Photographic film scanner with variable exposure settings

摘要

An imaging system which can scan and capture high-quality digital images at high speeds, including the ability to adjust the exposure setting of the digital camera to accommodate the variable film exposure experienced with consumer film. According to a preferred embodiment of the invention, this is achieved through the use of a pre-scan function which determines film density and permits the exposure settings of a line-scan camera to be adjusted on a frame by frame basis during a frame gap in response to the predetermined density for each frame.
