<p>It has been reported that both luminance and melanopsin stimulation affect the discomfort glare. However, in previous studies, visual stimuli were only presented to a part of the field of view. In this study, we examined the effect of melanopsin on discomfort glare in a lighting environment and attempted to formulate a discomfort glare, including its application in designing interior lighting. A white interior apparatus with a multispectral light-emitting diode light source placed on the ceiling was used, and ten participants evaluated the glare levels under several conditions. Glare perception was evaluated using nine categories corresponding to unified glare rating (UGR) values. Eight conditions were prepared by combining correlated color temperatures (2700, 5000, and 8000 K) and melanopsin stimulation. The luminance conditions of the luminous part were set to approximately 18,000 and 45,000 cd/m<sup>2</sup>. We found that glare perception was affected by melanopsin stimulation when the correlated color temperature and luminance conditions were constant, but not by differences in the correlated color temperature conditions. Furthermore, we analyzed the results and derived an evaluation equation for discomfort glare as a function of melanopsin and S-cone stimulation added to the UGR parameters. The proposed equation enables the precise evaluation of discomfort glare in lighting environments.</p>

Surface color results from a reflected light bounced off a material, such as a paper. By contrast, self-luminous color results directly from an emitting light, such as a Liquid Crystal (LC) display. These are completely different mechanisms, and thus, surface color and self-luminous color cannot be matched even though both have identical tristimulus values. In fact, previous research has reported that metameric color matching fails among diverse media. However, the reason for this failure remains unclear. In the present study, we created isomeric color-matching pairs between self-luminous and surface colors by modulating the spectral distribution of the light for surface colors. Then, we experimentally verified whether such color matching can be performed. The results show that isomeric color matching between self-luminous and surface colors can be performed for all participants. However, metameric color matching fails for most participants, indicating that differences in the spectral distributions rather than the different color-generating mechanisms themselves are the reason for the color matching failure between different devices. We experimentally demonstrated that there is no essential problem in cross-media color matching by generating isomeric pairs. Our results can be considered to be of great significance not only for color science, but also for the color industry.

What we taste is affected by what we see, and that includes the colour, opacity, and shape of the food we consume. We report two experiments designed to investigate how the standard deviation (SD) of the luminance distribution of food images influences the perceived visual texture and the taste/flavour experience by using the latest Augmented Reality (AR) technology. We developed a novel AR system capable of modifying the luminance distribution of foods in real-time using dynamic image processing for simulating actual eating situations. Importantly, this form of dynamic image manipulation does not change the colour on the food (which has been studied extensively previously). Instead, the approach outlined here was used to change the SD of the luminance distribution of the food while keeping the chromaticity, the average luminance, and the skewness constant. We investigated the effects of changing the luminance SD distribution of Baumkuchen (a German baked cake) and tomato ketchup on visual perception, flavour expectations, and the ensuing taste experience. Participants looked at a piece of Baumkuchen (Experiment 1) or a spoonful of tomato ketchup (Experiment 2) having different luminance distributions and evaluated the taste on sampling the food. Manipulating the SD of the luminance distribution affected not only the expected taste/flavour of the food (e.g. expected moistness, wateriness and deliciousness), but also the actual taste properties on sampling the food itself. The novel food modification method and system outlined here can therefore potentially be used to control the taste/flavour of different foods crossmodally by means of modifying their appearance properties (specifically the SD of the luminance distribution while keeping other aspects of image statistics constant), and can do so in real time, without the need for food markers.

Visualization of Crossmodal Effects Induced by Vision

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Japan Oil Chemists' Society Single Work
<p>Food appearance is critical information for estimating edibility, freshness and softness of foods. We developed some image processing techniques to modify the food appearance naturally. The first method is Luminance Distribution Manipulation (LDM). We found that LDM can modify the moistness and softness of foods in appearance. The second method is Visual Texture Exchange (VTE). VTE enables us to change the visual texture of a food from the original surface to other actual one, e.g. from Tuna to Salmon, and from Black Coffee to Café Latte in real time. The third method is Gloss/Shade Filter Operation (GSFO) which can create any Oily/Dried and Burned/Raw foods from an original food image in appearance. By applying such image processing methods and Augmented Reality technology, we are investigating crossmodal effects of food appearance to the taste while keeping the ingredients intact, indicating that we can artificially control the taste by modifying food appearance with image processing. Finally, I will introduce a novel approach to reduce salt by modulating saltiness by changing food appearances with Augmented Reality. We quantified the salt reduction effect by converting the perceived responses to match the amount of salt.</p>
