Abstract

A reproducing apparatus, an image data reproducing method, a program, and a storage medium each detects an attitude state of the reproducing apparatus, extracts a part of an area of image data obtained by an image pickup device, and reproduces the part of the area of the extracted image data. According to the detection result, the part of the area of the image data is changed to another part of the area and rotation processing of another part of the area is performed, thereby reproducing the another part of the area which was subjected to the rotation processing.
