Image retrieval method and apparatus wherein for retrieval of a plurality of images, a sub-image of each image is specified and extracted, reference data such as memo data related to each sub-image is stored, and the sub-image and the memo data related thereto are combined and outputted as desired, thereby simplifying the retrieval of the plurality of images. Specifically, a sub-image which is the most characteristic to each image is extracted and combined with a memo data to thereby provide a clear clue to the image extraction. The number of specified sub-images is freely increased without rewriting original image data stored in an image file and image retrievel is settled by using a memo image and a cutout sub-image both having a less amount of data than the entire image, so that applications to a storage medium which is not rewritable, for example, an optical disc can be ensured with high response image display.
