Abstract
An image processing apparatus includes a calculator configured to calculate a first difference value between frames in terms of either one or both of a position and a direction of a direct light by comparing a current frame to at least one previous frame, and a determiner configured to determine that an indirect light of the current frame is to be sampled in response to the first difference value being greater than or equal to a threshold.
