An image processing apparatus comprising: combining means configured to combine a plurality of images to generate a combined image; and control means configured to record the combined image generated by the combining means on a recording medium, and configured: if the combined image, generated by the combining means, is generated by combining a plurality of captured images which has not yet been stored in the recording medium, and: if the plurality of images used for combining during imaging have substantially the same imaging conditions and angles of view, to attach first combination classification data, as identification information that indicates the plurality of images used for combining during imaging have substantially the same imaging conditions and angles of view, to the recorded combined image, and if the plurality of images used for combining during imaging do not have substantially the same imaging conditions or angles of view, to attach second combination classification data, as identification information that indicates the plurality of images used for combining during imaging do not have substantially the same imaging conditions or angles of view, to the recorded combined image, wherein if the combined image, generated by the combining means, is generated by combining a plurality of stored captured images already recorded on the recording medium, the control means is configured to attach the second combination classification data, as the identification information, to the recorded combined image regardless of whether the plurality of images used for combining have or do not have substantially the same imaging conditions and angles of view. combining means configured to combine a plurality of images to generate a combined image; and control means configured to record the combined image generated by the combining means on a recording medium, and configured: if the combined image, generated by the combining means, is generated by combining a plurality of captured images which has not yet been stored in the recording medium, and: if the plurality of images used for combining during imaging have substantially the same imaging conditions and angles of view, to attach first combination classification data, as identification information that indicates the plurality of images used for combining during imaging have substantially the same imaging conditions and angles of view, to the recorded combined image, and if the plurality of images used for combining during imaging do not have substantially the same imaging conditions or angles of view, to attach second combination classification data, as identification information that indicates the plurality of images used for combining during imaging do not have substantially the same imaging conditions or angles of view, to the recorded combined image, if the plurality of images used for combining during imaging have substantially the same imaging conditions and angles of view, to attach first combination classification data, as identification information that indicates the plurality of images used for combining during imaging have substantially the same imaging conditions and angles of view, to the recorded combined image, and if the plurality of images used for combining during imaging do not have substantially the same imaging conditions or angles of view, to attach second combination classification data, as identification information that indicates the plurality of images used for combining during imaging do not have substantially the same imaging conditions or angles of view, to the recorded combined image, wherein if the combined image, generated by the combining means, is generated by combining a plurality of stored captured images already recorded on the recording medium, the control means is configured to attach the second combination classification data, as the identification information, to the recorded combined image regardless of whether the plurality of images used for combining have or do not have substantially the same imaging conditions and angles of view.
