`(57) Abstract: Provided in the present invention is an image pickup ap-
`paratus that is equipped with an image pickup element for picking up an
`image of a subject, and an image forming unit for forming an image data
`on the basis of the image-pickup data Obtained from the image pickup ele-
`ment, and that has a first image-pickup mode in which first image-pickup
`data is Obtained in a state wherein light from an irradiation unit is not irra-
`diated upon the subject, and a second image-pickup mode in which
`second image-pickup data is obtained in a state wherein light from the ir-
`radiation unit is irradiated upon the subject. Further, the image forming
`unit is configured such that image data is formed using multiplication
`data, which is Obtained as a result of multiplying difference data, calcu-
`lated on the basis of the difference between the first image-pickup data
`and the second image-pickup data, and light-distribution correction data
`for smoothing the light distribution characteristic Of the irradiation unit,
`as a correction value for the second image-pickup data.
