摘要： To facilitate determination of a black point on a display unit, a reference brightness region and a comparison brightness region are displayed on the display unit. The former emits at a reference brightness that is used as a reference for determining the black point. The reference brightness is set by inputting a predetermined input value to the display unit. The brightness on the comparison brightness region is compared with the reference brightness. The comparison brightness is changed by increasing and decreasing the input value to the display unit to obtain a critical input value representing the input value wherein an operator can first distinguish the comparison brightness region from the reference brightness region. The two regions are arranged so that the comparison brightness region which is, for example, a star mark is completely surrounded by the reference brightness region, or vice versa.

摘要： The standard brightness region is displayed with input values of zero. The comparison brightness region is displayed with an input value which is variable in the range of 0 to 255. The standard brightness and comparison brightness regions are displayed next to each other in the display. The input value is changed from zero. A first black point is determined as an input value which causes the comparison brightness region to first appear distinguishable from the black regions of the standard brightness regions. Then, the input value is changed from 255. A second black point is determined as an input value which causes the comparison brightness region to first appear indistinguishable from the black regions of the standard brightness regions. Then, a black point is calculated as an average of the first and second black points.

摘要： In S100, multilevel density data C, M, Y, and K for a subject pixel are read out from the data recording medium. Then, the total ink density ND is calculated in S110. It is judged whether or not the total ink density ND is higher than the predetermined limit value L1. When the total density ND is not higher than the value L1 (no in S120), the original density data C, M, Y, and K for the subject pixel are subjected to the binarization process in S140. When the total density ND is higher than the value L1 (yes in S120), on the other hand, the value of the multilevel data for each chromatic color component is reduced through an ink density reduction process in S130. The thus obtained reduced multilevel data C3, M3, and Y3 and the black multilevel data are subjected to the binarization process in S140.

摘要： The first time a print program is activated, monitor calibration for calculating display characteristic of a display is executed (S10). Then the results of the monitor calibration operation are registered along with the present date (S20). The monitor calibration results and print information are outputted to a color printer (S30). The next and further times that the print program is activated, the number of days passed since the monitor calibration operation was last performed is calculated based on the previously registered date and on the present date (S40). Whether the calculated number of days exceeds a predetermined number of days is determined (S50). If so, then the monitor calibration operation is again performed (S60) and the calibration results and date are updated accordingly (S70).

A weighting-curve storing portion stores weighting curves for each of lightness, chroma, and hue. A weighting-factor determining portion determines, based on the weighting curves, weighting factors for the values of lightness, chroma, and hue. A specific-color-index determining portion determines a specific color index by multiplying each of the weighting factors determined by the weighting-factor determining portion. An adjustment-amount determining portion determines an adjustment amount by multiplying, by the specific color index, the amount of change set by the change-amount setting portion, and determines adjusted values of lightness, chroma, and hue based on the adjustment amount. An adjusted-color-image obtaining portion obtains an adjusted color image based on the adjusted values.

摘要： According to an image processing method, an input value combination is received. The input value combination includes a plurality of input values for a plurality of primary colors and is indicative of image information. The received input value combination is converted into an output value combination that includes a plurality of output values for a plurality of components for printing, the plurality of components for printing including black, the output value for black being smaller than or equal to a value of an allowable black maximum. An image obtained by printing an output value combination, whose value for black being greater than zero (0) and smaller than or equal to the value of the allowable black maximum value, exhibits substantially the same gloss with another image obtained by printing an output value combination, whose output value for black being equal to zero (0).
