Abstract:
1. An imaging device comprising: an all-pixel readout imaging unit outputting two types of signals, a LONG signal and a SHORT signal, for each pixel line in a predetermined field period, said LONG signal being a long-exposure-time video signal and said SHORT signal being a short-exposure-time video signal; a mixing level calculator calculating, for said each pixel line, a mixing level at which a luminance level of said LONG signal is saturated; an offset calculator calculating, for said each pixel line, an offset that raises a luminance level of said SHORT signal to said mixing level; and a level mixer generating a level mixed signal for said each pixel line so as to obtain said LONG signal when the luminance level of the long-exposure-time video signal is lower than said mixing level and obtain said SHORT signal with said offset added when the luminance level of the long-exposure-time video signal is higher than said mixing level.
