In the second interface mode shown in FIG. 7A, data including the eight-bit R data, four-bit G data, and signals VS, HS, and DE is sampled into the internal I/F circuit 62 at the rising edge of the pixel clock signal PCLK. Data including the four-bit G data, eight-bit B data, and reserve bits RSRV0, RSRV1, and RSRV2 is sampled into the internal I/F circuit 62 at the falling edge of the pixel clock
