A color chart processing apparatus includes a spectrum calculating unit for receiving information regarding a spectral reflection factor of each color contained in a predetermined color chart and information regarding determination illumination light, and determining a spectrum of the color contained in the predetermined color chart under the determination illumination light by calculating the received information, and a determination information output unit for receiving a color signal of a subject, determining which color of the predetermined color chart closest matches the color signal of the subject by comparing the spectrum of each color determined by the spectrum calculating unit with the color signal of the subject, and outputting information identifying the resulting determination color.
摘要:
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.

When an image of a certain band in a multiband image obtained by a multiband camera capable of capturing at least two bands is displayed with a computer and at least one pixel is specified on the image, a spectrum computing section estimates a spectrum from the signal value of at least one pixel specified in the multiband image and displays the spectrum on a spectrum output screen.

An image display apparatus is provided which includes a screen and a plurality of projectors which respectively project images relating to a same object so that the images are superimposed on each other on the screen. One of the plurality of projectors is arranged spatially in substantially a plane symmetric relationship with another of the plurality of projectors so that the images are projected at projectors angles onto the screen to be substantially in alignment on the screen.

An image processing system includes a photographing apparatus (1) and a processing apparatus (2). The photographing apparatus (1) includes six LEDs (6a to 6f) for emitting light with characteristics of spectroscopic distributions varied in a visible light area, a monochrome-type CCD (8) which picks-up a subject image that is illuminated by the LEDs (6a to 6f) and is formed by an image pick-up optical system (7) and which outputs an image signal, and a CPU (18) which sequentially lights-on the LEDs (6a to 6f) upon an instruction for photographing a subject spectroscopic image being input from an operating switch (14), picks-up the image by the CCD (8), and thus controls the operation for capturing 6-primary-color subject spectroscopic images. The processing apparatus (2) includes a calculating device (21) which captures the 6-primary-color subject spectroscopic images photographed by the photographing apparatus (1) to create a display signal for color reproduction at the high fidelity level, and a display (22) which displays the display signal created by the calculating device (21).

An image recording device comprises: a first and second recording heads (11, 12) formed of recording elements cyclically arrayed, which are continuously arrayed with an overlapped region; image data distributing means (2) for distributing image data to these recording heads (11, 12); image data distribution region variation means (3) for setting an image data distribution region where the image data of each pixel is distributed to both the recording heads (11, 12) by the image data distributing means 2; correction parameter storage means (5) for storing a correction parameter for correcting the difference in the image density properties between the image data distribution region and the other region due to phase difference between the recording heads (11, 12); and image data correcting means (4) for correcting the image data in the image data distribution region based upon the correction parameter.
摘要:
In a color reproduction device, an input profile that is referenced in converting an input image from an image input device into a device-independent color image is created based on image input device information, shooting- and observation-time lighting data, and subject data, allowing accurate conversion of the input image to the device-independent color image. In reproducing the image by an image output device, the spectral reflectance of the subject itself is calculated from image input device information and shooting-time lighting data, thereby reducing the effect of the shooting-time lighting. The colors of the subject under observation lighting are calculated from observation-time lighting data. A color reproduced image is estimated accurately on the basis of the subject data even if the input image has little information.

A printer apparatus comprises a head having k (number) printing elements for printing an image data. A printing element selecting section selects a printing element driven at the time of printing among the k printing elements of the head. An image correcting section is a section for correcting the image data previous to the printing of the image data using the head, and comprises a correction data memorizing section for memorizing a correction data for a certain single tone among n (number) tones that the image data has for each of the printing elements, a tone detecting section for detecting the tone of the image data corresponding to each of the selected printing elements of the head, and a correction data generating section for generating a correction data for each of the selected printing elements, corresponding to the tone detected by the tone detecting section, by using the correction data memorized in the correction data memorizing section.
