Devices and methods are disclosed for the high speed digitization of large collections of thin, flexible sheets such as photographic prints. The sheets are inserted into transparent pockets on an elongated belt, and the belt is driven rapidly without stopping past a high speed digital camera. A glare reduction means is employed to avoid glare off the transparent pockets, and motion blur is eliminated through the use of high speed strobe illumination or a high speed shutter. The invention can be commercialized by having a customer load the belt with photographs (or other thin sheets) and deliver the belt to a processing location. Digital images of the sheets may then be provided to the customer, and the original sheets may be left in the pockets on the belt for convenient storage.
