Abstract:
A multispectral image capturing apparatus has different spectral sensitivity characteristics of at least four bands. Three primary bands of the at least four bands have spectral sensitivity characteristics of standard RGB. At least one auxiliary band of the rest of the at least four bands excluding the three primary bands has a spectral sensitivity characteristic of a narrower bandwidth than bandwidths of the RGB.
Abstract:
A multiband camera control apparatus comprises a multiband camera section configured to be capable of capturing a plurality of color bands, a computer configured to control the multiband camera section, a user interface configured to transmit instruction information for the control from the user to the computer, and parameters configured to control the corresponding band in each of the plurality of bands. The user interface includes a switching instruction section configured to switch between the plurality of bands. The computer is configured to control the multiband camera section by using the parameter corresponding to the band selected according to the instruction to switch between the plurality of bands from the switching instruction section.

Abstract:
An image capturing apparatus includes a first image sensor unit, a second image sensor unit, and a spatial frequency reduction unit. The first image sensor unit is capable of subjecting an object image formed by an imaging lens to a photoelectric conversion to output a first image signal having a first resolution and constituted by a first number of colors. The second image sensor unit is capable of subjecting the object image formed by the imaging lens to a photoelectric conversion to output a second image signal having a second resolution that is lower than the first resolution and constituted by a second number of colors that is larger than the first number of colors. The spatial frequency reduction unit reduces a spatial frequency of the object image formed on a light receiving surface of the second image sensor unit by the imaging lens.
Abstract:
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.
Abstract:
An image display device which displays a multiband image acquired by a multiband camera capable of capturing two or more bands comprises a parameter input/output and image outputting screen configured to represent each band itself or an image of the band, a band-RGB conversion table configured to use for converting a band number into a color represented in the a parameter input/output and image outputting screen, and wavelength information converting unit configured to calculate the band itself or the color representing the image of the band from the band number by use of the band-RGB conversion table to output the band or the color to the a parameter input/output and image outputting screen.
Abstract:
A geometrical correcting method allowing geometrical correction to be performed simply, accurately and in short a time, even in a multi-projection system including a screen of complex shape and projectors complexly arranged, for significantly improving the maintenance efficiency. Test pattern images having feature points are projected by respective projectors, and captured and displayed on a monitor, approximate positions of the feature points are designated and input while referring to the displayed test pattern captured image, and the accurate positions of the feature points in the test pattern images are detected according to the approximate position information. An image correction data for aligning the images projected by the projectors is calculated from the detected positions based on the feature points, the coordinate information of the feature points in a predetermined test pattern image, and the coordinate position relationship between a separately predetermined contents image and the test pattern captured image.
Abstract:
A color reproduction system includes an image input apparatus configured to capture an image, a color correcting section configured to transform the colors of the image captured by the image input apparatus, and an image output apparatus configured to output by one of displaying and printing the image which is transformed the colors by the color correcting section. The color correcting section transforms the colors of the input image into those of an output image by using information on the lighting environment at the time of capturing the image, information on the lighting environment at the time of observing the image and information on the image input apparatus. The information on the lighting environment at the time of observing the image includes information on at least two lighting environments that are different from each other.
Abstract:
An image processing system is used for dentistry. Upon creating a false tooth of a patient (59), a plurality of illuminating light of LEDs with different wavelengths emit light and a photographing apparatus (1A) photographs a tooth portion of the patient (59), thereby obtaining image data. The image data is sent to a dentistry filing system (2A) serving as a processing apparatus, and color reproducing data is obtained by calculation. The color reproducing data is sent to a dentistry factory (55) via a public line. Data is searched from a database (56) for calculating a ceramic compounding ratio, compound data of the ceramic false tooth is obtained, matching the color of the tooth portion of the patient (59), and the false tooth approximate to the tooth color of the patient (59) is created.
