Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.

The image processor converts a number of frames of image data into an image electrical signal. The first electrical-optical converter converts the image electrical signal to an image optical signal. The optical signal transmission element transmits the image optical signal to the second electrical-optical converter. The second electrical-optical converter converts the image optical signal to the image electrical signal. The time controlling unit transmits the image electrical signal to the source driving units, and outputs a controlling electrical signal to the gate driving unit. The source driving units and the gate driving unit cooperatively display the frames of image data on the display panel sequentially.
