Claim 14:
15. An image sleep analysis system, comprising:
a visible-light sensor outputting a plurality of visible-light images of a body;
a processing unit electrically connected to the visible-light sensor to perform following steps of:
(a) obtaining the visible-light images during sleep duration;
(b) comparing the visible-light images to determine a plurality of image differences among the visible-light images and determining a first image position of each of the image differences;
(c) identifying a plurality of features of each of the visible-light images and determining a second image position of each of the features;
(d) determining a motion intensity of each of the features according to the first image positions of the image differences and the second image positions of the features; and
(e) monitoring a variation of motion intensities of the features, and analyzing the variation of motion intensities of the features to generate a sleep quality report;
a first communication module electrically connected to the processing unit; and
a display device linking to the first communication module to obtain the sleep quality report and displaying the sleep quality report.
