An imaging system includes an images outputting an analog green signal, an analog blue signal, and an analog red signal in a predetermined progressive-scanning format. The analog green, blue, and red signals are converted into parallel-form digital green, blue, and red signals, respectively. A set of the parallel-form digital green, blue, and red signals is converted into a set of a parallel-form digital luminance signal, a first parallel-form digital color-difference signal, and a second parallel-form digital color-difference signal. A signal divider separates the parallel-form digital luminance signal into a first sub parallel-form digital luminance signal and a second sub parallel-form digital luminance signal. The first and second sub parallel-form digital luminance signals are converted into a serial-form digital luminance signal. The first and second parallel-form digital color-difference signals are converted into a serial-form digital color-difference signal. A first electric-to-optical converter converts the serial-form digital luminance signal into a first optical signal having a first predetermined wavelength. A second electric-to-optical converter converts the serial-form digital color-difference signal into a second optical signal having a second predetermined wavelength different from the first predetermined wavelength. An optical multiplexes multiplexes the first optical signal and the second optical signal into a multiplexed optical signal, and outputs the multiplexed optical signal to an optical transmission line.
