Abstract
An image pickup system includes a plurality of electron multiplication image pickup apparatuses; and a correction coefficient calculating device. The correction coefficient calculating device measures electron multiplication properties of image signals output from the electron multiplication image pickup apparatuses on a regular basis, calculates correction coefficients that are used to adjust the sensitivity of image signals from the electron multiplication apparatus, and sets the calculated correction coefficients in the electron multiplication image pickup apparatuses.
