Abstract
An image conversion apparatus for converting and outputting the spatial resolution, temporal resolution, or image quality of compressed image data input thereto is provided. A compression-coded frame-unit image signal An input from the input signal line is changed to real-time image data Rn by an image decoding unit. A image coding unit then converts the real-time image data Rn to compressed image data comprising fewer picture elements and having a different spatial or temporal resolution different from that of the real-time image data Rn.
