Abstract: There is provided an imaging device including an imaging unit that performs photoelectric conversion with respect to object light and generates a video signal, a timing generating unit that instructs the imaging unit to generate the video signal at a predetermined imaging frame rate, a time code generating unit that generates a time code to be added to the video signal, and an output signal control unit that stores the video signal and the time code added to the video signal in a memory, reads a combination of the video signal and the time code stored in the memory at a second frame rate according to a transmission frame rate for when the video signal is transmitted to an external device, and outputs the combination.
