A controllerswitches the compressor from the uncompressed output state to the compression output state during a first input vertical blanking period, switches the decompressor from the non-decompression output state to the decompression output state during a first output vertical blanking period immediately after the first input vertical blanking period, and switches the memory from the second mode to the first mode during a first output vertical blanking period.
