A white reference member is used to obtain white reference data. An image sensor scans the white reference member line by line to obtain a plurality of lines of white reference data. A skipping unit skips the white reference data with a predetermined skipping ratio to generate a skipped white reference data. A dust detecting unit detects a dust between the white reference member and the image sensor based on the skipped white reference data. |
