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.

A method for processing an image includes: determining a reduction ratio that falls within a predetermined range; generating reduced image data indicative of a reduced image based on original image data indicative of an original image by dimensionally reducing the size of the original image to the size of the reduced image by the determined reduction ratio, the reduced image data indicating density values of pixels contained in the reduced image; and emphasizing edges in the reduced image by amplifying a change in the density values of pixels belonging to the edges in the reduced image based on the density values of the pixels contained in the reduced image. The emphasizing edges includes: correcting the density values of the pixels in the reduced image data by using correction data; and modifying the correction data to be used for correction of the density values of the pixels in the reduced image data, the correction data being modified dependently on the reduction ratio, to thereby vary a level of amplification of the change in the density values dependently on the reduction ratio.

An image-processing method includes: subjecting original image data indicative of an original image to a selective noise reduction by reducing noise from pixel data that meets a prescribed condition among all the pixel data in the original image data; and performing a first calibration to calibrate contrast of a backlight region of the selectively-noise-reduced original image data to generate an output image by determining a first pixel component and a second pixel component for each pixel data in the selectively-noise-reduced image data, by increasing contrast of the second pixel component, and by recreating pixel data based on the first pixel component and the calibrated second pixel component.

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.

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.

A color-conversion-table creating method includes (a) defining a color gamut in a first color space defined for a first device, the color gamut having a surface, an internal space surrounded by the surface, surface grid points positioned on the surface, and internal grid points positioned in the internal space, and determining a correspondence relationship between the surface grid points in the first color space and parameters in a second color space defined for a second device, (b) determining, based on the correspondence relationship determined in step (a), a correspondence relationship between the internal grid points in the first color space and parameters in the second color space, and (c) creating a color conversion table indicative of a correspondence relationship between all grid points in the first color space and parameters in the second color space based on both the correspondence relationship determined in step (a) and the correspondence relationship determined in step (b).

Reciprocating cutting tools (1, 90, 100) may include a drive source (11) for reciprocally driving a blade (B). The drive source may also drive a blower (13) in order to generate an air stream. An air channel (50, 56, 50, 70, 85, 80) may guide the air stream to a position adjacent to the blade or a workpiece (W) that will be cut by the blade. Further, a chip collector nozzle (57) may draw or suction cutting chips away from the workpiece that has been cut by the blade.
