Abstract: An imaging system includes a lighting controller for independently controlling emission of illumination light to be emitted by a light source in: (i) a non-all-line exposure period, which contains a reading period in which electrical signals are sequentially read out on a horizontal-line basis from an image sensor for one frame or one field period, and in which at least one horizontal line of the horizontal lines for the one frame or the one field period is not exposed to light, and (ii) in an all-line exposure period, in which all of the horizontal lines for the one frame or the one field period are exposed to light.
