    摘要: A monitor calibration method for determining the black point of a monitor display, wherein a solid black display area and a gray display area are displayed on a monitor screen in the form of stripes, for example, so that each display area is sandwiched by the other type of display area. Then, while the brightness of the gray display area is gradually changed, the user signals OK using a mouse device at the point in time that the viewer determines a difference between the two display areas. The input value of the gray display area at that time is fixed and saved as the black point. By arranging the display areas in alternating stripes, even a subtle difference in the two display areas is visually striking. Hence, a very accurate black point can be determined.

    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).

    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: An inkjet recording device records images by forming dots on a recording medium with droplet modulating method. The inkjet recording device includes a recording unit, a multilevel-data creating portion, and a dot-layout-data creating portion. The recording unit ejects ink droplets for forming dots at corresponding pixel positions. The recording unit is capable of changing a volume of each ink droplet to form dots with different sizes. The multilevel-data creating portion creates multilevel data based on image data. The multilevel data includes a dot size for each dot. The dot-layout-data creating portion creating dot layout data based on the multilevel data, so as to prevent the recording unit from forming dots having the same size continuously by greater than or equal to a predetermined number. The recording unit performs recording operation based on the dot layout data.

    摘要: In an image-forming method, a device reads line data L for one line and determines whether the resolution of the line data L in the main scanning direction is greater than or equal to a threshold th. If the resolution is greater than or equal to the threshold th, then a multiple line process is performed on the line data L to divide this data into two sets of partial line data L1 and L2. The partial line data L1 and L2 are used to form two lines at locations shifted from each other in the sub-scanning direction. However, if the resolution of the line data L is smaller than the threshold th, then a single line process is performed to divide the line data L into two segments Q1 and Q2. The segments Q1 and Q2 of the line data L are used to form a single line at the same location in the sub-scanning direction by printing the segment Q1 in the first main scanning operation and by printing the segment Q2 in the second main scanning operation.
