摘要:
A color conversion processing execution portion 114 implements color conversion processing on an input image signal, and outputs a color conversion-processed display image signal to an image display unit. Color conversion characteristic information required for the color conversion processing performed by the color conversion processing execution portion 114 is gathered by a characteristic information gathering portion 106. A color conversion processing method selection portion 112 selects an optimum color conversion processing method from among a plurality of candidate color conversion processing methods that can be executed by the color conversion processing execution portion 114 on the basis of the input image signal and the input color conversion characteristic information. A display image signal caused as a result of the color conversion processing is output to a monitor display device 140.
摘要:
A video signal processing device which processes a video signal input into a display monitor inputs illumination profile information relating to an illumination spectral characteristic of a light source and monitor profile information relating to a display profile of the display monitor. A video signal conversion unit performs color conversion processing on the input video signal on the basis of the illumination profile information and monitor profile information, and outputs a video display signal to the display monitor. As a result, color correction is performed on a video image displayed on the display monitor.
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:
An optical system is presented that enables images of a wide range of natural subjects to be well reproduced with their colors, and provides an image pickup system including, at least, an image pickup optical system, an electronic image pickup device having three or more different spectral characteristics to obtain a color image, and a controller for implementing signal processing or image processing on the basis of an output from the electronic image pickup device. The optical element that takes part in determining the focal length in the image pickup system includes an optical element making use of a refraction phenomenon alone. The 400-nm wavelength input/output ratio is 10% or less with respect to an input-output ratio for a 400-nm to 800-nm wavelength at which an output signal strength ratio with respect to an input quantity of light is highest when the input quantity of light is defined by the quantity of a light beam emanating from the same object point and entering the image pickup optical system and the output signal strength is defined by the strength of a signal produced from the controller in response to the light beam.
