The receptive mode of the detectors field is considered in the work. It is shown that this mode of application of the detectors fields is provided due to the two-zone structure of the elements of the detectors field and the use of the drift mechanism in the process of generating the output video signal and, most importantly, a separate analysis of the reactions of the central and peripheral regions of the detectors. Several different detectors configurations are proposed with an additional partition of the peripheral region into additional zones. The location of the object in the image and the linear dimensions of the object were determined by analyzing the relative position of the object and the elements of the detectors field with fixing the moments of the beginning and end of the intersection of the object and detectors areas. An algorithm for searching for objects in the image is developed.

Taking into account the features of the structure and functioning of the human visual system is one of the necessary stages in the creation of iconic systems.

The article substantiates and describes the operation of the detectors field in the mode of the receptive field. It is based on the mechanism of formation of receptive fields by on-off centers of the retina. The receptive mode of operation of the detectors field was achieved by separating the reactions of the central and peripheral regions of the detectors, which, like the on-off centers, have a two-zone structure and using the drift mechanism. The analysis of all possible cases of the mutual arrangement of the elementary field detector and the image of the object is carried out. Analytical expressions are obtained for the reactions of the central and peripheral regions for the simplest case of an object of constant brightness against a uniform background. Such a construction of the detector field made it possible, with a known drift velocity vector, to determine the location of the object and its linear dimensions. It is also shown that the accuracy of determining the location of an object increases when the peripheral region is divided into additional zones. A special form of cross-detector has been introduced. An algorithm for the operation of the detectors field in the receptive mode is developed and an example of its operation in real images is given.
