Abstract:
1. A control method of a variable optical-property element comprising the steps of: (1) acquiring an imaging state of an optical apparatus; (2) changing a function of light deflection of the variable optical-property element to acquire an imaging state of the optical apparatus involved in a change of the function of light deflection; (3) comparing the imaging state after the change of the function of light deflection of the variable optical-property element with the imaging state before a change in optical property to evaluate a degree of improvement of the imaging state; and (4) repeating a sequence of the previous steps (2) and (3) until the imaging state ceases to be improved, in order to compensate a change of the imaging state caused by at least one factor of an ambient change, an individual difference, an object distance, a zoom state, and a change with age, wherein a control signal X(i)(where i is 1 to N and N is a full number of control mechanisms) of an initial value is set to each of control mechanisms Z(i)(where i is 1 to N); the control signal X(i) set to the control mechanism Z(i) is stored in a preset storage area W the imaging state A
