A moving image processing apparatus includes a shake amount acquisition unit configured to acquire and output a shake amount, a period acquisition unit configured to acquire a period during which a change in composition occurs in a video image, a setting unit configured to set a size and position of a cut-out range of image data for each frame of the video image based on the shake amount output from the shake amount acquisition unit, and a correction unit configured to change, based on the shake amount, the position of the cut-out range set by the setting unit in such a way as to correct shaking of the video image.

An image processing apparatus comprises the following units. A dividing unit divides a frame of a moving image into a changing area in which there is an active object and a changeless area in which there is a stationary object. A generation unit generates a still image by compositing an area corresponding to the changeless area in each of X frame(s) (where X is an integer of 1 or more) among a plurality of frames included in the moving image and an area corresponding to the changing area in each of Y frames (where Y is an integer greater than X) among the plurality of frames.

In an imaging device, a first motion information acquisition unit acquires motion information of the imaging device, and a second motion information acquisition unit acquires motion information of an external device. A shake information generation unit performs a process of subtracting the motion information of the external device from the motion information of the imaging device on the basis of the acquired motion information of the imaging device and the external device. Image blur correction information is generated from the subtracted motion information. An image blur correction control unit performs driving control of a correction lens of an optical system and a movement mechanism unit of an imaging element in accordance with the image blur correction information from the shake information generation unit.

A monitoring camera sets ON or OFF of swing correction in accordance with setting information about whether or not the swing correction of an image (that is, captured image) captured by an image sensor is performed, and corrects swing by cutting out a part of the captured image based on a swing detected value of a vibration sensor in a case where the swing correction is set ON. The monitoring camera outputs the captured image while maintaining a state thereof in a case where the swing correction is set OFF.

A digital camera that corrects an image blur of a captured image by driving a shift lens group is provided. The digital camera determines a specified region of the captured image, and when a panning shot will be performed, the digital camera drives the shift lens group based on a movement of the specified region to execute control to correct an image blur for the specified region, and subsequently executes focus control for focusing on an object.

An image capturing apparatus is configured to have an interchangeable lens detachably mounted thereto, and is provided with an image capturing unit configured to obtain a captured image, a synchronous signal generation unit configured to generate a synchronous signal for reading out the captured image continuously from the image capturing unit, a communication unit configured to transmit the synchronous signal to the interchangeable lens, and a measurement unit configured to measure a delay time from a timing at which the synchronous signal is generated until a timing at which the communication unit transmits the synchronous signal to the interchangeable lens, the delay time being transmitted to the interchangeable lens by the communication unit together with the synchronous signal.

An image stabilization apparatus includes: a first calculation unit that calculate an angular velocity; a second calculation unit that calculates a motion vector of an object; a third calculation unit that calculates a current position of an image stabilization unit; a fourth calculation unit that calculates an angular velocity of a motion of the object; and a control unit. The control unit controls, before the image capturing apparatus is released, the image stabilization unit so as to correct an image blur, moves, an output position of an image from the image capturing unit, and controls, after the image capturing unit has started exposure, so as to correct an image blur based on an angular velocity of the image capturing apparatus and an angular velocity of the object.

The image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit. The system control unit selects one of rotation axes based on a usage state of a digital camera, and calculates a shift blur amount generated in a direction by rotation of the digital camera around a second axis and a shift blur amount generated in a direction by rotation of the digital camera around a first axis based on distances from the selected rotation axis to the acceleration sensor, angular velocities, and accelerations.

An image blur correction device is configured to correct a blur of an imaging apparatus that includes an image sensor that images a subject through an imaging optical system. An image blur correction device includes an acceleration sensor that detects accelerations in two directions, an angular velocity sensor that detects an angular velocity of the imaging apparatus around a rotation axis parallel to the optical axis, a rotational acceleration component calculator that calculates rotational acceleration components which are generated by rotation of the imaging apparatus around the rotation axis based on an output of the angular velocity sensor, and a blur corrector that corrects blurs of the imaging apparatus based on the rotational acceleration components and the accelerations. The blur corrector corrects the blurs based on a member of the imaging apparatus that is used for an imaging of the imaging apparatus.

Stabilizing an image capture device includes stabilizing the image capture device as the image capture device captures images; responsive to detecting an exceptional activity, stopping the stabilizing of the image capture device; and after the exceptional activity is completed, stabilizing the image capture device again. An image stabilization device for stabilizing an imaging device includes a processor that is configured to set at least one of a pitch angle or a roll angle of the image stabilization device to respective constant values and allow a yaw angle of the image stabilization device to vary; while the yaw angle is less than a threshold angle, maintain the yaw angle at a constant relative to a reference platform; when the yaw angle reaches the threshold angle, stop keeping the yaw angle relative to a reference platform constant; and set the yaw angle to follow a direction of motion of the reference platform.
