    摘要: A control portion of an optical image pickup apparatus includes a scan driver, a lock-in amplifier, and an A/D converter. The scan driver outputs a predetermined drive signal to a Y-scanning mirror and an X-scanning mirror and scans the Y-scanning mirror and the X-scanning mirror. The lock-in amplifier detects a signal level Vout of a frequency component of the drive signal of the scan driver among signals detected by a detector portion. The A/D converter converts a signal detected by a detector portion and a signal level of the detected signal of a frequency component of a drive signal detected by the lock-in amplifier to digital signals and outputs the digital signals to an image processor. Thus, mirror scan operations of the scanning mirrors can be securely detected.
