ABSTRACT:
A double side scanner and method for controlling the scanner. While each of the two scanners of the double side scanner require its own scanning parameters, a user is only required to input one set of parameters for the first side and the second side parameters can be determined from the first side parameters. The second side parameters can be copied from the first side parameters or a transformation process may be performed on the first side parameters in order to obtain the second side parameters. The transformation process can include the changing of margins to account for a binding margin and the changing of the darkness of the scan depending upon the variation of the sensitivities of the light detector of each of the scanners. In order to reduce the amount of time for the scanning process, it is possible to transfer information contained within an image memory to a storage memory at the same time as additional scanning data is being obtained. An error check can also be performed to determine if an overflow condition exists within the image memory.
