Abstract: An IC card unit has a memory, various types of image processing sections, and an IC card interface and, when fitted to an external information processing device, it is contained therein. An image input unit, which has an image forming part and an image pick-up part and which is protruded outward of the information processing device, captures an image of a subject. The image processing sections execute image processing on image data written into the memory, and converts the data into image data optimum for display by an image display of the information processing device. The IC card interface transmits image data that has undergone the image processing to the information processing device side, enabling real-time monitoring. Access from the information processing device side is enabled so that image processing conditions and the like can be set.

Abstract: A method and device for generating a character line of uniform width throughout character size conversion includes predetermining an offset value corresponding to a target line width; adjusting a line width of each character part to the target value without consideration of respective line widths; obtaining coordinate data by reading coordinates of a dot sequence of each character part; reading an offset value corresponding to a character size after coordinate transformation on the basis of the read-out coordinate data. A reference point for a character part from the coordinate data is selected and coordinates of the dot sequence of the character part are transformed to a specified size. A character part font is generated using the transformed dot sequence and superimposing a character part font onto another character part for plotting a character.
