Abstract
An image display apparatus of this invention includes a neighborhood data integration sectionwhich integrates image data on respective colors corresponding to electron emitting devices proximate to an electron emitting device to be driven, and corresponding to a phosphor contributing to a halation, an adderadds the integrated image data R, G, and Bon the respective colors, a coefficient operation sectionwhich multiplies an addition result by a predetermined coefficient according to a luminous intensity of the halation, an adderwhich adds outputs R, G, and Bobtained by inverting a sign of multiplication results to image data R, G, and Bcorresponding to the electron emitting device to be driven, respectively, and a comparatorwhich compares an addition result with zero in magnitude, and which outputs a driving signal Rfor the respective colors.
