Document Type and Number:
Japanese Patent JP5858765
Kind Code:
B2
Abstract:
An image processing apparatus includes an obtaining unit configured to obtain a gamma correction table used for image formation on non-reference paper using a correlation between a characteristic of reference paper and a characteristic of the non-reference paper and a gamma correction table obtained through calibration using the reference paper, a first reading unit configured to form a pattern on plain paper and read the formed pattern, a second reading unit configured to form a pattern on an image bearing member and read the formed pattern, a comparison unit configured to compare a value read by the first reading unit with a value ready by the second reading unit, and a correction unit configured to correct the characteristic indicating the correlation used for obtaining the gamma correction table for the non-reference paper by the obtaining unit when a difference of values compared by the comparison unit exceeds a first threshold.
