ABSTRACT:
According to this invention, when n-value image data is transmitted, data associated with its compression method is transmitted to a reception-side apparatus, so that the reception-side apparatus can perform proper image processing. More specifically, there is disclosed an image transmission method having the following advantages. That is, when a reception-side apparatus can select one of a plurality of image processing methods, it selects a processing method matching with an n-value compression method, and properly reproduces an m-value image. Even when the reception-side apparatus does not have an image processing method matching the n-value compression method of a transmission-side apparatus, that fact can be communicated to the transmission-side apparatus or to an operator of the reception-side apparatus, so that operators of the transmission- and reception-side apparatuses can recognize that a color difference will occur between the transmission- and reception-side apparatuses, and an effective countermeasure can be taken.
