An apparatus is provided for processing the output signals of a charge transfer device having at least one row of photoelectric elements. The charge transfer device produces output signals with charge levels that are provided to a shift register having a plurality of elements. The successive charge levels from each photoelectric element are provided to respective shift register elements, and the charge levels are transferred within the shift register to a readout terminal. Some of the charge is retained by each element as the charge is transferred. The retained charge is added to the next charge transferred into the element. This adding of residual charges averages the charges transferred, producing undesirable noise. A sample and hold device removes sampling artifacts inherent in the signal provided by the CCD, to produce a signal representing successive image pixel values. A peaking filter emphasizes high frequency components relative to low frequency components, to compensate for low pass filtering effects which may occur in the CCD.

A noise suppression, signal recovery circuit for use with an array of charge coupled device having a plurality of phase readouts. The video information present in the multiple phases are combined into a single video output signal by using a minimal number of parts while providing for noise suppression designed to suppress typical noise present in charge coupled device arrays.
