Spectral sensitivity of CCD color filters is one of the most important factors that determine essential image quality of an electronic camera. such as color reproduction and noise. Therefore, it is highly important to appropriately evaluate and optimize the CCD color filter characteristics. This paper introduces a new method for two-dimensional visualization of a tradeoff between color and noise properties. It was proved that newly-developed 4-color-CCD camera has advantages against conventional filter sets.
Also, an extended-gamut color space is essential to accurately store colors that are out of sRGB-gamut, and sYCC color space was used here. The sYCC color space was compared with other extended-gamut color spaces, such as Adobe/RGB, with evaluation of the media gamut cover ratio and the quantization level interval.

This paper describes the trend of recent high quality imaging system of inkjet printers. The fashion of inkjet printing technology is multi-color printing to improve the color gamut rather than the reducing graininess using conventional low-density ink. From this time, the long image permanence will become important to preserve the appearance of picture.

For the faithful color reproduction, multiband cameras have been studied and developed. On the other hand, high dynamic range image acquisition is also strongly desired in many applications. We have proposed a method for expansion of dynamic range with six bands camera that is composed of high-sensitive three bands and low-sensitive three bands. In the method, each pixel is processed, depending on its intensity, using one of thee kinds of band selections, i.e., high-sensitive three bands only, low-sensitive three bands only, or six bands all. In this paper, more combinations in band selection were tested. It was confirmed from the experiments that better color reproduction, especially in dark area, can be achieved by introducing more combinations in band selection.

In this research, we propose a method to match the glossiness of the images on different devices. In a preliminary experiment, we investigate the color components that influence the perception of glossiness, such as hue, saturation, and lightness. Based on this investigation, we found that lightness has greater influence than other color components and used lightness as the parameter for the glossiness model. Therefore we could obtain the glossiness model with consideration of the object color variation. By using the proposed model, we can match the glossiness of the various images on the different devices.

We propose an adaptive gonio-photometric imaging method for 3-D object based on a multi-spectral camera system and a robot system. It is shown that the method can estimate the optimal lighting directions based on the 3-D shape and the roughness of surfaces adaptively. We found that the reflectance spectra properties can be acquired effectively by our proposed method. The lighting directions can be controlled by the robot system, MELFA A-2 (Mitsubishi), and the 3-D shape and the reflectance spectra properties can be acquired by the 3-D digitizer which we developed simultaneously. The 3-D digitizer, VIVlD910 (Minolta) equips with five band camera.

In our previous paper, we reported that the reflectance spectra of human skin can be represented approximately 99.5% by using three principal components. This analysis, however, is based on the average value of the reflectance spectra on large area of skin since the reflectance was measured by using spectroradiometer or spectrophotometer. The principal components of reflectance spectra have not been analyzed in a small skin area which can be taken by digital camera. In this paper, we estimate and analyze the reflectance spectra of human skin in small area taken by multi-band imaging system.

For exact color reproduction between printing matter and projected image, it is necessary to match the color on absolute XYZ color space. However, the color value of each pixel is affected by stray light from the surrounding pixels which is due to the multi-reflection of optical lens in projector. In this paper, we analyzed the influence of each color value between printing matter and projected image, and modeled the relationship. This model became possible to estimate the color change of projected image. Using this estimation, the color of image is corrected to match the printing matter. We demonstrate the proposed method for the print of Macbeth color checker and shows that the model is effective for color matching of projected images.

Preference of photographic print is governed by the surface quality, i.e. appearance of its glossy surface, in addition to image quality. In the previous report, I proposed two physical measures representing surface quality, i.e. the degree of spread and winding of a surface reflected image. In the present report, surface quality preference and dominant attributes for the preference were rated by subjective evaluations. The preference are governed by the following three attributes: “smoothness”, “undulation” and “density-dependent image height”. Since the score of the former two attributes could be calcutated by using the physical measures, the preference level could be predicted by using the physical measures and the attribute score of “density-dependent image height”.

