Abstract: A device for selective search of objects using images thereof, comprising a number of units connected in series, viz.: a TV-camera producing video signals of the object's image, including a scanner and a synchronizer and determining the current values of geometric parameters of the object's image; an amplitude selector whose video signal clipping level is adjusted according to the preset level of the brightness and chromaticity of the object's image; a servomechanism controlling displacements of said objects relative to the TV-camera; and an initiating pulse oscillator connected to said servomechanism. According to the invention, the device is provided with a logical unit connected in series between the amplitude selector and the servomechanism and coupled to said initiating pulse oscillator, and with a TV-camera raster reference line sensor connected to said logical unit. The logical unit serves to preset the reference values of geometric parameters of the object's image, to measure the current values of geometric parameters of the object's image at a preset brightness and chromaticity levels and to compare them with the reference values. The purpose of the reference line sensor is to pick out any one of the TV-camera raster lines to be used as a reference line for said measurements of the current values of geometric parameters of the object's image at the moment when they cross the raster line in the course of mutual displacements of the object and the TV-camera.
