ABSTRACT:
Trichromatic light exposed through a liquid crystal panel upon which liquid crystal shutter elements are two-dimensionally arranged is exposed so as to form an image in the same position on a photosensitive recording medium by moving the photosensitive recording medium opposite the array of liquid crystal shutter elements. For example, the liquid crystal panel is provided with red liquid crystal shutter element rows, green liquid crystal shutter element rows, and blue liquid crystal shutter element rows, each arrayed with m liquid crystal shutter elements in a direction perpendicular to a direction of conveyance of the photosensitive recording medium, these element rows being arranged repetitively in an appropriate order at constant pitch such that (n+2) rows are arranged in the direction of conveyance of the photosensitive recording medium. Exposure through the liquid crystal shutter elements is activated every time the photosensitive recording medium is conveyed by the same distance as the constant pitch.