In the current study, we used a halftone dot structure model to incorporate the effect of light scattering and then estimated the colorimetric characteristics of single-ink halftone print. Our model assumes that a halftone dot consists of two regions. One region is a central area of the dot that has the same thickness of ink-layer as that of the solid print, and is referred as “core”. The other region is the marginal area of the dot that has thinner ink-layer than that of the solid print, and is referred as “fringe”. Using the model, we calculated the chromaticity coordinate values for single-ink halftone ramps and then compared them with the measured values. Consequently, the model could describe the non-linear behavior of single-ink halftone prints as well as predict the reflectance spectra more precisely than the Murray-Davies model.

In the digital photography system, the tonal characteristics of the system is evaluated by Camera-Through Sensitometry: CTS as the traditional photography. The tonal characteristics of reproduction image on the CRT monitor shot by digital steel camera, DSC was directly measure by colorimetric analysis. The lightness data on the displayed softcopy image of lightness linear single color step charts showed linear relation with the input data level. The slope of those characteristics indicated the qualitative tone characteristics of DSC. That relation for the chromatic magenta color chart was more distinctive than that of achromatic black and white step chart. The slope was also closely related to the tonal characteristics of reproduced object image on the photo-prints shot by DSC and reproduced by digital color printers.

To investigate the potential clinical use of a newly developed flat-panel detector (FPD) system by comparing its characteristic curve, resolution properties, radiographic noise and detective quantum efficiency (DQE) with those of a current FPD system. A comparison of low contrast detectability of a contrast-detail (C-D) phantom between new and current FPD systems was also performed. Consequently, it is also indicated that the newly developed FPD system can reduce the dosage by approximately 44% while providing the comparable detectability.

We have developed a digital full-field phase contrast mammography (PCM) system. PCM system has several advantages comparing with current digital imaging system without PCM configuration, such as 1) improvement of structural depiction by phase contrast, 2) the highest image solution with 25 micron meters pixels, and 3) improvement of image quality performance due to the air gap effect and to its reduction of the magnified image to the object's actual size. We compared images from the PCM system with images from digital imaging system without PCM configuration in terms of physical characteristics, subjective evaluation of images of a custom-made phantom, and performance in clinical application. The PCM system proved superior to current digital imaging system without PCM configuration by all measures of evaluation.

In this paper, gonio reflection properties of paper sheets were estimated from the measurements with small number of geometries. The estimation was based on the modeling of gonio reflection properties by the linear combination of Torrance-Sparrow model and Lambertian reflection. The model showed good correspondences with the reflection properties of paper sheets in wide range of glossiness. For relatively rough papers, the estimation of gonio reflection properties were achieved only with four geometries at the equal precision in the case of 284 geometries. For papers of high glossiness, the precise sampling at specular geometries was required.

When an exposed photographic glass plate is immersed in a gold (I) thiocyanate complex solution for several hours, gold particles grow on a latent image speck and we get a image with purplish red unicolor image due to plasmon absorption of the particles. After calcining it at 480°C, gelatin layer is burned off and gold layer is left behind on the plate. The image composed of gold layer with purplish blue unicolor by transmitted light and with golden gloss by reflected light was observed.

As long as the color reappearance method of RGB or CMYK is used, tone jump is absolutely unavoidable. Additional fluctuation in similar colors of the color to be reproduced utilizing output resolution can contribute to increase of visual effects of resolutions and color reappearances. In addition, it's also effective to reappear by a certain aggregate using resolution. There are a good noise and a bad noise in expressions. Color reappearance capabilities can be improved enough using good noises except monitor devices with low output resolution, even for 8 bits.

プラチナプリントはアルコール添加により増感できる。シュウ酸鉄 (III) 塩水溶液に光照射すると、光還元されるため、紫外域のその吸収が減少する。この反応でシュウ酸鉄 (III) 塩がかなり消費された時点から380nm付近に吸収極大をもっ可視域にも広がるブロードなピークが成長してくる。アルコールを添加するとこのピーク発生が見られない。いくつかのアルコールで、増感を示すアルコール添加量と、このピーク発生を抑えられる最低のアルコール量が一致していることから、アルコールによる増感が380nm付近に吸収極大をもつ物質の発生を抑制することに起因していると考えられる。

* color space for illuminants D65 and C was calculated. Then the gamut was compared with optimal colors containing 0.56% surface reflection. It was observed that there were portions withthe color gamut of SOCS wider than the optimal color in the low lightness section. Since it is a blue region, the fluorescence agent may be contained in the paper. Also the gamut was compared with gamut of real surface colors calculated by Pointer. It was found that gamut of SOCS is slightly wider than Pointer's in low lightness, and slightly narrower at regions of red and green in high lightness.

