Abstract: A scanner is provided with an image memory for storing therein image data read from an original by an image sensor, an image processing portion for effecting image processing on the image data, and a sending portion for sending the image data to an external equipment. The image processing portion is disposed in a route along which the image data is forwarded from the image memory to the sending portion, and the contents of the image processing by the image processing portion is made changeable over. The external equipment is provided with an image analyzing portion for obtaining first image data image-processed in a first image mode from the scanner and analyzing it, and detecting the state of the original (such as whether the original is a white sheet) from which the first image data has been read. On the basis of the result of the detection by the image analyzing portion, second image data image-processed in a second image mode is obtained from the scanner.

Abstract: The present invention relates to a data processing device which is also used as an interface device for connecting an external storage device to a host computer to which a card form of storage device can be connected, the external storage device differing in data format from the card form of storage device. The data processing device includes a connection unit for connecting the external storage device to the host computer, the connection unit being able to be removably fitted into a slot which is provided in the host computer and into which to removably fit the card form of storage device, and a converting circuit for converting data, which is to be outputted from the host computer in a data format conforming to the card form of storage device, into a data format conforming to the external storage device, as well as for converting data read out from the external storage device into the data format conforming to the card form of storage device.
