ABSTRACT:
An image display apparatus for displaying an image and characters superposed on the image comprising a synchronizing signal dividing unit for dividing the frequency of an input synchronizing signal to generate a divided synchronizing signal, a character generating unit for generating, in response to the divided synchronizing signal, characters to be superposed on the image, and a character speed converting unit for converting the speed of the characters generated by the character generating unit, thereby the number of characters outputted from the character speed converting means in one synchronization period is made to be substantially constant regardless of the frequency of the input synchronizing signal.
