Abstract
An imaging apparatus according to an embodiment includes a first light source which emits first light, a second light source which emits second light, an imaging sensor, and control circuitry. The image sensor includes a plurality of pixels to receive light from an object, reads an electric signal generated by the pixel with a rolling shutter method, and outputs the electric signal for each frame. The control circuitry causes the first light source to be turned on M (M is an integer equal to or less than N) times in N frames in synchronization with a first period based on a blanking period of the frame, and causes the second light source to be turned on by selectively using multiple lighting patterns in which lighting timing is set in synchronization with the first period and a total lighting period in the N frames is different.
