摘要： In order to prepare tone characteristic data or calibration data based on measurements of tone levels of four colors by nine tones, the lowest tone level in measured only once using a single patch that is common to all the four colors. As a result, the entire operation time can be reduced by the time that is required to measure three more patches. If there is a considerable gap between the actually-measured output level and a predicted output level (S114:NO), then an error message is displayed (S115). Then, the measurements are performed once again. Therefore, wasteful operations will not be continued with the tone characteristic data in its mistaken form. Instead displaying the error message, the error-occurring output value can be replaced with a value that is determined by interpolating between non-error-occurring output values around the error-occurring output value.

摘要： A color conversion function is corrected in accordance with the input color data (Xin, Yin, Zin) of the original image. The original image is therefore converted into colors which are different from colors of the original image but which are appreciated by the user. One or more specific color is previously determined. The appropriate color value memory 40 stores appropriate output values (Xbesti, Ybesti, Zbesti) for the specific colors. The color value discrimination portion 20 judges whether or not the input color data (Xin, Yin, Zin) is the specific color. When the input color data (Xin, Yin, Zin) is judged as the specific color, the corrected characteristic value calculation portion 24 calculates a correction characteristic value (dXi, dYi, dZi) based on the input color data (Xin, Yin, Zin) and the appropriate calor value. The color-conversion characteristic value correction portion 26 corrects conversion data (A, B, C) stored in the color-conversion characteristic value memory 42 based on the corrected characteristic values (dXi, dYi, dZi). The color conversion portion 28 converts the input color data (Xin, Yin, Zin) based on the corrected conversion data (a, b, c) produced and stored in the corrected color-conversion characteristic value memory 50, thereby outputting desired corrected color data (Xout, Yout, Zout).

摘要： When the profile data outputted from the external CPU 4 is not consistent with the contents of the memories 40 and 46 (no in S3), data in the first conversion characteristic memory 40 is rewritten with the profile data in S4. In S5, several color signals are generated. Then, in S6, the first color conversion process is attained to convert the several color signals into first intermediate signals. The second color conversion process is attained in S7 to convert the first intermediate signals into the second intermediate signals based on a stored color conversion characteristic. Thus, the third color conversion characteristic is produced in S8. In S11, with using the thus produced third color conversion characteristic, the third color conversion process is attained to convert the actually-inputted color data into control signals.

摘要： In a color picture image recording apparatus using a photosensitive and pressure-sensitive recording sheet having on its surface pressure rupturable microcapsules each containing a photosensitive material and a chromogenic material selected from cyan, magenta and yellow, and a mechanical strength of the microcapsule varies when exposed, a color tone of a reproduced picture image can easily be adjusted by the provision of a filter unit. The filter unit is used in conjunction with a radiation unit which radiates onto the photosensitive and pressure-sensitive recording sheet a light carrying a color image of an original to form a latent image, and includes filters each selectively passing a light of a particular wavelength which causes to vary the mechanical strength of one of the cyan-, magneta-and yellow-containing microcapsules. Each of the filters is movably disposed on a light path so as to change its filtering characteristic, whereby when the photosensitive and pressure-sensitive recording sheet is pressure-developed, the color tone of the reproduced color image can be adjusted.

摘要： In a thermal fixing device for use in a recording apparatus, an image on a recording medium is thermally fixed while passing through a nip between a pair of rollers. In order to prevent the recording medium from being wound around one of the rollers disposed to contact with the image formed surface of the recording medium, a diameter of that roller is made smaller than a diameter of the remainder, whereby a resilient force of the recording medium produced when the latter is curved along the surface of the smaller diameter roller overcomes an adhesion force that the image formed surface of the recording medium adheres to the smaller diameter roller.

摘要： An image processing method determines a number of smoothing times Stime so that the number of times, at which the corrected tone values will be modified, increases as the amount of modification, by which the corrected tone values are required to be modified, increases; and modifies the corrected tone values by dividing the modification amount by the number of smoothing times Stime so that the actual printing characteristics R[i] predicted to be actually obtained approach the ideal characteristics T[i] in steps of the smoothing times Stime. Therefore, the image processing method can prevent an abrupt change in the characteristics of printed color density levels before and after the corrected tone values are modified, even when the modification amount of the corrected tone values is large.

摘要翻译： 图像处理方法确定平滑次数Stime的数量，使得校正的色调值将被修改的次数随着需要修改的校正色调值的修改量的增加而增加; 通过将修正量除以平滑次数Stime的数量来修正校正的色调值，使得预测实际获得的实际打印特性R [i]以平滑时间Stime为步长接近理想特性T [i]。 因此，即使校正色调值的修正量大，图像处理方法也可以防止修正色调值修正之前和之后的印刷色浓度特性的突然变化。

摘要： An image-processing system for printing an image based on original image data. The storing unit stores at least one look-up table in association with at least one printing condition. The at least one look-up table is used to convert a color value in original image data into a limited color value that limits a total quantity of ink to be used in printing. The detecting unit detects, as a printing condition, at least one of a type of color material and a type of recording medium which are used for printing operation. The converting unit converts the color value data into the limited color value by using a look-up table that is assigned with a printing condition corresponding to the detected printing condition.
