Abstract
Disclosed is an image processing apparatus capable of effectively correcting color crosstalk in moving image capturing by a simple method, and a control method thereof. When the aperture value changes, the current white balance coefficient is corrected, calculating an estimated white balance coefficient corresponding to the changed aperture value. Re-obtainment of a white balance coefficient starts using a frame image captured at the changed aperture value. During a period required to obtain again a white balance coefficient, the estimated white balance coefficient is applied to a frame image to undergo white balance processing.
