ABSTRACT:
In a coordinate converter in which more than one input address corresponds to one output address (related to a specific location on a display screen) and in which input addresses can occur in either of two sequences, an apparatus is disclosed for changing the output addresses by a preselected amount only when the input addresses are received in one of the sequences. In the absence of apparatus for changing the output addresses, the image on the display screen shifts depending on the sequence in which the input addresses occur.
