An image displaying apparatus, comprises: a plural number of electron sources, being disposed in matrix-like manner, each for emitting electrons therefrom; a driver for producing drive voltage for driving the electron sources upon basis of a video signal, to be supplied to the electron sources; and a correct circuit for correcting the video signal, wherein the correct circuit determines a predetermined number of correction points in horizontal and vertical directions, for the plural number of electron sources disposed in the matrix-like manner, corrects the video signal to the electron source corresponding to the correction point upon basis of a first correction value, which is determined in advance, and corrects the video signal corresponding to the electron source located between the correction points, upon basis of a second correction value, which is obtained through an interpolation calculation with using said first correction values, which are determined at each of the correction points, thereby correcting or compensating the unevenness in brightness, with using a small number of correction values therein.
