Abstract
A flag memory is provided which stores a flag indicating whether or not a corresponding pixel is in the initial state. When writing has been performed on an image memory by a drawing unit, a value of the flag of a corresponding pixel is changed from a first value indicating that the pixel is in the initial state to a second value indicating that the pixel is not in the initial state. When a display unit reads a pixel value from the image memory, a flag corresponding to the pixel is read from the flag memory, and if the flag still has the first value, an initial pixel value is supplied to the display unit, and otherwise, a pixel value read from the image memory is supplied to the display unit.
