Abstract: A sheetfed film scanning correction method includes: using a film holding member as a film feeding carrier, wherein the film holding member is fixed and does not move during film feeding, and wherein after the film holding member is inserted into a work position in a scanner, a scanning module of the scanner collects a first correction information under a filmless scanning state and corrects a subsequent scan result according to the first correction information; and setting sheet-feeding rollers of the scanner in idle running as if under a real film scanning state during or prior to collection of the first correction information.

Abstract: A sheetfed film scanning correction method includes: using a film holding member as a film feeding carrier, wherein after the film holding member is inserted into a work position in a scanner, a scanning module of the scanner collects a first correction information under a filmless scanning state and corrects a subsequent scan result according to the first correction information; and setting sheet-feeding rollers of the scanner in idle running as if under a real film scanning state during or prior to collection of the first correction information. By film scanning simulation, the backlight distribution information under the filmless state is real-time collected and used as a correction information, hence implementing the collection of most accurate scan correction information as if under a real scanning environment, particularly applicable to the portable sheetfed film scanner, and eliminating impacts on the correction information caused by temperature change or physical vibration.
