ABSTRACT:
According to the present invention, an image processing/converting section comprises a pixel position calculating section, a pulse width changing section, a pixel value shifting section, and a recording device driving pulse generating section. The pixel position calculating section generates main scanning direction coordinate information and sub-scanning direction coordinate information on the basis of parameters input into the pixel position calculating section resistor setting values xreg252 and yreg254, a main scanning direction clock signal, and a sub-scanning direction clock signal. The pixel value shifting section calculates an output value of the processed pixel after shifting operation on the basis of the main scanning direction coordinate information, the sub-scanning direction coordinate information, and the pulse width data which is obtained by converting input data of a pixel to be processed by the pulse width changing section. The recording device driving pulse generating section generates a recording device driving pulse on the basis of the reference position signal and the output value of the pixel to be processed.
