ABSTRACT:
An image size converter includes X1 through X4 value generators for respectively generating X1 through X4 values of an image size, first through fourth adders each of which receives a corresponding one of the X1 through X4 values from the X1 through X4 generators at one input thereof, a register for storing at least a decimal part of the said fourth adder and supplying the decimal part to the other input of each of said first through fourth adders, first through third exclusive ORs for detecting noncoincidence between at least the least significant bits of the integer parts of the sums from the second through fourth adders and of the first through third adders, and a size conversion data generator for receiving an image size conversion object dot pattern input in units of 4 bits and determining correspondence between the 4-bit input dot pattern and the first through 4-bit output dot patterns on the basis of the least significant bit of the integer part of the sum of the first adder, and a detection result of said the first through third exclusive ORs.
