摘要： An object of the present invention is to provide a lens apparatus, a camera system, and a lens driving method capable of achieving both a driving range and a resolution of a focus lens. A lens group having a large number of stopable positions due to a high driving resolution, a long driving range, and the like may be set as a first focus lens group. In this case, depending on communication restrictions (command bit length) between a camera body and the lens apparatus, the lens apparatus may not be driven at the desired position and resolution. Therefore, in the lens apparatus according to the first aspect of the present invention, a lens having a small number of stopable positions is driven as a first focus lens group through communication, and the second focus lens group is driven without being restricted by a communication command through calculation in the lens apparatus. Thereby, it is possible to achieve both the driving range and the resolution of the focus lens.

摘要： At the time of occurrence of camera shake, an angular velocity sensor detects an angular velocity. A rotation angle calculator integrates the angular velocity to calculate angle camera shake. A translational acceleration calculator subtracts an internal acceleration caused during operation of a lens unit from a first translational acceleration detected by an acceleration sensor, so as to calculate a second translational acceleration. A translational velocity calculator integrates the second translational acceleration to calculate a translational velocity. A rotation radius calculator calculates a rotation radius based on the angular velocity and the translational velocity. A shake amount calculator calculates a camera shake amount based on the angle camera shake and the rotation radius. An actuator drives a camera shake correction lens in a direction for canceling the camera shake amount.

摘要： An object of the present invention is to provide a shake correction device, an imaging apparatus, and a shake correction method capable of accurately correcting a parallel shake. According to a shake correction device according to an aspect of the present invention, since a rotation radius to be used in correction of a shake is determined based on a calculated rotation radius and whether or not a polarity corresponding to the calculated rotation radius is different from a polarity corresponding to a rotation radius stored in advance and an image blur is corrected based on a correction amount corresponding to the determined rotation radius, it is possible to accurately correct a parallel shake by taking influence on a polarity of correction due to the updating of the rotation radius into consideration. The “rotation radius stored in advance” may be a fixed value or may be updated during a period of the shake correction. The shake correction can be performed by displacing a shake correction lens and/or an imaging element.

摘要： There are provided a shake detection device of an imaging device, a shake correction device, an imaging device, and a shake detection method which are capable of performing high-accurate shake detection and shake correction. A shake detection device subtracts a reference value from a sensor output of a gyro sensor, and extracts a low frequency component and a high frequency component from a sensor output after the reference value subtraction by using an LPF and a BPF. A first determination unit determines whether or not the imaging device is in a fixed-point imaging state based on the LPF output and the BPF output. In a case where it is determined that the imaging device is in the fixed-point imaging state, a reference value shift amount calculation unit calculates a shift amount (reference value shift amount) for the reference value based on the LPF output for a period during which the determination is performed. A subtraction unit corrects the reference value by subtracting the reference value shift amount from the sensor output after the reference value subtraction. An HPF removes a low frequency noise from the sensor output after the correction of the reference value shift amount. High-accurate shake is detected.
