Abstract
A video signal delay circuit comprises an input horizontal transfer register supplied serially with an input composite video signal, an input vertical transfer gate, a plurality of columns of vertical transfer registers, an output vertical transfer gate, an output horizontal transfer register, a horizontal transfer clock pulse generating circuit, a vertical transfer clock pulse generating circuit and a vertical transfer gate pulse generating circuit. The vertical transfer clock pulse generating circuit generates a vertical transfer clock pulse at a rate of once per one horizontal scanning period of the input composite video signal and additionally generates one or more vertical transfer clock pulses during a specific time period. Or, the horizontal transfer clock pulse generating circuit generates a horizontal transfer clock pulse having a selected phase or a selected number of horizontal transfer clock pulses.
