processing step. - View Dependent Claims (30)
