The invention relates to applied television. ,

The purpose of the invention is the expansion of functional capabilities by the Formation of the brightness distribution function of the image.

The drawing shows a structural-electrical diagram of a television camera.

The television camera contains a CCD array 1 with accumulation section 2, memory section 3 and output register 4, synchronizer 5, amplifier 6 for controlling impulses 15 for accumulation section and memory, amplifier for generating 7 pulses for controlling the output register, Shaper 8 for constant voltage levels, divider 9 frequency, block 20 10 switching, the generator 11 of a linearly varying voltage and the recording unit 12.

The television camera works as follows. 25

The image is projected onto the accumulation section 2 and the well-known mode of forming the video signal of the image is carried out;

In the Signal shaping mode of the function of the distribution of the magnitude of the charge packets in the CCD cells, the device operates as follows. Frame quenching pulses from the output of the synchronizing generator 5 are fed to the input of the frequency divider 9, the output of which forms a voltage pulse that arrives at the switching unit 10 and the generator 11 of linearly varying voltage. With the passage of personnel extinguishing impulse from the frequency divider 9 into the switching unit 10, the phase buses, accumulation sections 2 are disconnected from the output of the amplifier-driver 6 control pulses and connected to the generator 11 of linearly varying voltage, which starts simultaneously with the switching of phase accumulation section 2. Moreover, a potential equal to the potential of the substrate, i.e., is supplied to the Phase tires under the electrodes of which the charge packets are not formed. under the electrodes of this phase there are no potential holes. The generator 11 of a linearly varying voltage forms a linearly ³ decreasing voltage on this Phase bus, the magnitude of which by the time of the end of the block damping pulse must be

such that the potential holes in the accumulation section disappear.

Upon completion of the Formation of static characteristics, the television camera again generates the video signal of the image until a signal appears at the output of the frequency divider 9.
