Abstract:
1. An image processing apparatus capable of independently performing a density adjustment on a plurality of density areas, wherein the plurality of density areas is overlapped with an adjacent density area, the image processing apparatus comprising: an input unit configured to independently input an adjustment value to the plurality of density areas; a generation unit configured to generate a correction characteristic based on the adjustment values according to the plurality of density areas; a correction unit configured to correct the correction characteristic to monotonously increase an inversion section of the correction characteristic in a case where a change in a gradation is inversed in the generated correction characteristic, so that the inversion section of the correction characteristic is monotonously increased based on maximum, minimum, and middle points in the generated correction characteristic; and a density adjustment unit configured to perform density adjustment on image data based on the corrected correction characteristic.
