Image processing device, display device, image processing method, and computer-readable recording medium

An image processing device comprising:

• a determination unit, included in a CPU-based control unit, configured to determine, based on a plurality of pieces of image data which is generated by continuously taking images of a specified area of field of view and input from an imaging unit, whether the area of field of view of the imaging unit has been changed;
• an image composition unit, included in the CPU-based control unit, configured to superimpose imaging regions of a plurality of images corresponding to the plurality of pieces of image data along a direction in which the area of field of view of the imaging unit has been changed, to generate composite image data when the determination unit determines that the area of field of view of the imaging unit has been changed;
• and
• a display controller configured to cause a display to display a composite image corresponding to the composite image data generated by the image composition unit, wherein the display controller is configured to reduce an aspect ratio or a display area of the composite image, and to cause the display to display the composite image.

• and
• a sensor-based acceleration detection unit configured to detect acceleration of the image processing device, wherein the determination unit is configured to determine whether the area of field of view of the imaging unit has been changed, based on a change in the acceleration detected by the sensor-based acceleration detection unit.
