Abstract:
An image processing apparatus which scans a manuscript in order to read-out an image of said manuscript comprising:a storage means for storing an image data corresponding to one line in a horizontal scanning direction; a first generation means for generating prescribed reference pulse; a second generation means for generating a thinned-out pulse obtained in such a way that said reference pulse is thinned-out with a prescribed rate; a read-out means for reading-out said image data stored in said storage means according to either said reference pulse or said thinned-out pulse; an output means for outputting said image data read-out by said read-out means according to either said reference pulse or said thinned-out pulse; a first changeover means for changing to be supplied either one between said reference pulse and said thinned-out pulse to said read-out means; a second changeover means for changing to be supplied either one between said reference pulse and said thinned-out pulse to said output means; a control means for controlling scanning speed in vertical scanning direction according to scale factor in the vertical scanning direction; and a thinning-out means for thinning-out said image data stored in said storage means in every one line unit according to scale factor in said vertical scanning direction.
