An image correction apparatus for the printing apparatus includes a printer, reader, correction coefficient calculation unit, image correction unit, and smoothing unit. The printer prints a predetermined correction chart so as to ensure a partially overlapping region in a region printed by main scanning of the print heads. The reader reads a printed image of the predetermined correction chart printed by the printer. The correction coefficient calculation unit calculates a predetermined correction coefficient on the basis of the printed image of the predetermined correction chart read by the reader. The image correction unit performs predetermined image correction in advance for printing image signals input to the print heads, on the basis of the predetermined correction coefficient calculated by the correction coefficient calculation unit. The smoothing unit performs, for the printing image signals input to the print heads, signal processing for smoothing in advance a density value at a portion corresponding to the overlapping region with respect to a density value at a portion other than the portion corresponding to the overlapping region.

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.
