The present disclosure relates to a system for measuring a naked-eye stereoscopic image, a method and apparatus for processing an image and a display device. The system includes: a naked-eye stereoscopic display device, configured to display preset images in sequence; an image acquisition device, configured to obtain monochromatic images by capturing display contents of the naked-eye stereoscopic display device, and send the monochromatic images to a processor; and a processor, configured to acquire at least one preset crosstalk amount to each stereoscopic pixel of the naked-eye stereoscopic display device from each view point according to the monochromatic images, where each of the at least one preset crosstalk amount represents a proportion coefficient that measures how much a view from another view point affects a color value of a view from a target view point.
