PROBLEM TO BE SOLVED: To provide an encoding apparatus, a decoding apparatus, and a switch apparatus that are capable of downsizing hardware resources for signal processing.SOLUTION: An encoding apparatus comprises: a frequency decomposition unit that performs frequency decomposition of image data into a low-frequency component image and a plurality of high-frequency component images; a superimposition processing unit that superimposes the plurality of high-frequency component images subjected to frequency decomposition to generate a single superimposed high-frequency component image; and a transmission unit that transmits the low-frequency component image and the superimposed high-frequency component image as compressed image data. |
