Abstract:
Provided is a MTF measuring method that is capable of estimating an accurate MTF curve in one measurement. The method is a MTF measuring method for measuring the MTF of a CIS that includes a CMOS sensor, and a lens that directs incident reflected light from a document via a contact glass to the CMOS sensor. A test chart is placed on the contact glass via a transparent plate having a thickness that varies at different locations in the sub scanning direction. Then, the CIS is caused to scan in the sub scanning direction, and in one scan, is caused to measure respective MTF at multiple measurement locations where the thickness of the transparent plate differs.

Claim (Index 4):
The MTF measuring method according to  claim 3 , wherein\n the maximum thickness of the transparent plate among thicknesses at multiple measurement locations is set to be larger than a value that is obtained by subtracting the thickness of the spacer that is mounted at the time of measurement and the thickness of the contact glass from the maximum value of the assumed distance between the photoelectric conversion elements and the lens.
