ABSTRACT:
A display apparatus enables analog clock display with, for example, twelve numbers 1 to 12 and a pair of long and short hands. In the display apparatus, a control circuit produces instruction data for controlling an on-screen display circuit which generates color signals for displaying an analog clock image. The instruction data causes the on-screen display circuit to change the colors of the two numbers to which the long and short hands point in the analog clock image so that these two numbers are displayed in a different color from those of other ten numbers.
