Publication number: 20090059070Abstract: Pulse detection portion detects pulses in a horizontal synchronization signal and acquires the occurrence period and the pulse width of the detected pulses. Synchronization pulse decision portion determines pulses, for which the differences between the occurrence period and the reference period and between the pulse width and the reference pulse width are within their respective error tolerance ranges, as synchronization pulses. Mean period acquisition portion obtains the mean period by averaging occurrence periods of the synchronization pulses. Reference period correction portion carries out either or both of correcting the reference period so as to get closer to the mean period and correcting the error tolerance range of the reference period so as to get narrower, under the condition that the occurrence frequency of the synchronization pulses for which the difference between the occurrence period and the mean period is outside of a predetermined tolerance range exceeds a predetermined threshold.Type: ApplicationFiled: July 14, 2008Publication date: March 5, 2009Applicant: NEC ELECTRONICS CORPORATIONInventor: Takeo Matsui
