1. A moving image processing method of an apparatus equipped with a camera, the method comprising: acquiring images at every frame period in a moving image shooting mode; generating metadata of the images; encoding the images into a moving image; storing the generated metadata for each image by detecting a difference between a first metadata of a first image and a second metadata of a second image, and if the second metadata is different than the first metadata, regenerating the second metadata to store the detected difference; and displaying a specific metadata selected among the metadata as a supplementary function of the moving image in a moving image playback mode.
