Information of plant based on color of a surface of plant is acquired from image data obtained by imaging plant, allowing to acquire information of plant at low cost, compared to chlorophyll meter or spectroscopic analyzer. In crop production like rice plant, fertilization management including fertilizer application management like fertilizer amount determination, or other agricultural works, is supported through a smart phone or the like based on data to be observed, like converted leaf color value is calculated from image data obtained by crop imaging. Camera is connected to smart phone. Converted leaf color value can be obtained from image data obtained by imaging leaf of rice plant by camera. Converted leaf color value is transmitted to management server, for example, amount information of applied fertilizer is required in case where converted leaf color value is less than standard, can be obtained as management information for fertilizer application management.

Service can be offered free of charge and the cost of a skin condition measuring device can be reduced by effectively using data on the occasion of obtaining an analysis result by transmitting measurement data by the skin condition measuring device to a server of a company providing a service of analyzing the measurement data. When a request is made from a contractor client to acquire data registered in a measurement data database, authentication is executed based on a contractor ID input from the contractor client. Additionally, when the measurement data database is searched from a contractor database based on the contractor ID, a search level and an access level are obtained. The contractor client is permitted to search the measurement data database within a range of the search level and the access level.

Management system for skin condition measurement analysis information and management method for skin condition measurement analysis information

Provided are a system and method for surface condition measurement and analysis to effectively utilize image data photographed when a surface as an object is photographed regularly and continuously. When a surface as an object is sequentially photographed as time passes and the photographed image data is sequentially stored, the sequentially stored images are compared and the presence or absence of image regions among the images that nearly coincide with each other is determined. When there are images with image regions that nearly coincide with each other, a coordinate system having one image as a reference is set, and a position of the other image in the coordinate system is determined. When an image with an undetermined position overlaps with an image with a determined position, including images photographed subsequent thereto, the position of the image is determined.

Lens information management system for surface condition measurement and analysis and information management method for surface condition measurement and analysis

A method of producing an optical element, in which a first and a second die are cooperated with each other so as to press-mold a material in order to produce an optical element including a lens portion, the first die has a circular cross-sectional shape, and the second die defines therein an interior space having a polygonal cross-sectional shape with respect to the direction of die-fastening, the first die is adapted to enter into the interior space of the second die in the direction of die-fastening in the interior space so to press-mold the material in order to form the lens surface while the material is bulged out through gaps between the first die and the second die around the lens surface whereby forming protrusions. An optical element and a mold assembly for an optical element are also provided.

Production method of optical element, optical element forming mold and optical element

A lens is manufactured by hardening soft material filled inside a molding tool by cooling. The lens includes a convex lens portion having an optical axis, and a marking portion located outside of an effective diameter of the lens portion. The shape or the position of the marking portion is set to prevent deformation of the marking portion by contact with the molding tool due to shrinkage of the material during cooling.
