METHOD AND DEVICE FOR CALIBRATING AN IMAGING APPARATUS HAVING MULTIPLE IMAGING OUTPUTS |
摘要 |
An improved method and apparatus for calibrating an imaging system having multiple imaging outputs such as a plurality of laser diodes. Calibration is achieved by driving each imaging output to form a test pattern on an imaging element, each test pattern having one or more image regions and each image region having a target optical property such as a target optical density. Next, an optical property, such as optical density, is measured for each image region. A response curve is generated for each set of image regions having substantially equal target optical properties. The imaging outputs are adjusted by reducing a difference between the measured optical property and the generated response curve, thereby reducing optical variations between regions that are imaged by the multiple imaging outputs.
