1. A method of reproducing image data in a network projector system that has at least one server connected to a network, and at least one projector connected to the at least one server through the network, the method comprising the steps of:

  • (a) preparing data that includes image data of an image to be reproduced by the at least one projector and image controlling data at the at least one server;

    (b) establishing communication between any projector of the at least one projector and at least one specified server of the at least one server through the network; and

    (c) transferring the data that includes the image data and the image controlling data from the at least one specified server with which communication has been established to the projector;

    wherein processing performed, in the projector which has received the data which has been transferred, comprises the steps of;

    (d) determining image data necessary for the image to be displayed based upon the image controlling data;

    (e) checking whether the necessary image data is stored on a memory medium;

    (f) determining whether there is sufficient empty space available in the memory medium to store the necessary image data if the necessary image data is not stored in the memory medium;

    (g) detecting data that is unnecessary for the image to be displayed, and deleting the unnecessary data from the memory medium when the empty space in the memory medium is insufficient to store the necessary image data;

    (h) receiving the necessary image data from the specified server;

    (i) storing the image data which has been received in the memory medium;

    (j) processing the image data which has been stored and forming an image; and

    (k) displaying the image which has been formed.
