Title
(EN) METHOD TO CONTROL IMAGE STABILIZER
(FR) PROCÉDÉ DE COMMANDE D'UN STABILISATEUR D'IMAGE
Abstract
(EN)
A stepper motor is controlled by a driver having a constant and maximum frequency input in order to correct for camera shake. The need for variable frequency devices is eliminated, thereby reducing the cost and complexity of the system.
(FR)
Un moteur pas à pas est commandé par un dispositif pilote présentant une entrée constante et à fréquence maximale pour corriger les vibrations d'un appareil photographique. On élimine ainsi les dispositifs à fréquence variable, ce qui réduit par conséquent le coût et la complexité du système.
