Abstract
An image data output apparatus of this invention is connected to an image scanner and a data processor (host computer). The image data output apparatus includes interfaces, a data converter, a video signal generator, an LBP (Laser Beam Printer) engine unit, and the like. Multi-level image data scanned by the image scanner is converted by the data converter into data having a desired data format corresponding to the data processor. The converted data is output to the data processor through the corresponding interface. Meanwhile, the scanned image data is also supplied to the video signal generator and is converted to a drive signal for driving a semiconductor laser of the LBP (Laser Beam Printer) engine unit.
