  • a step of, in the case of a color copy mode, compressing an input image using variable length compression, transferring the compressed input image to the memory, and initiating output of the compressed input image from the memory after the transfer of the compressed input image terminates; and

    a step of, in the case of a black-and-white copy mode, transferring an input image to the memory without compressing the input image, and initiating output of the transferred input image from the memory while the input image is being transferred to the memory.
