In an image display apparatus which has a multi-electron beam source in which a plurality of electron emission elements are connected in a matrix pattern using a plurality of data electrodes and a plurality of scanning electrodes, and a fluorescent screen having phosphors of three primary colors R, G, and B corresponding to the electron emission elements, natural white color emission is obtained while suppressing a decrease in G luminance, using, e.g., a checkerboard layout which has a G spatial resolution higher than the R or B spatial resolution and includes more G phosphors than the R or B phosphors. For this purpose, the scanning electrodes connected to the electron emission elements corresponding to the G phosphors are electrically independent from those connected to the electron emission elements corresponding to the R or B phosphors, signal components corresponding to the G phosphors and signal components corresponding to the R or B phosphors are extracted from an image signal for a 1-line period, and the scanning electrode connected to the electron emission elements corresponding to the G phosphors and those connected to the electron emission elements corresponding to the R or B phosphors are selected during successively the 1-line period.
