PURPOSE:To attain one-shot color exposure with a simple constitution, by using a color light source emitted uniformly with LEDs or the like of each color as a light source and scanning it with an electronic shutter. CONSTITUTION:A shutter window group 7 is controlled by emitting an LED group 4 of red emission. Further, the control is done that shutter windows among shutter windows 7-1, 7-2, 7-3 corresponding to a image element to be irradiated and shutter windows corresponding to picture elements not to be irradiated. As a result, the exposure is done selectively to a image element required for the red exposure. The control of the amount of exposure is done easily by adjusting a time when a liquid crystal shutter 1 is opened, i.e., the time width when the light transmits throgh the shutter window at each picture element. The exposure of an LED group 5 of green light emission and an LED group 6 of blue light emission are done similarly. |
