An image scanning, displaying and lighting system for eliminating color differences is revealed. The system includes an image scanner, a display screen with a second emission spectrum and a lighting device with a third emission spectrum. The image scanner consists of an optoelectronic image capturing and forming system, a plurality of first light sources disposed around the optoelectronic image capturing and forming system and a control module. The first light sources have a first emission spectrum which is a white light composed of a plurality of wavebands with different peak wavelengths. The control module controls the optoelectronic image capturing and forming system to take monochrome images in different colors in time sequence. The second emission spectrum has the same characteristics as the first emission spectrum while the third emission spectrum has the same characteristics as the second emission spectrum.
