摘要:
A photographic image acquisition device is disclosed including a light source in the form of an LED chip array having a plurality of LED chips, a photographic medium positioning member for positioning a photographic medium at a predefined position, a projecting lens for projecting the image information on the photographic medium onto a detecting member and for exposing said detecting member, and a light transmitting and averaging member positioned between the LED chip array and the predefined position. The device provides faster image acquisition with a relatively simple mechanical construction.
