Title:
フォーカス制御装置、フォーカス制御方法
Document Type and Number:
Japanese Patent JP4544291
Kind Code:
B2
Abstract:
A focus control apparatus conducts a focus control with respect to an imaging apparatus configured to vary the focal point using a deformable mirror. An imaging unit first obtains image data via imaging elements and imaging optics provided in the imaging apparatus. A controller controls the driving of the deformable mirror such that, during a first image reading period wherein the reading of an image signal is periodically executed by means of the imaging elements, a focus drive state is achieved whereby an in-focus point that has been found in advance is set as the current focal point. During a second image reading period different from the first image reading period, the deformable mirror is controlled so as to achieve a focus drive state for in-focus point search.
