ABSTRACT:
A backlight controlled closeup photographing system is proposed, which is designed for use with a multimedia-capable information platform, such as an MMV (MultiMedia Viewer) device, to allow the user to photograph a small object, such as a business card, at close range with intensified illumination on the object for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. The proposed backlight controlled closeup photographing system is characterized by the use of backlight control to increase the intensity of the backlight illumination on the object being photographed for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. Since the intensity of illumination on the object can be increased without using flash unit, the invention is apparently more cost-effective and advantageous to use than prior art.
