1. An image capturing apparatus, comprising:
a rolling shutter image sensor;
a wheel located on a photosensitive side of the rolling shutter image sensor, wherein a light shielding part and a light transmission part are disposed on the wheel, the light shielding part is configured to block light, and the light transmission part is configured to transmit light;
a driving apparatus that is connected to the wheel, and is configured to drive the wheel to rotate, wherein
the rolling shutter image sensor comprises a plurality of rows of photosensitive units, and the plurality of rows of photosensitive units are configured to: receive light transmitted by the light transmission part, and convert a light signal into an electrical signal through optical-to-electrical conversion; and
an image processing apparatus configured to obtain an exposure time of a first-row photosensitive unit based on an exposure time of a third-row photosensitive unit, a transition status time, a row in which the first-row photosensitive unit is located, and a quantity of rows of the plurality of rows of photosensitive units; and perform brightness balancing on a pixel corresponding to the first-row photosensitive unit.
