Abstract:
1. An apparatus for forming an image, comprising: an input device inputting image data; a lightness setting device that receives a lightness setting value selected by a user; a first corrector that corrects the inputted image data according to a first correction characteristic, wherein the first corrector operates in a first color space defined by additive color components; a first characteristic modifier that modifies the first correction characteristic from a first standard correction characteristic if the lightness setting value received by the lightness setting device is in a first range, and that does not modify the first correction characteristic from the first standard correction characteristic if the lightness setting value received by the lightness setting device is out of the first range, wherein the first corrector corrects the inputted image data according to the first correction characteristic irrespective of whether the first correction characteristic is modified or not; an image processor that processes the corrected inputted image data, into processed image data; a second corrector that corrects the processed image data according to a second correction characteristic, wherein the second corrector operates in a second color space defined by subtractive color components; a second characteristic modifier that modifies the second correction characteristic from a second standard correction characteristic if the lightness setting value received by the lightness setting device is in a second range different from the first range, and that does not modify the second correction characteristic from the second standard correction characteristic if the lightness setting value received by the lightness setting device is out of the second range, wherein the second corrector corrects the processed image data according to the second correction characteristic irrespective of whether the second correction characteristic is modified or not; and an image forming device that forms the image on a recording medium, based on the processed image data corrected by the second corrector, wherein the first range and the second range do not substantially overlap.
