There is disclosed a method and an apparatus of correcting image picked up from a frame photographed on a photo filmstrip through a photographic device. An exposure correction amount is calculated by use of correction parameters predetermined with regard to decrease in illuminance on a focal plane of the taking lens with radial distance from an optical axis of the taking lens, and a curvature of the photo filmstrip relative to the focal plane. The exposure correction amount is calculated for a respective pixel of the picture with regard to a relative position of the respective pixel in the frame to an optical axis of a taking lens of the photographic device. The relative positions are defined on the assumption that the photo filmstrip is held flat in a focal plane of the taking lens with a center point of the frame located on the optical axis at the photography.
