摘要:
A method of reading image wherein an original image is read with two different sampling intervals, and undesirable signal components are removed from the read image signals. An apparatus for reading image wherein an original image is read with different sampling intervals by reading devices of two systems; outputs of the reading devices are A/D converted and subjected to an orthogonal function transformation; a converted signal of smaller absolute value is subjected to an inverse orthogonal function transformation to produce a read image signal.
