Image data processing apparatus and processing method

摘要

An image data processing apparatus has: an image processing unit outputting image data for display; a compressing unit compressing the display image data; a decompressing unit to which the compression image data is supplied through a communication path and which decompresses the supplied compression image data; an image display unit displaying an image by the display image data from the decompressing unit; and a control unit controlling so as to reduce a clock frequency of the transmitted compression image data when a data amount of the compression image data is smaller than a set data amount by which the data can be reduced to a data amount in which a radiation interference can be permitted.
