TL;DR: Key areas identified where improvements in color would provide immediate tangible benefits were those of digital microscopy, telemedicine, medical photography (particularly ophthalmic and dental photography), and display calibration.
Abstract: This article summarizes the consensus reached at the Summit on Color in Medical Imaging held at the Food and Drug Administration (FDA) on May 8–9, 2013, co-sponsored by the FDA and ICC (International Color Consortium). The purpose of the meeting was to gather information on how color is currently handled by medical imaging systems to identify areas where there is a need for improvement, to define objective requirements, and to facilitate consensus development of best practices. Participants were asked to identify areas of concern and unmet needs. This summary documents the topics that were discussed at the meeting and recommendations that were made by the participants. Key areas identified where improvements in color would provide immediate tangible benefits were those of digital microscopy, telemedicine, medical photography (particularly ophthalmic and dental photography), and display calibration. Work in these and other related areas has been started within several professional groups, including the creation of the ICC Medical Imaging Working Group.

TL;DR: In this paper, a two-dimensional monochrome bit face display with ND filters transmitting light to the m sub-pixels in the proportion of values, represented by percentage, of respective terms of a power series of 1 /2n (where n is an integer from 0 to m-1 ), or mask filters transmitted light in the same proportion are mounted on the m subspixels constituting each of the pixels, respectively.
Abstract: There is provided a two-dimensional monochrome bit face display having its luminance resolution equal to or higher than that of a CRT monitor. In a two-dimensional monochrome bit face display having its bit face in which each of pixels is constituted by m sub-pixels (where m is an integer equal to or greater than 3), ND filters transmitting light to the m sub-pixels in the proportion of values, represented by percentage, of respective terms of a power series of 1 /2n (where n is an integer from 0 to m-1 ) or in the proportion of approximate values thereof, or mask filters transmitting light in the same proportion are mounted on the m sub-pixels constituting each of the pixels, respectively. Alternatively, areas of the m sub-pixels are set in the same proportion. Luminance of each sub-pixel is electronically controlled to improve the luminance resolution of the bit face display.

TL;DR: In this article, a power supply device includes a current resonant circuit configured to drive a transformer and a switching element, connected to a primary side of the transformer, switching element being periodically repeatedly turned on and off, and a controller configured to control the switching element.
Abstract: Provided are a power supply device capable of supplying required power even during standby and an electrical apparatus. A power supply device includes a current resonant circuit configured to drive a transformer and a resonant circuit using a switching element, the resonant circuit being connected to a primary side of the transformer, the switching element being periodically repeatedly turned on and off, and a controller configured to control the switching element so that the switching element performs a continuous operation in which the switching element is turned on and off continuously repeatedly or an intermittent operation in which the switching element is turned on and off intermittently repeatedly, in accordance with an external signal indicating the continuous operation or the intermittent operation.

TL;DR: This paper proposes a novel blind deconvolution method to alternately estimate PSF and the latent image, and incorporates the gradient reliability map (R-map) that enables edge selection appropriate for PSF estimation processing.
Abstract: Image restoration which restores a clear image from a single blur image is a difficult problem of estimating two unknowns: a point spread function (PSF) and its ideal image. In this paper, we propose a novel blind deconvolution method to alternately estimate PSF and the latent image. And we incorporate the gradient reliability map (R-map) that enables edge selection appropriate for PSF estimation processing. This method improves restoration performance by excluding noise that adversely affects the estimation, and the experimental results show that robustness is improved in our proposed method.

TL;DR: In this article, a reflectance calculation unit is stored a parameter RGain for adjusting the amplitude of the reflectance component R. The image resynthesis unit also calculates a corrected image Tout from the corrected illumination light component L′ and the corrected reflectance R′, as well as from a formula Iout=exp(log L′+RGain(log I−log L).
Abstract: Improving the visibility of the dark portion and to prevent the degradation of image quality caused by excessive correction. A reflectance calculation unit is storing a parameter RGain for adjusting the amplitude of a reflectance component R. An illumination light correction unit generates a corrected illumination light component L1 from an illumination light component L and a formula L1=(log(LAmp*L+1))/(log(LAmp+1)). An image resynthesis unit obtains a corrected illumination light component L′ from L′=LGain*L1 +(1−LGain)*L. The image resynthesis unit also calculates a corrected image Tout from the corrected illumination light component L′ and the corrected reflectance R′, as well as from a formula Iout=exp(log L′+RGain(log I−log L)). The value of the corrected illumination light component (L′) is determined based on the ratio (LGain) at which the output value of the correction function (L1) and the original illumination light component (L) are combined.
