PROBLEM TO BE SOLVED: To convert the pixel data of a different definition of byte simultaneously with the conversion of the pixel data of different bus-endian by providing a byte swapping/sampling controller and a byte conversion/view selection controller. SOLUTION: The byte swapping/sampling controller 5 is connected between a PCI host bus 4 and an FIFO memory 6, and performs the data conversion between the Big-Endian data and the Little-Endian data, or the data conversion between the system data and the user data. The byte data conversion/view selection controller 7 is connected between the FIFO memory 6 and an SRAM 8, and converts the pixel data of 8 bits-1 byte stored in the FIFO memory 6 to the pixel data of 9 bits-1 byte to output it to the SRAM 8, or converts the pixel data of 9 bits-1 byte stored in the SRAM 8 to the pixel data of 8 bits-1 byte to store it in the FIFO memory 6 in response to the view selected from plural views.
