An object of the invention is to provide a method of correcting sensitivity and an imaging apparatus, by which shading correction can be performed with good accuracy even with a simple structure. A method of correcting sensitivity includes providing imaging elements each including a photosensitive section (15) which performs photoelectric conversion of incident light, an electric charge accumulation section (18) which accepts transfer of electric charge accumulated in the photosensitive section (15) and temporarily accumulates the electric charge, and an electric charge correction section (20) which estimates electric charge intruding into the electric charge accumulation section (18); receiving light from an object by the imaging elements (3) to accumulate electric charge; thereafter transferring electric charge accumulated in the photosensitive section (15) to the electric charge accumulation section (18); correcting a first amount of electric charge (p1) accumulated therein with a second amount of electric charge (p2) having intruded into the electric charge correction section (20) to produce a third amount of electric charge (p3); and sequentially outputting third amounts of electric charge (p3) as amounts of electric charge of the respective imaging elements (3), thereby removing shading.
