<p><P>PROBLEM TO BE SOLVED: To provide a controller device or the like for improving usability by exactly eliminating a synchronization error that affects a product function about a line synchronization error resulting from the contention of a shared memory between a plurality of LSIs. <P>SOLUTION: A line error determination circuit 11 is provided with a line error counter 12, a line error pixel counter 13, a determination condition setting circuit 14 and an error generation circuit 15. The determination condition setting circuit 14 sets a determination condition for determining a line synchronization error that affects a product function, determines a line synchronization error with reference to a synchronization error from the line error counter 12, and a line error pixel and a determination condition from the line error pixel counter 13, and outputs a determination result to the error generation circuit 15 to generate synchronization error interruption. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
