Video printer device

Abstract

Abstract PURPOSE:To recognize a video which an user wants to print out on a television screen or a monitor one without directly printing out by reproducing a digital gradation density signal stored in a video memory on the television screen or a different monitor screen. CONSTITUTION:A color decoder part 3 splits an input color video signal into signals R, G and B at the time of said input color video signal. With an output from a voltage controlled oscillator VCO 12 as a sampling clock, an A/D conversion part 4 converts the signal into a digital gradation density signal, and a memory part 5 sequentially stores the output signal of the A/D conversion part 4 in the memory with the aid of a control signal inputted from a memory control part 13. In a mode reading data out of a memory part 5, data is read out at a clock with frequency the same as the timing at the time of storage, returned to an analog signal by a D/A conversion part 6 and encoded by a color encoder part 7, thereby obtaining a reproduction video signal. Provided that the timings and phases of composite synchronizing signals applied when the reproduction video signal is encoded are completely made equal to the phase and timing when the digital gradation density signal is read out of the memory part 5.
