Abstract
A dot interpolation control system according to the invention includes a dot pattern memory storing character pattern data having a predetermined dot matrix format. Dot data of four adjacent dots is obtained from the dot pattern memory. X and Y off-set values of a position in an area surrounded by the four dots are stored using one of the dot data of four adjacent dots as a reference point. Dot interpolated value data in the area surrounded by the four dots is stored in an interpolating table ROM in accordance with all combination of ON- and OFF-states of the dot data of four adjacent dots. The dot data of four adjacent dots and the X and Y off-set values are supplied to the interpolating table ROM. A dot interpolated value at a coordinate point indicated by the off-set values is generated in correspondence with ON- and OFF-states of the four adjacent dots.
