ABSTRACT:
A scanning device for a color optical reader suitable for high speed single-pass scanning and size reduction, comprising a color charge-coupled-device (CCD) to sense and output red, green and blue signals; a driving circuitry to control the magnitude of the output image signals from the CCD; a color separation circuitry to select the desired color signal; a color pixel arrangement circuitry to convert the color data from a line sequence to a pixel sequence and a positioning mechanism to drive the CCD sensor to a predetermined position.
The present invention can improve the effectiveness of single-pass scanning and output color signals while reducing the cost of the entire system.
