METHOD AND DEVICE FOR IMAGE TRANSFORMATION

摘要

The invention relates to biometry and can be used for transforming, receiving, processing and analysing electronic images of living biological objects including the detection of people having terrorist intentions. The inventive method and device make it possible to detect the objects, (mainly living) which produce insignificant periodical oscillations thereby making it possible to receive and analyse the images of said objects on a background of stationary and moving objects. The aim is achieved by receiving successive exposures of the object's image and evaluating picture-to-picture differences and accumulating a sum of differences of at least two successive exposures during the processing thereof. The inventive device for transforming the image of an object is embodied on the base of one crystal in the form of complementary MOS memory of an image detector. Said detector comprises a photosensitive multielement transducer (1) and means for processing the images of the picture-to-picture difference which contain an exposure memory (2,3), a unit for evaluating the picture-to-picture difference (4), a picture-to-picture difference summator (5) and control registers (6). Said devices accumulate the sum of the exposure differences detected by the photosensitive multielement transducer. Means for processing the images of the picture-to-picture difference is connected to an output unit of processed signals.
