摘要： Provided are a method and apparatus for generating a synchronization signal. The method includes generating a square wave signal based on a sensing signal, which shows a motion of a scanner, and a specified threshold signal, generating a reference signal having a phase locked reference frequency, based on the generated square wave signal, and generating a synchronization signal synchronized with the motion of the scanner, based on the generated reference signal. By outputting an image signal according to the generated synchronization signal, the motion of the scanner and the image signal can be synchronized.
