Abstract:
     An image display apparatus of this invention includes a neighborhood data integration section 20 which 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 adder 6 adds the integrated image data R22, G22, and B22 on the respective colors, a coefficient operation section 7 which multiplies an addition result by a predetermined coefficient according to a luminous intensity of the halation, an adder 8 which adds outputs R23, G23, and B23 obtained by inverting a sign of multiplication results to image data R14, G14, and B14 corresponding to the electron emitting device to be driven, respectively, and a comparator 11 which compares an addition result with zero in magnitude, and which outputs a driving signal R25 for the respective colors.
