Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
72 words
A motion detecting apparatus having a light-receiving means for detecting a change of a displayed image and which are attached to an optional part of the display screen of an image display means; and a detecting means for outputting a detected signal in accordance with the change detected by the light-receiving means wherein a motion is detected by the change of the displayed image at an optional part of the display screen.
Claim 2
Dependent Claim
54 words
A motion detecting apparatus as claimed in claim 1, wherein a change of the displayed image which is detected by the detecting means is a change of, for example, a luminance, a density and a color (a hue, a brightness, a chromaticity) and a variety of change such as generation of a predetermined pattern.
Claim 3
Dependent Claim
159 words
A motion detecting apparatus comprising a receiving means for detecting a change of a displayed image by attaching on an optional part on the display screen of the image displaying means, a peak keeping means for keeping a peak value in accordance with a cyclical change according to a displaying method of the image displaying means based on the receiving result of the light-receiving means, a delaying means for outputting a delayed signal which is delayed at two differential time constant by receiving a kept result of the peak keeping means, a detecting means for outputting a detected signal when a difference between the delayed signals which is more than a predetermined level is generated, by comparing the two different time constant from the delaying means, wherein a motion which has a level more than a predetermined level, of the displayed image is detected by a change of the displayed image at an optional part in the display screen.
Claim 4
Independent Claim
59 words
A method of detecting motion, comprising the steps of: detecting a change of a displayed image at an optional part of the display screen of an image display means; and outputting a detected signal when a change is detected; wherein a motion is detected by the change of the displayed image at an optional part of the display screen.
