    Abstract: This invention permits to validate the measures registered by a hyperspectral measuring system, by means of at least one Reference made by a mosaic of pieces of different colours arranged ahead the item to be measured. In this way, during measurement, the system registers first the Reference, having known certified spectral values, then the item and, if required, when coming back, the Reference again, so as to register the error of measurement and/or even correct the spectrometric values of the sample.

    Abstract: A method and system for effecting an appearance model correction for a display unit, e.g., a CRT, using a polynomial-based algorithm is described. The correction may be effected in real time and is based on gamma values associated with the display. Strong correlations with the CIECAM02 specification are achieved according to the present disclosure. The correction functionality may be implemented using a colorimeter that includes a plurality of sensors/filter systems with non overlappng spectral responses, adequate for providing data capable of translation into standard coordinates system such as, CIE XYZ, CIE L* a* b*, or CIE Luv, as well as non-standard operable coordinate systems. The field of view of the colorimeter is chosen to closely track the response of the human eye using an optical path configured to select and limit the field of view in a manner that is insensitive to placement of the colorimeter on the source image. The optical path from the source image to the sensor is configured to select preferred light rays while rejecting undesirable light rays to maximize the signal/noise ratio. A rearward facing sensor channel is included to simultaneously measure ambient light impinging on the source image and feedback means to provide status and/or change of information.

    Abstract translation: 描述了使用基于多项式的算法对诸如CRT的显示单元进行外观模型校正的方法和系统。 校正可以实时地实现，并且基于与显示相关联的伽马值。 根据本公开实现了与CIECAM02规范的强相关性。 校正功能可以使用包括具有非叠加光谱响应的多个传感器/滤波器系统的色度计来实现，该传感器/滤波器系统足以提供能够转换成标准坐标系统的数据，诸如CIE XYZ，CIE L * a * b *或 CIE Luv，以及非标准可操作的坐标系。 选择色度计的视野以使用配置成以对色度计放置在源图像上不敏感的方式选择和限制视场的光路来密切跟踪人眼的响应。 从源图像到传感器的光路被配置为选择优选的光线，同时抑制不期望的光线以使信号/噪声比最大化。 包括向后的传感器通道以同时测量照射在源图像上的环境光和反馈装置以提供信息的状态和/或变化。

    Abstract: According to the present invention, there is provided a colorimetry device which when measuring color of a leaf of a plant, makes it possible to perform the measurement while leaving the plant as it is, without cutting off the leaf and damaging the plant. The colorimetry device comprises a light source for irradiating light to a measured object, a cover part provided with a take-out port for taking out light diffused from the measured object, and a placing part on which the measured object is placed, in which colorimetry device the measured object is put between the cover part and the placing part, so as to effect the color measurement of the measured object. In this case, the placing part and the cover part are connected with each other by a hinge mechanism in an openable and closable manner, so that when the measured object is placed on the placing part and the cover part is made to be in a closed state, a measurement space dividing section for defining a measurement space between the cover part and the placing part is provided. At this time, since a gap is formed between the measurement space dividing section and the measured object, inevitably causing light to leak from the outside, a function of correcting the effect of the external light is also provided. Moreover, measuring ligth is also arranged to be irradiated from the rear face of the measured object. Thereby, light transmitted through the measured object can be detected, enabling a more exact color measurement to be performed in consideration of transmission property of the measured object.

    Abstract: Color measurement instrument (10) including an integrating sphere (12), a beam splitter (16), a video camera (18), and a spectrograph (20). The beam splitter (16) is aligned with the viewing port (32) of the spectrophotometer to deliver the light reflected from the sample (S) to both the video camera (18) and the spectrograph (20). The video camera (18) provides an image of the position of the sample (S) with respect to the viewing port (32) of the sphere (12), enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.
