Abstract
An image control unit, for generating control signals corresponding to text or graphic characters, in cooperation with a video display device having an image point storage device, produces plural signals including signals for controlling horizontal and vertical synchronization, for loading of the image point storage device, and for indicating reference marks on the screen of the video display unit. The image control unit contains a programmable memory for storing control words associated with lines to be represented on the video display unit in a plurality of blocks. A plurality of lines of each block are stored as one line in the memory and each line is read out repeatedly, in accordance with the line length of its associated block. The line length of each block is set by control signals stored in the ROM for the preceeding block.
