ABSTRACT:
A display control apparatus in a system which is equipped with a plasma display unit as a standard I/O device and which can arbitrarily be connected to a monochromatic or color CRT display unit, includes a CRT palette in which gradation or color data is set from a CRT-BIOS, a PDP palette in which PDP gradation data is set, an arithmetic circuit for performing a predetermined arithmetic operation of the color data from the CRT palette and outputting gradation parameters, and a conversion table for storing a correspondence between the PDP gradation data and the CRT gradation data or the gradation parameters. The CRT gradation data set in the CRT palette is converted into PDP gradation data by the conversion table for storing the correspondence between the CRT gradation and the PDP gradation. The color data set in the CRT palette is subjected to a predetermined arithmetic operation by the arithmetic unit, thereby generating the gradation parameters. The parameters are converted into the gradation data by the conversion table for storing the correspondence between the CRT gradation parameters and the PDP gradation data. The converted data is set in the PDP palette.
