Abstract: An image tracking apparatus, which tracks a subject in a moving image, comprising: an image acquisition device that acquires image data indicating the moving image; a first detector that detects a first area of a subject in acquired image data to track the first area in the moving image; a second detector that detects a second area of a subject in the image data to track the second area in the moving image; and a controller that tracks the subject by switching between a tracking result of the first detector and a tracking result of the second detector. The first and the second detector operate independently. The controller tracks the subject using the tracking result of the first detector when the first area is tracked, and tracks the subject using the tracking result of the second detector when the first area is not tracked and the second area is tracked.

Abstract: An image processing apparatus includes an image processor, a display unit, an operation unit, and a controller. The image processor combines data of a plurality of images to generate data of a still image deeper in depth of field, the plurality of the images that are generated by shooting an object image while changing a focus position. The display unit displays a range designation screen displaying an image together with a plurality of image areas. The operation unit receives a designation, performed by the user, of an image area in the range designation screen. When a first and a second image area in the range designation screen are designated by the user, the controller sets a combining range having a focus position located between the first and the second image area. The display unit performs a first display-highlighting on the image areas included in the combining range set.

Abstract: The image capture device includes an optical system including a focus lens, a CCD that captures a subject image input via the optical system and generates an image signal, an image processor that generates image data by performing predetermined processing on the image signal generated by the CCD, and a controller. The controller performs a scan operation for detecting a focus position for each of a plurality of partial regions of image data while moving the focus lens and records a moving image by moving the focus lens while switching a moving speed of the focus lens based on information on the focus position obtained for each of the plurality of partial regions as a result of the scan operation. The plurality of partial regions is a plurality of regions obtained by dividing an image region of the image data.

Abstract: An imaging device includes: an imaging sensor; an optical system that changes an image magnification of a object image according to a position of a focus lens; and a controller that causes the imaging sensor to generate the plurality of pieces of image data by causing the imaging sensor to pick up the object image while moving the focus lens to generate still image data based on the plurality of pieces of image data. When generating the still image data, the controller finds an entrance pupil position of the optical system based on the position of the focus lens for each of the plurality of pieces of image data, and calculates an image magnification change rate indicating a change of the image magnification of the object image based on the found entrance pupil position, magnifies each of the plurality of pieces of image data such that a size of the object image indicated by each of the plurality of pieces of image data becomes a predetermined size, based on the corresponding image magnification change rate, and synthesizes the plurality of pieces of magnified image data to generate the still image data.

Abstract: A generator generates attribute information regarding a video image, which is captured by an imaging unit by capturing a plurality of capture directions, on a predetermined unit of video content. A composition map generator extracts a predetermined object, based on the attribute information of the video images captured in the plurality of capture directions within a predetermined period, and generates a composition map indicating a position of the extracted object. A comparator determines priority orders in the respective pieces of shooting of the respective capture directions based on a comparison result obtained by comparing pieces of the attribute information, for each of the capture directions and based on the attribute information included in the composition map. A camera work controller determines a next capture direction based on the priority orders, and controls operations of the imaging unit and a camera pantilter based on the determined capture direction.
