<p>There is provided a multiplex apparatus which multiplexes extended horizontal and vertical high-frequency components to a basic video signal, the extended horizontal and vertical high-frequency components having spatial frequencies higher than those of the basic video signal. The basic video signal and the extended horizontal and vertical high-frequency components are derived from an image. A control signal is generated corresponding to the image. Spatial frequency bands of the extended horizontal and vertical high-frequency components are converted to that of the basic video signal, respectively. Responding to the control signal, band widths of the extended horizontal and vertical high-frequency components having the spatial frequency bands converted are changed, respectively. Then, the extended horizontal and vertical high-frequency components each having the spatial frequency band width changed are multiplexed. <IMAGE></p> |
