To make the number of interpolation processings to be one when a plurality of images are composited.

A camera block 2 photographs moving images/still images. The MPEG/JPEG compression is performed on the photographed image. The compressed picked up image is recorded in recording medium. A plurality of compressed images recorded in the recording medium are reproduced and expanded. A square pixel transformation, lens distortion correction and a cylindrical transformation for composition are performed on the expanded picked up images. Pasting information when a plurality of the images are pasted is recorded in the recording medium. A plurality of compressed images and a plurality of pasting information are reproduced in the recording medium. A plurality of compressed images are expanded after they are reproduced. The square pixel transformation, the lens distortion correction, the cylindrical transformation and a planarization transformation are performed on a plurality of expanded images at a time. A composited image is displayed. The square pixel transformation, lens distortion correction and a transformation in the optical axis direction can be performed on a plurality of the expanded images at a time.
