Abstract
An optical apparatus includes a variable optical-property element, a driving circuit driving the variable optical-property element, and an image sensor. In order to compensate a change of an imaging state caused by at least one factor of temperature, humidity, a manufacturing error, a change of an object distance, and a zoom state, photographing is performed while referring to a look-up table to change driving information provided to the variable optical-property element, and the driving information that the high-frequency component of a photographed image is practically maximized is assumed so that the variable optical-property element is driven by the driving information to perform photographing.
