Abstract
A pixel value is adjusted to satisfy an exposure condition using a ratio (EV ratio) of exposure amounts of images taken without illumination light and with illumination light. When the pixel value of one of two images is modified, a subtraction process is performed on the pixel values of these two images. By finding a difference between two images that satisfy the exposure condition for pickup, the effect of a shadow or the like due to an interior lamp can be eliminated. Finally, the subtraction result is adjusted. As a result, an image processing apparatus, image pickup apparatus, and image processing method can be provided capable of eliminating the effect of a shadow or the like due to an outside light caused to the taken image.
