Title: Image reader
Inventor: SATOMURA SEIICHIRO
IPC: H04N1/04
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent color smear in an auxiliary scanning direction by delaying the start position of a control pulse in a means which performs light control of a white light source for original irradiation different in the afterglow characteristics of respective colors through the use of a pulse width modulation system when the image information of an original is formed on a plurality of line sensors by an image forming optical system. SOLUTION: Image information on an original by the lighting of a fluorescent lamp is image-formed on a plurality of line sensors by an image forming optical system. In a light control signal, not a whole Hsync period but a phase is delayed by about π/2 and it is started as illustrated. Even if the duty of the light control signal changes, the start of a pulse width modulation signal is in a position which is always delayed from the head of Hsync by π2. Consequently, afterglow quantity is distributed to the front and the back of a light emitting area and they are averaged. Centroid shift quantity generated by the afterglow characteristic of the fluorescent lamp is reduced from d2 to d1. Thus, color smear at the image reading in an auxiliary scanning direction is practically eliminated.
