Abstract: A computer system for seeding a formulation engine receives spectrometric data from a target coating. The computer system processes the spectrometric data through a probabilistic colorant analysis. The probabilistic colorant analysis generates a set of colorants. Each colorant within the set of colorants is associated with a calculated probability that the associated colorant is present within the target coating. Additionally, the computer system adds at least a portion of the colorants within the set of colorants to a formulation engine. The portion of the colorants is added to the formulation engine in order of decreasing probability. Further, the computer system generates, from an output of the formulation engine, a coating formulation that is calculated to match the target coating within a predetermined qualitative threshold.

Abstract: Color calibration for digital pathology is provided. A standard glass slide is prepared with a specimen having zero or more stains. The specimen is scanned a first time using a hyperspectral imaging system to produce a first digital image having XYZ color values. The specimen is scanned a second time using a digital pathology imaging system to produce a second digital image having RGB color values. The first and second digital images are then registered against each other to align the digital image data. Individual pixels of the first and second images may be combined in the registration process so that the first and second digital images have substantially similar pixel sizes. A lookup table is generated to associate XYZ color values to RGB color values. Once the lookup table has been generated, it can be used to present RGB color on a display using the corresponding XYZ color.

Abstract: An optical sensing circuit includes a capacitor, and a light sensing unit, a compensation unit, and a switching element coupled to the capacitor. The light sensing unit includes a first light sensing transistor for sensing a first color. The compensation unit includes a second light sensing transistor for sensing a second color. The spectra of the second color and the first color do not overlap each other. When the light illuminates, the light sensing unit generates a first current and the compensation unit generates a second current. The second current reduces the magnitude of the charging or discharging current when the capacitor is charged or discharged by the first current. When the switching element turned on, the voltage of the capacitor is read to determine the color of the light. The voltage level of the gate of the first or second light sensing transistor is adjustable.

Abstract: A light source device 100 has a light source 101 which emits light to be irradiated, a chromaticity measurement part (spectrometer) 109 for measuring the chromaticity of the emitted light emitted by the light source, a chromaticity adjustment part 120 capable of placing/removing chromaticity adjustment-use filters CHA and CHB onto/from the light path LP of the emitted light and capable of adjusting the chromaticity of the emitted light by placement/removal of the chromaticity adjustment-use filters, and a control part 400 which monitors a change of the chromaticity of the emitted light according to the results of measurement of the chromaticity measurement part and controls placement/removal of the chromaticity adjustment-use filters of the chromaticity adjustment part onto/from the light path LP so that the chromaticity becomes the chromaticity which is set in advance as a target. Due to this, the light source device 100 can emit light having the same color even in the face of changes along with the elapse of time and variations in the specifications of the optical parts.
