Synchronization signal generating device and display apparatus |
摘要 |
According to embodiments, a synchronization signal generating device includes: a cycle measuring unit configured to measure the vertical synchronization interval of the input video signal; a phase difference detecting unit configured to detect a phase difference between an input vertical synchronization signal based on the input video signal and the display vertical synchronization signal; and a vertical cycle determining unit configured to determine a cycle of the display vertical synchronization signal based on a measurement result of the cycle measuring unit and a detection result of the phase difference detecting unit so that the phase difference is decreased within the range of the compensation interval, and to determine 1/n of the cycle of the display vertical synchronization signal as a cycle of an n-times speed vertical synchronization signal.
