Abstract

See full text

For an image of an object for use in biometrics and the like, if the imaging object is still is detected with a simple configuration. From two pieces of image data that have been captured in time series, the absolute value of the difference in brightness of pixels in the identical position is calculated, and the number of pixels whose absolute values exceed the threshold value indicative of the limit of the brightness change is counted. The counted result is compared with the movement determination threshold value to determine if the imaging object is still.
