A color pen-shaped scanner has been developed. A compact imaging configuration, SOFI (Single Optical Fiber Imaging), enables us to contain a linear image sensor, an array of red, green and blue light emitting diodes (LEDs) and all the other components in a pen-shaped housing. Color imaging is realized by turning on one color LEDs at a time, storing the sensor output as one color information of the input line and repeating this process for the other two color LEDs. The width of the scanner is 13mm and the input width is 110mm. The maximum input speed is 2cm/sec at 200dpi resolution. The average color difference for 21 color patches is 16.0 and 7.4 before and after the matrix correction, respectively.
