An absolute encoder comprising a first memory operable to store a first absolute value signal produced every constant time period, the absolute value signal representing an absolute value position. A second memory stores a second absolute value signal produced in a previous time period. A comparing/calculating section compares the first absolute value and the second absolute value and produce a difference amount. A dividing process section divides the difference amount in an equal rate within a producing time period of said first absolute value signal. An interpolated absolute value signal producing section reads the second absolute value signal and adds the difference amount in a stepwise manner.
