Abstract
PURPOSE: To make the document processing with saved storage medium possible, by using a magnetic disc as a storage medium of a document, and storing a video signal of an input terminal through shrinking in matching with a graphic display.
CONSTITUTION: A video processor 6 makes signal compresson and saving processing of the signal, in storing a video signal in a buffer area of a main memory 2 to a magnetic disc 41. In the saving processing, the storage value of dot patterns corresponding to the contrast of picture elements is picked up, for example, by adjacent 4-dot and the dots are represented with a dark or light one dot in response to the combination of constrast. Thus, the number of picture elements of a document is saved to a half for both lateral and longitudinal elements, that is, 1/4 in total. When the saved video signals are stored in the magnetic disc 41, the using amount of storage areas for the magnetic disc 41 can be reduced to 1/4.
