Image data from an upper apparatus is compressed by a compressing unit, the compressed image data is transferred to a display apparatus by a printer interface of a low speed, and the original image data is reconstructed by a decoding unit and displayed. The display apparatus is a projector and auxiliarily displays a second picture plane into a first picture plane for presentation by an independent liquid crystal panel. A phase transition type liquid crystal panel of a number of pixels and a high resolution is used to display the first picture plane and the image data is compressed and transferred and is displayed. As a second picture plane, a personal computer picture plane is transferred and displayed as it is.
