Abstract
An image processing apparatus for generating a high dynamic range image using a plurality of images obtained by capturing images of a same object with different exposure values, has: an input unit for inputting a correctly exposed image generated with correct exposure and an incorrectly exposed image generated with exposure other than the correct exposure; a filter unit for performing low pass filter processing on the incorrectly exposed image; and a composition unit for generating a high dynamic range image by composing an output image of the filter unit with the correctly exposed image.
