*1 Gain correction: The gain ratio of the analog video signal output from CCD is adjusted to be a fixed value.
*2 Move shading correction: Even when the document density is constant, the CCD output level does not become constant due to the following reasons.
- Variation in pixels for CCD
- Difference of the transmitted light intensity between the center and the surrounding of the lens
- Difference of the light intensity between the center and the surrounding of the document lamp
- Deterioration of the document lamp
Shading correction is performed to correct unevenness of the CCD output level.
