Abstract
A zoom tracking method performed by a control unit of a zoom camera includes operations (a) through (c). In operation (a), the control unit determines a focusing progress state at a time when a zooming start signal is received. In operation (b), the control unit narrows an estimated range of a subject distance or estimates the subject distance, according to the focusing progress state. In operation (c), the control unit performs focusing for a zoom magnification according to the narrowed estimated range or the estimated subject distance.
