An image display device capable of saving time and effort required for viewing image data, to which image rotation information unintended by a user is added, in a desired orientation. An acceleration sensor detects an attitude of the image display device. A system controller controls the direction of display of an image based on the image rotation information and the detected attitude of the image display device. When the image display device is rotated from a state where the long side of the image displayed on a monitor and that of the monitor do not match each other, the system controller rotates the image such that the long sides of the image and the monitor match each other, and then, the system controller restricts rotation of the displayed image. |
