1. A semiconductor device, comprising:
a first input unit configured to receive a first signal;
a first processing unit configured to perform a frequency dispersion processing on the first signal;
a first output unit configured to output the first signal or the first signal on which the first processing unit performs the frequency dispersion processing;
a second input unit configured to receive a second signal generated through performing a predetermined image processing with an image processing unit on the first signal output from the first output unit;
a second processing unit configured to perform the frequency dispersion processing on the second signal; and
a second output unit configured to output one of the first signal and the second signal on which the frequency dispersion process is performed as an output signal.
