1. An image capture device comprising: an image capture unit that performs an image capture and acquiring image capture data; an exposure value setting unit that sets an exposure value based on a luminance value of the image capture data acquired by the image capture unit; a comparison unit that compares the exposure value set by the exposure value setting unit to a preset value; an image capture control unit that directs the image capture unit to perform image captures a plurality of times and acquire a plurality of image capture data, in a case where, according to a result of the comparison by the comparison unit, the exposure value is equal to or less than the preset value; and an image data creation unit that performs a pixel additive synthesis for the plurality of image capture data acquired by the direction of the image capture control unit and creates image data.
