Imaging device

An imaging device comprising:

• a light modulation element that has a plurality of segments and has a light transmittance which varies between a high transmittance and a low transmittance for each segment;
• an imaging element into which light is incident through the light modulation element and in which a plurality of pixels is disposed in each segment;
• a number of high luminance pixels calculation section that calculates the number of high luminance pixels which have luminance values equal to or greater than a first luminance value for each segment, on the basis of a captured image signal which is obtained by the imaging element while the transmittances of all the segments are the same;
• a control section that controls the light modulation element such that the segments each having a number of high luminance pixels equal to or greater than a first number of pixels are set at the low transmittance and the other segments are set at the high transmittance;
• a low luminance pixel specifying section that specifies low luminance pixels having luminance values equal to or less than a second luminance value in the segments which are set at the low transmittance;
• and
• a gain correction section that performs gain correction on pixel signal values of the low luminance pixels, with a gain value corresponding to a ratio of the high transmittance to the low transmittance.
