ABSTRACT:
A method for adjusting the lens offset of a video camera, in which the offset value of the lens is calculated quickly and exactly during only a small travel of a focus lens and a zoom lens, thereby shortening the time required for calculating the offset value conventionally involving a large travel of the focus lens and the zoom lens, preventing an error, and further curtailing the cost of production.
