Abstract:
1. An image sensing apparatus comprising: a light projector for illuminating an object; an optical system for receiving an image of the object illuminated by said light projector; image sensing means for sensing an object image obtained via said optical system, and outputting the input video signal; focus adjustment control means for adjusting a position of said optical system to an in-focus position by moving said optical system in an optical axis direction on the basis of a specific component in the video signal output from said image sensing means; and recording means for recording a moving or still image of an object on a recording medium in correspondence with the video signal, wherein said focus adjustment control means turns on/off said light projector in synchronism with a vertical sync signal of the video signal and sets an ON period of said light projector at an integer multiple of a vertical sync period of the video signal upon executing focus adjustment with respect to the object.
