An image display control signal is developed from a plurality of bit-plane memories having digital image data stored therein, by applying bits corresponding to the same location that are simultaneously read out from the plurality of bit-plane memories to a control input of a respective one of a corresponding plurality of switches. A digital signal representative of a display characteristic (such as intensity) for each of the bit-plane images is applied to a D/A converter for generating an analog display characteristic signal. The analog display characteristic signal for each bit-plane is applied to the signal input of a respective one of the switches. The signal output of each switch is coupled to a processing circuit which processes the analog display characteristic signals for developing the image display control signal. In a preferred embodiment, the processing comprises selecting the analog display characteristic signal corresponding to the greatest image intensity as the image display control signal. |
