1. An image display device comprising:
- a front face;
a back face which faces in a direction opposite to a direction in which the front face faces;
a display portion configured to display an image expressed by image data wherein a display face of the display portion is provided on the front face of the image display device, and faces in the same direction as the front face of the image display device;
a CPU;
a position sensor which is configured to function in cooperation with the CPU to be operable as a positional information acquiring unit which acquires positional information indicating a current position where the image display device is arranged;
a direction sensor which is arranged in the image display device and is configured to function in cooperation with the CPU to be operable as a direction information acquiring unit which acquires a current direction in which the back face of the image display device is facing;
an input device for inputting image data;
wherein the CPU is configured to be operable as a search unit which is operable to search for image data input via the input device which is associated with positional information satisfying search conditions from among a plurality of pieces of image data, wherein the search unit uses, as a search condition, positional information of a location existing in the current direction acquired by the direction information acquiring unit from the current position of the image display device indicated by the positional information acquired by the positional information acquiring unit; and
wherein the CPU is configured to cause an image expressed by the image data found by the search unit to be displayed on the display portion.

Abstract
It is an object of the present invention to search for image data with an intuitive operation to which active elements are added.
A digital photo frame 1 searches a non-volatile data base memory 15 or a network for image data based on parameters respectively related to a position and a direction in which the digital photo frame 1 is arranged, a distance or a depth from the digital photo frame 1, and time. The digital photo frame 1 displays an image expressed by the image data thus searched.
