Device for correcting non-linearity of scanner in image forming apparatus |
摘要 |
A device for correcting the non-linearity of a scanner comprising: a reset pulse generator for generating a reset pulse with a predetermined pulse width in synchronization with a scanning start signal generated corresponding to an input photosensitive belt sensing signal; an address generator for outputting an address by being reset by the reset pulse; a look-up table, that is initiated by the scanning start signal, for receiving an address from the address generator and for outputting information corresponding to the address in the form of digital data; and a converter for outputting a synchronizing signal with a frequency corresponding to the digital data from the LUT. Another aspect of this invention is a method for correcting the non-linearity of a scanner.
