A period when a relative movement between a document, and each of the pixel rows by a certain distance in the vertical direction is made is defined as a frame period, and the frame period is divided into a given number (i) of H periods. A certain H period is allocated as a readout period of each of the pixel rows so that each of the pixel rows reads an identical line of a document, depending on a vertical resolution set by a resolution setter. |
