Zusammenfassung:	An image pickup apparatus of the present invention includes an image pickup element for imaging a subject, and an image forming section for forming image data based on image-pickup data acquired from the image pickup element. The image pickup apparatus has a first image-pickup mode of acquiring first image-pickup data in a non-emission state of light from an illuminating section to the subject, and a second image-pickup mode of acquiring second image-pickup data in an emission state of light from the illuminating section to the subject. The image forming section forms the image data by using, as a correction value for the second image-pickup data, multiplication data that is acquired by multiplying differential data calculated based on the first image-pickup data and the second image-pickup data by light-distribution correction data for smoothing the light distribution characteristic of the illuminating section.
