According to the present invention, based on positional information contained in an index record, a recording position of an image data on the file medium corresponding to a position in an original image specified by the user for a display or to {HEAD ~ a partial area} of {TAIL ~ a reproduced image} is obtained so as to selectively read out only a data portion at a position corresponding to the partial region from each image record on the file medium, which minimizes the quantity of image data to be read and hence reduces the image display cycle
