Claim:
A scanner configured to scan mixed sized documents comprising: a first image sensor configured to scan a first image of a first side of a sheet of media to generate first scanned image data; a first local memory device associated with the first image sensor that is configured to temporarily store the first scanned image data as it is being scanned by the first image sensor; a first processor operatively connected to the first local memory device and configured to analyze the first scanned image data stored in the first local memory device and to determine the size of the first scanned image in both a slow scan direction and a fast scan direction; and a main memory device associated with the scanner that is configured to receive the first scanned image data transmitted from the first local memory device and store the first scanned image data, wherein the first processor is configured to transmit the first scanned image data and the determined size to the main memory device once the size of the first scanned image is determined, wherein the first scanned image data, provided by the first image sensor, comprises a series of scanlines, and wherein the size of the first scanned image in the slow scan direction is determined based on the series of scanlines temporarily stored in the first local memory device.
