An image processing apparatus prevents a panoramic image or a sequence of consecutive images from being partially lost due to the accidental erasing of an image composing the panoramic image or the sequence of consecutive images. When the user selects an image to be erased from a memory, additional information about the selected image is read and then it is determined whether or not the selected image is a part of a panoramic image or a sequence of consecutive images with reference to the additional information. If no, the selected image is erased. If yes, a display indicates that the selected image is a part of the panoramic image or the sequence of consecutive images in order to request the user to determine whether to collectively erase all the image data relating to the panoramic image or the sequence of consecutive images including the selected image. Then, all the image data are collectively erased if the user determines so.
