Abstract
An image processing apparatus includes a determination unit configured to determine whether a repetitive object is appropriate for being measured for density correction, a decision unit configured to decide, from pages including the repetitive object determined as appropriate for being measured for the density correction, a plurality of measurement pages to be measured for the density correction and a measurement position in the measurement pages, a measurement unit configured to measure density of the measurement position in the printed measurement pages, and a density correction unit configured to perform the density correction according to the measured density in the measurement pages for a page different from the measurement pages.
Claims10
An image processing apparatus comprising:
- a printing unit configured to print a print job including a repetitive object, which is repeatedly used in a plurality of pages;
- a determination unit configured to determine whether the repetitive object is appropriate for being measured for density correction;
- a decision unit configured to decide, from pages including the repetitive object determined as appropriate for being measured for the density correction, a plurality of measurement pages to be measured for the density correction and a measurement position in the measurement pages;
- a measurement unit configured to measure density of the measurement position in the measurement pages printed by the printing unit;
- and
- a density correction unit configured to perform the density correction according to the measured density in the measurement pages for a page different from the measurement pages.
A method for controlling an image processing apparatus including a printing unit configured to print a print job including a repetitive object, which is repeatedly used in a plurality of pages, the method comprising:
- determining whether the repetitive object is a repetitive object appropriate for being measured for density correction;
- deciding a plurality of measurement pages to be measured for the density correction and a measurement position in the measurement pages, from pages including the repetitive object determined as appropriate for being measured for the density correction;
- measuring density of the measurement position in the measurement pages printed by the printing unit;
- and
- performing the density correction according to the measured density in the measurement pages for a page different from the measurement pages.
