An optical chemical test system and method detects information from areas of a chemical test component in the field of view of a color camera. The chemical test component can be a card or a strip and has a color change test area that changes in appearance when subjected to a target chemical in solution, which changes are detected by the color camera and used by an electronic control device to calculate a concentration value for the target chemical. Other areas of the chemical test component, when provided, calibrate the concentration value by providing further data that is recognized by the color camera and used by the electronic control device for calibration. The chemical test component can include features such as one or more indicia or locations for optical coding, card or strip identifiers and authenticators, one or more reference color areas and one or more reference white areas. Also, a color changing indicator can be provided for liquid temperature monitoring and determining whether or not a sample falls within an acceptable temperature range and/or for adjusting the displayed concentration to compensate for color shifts caused by variation in the fluid temperature. A housing system, when provided, facilitates use of controlled illumination in place of ambient illumination. The system and method are suitable for incorporation into a dishwashing machine for sanitation monitoring.

The present invention relates to a food condition tracking method based on spectral images, a food management method, and a food management device supporting same. The present invention may provide a food condition tracking method based on spectral images, the method comprising the steps in which a processor of a food management device: forms a communication channel with a storage warehouse in which the food is stored; receives, from the storage warehouse, food-related information about food stocked in the storage warehouse; acquires spectral images of the food at regular intervals using a spectroscopic camera arranged so as to able to capture spectral images of the food; and monitors changes in the condition of the food by analyzing the obtained spectral images. The present invention may also provide a food management device supporting the method.

Systems and methods for medical imaging and spectroscopy analysis are disclosed. Some embodiments relate to digital staining. Some embodiments relate to digital staining using hyperspectral or multispectral imaging. Some embodiments relate to digital staining using RGB imaging. Some embodiments relate to analysis of other types of medical imaging and spectroscopy. Some embodiments relate to platform for performing analysis of medical imaging and spectroscopy data.

An imaging device includes a camera, light sources, an optical bandpass filter, and a conversion unit. The camera includes an image sensor including a N-band color filter (where N is a natural number greater than or equal to 3). The M types of light sources (where M is a natural number that satisfies 2MN) have the emission spectral characteristics of having respective peaks in mutually different wavelength ranges within a visible light range and a near-infrared range. The conversion unit generates image signals of M bands each having spectral sensitivity to the corresponding one of the mutually different wavelength ranges by performing a matrix operation on an N-band imaging signal obtained by the image sensor when an article is photographed with the camera. The light application direction and the emission intensity are individually selected for each of the light sources.
