摘要

An image data serial signal output from the parallel-serial converting circuit 21 is converted into a differential amplitude signal by the LVDS transmitter 22 in such a manner that the amplitude of the differential voltage of the image data parallel signal varies depending on the value of the synchronization code serial signal. Accordingly, the signal values of the synchronization code serial signal and the image data serial signal are simultaneously transmitted. On the reception side, the differential amplitude signal in which the amplitude of the differential voltage of the image data serial signal varies depending on the value of the synchronization code serial signal is received by the LVDS receiver 31. The signal values of the synchronization code serial signal and the image data serial signal are separated and output based on a predetermined comparison processing.
