Abstract
A zoom tracking controller includes a lens position acquiring unit that acquires the positions of a first zoom lens and a first focus lens, a cam curve storage unit that stores at least one reference cam curve, a normalizing unit that normalizes the acquired first zoom lens position and first focus lens position to a zoom lens position and a focus lens position on one of at least one reference cam curve according to a first cam curve and the reference cam curve, a focused lens position determining unit that determines second zoom lens and second focus lens positions on a second cam curve from the normalized zoom lens and focus lens positions according to the second cam curve and reference cam curve, and a lens controller that respectively moves the second zoom lens and second focus lens to the determined second zoom lens position and second focus lens position.
