CAMERA AND DEVICE FOR SWITCHING OPTICAL FILTERS

摘要

To provide an optical filter switching device for a camera in which a clear image can always be obtained during the day and at night. In a cameral in which an image is formed on an image pick-up element (2) through a lens (1a) provided on a camera body (1) and is converted into an electric signal through the image pick-up element (2), thereby obtaining an image signal, optical filter switching means (3) for switching optical filters (3a) and (3b) depending on a level of the image signal is provided on a front surface of the image pick-up element (2) and a clear image can always be obtained during the day and at night. Therefore, in the case in which such a camera is used for a surveillance camera, the reliability of a monitoring system can be enhanced.
