Abstract:
A method for correcting a quantity of light emitted from a light emitting element, in a case in which an image is scanned and recorded on a photosensitive material by controlling, based on digital image data, quantities of light beams emitted from light emitting portions which allows emission of light beams of three colors, light beams of at least one color being emitted from a plurality of light emitting elements, said method comprising the steps of:correcting a drive signal level of each of the light emitting elements for the same digital image data, causing respective groups of light emitting elements that emit light beams of the same color, of a light emitting portion including a plurality of light emitting elements, to have the same quantities of emitted light within; andsubsequently, correcting the drive signal level of each of the light emitting elements for predetermined digital image data, causing the ratio of the quantity of emitted light between the respective groups of the light emitting elements, which emit light beams of different colors, to be set at a predetermined value.
