摘要：
A registration correction apparatus having interpolation circuits. The interpolation circuits receives digital sampled pixel signals from at least one channel of a plurality of color signal channels. The digital sampled pixel signals have been obtained by sampling consecutive pixel signals. Each of the interpolation circuits generates a digital pixel signal in a desired position between adjacent two of the digital sampled pixel signals by interpolation processing. The desired position between the two adjacent digital sampled pixel signals is set in accordance with a registration discrepancy among the plurality of color signal channels by a control circuit.
