An imaging apparatus includes: an illumination unit that emits illumination light； a light receiving unit having pixels arranged on horizontal lines to receive light from an object irradiated with the illumination light, and to perform photoelectric conversion on the received light to generate pixel signals； an imaging controller that controls the pixels to sequentially start exposure for each horizontal line, and to sequentially read the pixel signals from the pixels belonging to the horizontal lines after a lapse of an exposure period from start of exposure； an illumination controller that switches between illumination states in a reading period for sequentially reading the pixel signals for each horizontal line, and controls an amount of the illumination light such that an integrated value of the amount of the illumination light during one frame period immediately after switching of the illumination states is the same as that during next one frame period.
