An image exposure system for printing an image, comprised of pixels, on photosensitive media based on image data, includes an exposure unit for converting the image data into a light signal for exposure of each of the pixels, a measuring device and a compensator used to correct exposure levels. The exposure unit has light output elements for outputting the light signal for respective ones of the pixels onto the photosensitive media to effect exposure of the image on the photosensitive media. The measuring device is for measuring a density of each of the pixels of the image on the photosensitive media produced by exposing the photosensitive media with reference image data as the image data. The compensator corrects exposure levels of the pixels based on density data obtained by the measuring device, using the density data of a darkest one of the pixels as a reference to reduce differences between the exposure levels produced by respective ones of the output elements caused by changes in output characteristics of the exposure unit. The construction of the exposure system provides for compensation of changes in the light output elements without increasing the size of the exposure unit.
