20090021739 | IMAGING APPARATUS - An imaging apparatus includes a light source unit that selectively outputs white light and light in a different wavelength band to an observation target, an imaging unit including an imaging device, and a spectral image formation circuit that generates a spectral image signal for a specified wavelength by an operation using an image signal based on an output from the imaging unit and predetermined matrix data. The imaging unit selectively obtains an image of the observation target for each of first, second and third light components in a visible light region and an image for each of at least fourth and fifth light components in a near-infrared region. Further, the imaging unit includes first spectral devices that make only the first and fourth light components enter first pixels of the imaging device and second spectral devices that make only the second and fifth light components enter second pixels thereof. | 01-22-2009 |
20090097028 | Color Measurement Systems And Methods Addressing Effects of Ultra-Violet Light - Systems and methods are provided to address the potential impact of lighting conditions/light sources on color measurement and/or color matching, particularly as such light variation relates to UV levels. The systems and methods generally include a UV visualizer that is adapted to establish and/or compare UV profiles for individual substrates/samples, e.g., print materials, under various illuminating conditions. According to the disclosure, it is possible to determine both (i) how a sample (e.g., a printing material) responds to UV light, and (ii) the amount of UV light under which the sample is viewed without the need to measure the excitation pattern of the sample/paper or the spectra of the illuminating light. In this way, a true color reading and/or color match may be achieved. Color corrections may be implemented that necessarily address the level of color brightener, if any, in the substrate or paper to be printed upon. | 04-16-2009 |

20130201482 | OPTICAL IMAGING SYSTEM WITH MULTIPLE IMAGING CHANNEL OPTICAL SENSING - An optical imaging system for use with an infusion tube including: at least one light source for emitting at least two of first, second, or third spectrums of light; an optics system including a single lens for receiving and transmitting at least two of the first spectrum light transmitted through a first portion of the chamber, the second spectrum light transmitted through a second portion of the chamber, or the third spectrum light transmitted through a third portion of the chamber. The system includes a sensor receiving the at least two of the spectrums from the lens and generating and transmitting data characterizing the at least two of the spectrums. The system includes a memory element storing computer readable instructions and a processor to execute the instructions to generate, using the data, at least two of first, second, or third images of the first, second, and third portions, respectively. | 08-08-2013 |
20140176950 | ARTIFICIAL RETINA DEVICE - The present technology provides a color-sensing device that includes an electrically-conductive substrate and a bulk heterojunction (BHJ) polymer layer formed on the substrate. The color-sensing device is configured to detect a first color of two colors and produce a first electrical signal that includes a first current response indicating detection of the first color. The color-sensing device is further configured to detect a second color of the two colors and produce a second electrical signal that includes a second current response indicating detection of the second color. | 06-26-2014 |
20160033332 | APPARATUS AND METHODS FOR EXTRACTING TOPOGRAPHIC INFORMATION FROM INSPECTED OBJECTS - Systems and methods for extracting topographic information from inspected objects to identify defects in the inspected objects. A part to be inspected is illuminated with at least two different colors emitted from an illuminator providing a gradient of light consisting of the at least two different colors. A single color image of the illuminated part to be inspected is acquired, providing a color-coded topographic mapping of the part to be inspected due, at least in part, to the gradient of light. Topographic monochrome views of the part to be inspected may be generated from the single color image. Each view of the topographic monochrome views may enhance a different type of feature or defect present in the part to be inspected which can be analyzed and detected. | 02-04-2016 |
20160033405 | Detecting Device and Detecting Method of a Transparent Display Panel - The present disclosure relates to a detecting device and a detecting method of a transparent display panel. The method comprises: providing a reference pattern sheet having n pairs of first regions with a first color and second regions with a second color alternately arranged in a first direction, and each of the first regions and each of the second regions having a same predetermined width D in the first direction; forming a uniform predetermined illuminance on the reference pattern sheet; detecting directly the reference pattern sheet by a measuring device; detecting the reference pattern sheet through the transparent panel display by the measuring device; and thereby determining a clarity of the transparent display panel. | 02-04-2016 |
20160091419 | ANALYZING AND CORRELATING SPECTRA, IDENTIFYING SAMPLES AND THEIR INGREDIENTS, AND DISPLAYING RELATED PERSONALIZED INFORMATION - Obtaining two spectra from the same sample under two different conditions at about the same time for comparison, where at least one of the spectra measures magnitudes of electromagnetic radiation on at least four different ranges or weightings of wavelengths or frequencies. Classifying a sample using these spectra obtained by a user, and using spectra obtained from different samples by different users to identify the sample. Computing correlations between data related to food and ingredient consumption by one or more users over time, and data related to passive personal log data, user entered feedback, user interaction data or personal information related to those users, and detecting: foods or ingredients to which a user may be allergic or intolerant; a possible medical condition of a user; a possible link between food and ingredient consumption and a medical or health condition; or a similarity between at least two such users. | 03-31-2016 |
20160146667 | THIN-LAYERED DEVICES IN COMPRESSIVE SENSING SPECTROSCOPY - A spectroscopic method using either tunable or preset non-tunable thin-layered devices or a combination of both to modulate compressed-sensing-compliant, spectral modulations and to use intensity measurements of each respective spectral modulation to numerically reconstruct an estimated spectral distribution of the spectral signal such that the estimated spectral distribution is characterized by a totality of spectral bands exceeding the number of spectral modulations by about one half an order-of-magnitude or more. | 05-26-2016 |
