Abstract:
1. A shake compensation control apparatus configured to compensate for image shake by detecting a shake of an apparatus, the shake compensation control apparatus comprising: a shake compensation unit; a compensation amount calculation unit configured to calculate a compensation amount using a shake amount for the shake-detected apparatus including translational shake produced in a direction of travel of the shake-detected apparatus along a direction that is orthogonal to an optical axis of an imaging optical system; an estimation unit configured to estimate translational shake by inputting a position detection signal for a driven unit and a drive indication signal to the driven unit that configures the shake compensation unit; and a drive unit configured to drive the shake compensation unit in accordance with the compensation amount, wherein the compensation amount for translational shake is calculated based on the estimated amount for translational shake obtained from the estimation unit, and wherein the compensation amount calculation unit is configured to calculate so that the compensation amount for translational shake is reduced if the focal distance of the imaging optical system is increased.
