ABSTRACT:
According to the prior art, the image data expanded in the image memory is read out for display of an expanded picture image so that not only an additional memory capacity has been required for the expanded display but also it takes a considerable time to expand. According to the invention, there is provided a control device for output a horizontal synchronizing signal once in a number of cycles. In response to this modified horizontal synchronizing signal, image data is read out of the image memory and allotted to a number of pixel positions for expanded display.
