This page presents advices on what a customer should check before to chose.
Why is the Digitizing Line better than other solutions ?
No missing of pages or turning more than one page at a time Not a short lifetime product No use of low end CCD cameras and optics No format restrictions. Up to 2xA2 and thickness up to 15 cm (6 in) No use of clamps to hold the book because they may damage the cover No interferences or external objects on the image No need for operator in attendance on the process No way to damage a book. Preserves the condition of the original or unique copy.
Turn page process is faster : 2.4 seconds per sheet = 1.2 seconds per page Constant process reliability operating 24 hours a day Scanned image is continuous over both pages presented to the camera The light is uniform over the whole surface of the document as the source moves with the camera Higher image quality and less page curvature as pages are presented flat under the glass Measures parameters of the book and automatically adapts to manage it in optimal conditions If pages are stuck together, automatically retries to separate them Use of recipes for scanning collections of similar books Soft-cover books can be scanned (not limited to hard-covers) What are main differences in camera technologies of linear CCD versus matrix CCD ?
Current technology linear CCD cameras produce an equivalent matrix of pixels that is at least 3 times more dense than current technology matrix CCD cameras.
Linear CCD color cameras present 3 RGB sensors producing 1 RGB pixel in front of 1 optical pixel. Matrix CCD color cameras present 4 color sensors producing 1 RGB pixel in front of 4 optical pixels. Therefore the resolution of matrix CCD color cameras is 2 times smaller than a linear CCD color camera.
What are differences of speeds for scanning in Color RGB versus Grey Levels ?
For a given resolution, scanning in Color RGB generates 3 times more data (typically 24 bits) than scanning in Grey Levels (typically 8 bits). Therefore the speed of scanning in Color RGB may be slower than the speed in scanning in Gray Levels.
Is it possible to scan any book at maximum speed ?
Separating pages at a constant speed is a challenge. The structure of the book, the paper and the way a book has been conditioned, may influence processing speed. It makes no sense to mention that any book can be scanned at a maximum speed.
