IMAGE CONVERSION METHOD AND DEVICE Russian patent published in 2002 - IPC

FIELD: biometry; conversion, production, processing, and analyzing electronic images of living biologic objects. SUBSTANCE: for identifying objects (primarily living ones) making slight practically invisible periodic vibrations, producing and analyzing images of such objects in the background of both motionless and moving objects sequential frames of object image are produced, frame-to-frame difference in images is found, and during image processing total difference of at least two chosen sequential image frames is accumulated; object image conversion device is made in the form of CMOS image sensor that has multicomponent photosensitive converter and means for frame-to-frame difference image processing and functions to accumulate total difference in image frames obtained by multicomponent photosensitive converter. EFFECT: enlarged functional capabilities. 7 cl, 4 dwg
