JOURNAL FREE ACCESSThe basic space design for exhibition and lighting at Tokyo National Museum are oriented by the following factors: 1. Easy to see 2. Simple 3. Comfortable The lighting design is the conclusive factor and this text introduces the exhibitions such as Japanese Ukiyo-e print that require the illumination restriction for its assumed vulnurability to light.View full abstractDownload PDF (3417K) -

JOURNAL FREE ACCESSAdvantages of the K3 System, a pigment inkjet printer system that uses three levels of black inks, were investigated. It was found that by printing these black inks throughout a large area of the constructed output data, in contrast to existing printers using conventional coloring sets this system offers a level of dependency of light source (Metamerism), deviation of multiple printers, tonal gradation and lightfastness that satisfies the demands of professional photo users.View full abstractDownload PDF (928K) -

JOURNAL FREE ACCESSThe technical purpose of image permanence evaluations is to simulate the image deterioration which occurs in the environment where the images are actually kept, and to predict a lifetime for the image based on the causes of this deterioration. The simulated environment for the image permanence evaluation methods described here is an indoor environment in which people live and images are displayed or stored. I focus the test methods on indoor light stability, gas stability and dark stability of print images. Trend of indoor light stability test is operated by Xenon weathering test instrument using additive UV cut filter like SC-37 to simulate real spectral irradiance in the room. Many researchers consider ozone gas test is an important test method to evaluate gas stability of image materials especially for dye-based inkjet prints. Arrhenius evaluation method is still useful to estimate dark stability.View full abstractDownload PDF (649K) -

JOURNAL FREE ACCESSWe have proposed a new CMOS color image sensor to overcome the difficulties, which current CMOS and CCD image sensors are facing with in increasing sensitivity and improving the deterioration of image quality caused by moire and color shading. Our device features organic photoelectric conversion layers formed on a CMOS signal read-out circuit. The photoelectric conversion layer requires both high sensitivity and low noise. While the dark current in the organic photoelectric conversion layer is the cause for the noise, it has not yet been suppressed well under working condition with appropriate applied voltage. In this paper, we adopted a technique to introduce charge-blocking layers between an organic photoelectric conversion layer and the two electrodes, and investigated the relationship between the dark current and the physical properties of the materials for the charge-blocking layers. We produced a trial product of the proposed image sensor with the adopted technique. We could confirm significant improvement in the image quality of the pictures taken by the trial product owing to the suppresion of the dark current and noise caused by the adopted technique.View full abstractDownload PDF (6545K) -

JOURNAL FREE ACCESSIt has recently been reported that the title compound exhibits an intense, sharp absorption band typical of the J-aggregate when the thickness of evaporated films is increased. We have replicated the J-band using a detector of the integrating sphere, with special attention to the emissive property of the compound. The use of the integrating sphere allowed us to measure the fraction of the emission component as a function of “sample/detector” distance. As a result, the “J-band” is found to be an artifact that arises when the evaporated film is abnormally thick (i.e. weak transmission) and when the emission intensity due to the incident light is comparable with that of the transmission. In addition, the “J-band” disappears as the emission component increases. This is obviously ascribed to an experimental error in optical measurements.View full abstractDownload PDF (910K) -

JOURNAL FREE ACCESSTone of the gold-layer photograph which made images with gold layer using silver salt photographic materials and the gold deposition development was studied. Because the gold-layer absorbs light, it becomes a negative image by transmitted light, while it is reversed out for the direct positive image by reflected light because the gold-layer at the high exposure area reflects light strongly. Both the negative image and the positive image appear on the same photograph. The tone reproduction of those negative and positive images was examined. Due to the uniform reflection of gold-layer at highly exposed areas, the tone at the highlight area got identified, while the transmitted density for the same area increased with exposure, and a contrasty image was formed.View full abstractDownload PDF (4759K) -

JOURNAL FREE ACCESSThis research investigated the effects that image quality exerts on how the personality of the subject in a photograph is estimated. We changed the image quality of photographs of the same subjects, and assessed their personalities using th SD method. The results of our investigations revealed that three factors emerge in the perception of personalities. The fact that image quality also exerts an influence on the impression created of the subject was also confirmed. A comparison between photographs of a male and a female revealed the interesting result that while brightness and contrast have similar effects on both, sharpness exerts varying influences.View full abstractDownload PDF (1427K) -

JOURNAL FREE ACCESSWe show that a ZnO membrane containing sub-micron structure such as solid rods and hollow tubes can be formed chemically on the polymer template substrate from an aqueous solution at 333 K. This advanced template method was entailed by immobilization of Pd catalyst on the polymer template and optimization of the deposition condition. The dimension of the obtained ZnO rod, the length and the outer diameter are 9 μm and 800 nm, respectively. Therefore, the aspect ratio is 11. 25: 1. A typical electric resistivity of the ZnO membrane was 22.4 Ωcm at room temperature.View full abstractDownload PDF (1299K)
