A processor of an imaging apparatus including an imaging element that images a subject through an imaging optical system is configured to: perform a recording control of performing one of: first processing as defined herein; and second processing as defined herein; perform an image shake correction control of correcting an image shake of a captured image output from the imaging element by moving one or both of the imaging element and a lens included in the imaging optical system; perform image processing of generating a live view image for displaying a subject image formed in the second region on a display unit; and perform a control of setting, in a case of performing the first processing, a movable range of at least one of the imaging element and the lens in the image shake correction control to be larger than in a case of performing the second processing.

A motion detecting section detects a change in relative position relation between a subject and an image capturing section performing a rolling shutter operation. A thinning-out setting section sets a thinning-out amount of a line thinning-out operation of the image capturing section according to the detection result obtained by the motion detecting section. A recognition processing section performs subject recognition in an image obtained by the image capturing section, by using a recognizer corresponding to the thinning-out amount set by the thinning-out setting section. The change in relative position relation is detected based on motion of a moving body on which the image capturing section is mounted, an image capturing scene, an image obtained by the image capturing section, and the like. Line thinning-out is performed during the rolling shutter operation, and the thinning-out amount is set according to the detection result obtained by the motion detecting section.

An image pickup apparatus that eliminates manual change of an image pickup direction during an image picking up operation and can easily obtain an image that records experience while focusing attention on the experience. A detection unit is worn on a body part other than a head of a user. An image pickup unit is worn on a body of the user. A memory device stores instructions. A processor executes the instructions to: detect an observation direction of the user by the detection unit, pick up an image by the image pickup unit, output an image in an image recording frame corresponding to the observation direction, determine the image recording frame so that a part of the body of the user will not appear in an output image.

An image pickup apparatus that eliminate manual change of an image pickup direction during picking up an image and can easily obtain an image that records experience while focusing attention on the experience. An image pickup unit picks up a wide-angle image. A face direction detection unit detects a direction of a face of a user. A user movement detection unit detects a movement of the user. A processor executes a set of instructions stored in a memory device to detect a vertical movement and/or a horizontal movement of the face based on an output of the face direction detection unit, determine a position and/or a size of an extraction image extracted from the wide-angle image based on the direction and movements of the face and the movement of the user, and extract the extraction image from the wide angle image with the position and/or the size determined.

An encoding method, playing method and apparatus for image stabilization of panoramic video, and a method for evaluating image stabilization algorithm are provided. The image stabilization method for the panoramic video is applicable to an electronic apparatus including a processor. In the method, a plurality of image frames of a panoramic video is captured, and each image frame is transformed into a plurality of projection frames on a plurality of faces of a cubemap. Then, variations of triaxial displacements and attitude angles between the projection frames transformed onto each of the faces and adjacent in time are calculated. The variations of triaxial displacements and attitude angles are smoothed and recorded as movement information. While playing the panoramic video, the panoramic video is corrected by the movement information and played. Thus, it is possible to reduce the amount of calculation required for the stabilization calculations on the captured video.

A control apparatus comprising at least one processor or circuit configured to execute a plurality of tasks includes a first acquisition task configured to acquire information on image shift sensitivity relative to decentering of an image stabilizing optical system, the information being associated with an image point position of an image pickup optical system, the image pickup optical system including the image stabilizing optical system configured to perform image stabilization, and a second acquisition task configured to acquire a first image stabilizing driving amount of the image stabilizing optical system during the image stabilization. The second acquisition task is configured to acquire the first image stabilizing driving amount associated with a predetermined image point position by using the information on the image shift sensitivity associated with the predetermined image point position.

A video may be captured by an image capture device in motion. A stabilized view of the video may be generated by providing a punchout of the video. The punchout of the video may compensate for rotation of the image capture device during capture of the video. The size of the punchout of the video may be changed based on different rotational positions of to provide a view that includes different extents of the captured visual content. The changes in the size of the punchout may simulate changes in zoom of the visual content.
