Image blur correction device having image blur-correcting function

An imaging apparatus performs control to display first region information indicating a first region that is a region gazed at by a user and second region information indicating a second region that is a region of a main object within a region of a shot image region so as to be distinguishably superimposed on the shot image. In the above control, the imaging apparatus displays the first region information and the second region information based on the information on the identical position before the first instruction means is operated, and after the first instruction means is operated, the first region information and the second region information are displayed based on information of different positions corresponding to each region.

Image processing apparatus using information of position gazed at by user, imaging apparatus, and control method

An apparatus controls image blur correction by using a first correction unit and a second correction unit having a lower image blur correction performance than that of the first correction unit. The apparatus includes a first acquisition unit configured to acquire a first division ratio, a determination unit configured to determine a final division ratio based on the first division ratio, and a control unit configured to control the first and second correction units based on the determined final division ratio. The determination unit can determine a division ratio where a ratio of the first correction unit is larger than that in the first division ratio, as the final division ratio.

Apparatus, imaging apparatus, interchangeable lens, and method for controlling image blur correction

A control apparatus includes a selection unit that selects a drive mode for first and second correction units based on a focal length, and a control unit that drives the correction units in the selected mode. The first correction unit moves an optical element. The second correction unit moves a sensor. The selection unit selects a first mode if the focal length is a first value, and selects a second mode if the focal length is a second value larger than the first value. With the first mode selected, if a shake amount is a threshold or less, the first correction unit is driven based on the shake amount, and if the shake amount is larger than the threshold, the correction units are driven based on the shake amount. With the second mode selected, the correction units are driven based on the shake amount and a drive ratio.

An image pickup apparatus includes an image sensor configured to capture an object image, and a controller by controlling energizing an actuator for an image stabilization operation that moves the image sensor. The controller switches an energization method for the actuator between a first energization method and a second energization method that has a response distortion of an actuator larger and a ripple current smaller than those of the first energization method, controls energizing the actuator by the first energization method in a first state that does not read a signal out of the image sensor during a charge accumulation of the image sensor, and controls energizing the actuator by the second energization method in a second state that reads the signal out of the image sensor after the charge accumulation.

Image pickup apparatus and its control method that corrects image blurs by moving image sensor

A lens device is able to be installed in an imaging device via a mount part. The imaging device comprises a correction unit performing image blur correction through driving of an imaging element and a control unit which controls driving of the correction unit. The control unit determines a range of an amount of drive control of the correction unit on the basis of a difference between a second length and a positioning accuracy when the imaging element is positioned at the center of the mount part using the correction unit. The second length is obtained by subtracting a diagonal length associated with an imaging range of the imaging element from a first length corresponding to a closest distance to the center of the mount part from a circumference of an imaging circle when viewed from an optical axis direction of an imaging optical system included in the lens device.
