Abstract
An image of an original is recorded on a recording medium such as a film based on image signals produced from the original by scanning the original at a predetermined sampling pitch in a main scanning direction and also scanning the original in an auxiliary scanning direction transverse to said main scanning direction. Image information is read from the original at a sampling pitch which is N times (N is a positive integer) larger than the predetermined pitch in the main scanning direction, and image information is read from the original on at least every Nth scanning line across the auxiliary scanning direction, to produce image signals. The image signals are then processed in an image processing mode for sharpness emphasis, for example. The processed image signals are extracted repeatedly N times and recorded on the recording medium in a main scanning direction thereof. Processed image signals on N scanning lines are also extracted which include at least the processed image signals corresponding to an Nth scanning line, and recorded on the recording medium in an auxiliary scanning direction thereof.
