摘要： An image-forming device forms an image having improving image quality by conveying a sheet in a nonuniform conveyance, and reduces a processing load required for calibrating a conveying length for the recording medium. In an image-forming device, a process for acquiring a theoretical conveying length for conveying a recording medium (S404) and for calibrating the theoretical conveying length (S409) is only executed for a large feed used to convey the recording medium a second conveying length greater than a first conveying length (S405: YES) and not for small feeds used to convey the recording medium the first conveying length (S405: NO). Since calibration is performed on the second conveying length, which is greater than the first conveying length, this method reduces a decline in precision for the conveying length of the recording medium, even when reducing the number of calibrations.

摘要： According to a hue conversion, hue angles of C, M, and Y are always set to hue angles HC, HM, and HY of C, M, and Y of a printer, hue angles of R and G are always set to hue angles HR and HG of R and G of a monitor, and the hue angle of B is always set to a value HB desired by a user. The gradation from black through a full color to white is made linear in each color of R, G, B, C, M, and Y according to the hue conversion. The user sets the hue angle HB for B. Therefore, the user can obtain blue color B which provides the user's favorite hue and gradation. Every hue can be reproduced excellently and gradations can be reproduced without color shifts.

摘要： An adjusting portion adjusts values of lightness, chroma, and hue. A change-amount setting portion sets an amount of change for each of lightness, chroma, and hue. 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： An image forming apparatus is disclosed in which a quantization is effected for a halftone color image decomposed into pixels, in which a comparison is made, for respective separate color-components of each pixel, between a tone level of each pixel and a threshold value, and in which the tone level of each pixel is quantized to produce a discrete value having n levels. With a neighboring pixel of the subject pixel containing a first color-component, and with the subject pixel containing a second color-component, a relationship between the tone level of the second color-component of the subject pixel and the threshold value is compensated, such that, as the tone level of the first color-component of the neighboring pixel increases, a probability of occurrence of a second color-component ink dot formed at the subject pixel and/or a volume of an ink used for the same dot at the subject pixel, decreases.

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.

摘要： During the process of creating a density adjustment table, when the average value avg for ink amounts of Ci(n), Mi(n), and Yi(n) is less than or equal to 2 at some density level indicated by positioning number n, a CPU sets a correction range of 1 to n, which includes the subject density level with positioning number n and gradation levels lower than the density level with positioning number n. The CPU 5 corrects the n-number of sets of ink amount data (Ci(n), Mi(n), Yi(n)) within the correction range of 1 to n, and converts each data set (Ci(n), Mi(n), Yi(n)) within the correction range into a corrected data set (Co(n), Mo(n), Yo(n)), wherein Co(n), Mo(n), and Yo(n) have the values equal to the average value avg of the original ink amounts Ci(n), Mi(n), and Yi(n).
