摘要： In an image display apparatus including a multi-electron beam source having a plurality of electron-emitting devices (51) wired in a matrix using a plurality of column wiring layers and a plurality of row wiring layers, and a plurality of phosphors which are excited to emit light upon irradiation of electron beams, a delta arrangement of phosphors is realized with the simple arrangement of the multi-electron beam source. The column and row wiring layers are straight layers, the plurality of phosphors (R, G, and B) are arranged in a delta arrangement, and the multi-electron beam source is adjusted such that a plurality of electron beams emitted therefrom reach the phosphors. For this reason, the directions of electrons emitted from the devices on an odd ((2p-1)th) row and an even (2pth) row along orbits are reversed.

摘要： This invention can suppress overshoot/undershoot, and can maintain the improvement effect of the leading edge of an edge portion. For this purpose, a second derivative signal generator (1) generates a second derivative signal (s5) on the basis of time-serially input three successive pixels. A second derivative signal suppression unit (2) generates a signal (s8) obtained by suppressing the second derivative signal, and a signal (s9) indicating the sign of the second derivative signal. The absolute values of the differences between the pixel of interest, and its neighboring pixels are computed, and a smaller one of the absolute values is selected as a signal (s14) by a minimum value selection circuit (18). By multiplying the obtained signals (s8, s9, s14) by a multiplier (19), an edge-emphasizing signal (s15) is generated. The edge-emphasizing signal (s15) is added to the signal of the pixel of interest by an adder (20), thus obtaining an edge-emphasized signal s16.

摘要： The present invention relates to an image display apparatus for forming an image with a plurality of luminescent spots to be precisely aligned in a matrix. For example, a spacer disposed between an electron source and a face plate causes luminescent spots on the face plate spaced unevenly. The luminescent spots spaced unevenly will produce a visual unevenness in luminance which deteriorates the quality of produced image. By modifying the quantity of light of luminescent spots spaced unevenly, the visual unevenness in luminance is compensated.
