OPTICAL SCANNING HEAD, IMAGE PROCESSING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE RECORDING MEDIUM STORING LIGHT INTENSITY CORRECTION CONTROL PROGRAM

摘要

Provided is an optical scanning head including plural light-emitting element arrays that are arranged along a scanning direction, each of which includes plural light-emitting elements, a light-emitting control unit that outputs a light-emitting timing signal generated based on image information to each light-emitting element of the plural light-emitting element arrays to control light emission of the light-emitting element, a storage unit that is common to the plural light-emitting element arrays and stores a correction value of a light intensity variation due to an arrival time difference between the light-emitting timing signals to the plural light-emitting elements, and a correction unit that corrects the light-emitting timing signal based on the correction value.

1. An optical scanning head comprising:
a plurality of light-emitting element arrays that are arranged along a scanning direction, each of which includes a plurality of light-emitting elements; a light-emitting control unit that outputs a light-emitting timing signal generated based on image information to each light-emitting element of the plurality of light-emitting element arrays to control light emission of the light-emitting element, the light-emitting timing signal including a light-emitting start signal and a light-emitting end signal of the light-emitting element; a storage unit that is common to the plurality of light-emitting element arrays and stores a correction value of a light intensity variation due to an arrival time difference between the light-emitting timing signals to the plurality of light-emitting elements; and a correction unit that corrects the light-emitting timing signal based on the correction value and executes a correction for making earlier, to match the light-emitting element having the maximum light intensity in the plurality of light-emitting element arrays, an output timing of the light-emitting start signals of other light-emitting elements.
