    摘要： An image forming apparatus that can change to desired conditions of a color stabilization control performed through a stabilization control means, so as to provide color stabilization suited to a wide range of users, to thereby accommodate the needs of a variety of users. Color information is read from a predetermined color material by a density sensor. Color stabilization control is carried out based on the color information read from toner patch images made during image formation (S15,S16). A mode in which the color stabilization control is carried out is designated according to externally input information (S12). The color stabilization control is carried out in the designated mode (S13).

    摘要： This invention provides a display apparatus, control method, and control program, which display hue differences and color difference values of respective patches as lists, and display the hue direction of the hue difference of each individual patch on a chromaticity diagram in an easy-to-understand manner. To accomplish this, a display method of this invention includes a specifying step of specifying a color determined by a hue difference calculated from first and second values associated with spectral reflectance characteristics, and a display step of displaying the color specified in the specifying step as a graphical object. The specified color is specified as a representative color that indicates a hue on a chromaticity diagram to which the hue difference biases.

    摘要： Color reproducibility needs to be evaluated in consideration of the influence of homogeneity in page image. Hence, a first chart is formed from an image of a uniform density of a region to be evaluated, and data associated with the spectral reflectances of plural points on the first chart are input. Based on the data obtained from the first chart, color differences between a predetermined point and other points on the first chart are calculated. When the calculated color differences fall within a permissible range of heterogeneity of colors in the region, a second chart is formed from an image corresponding to a color target, and data associated with the spectral reflectances of plural points on the second chart are input. Color differences are calculated from the data obtained from the second chart and data associated with the spectral reflectance of the color target.

    摘要： An image forming apparatus (100) includes an image forming unit (120, 121, 122, 123) configured to form a measurement image on a recording paper (110), a fixing unit (150, 160) configured to fix the measurement image onto the recording paper by heating, a measurement unit (200) configured to measure the measurement image fixed on the recording paper downstream of the fixing unit in a conveyance direction of the recording paper, and a correction unit (325) configured to correct a measurement value output from the measurement unit such that an effect of temperature of the recording paper is decreased when the measurement unit measures the measurement image. The correction unit is configured not to correct the measurement value in a case where density of the measurement image is measured by the measurement unit, and the correction unit is configured to correct the measurement value in a case where color of the measurement image is measured by the measurement unit.
