Abstract: A method for processing images comprises the steps of performing the reception of data through the net work, inputting image data obtainable in accordance with the designated input mode, managing the storage of the data received in the receiving step and the image data inputted in the input step to the memory, and intervening between the operations of the reception step and the input step in accordance with the storage management in the controlling step. With the method thus structured, the compression ratio of the input image is heightened by changing the current photographing mode if the added value of the estimated reception data through communicating means and the data side of photographed image predetermined by the current photographing mode should exceed the remainders of memory in the storage, hence making it possible to implement the compatibility of immediacy between the image input and the communication by dealing with any sudden reception during photographing.
