Abstract
Abstract A computer system replaces an input device, such as a mouse, with a video camera having an image recognizing function and an image extracting function to detect motions of the operator's body directly, and controls a computer apparatus to move a cursor and check on an icon on the basis of the output signals of the video camera. The computer system controls the computer apparatus also on the basis of a signal provided by the video camera upon the detection of light emitted by a particular object. The computer system is capable of making the computer apparatus understand an operator's intention without using any conventional input device, such as a mouse, and of facilitating an operator's input operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A computer system for carrying out control operations according to operator's actions, said computer system comprising: an imaging device for picking up an image of a subject and generating an image signal representing the image of the subject; an image extracting circuit for extracting a plurality of areas meeting given conditions from the image represented by the image signal provided by the imaging device, and providing position data representing the positions of the extracted areas; a position examining means for determining whether or not the positions of the extracted areas represented by the position data are within a plurality of predetermined detection areas, respectively; and a computer apparatus for carrying out a plurality of control operations specified by the detection areas on the basis of a plurality of results of the determinations corresponding to each predetermined detection area made by the position examining means.
Claim 2
Dependent Claim
144 words
A computer system for carrying out control operations according to operator's actions, said computer system comprising: an imaging device for picking up an image of a subject and generating an image signal representing the image of the subject; an image extracting circuit for extracting a plurality of areas meeting given conditions from the image represented by the image signal provided by the imaging device, and providing position data representing the positions of the extracted areas; a position examining means for determining whether or not the positions of the extracted areas represented by the position data are within a plurality of predetermined detection areas, respectively; and a computer apparatus for carrying out a plurality of control operations specified by the detection areas on the basis of a plurality of results of the determinations corresponding to each predetermined detection area made by the position examining means.
Claim 3
Dependent Claim
71 words
A computer system according to claim 1, further comprising a display for displaying images represented by input signals given thereto, wherein the computer apparatus supplies a signal representing a character to the display to instruct the display to display an image of the character, and controls the display according to results of examination made by the position examining means to move a plurality of portions of a image of the character.
Claim 4
Dependent Claim
108 words
A video camera comprising: an imaging device for picking up an image of a subject and generating an image signal representing the image of the subject; an image extracting circuit for extracting a plurality of areas meeting given conditions from the image signal provided by the imaging device, and providing position data representing positions of extracted areas; a position examining means for determining whether or not the positions of the extracted areas represented by the position data are within a plurality of predetermined areas, respectively; and a communication means for sending out operation signals indicating each determination corresponding to each predetermined area made by the position examining means.
Claim 5
Dependent Claim
