Abstract
A properly-focused image can be constantly obtained even when a cameraman takes a picture of an object which is located within a defocusing area of a zoom lens. A video camera having a zoom lens (,) detects a distance up to an object by a microcomputer (,) on the basis of position informations (S,), (S,) of a variable power lens (,) and a focusing lens (,) of the zoom lens (,). When this distance enters the defocusing area of the zoom lens in accordance with the movement of the variable power lens (,), the variable power lens (,) is fixed under the properly-focused state, and image data representing an object in the properly-focused state is stored in a memory (,). The image data representing the object is decimated, read out from the memory (,) and also interpolated to thereby form image information corresponding to a desired zoom magnification.
