Video camera with recorder-reproducer and control thereof

摘要

A video camera with a recorder-reproducer comprises an OSD IC and an LCD panel device that includes a synchronization signal separation circuit, an LCD panel, a signal line, and an LCD controller made of a horizontal synchronization separation circuit and a PLL circuit. The horizontal synchronization separation circuit separates a horizontal synchronizing signal from a composite synchronizing signal received from the synchronizing signal separation circuit. The PLL circuit generates a reproduced horizontal synchronizing signal in synchronism with the horizontal synchronizing signal separated by the horizontal synchronization separation circuit. The reproduced horizontal synchronizing signal output by the PLL circuit is fed to the LCD panel via the signal line. Although the PLL circuit is intended to supply the reproduced horizontal synchronizing signal primarily to the LCD panel, this signal is also fed to the OSD IC via a terminal and a switch.
