Abstract: Deviations in a panoramic image obtained by compositing multiple images are corrected. An image processing device includes an image data receiving unit, a selection receiving unit, a three-dimensional position obtaining unit, a projection sphere setting unit, and a composited image generating unit. The image data receiving unit receives data of multiple still images, which are taken from different viewpoints and contain the same object. The selection receiving unit receives selection of a specific position of the object. The three-dimensional position obtaining unit obtains data of a three-dimensional position of the selected position. The projection sphere setting unit calculates a radius “R” based on the three-dimensional position of the selected position and sets a projection sphere having the radius “R”. The composited image generating unit projects the multiple still images on the projection sphere and thereby generates a composited image.
