Signal generating system comprising a storage cartridge (1), manual control (2), a data handling microprocessor (3), a main generator (4) for generating a synthesized picture and producing color signals R, V, B in the form of quantized values and producing synchronizing signals S together defining a main picture. Added to the main generator (4) is an additional generator (6) which is synchronized by S and produces the signals R.sub.1, V.sub.1, B.sub.1 which form an additional background picture in synchronism with the main picture. Portions of the main picture are replaced by complementary portions of the additional image by means of a selection device (19) when the portions of the main picture have a color which is identical to the color stored in a register (7).
