Abstract
A color image copier operable both in analog and digital modes has a light source having a lamp and a screen with an opening. The screen is rotatable around the lamp so that light emitted from the lamp can be directed selectively to a color original or to a photosensitive film. Light reflected from the color original is received by an image reader which reads image data from the reflected light. The shutter transmits or screen light from the lamp selectively according to data read by this image reader.
