Rolling shutter imaging device and endoscope apparatus including the same

A wide dimming dynamic range and high dimming resolution are obtained without causing a variation in the amount of received light due to pulse illumination light in each line of an imaging element. An imaging device includes a light source emitting light by pulse driving, a light source control unit controlling the amount of emitted light by performing pulse modulation driving of the light source, and an imaging unit including an imaging element, in which a plurality of pixels are arrayed in a horizontal and vertical direction, and performs imaging by driving the imaging element using a rolling shutter method. The light source control unit performs pulse driving of the light source at a timing synchronized with a timing pulse signal having, as a period, 1/p (p is an integer of 1 or more) of the exposure start timing interval when driving the imaging element using the rolling shutter method.
