Abstract
An imaging device () includes an all-pixel readout imaging element () outputting a LONG signal and a SHORT signal in one field period for each pixel line, a mixing level calculator () calculating for each pixel line a mixing level at which the luminance level of the LONG signal is saturated, and an offset calculator () calculating for each pixel line an offset that raises the luminance level of the SHORT signal to the mixing level. Level mixing means () generates a level mixed signal for each pixel line so as to obtain a LONG signal when the luminance level is lower than the mixing level and obtain a SHORT signal with the offset added when the luminance level is higher than the mixing level. Consequently, an image having a wide dynamic range and a high resolution can be obtained and line-to-line luminance differences in the obtained image can be suppressed.