Shapes of developed silver grains strongly affects covering power and color tone of silver images in photothermographic films which are produced with a water base emulsion coating technology. We have analysed the grain shapes, the covering power, and the color tone of the developed silver images by experiments using typical photothermographic films and by simulations using Mie's light scattering theory and mathematical models for optical density. We found that color deviations from neutral grey at higher density in the silver images were dependent on the differences of light extinction efficiency factors of silver grains in the wavelength range of the visible light.

The effects of intramolecular hydrogen bonding on the electron-transfer properties of a series of bisphenol derivatives as compared with those of monophenol derivatives in which a hydroxy group is replaced by a methoxy group have been investigated in relation with their photographic properties. The oxidation of bisphenol derivatives with one-electron oxidants occurs to give the radical cation, followed by the deprotonation to produce the phenoxyl radical. Both the radical cations and phenoxyl radicals have been detected by laser flash photolysis measurements. Rates of hydrogen-transfer reactions from a series of bisphenol derivatives to cumylperoxyl radicals have been determined by monitoring the decay of the ESR signal due to cumylperoxyl radical produced by photoirradiation of an oxygen-saturated propionitrile solution of cumene and di-
t-butylperoxide in the presence of bisphenol derivatives. The intramolecular hydrogen bonding plays an important role in determining the overall oxidation reactivity in the two-electron oxidation process by decreasing the one-electron oxidation potentials and also by facilitating the deprotonation step from the bisphenol radical cation to produce a phenoxyl radical.

Viscoelastic behavior of the blend system of gelatin and κ-carrageenan wa examined. From pH dependence of the viscosity and the experiments using phthalated gelatin, we have concluded that the increased viscosity of the blend solutions is caused by formation of a gelatin-carrageena complex through electrostatic interaction. The blend of gelatin and the jet-treated carrageenan exhibited little pH dependence of the viscosity. The jelling characteristic of the blend solutions was examined. Addition of the jet-treated carrageenan to gelatin showed no change in the setting point but the clearly increased elasticity of the gel.

A study was made on the mechanism of twin plane formation during the nucleation ofAgCl grains. Experimental condition was controlled to make the growth of the nuclei in the presence of KSCN free from dissociation and re-nucleation. The grains thus obtained had (111) faces on the surface and the number of twin planes in each grain was judged according to a conventional way on the basis of its shape. The dependence of the number of twin planes per grain on the probability of twin plain formation was in accordance with binominal distribution. Further, the number of the grains with parallel twin planes was about 1/7 of that of all the grains with multi twin planes. These results indicate that the formation of a twin plane took place on one of (111) planes on rounded corners of a cubic grain in a random order.

-5 molAu/molAg. The smallest gold sensitizing speck detected contains 3 gold atoms. This technique is applicable to silver chloride emulsion and spectrally sensitized emulsion.

It is reported that natural background radiation and X-ray radiation for the baggage check in an airport affect the photographic properties of silver halide imaging materials. Since the mechanism of latent image formation for these ionizing radiations has not yet been established precisely, it was investigated here for
60Co-γ ray and 80kVp X-ray with octahedral AgBr emulsions. As a result, the sensitivities for these ionizing radiations could be quantitatively predicted from the characteristic curve for visible-light.

Partial Amendment of Copyright Law passed through the Diet in December 1996.
Accordingly the said protective period was finally placed on an equal footing with that of general works only to fructify the long-cherished campaign of the photographic association concerned, which resulted in the 50-year protective period after authors death as well as that in Europe and America.

We are attempting to use photography for education of aesthetic sentiments, expression, communication, and visual literacy. We had an opportunity to realize as a class of 13 hours in a junior high school. In this paper we report the curriculum and the results.

Recently, the demand for global environmental conservation and decrease of CO
2 evolution require the development of “new imaging media” instead of paper. This is called “electronic paper”, and many candidates have been reported to realize this new media. In this paper, some recent aspects of electronic paper will be reviewed.
