Abstract

PURPOSE: To secure reproduction for the double-screen color picture via one unit of the A/D converter by supplying the luminance signal of the slave screen plus the two color difference signals to the A/D converter and then giving synchronization again to the three signals changed into the time series to secure the compounding with the master screen signal.
CONSTITUTION: The luminance signal, red signal and blue signal of the slave screen are supplied to terminals 106∼108 of switch 37 at color compounding part 30' from slave channel part 20, and these signals are supplied to A/D converter 31 in the fixed sequence via switch 37. At the same time, the luminance signal and color difference signal are written into main memories 331 and 332 via buffer memories 321 and 322, and the luminance signal of memory 331 is supplied to video projection part 16' via switch circuit 35 between D/A converter 34 and master channel part 10. And the color difference signal of memory 332 is supplied to video projection part 16' via the permutation unit comprising shift register 38 plus switches 391 and 392, D/A converter 34 and switch circuit 35. Thus the bouble-screen is obtained.
