摘要： An image formation apparatus is equipped with a recording head having a plurality of recording elements for forming an image on a recording medium. A binarized image data storage unit stores binarized image data for on-off control of the recording elements of the recording head. A correction data storage unit stores density irregularity correction data for correcting irregularities in density which occur when the recording elements of the recording head are respectively driven to form the image for each of the recording elements. A density irregularity correction unit corrects, prior to the image formation, the binarized image data stored in the binarized image data storage unit on the basis of the density irregularity correction data stored in the correction data storage unit.

摘要： An image display processing apparatus receives input illuminant information relating to input illuminant illuminating object when photographing, input device information specifying input characteristic of a photographing device, and image signal. Spectral reflectance image signal of the object is obtained from the image signal, the input illuminant information, and the input device information. Rendering light is applied to the spectral reflectance image signal, and output to a display device. A spectrum of light emitted from a variable characteristic illumination device for illuminating a display viewing environment can be varied. Spectrum of observing illuminant illuminating the display viewing environment is measured by a spectrometer unit. A spectrum of the rendering light is determined to substantially match with a spectrum of the input illuminant. The spectrum of the light emitted from the variable characteristic illumination device may be adjusted to substantially match the spectra of both the rendering light and the observing illuminant.

摘要： A format storage unit stores a predetermined geometric property format. A chart data creating unit creates chart data based upon the geometric property format, and a printing unit creates a test chart by printing mark groups on a recording medium such as a paper sheet based upon the chart data. An image pickup unit outputs a chart image by scanning the test chart, and a mark center calculating unit calculates the center of each mark based upon the chart image. A fitting unit performs a fitting calculation comparing calculation results output from the mark center calculating unit and the chart based upon the geometric property format such that the squared difference therebetween becomes minimum for each mark position.
