￿¡ Data compression unit

Using an optional data compression unit, it is possible to compress the scanned image data by methods known as MH, MR, and MMR. This saves memory capacity.

￿¡ Video interface unit

The optional video interface unit provides a video interface connector.

￿¡ Image processing unit

The optional image processing unit adds the following image processing functions.

Dynamic threshold:

The scanned image is automatically binalized by an appropriate threshold. The scanner dis- criminates a background color and decides the threshold to use.

Auto photo/letter:

The scanner automatically detects letter areas and photo areas of the original. The letter areas are scanned in binary, and the photo areas are scanned in halftone.
