The purpose of the invention is the expansion of functionality due to the formation of a sliding histogram is achieved by using shift registers made in the form of photodetector lines on a CCD, the illumination of which is carried out by the light signals of the generator, the inputs of which are connected to the outputs of the decoder of the signals under study. 3 il.

Description

one

The invention relates to the field of computing instrumentation and can be used in the analysis and processing of information, in particular in the processing of video signals of the image.

The aim of the invention is to enhance the functionality by forming a sliding histogram.

Figure 1 shows the structural diagram of the device; Figures 2 and 3 illustrate embodiments of a light signal generator.

The device contains a matrix consisting of N shift registers 1, ..., 1Ы, made in the form of photodetector lines on devices with charge coupling, a generator of 2 clock pulses, the output of which is connected to the synchronization inputs of lines 1, .. ,, 1N , decoded 3, the outputs of which are connected to the corresponding inputs

a generator of 4 light signals, the outputs of the latter are optically coupled, for example, using fiber optic bundles 5, ..., 5n to the optical inputs of all photodetectors of the corresponding line 14,. . . , 1 N The generator can be executed, for example, in the form of N isolated point sources 6 ,, ..., 6N of light (figure 2) or one source of light 7 and controlled optical transparencies 8,.,., 8N

(fig.Z).

The device works as follows.

The input n-bit code, where n log N, of the signal under study is fed to the input of the decoder 3, in which it is converted into the corresponding number code, as a result of which an (, ..., N) output appears an electrical signal. Under the action of this signal, the i-th point source 6 is illuminated; or discovered

In each photodetector of this line, under the action of light, a corresponding charge packet is formed, which, moving along the shift register, is added to a new charge packet from a new light pulse in the case of a signal appearing at the corresponding output of the decoder 3, and so on. accumulation of the formula of the invention occurs
