Abstract

An image reproduction apparatus includes an obtaining unit that obtains positions of a subject included in a captured moving image for individual frames, a tracking unit that tracks a movement of the subject specified as a tracking target when the moving image is reproduced, and a control unit that controls a display region using the obtained positions of the subject in a case where a difference between a position of the subject specified as the tracking target and the position of the subject obtained by the obtaining unit at a time of image shooting is within a predetermined range, and controls a display region using the position of the subject specified as the tracking target that is tracked by the tracking unit in a reproduction target frame in a case where the difference is not within the predetermined range.

Claims19

Dependent claims

An image reproduction apparatus comprising:

a processor;
and
a memory configured to store instructions that when executed by the processor cause the processor to:
obtain a captured moving image and information associated with the moving image, the information indicating a position of a first subject in individual frame images of the moving image;
detect a position of a second subject specified as a tracking target in the individual frame images of the moving image by performing a tracking processing in the individual frame images of the moving image;
determine whether a difference between the position of the second subject detected by performing the tracking process and the position of the first subject indicated by the information, in the individual frame images, is within a predetermined range;
and
control a display region of the moving image to be displayed based on the position of the first subject indicated by the information in a frame image in which the difference is within the predetermined range, and control a display region of the moving image to be displayed based on the position of the second subject detected by performing tracking process in a frame image in which the difference is not within the predetermined range when the moving image is reproduced.
