Abstract
A display control apparatus comprises area specifier, area determiner and signal selector. The area specifier specifies at least one area of a bit map memory. The area determiner determines whether the scan position on the bit map memory is in the specified area or not, and, according to the determination, controls the signal selector so as to send the output of the bit map memory directly or through a look-up table to a display unit. In a modification, the signal selector selects the signal to be sent to the display unit from among the outputs of different look-up tables.
