<P>PROBLEM TO BE SOLVED: To correct an error between a plurality of horizonal sync signals being fed for image formation easily. <P>SOLUTION: When power is turned on, an error detecting section 1 stores the delay value of BD-B# for BD-A# and the delay value of BD-A# for BD-B#. Based on the delay values thus stored, a CPU 1 judges a horizonal sync signal having an error in the output timing and an error correcting section 2 corrects the error of output timing for the horizonal sync signal thus judged. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
