Provided is a method for adjusting an image pickup device, wherein a position of an image pickup element is set to an initial position, a uniform luminance surface is picked up, a luminance distribution on an image pickup surface is calculated, whether data of the luminance distribution on the four corners of the image pickup surface substantially agree with each other or not is judged, and such operations are repeated until the data substantially agree with each other by moving the position of the image pickup element by a predetermined value. By using the position of the image pickup element obtained when the data substantially agree with each other as information of the center position, the center position of the image pickup element can be adjusted in a short time and an image having a natural luminance distribution can be obtained.
