ABSTRACT:
An image display apparatus of this invention includes a neighborhood data integration section20which 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 adder6adds 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 comparator11which compares an addition result with zero in magnitude, and which outputs a driving signal (R25) for the respective colors.
