摘要： PROBLEM TO BE SOLVED: To provide an imaging device which is high in robustness with respect to a noise.SOLUTION: A filter 26 whose spectral transmittance spatially and continuously changes is disposed in the neighborhood (center) of the diaphragm of a main lens 24. An MLA(Micro-Lens Array) 3 configured of a plurality of micro-lens is disposed in the neighborhood of the condensing position of the main lens 24. A code 6 indicates a sensor. A light beam which has passed the filter 26 is temporarily imaged in the neighborhood of the MLA 3, and then allowed to reach the different positions of the sensor by the MLA 3 so that it is possible to simultaneously measure the spectral reflectivity of one certain point of an object 1. Since it is possible to directly obtain the continuous spectral reflectivity simultaneously with photographing, it is unnecessary to perform estimation processing, and it is possible to measure two-dimensional spectral reflectivity which is high in robustness with respect to a noise.

摘要： PROBLEM TO BE SOLVED: To solve a problem in which a user cannot perform image processing such as correction of image data using metadata as the metadata is already deleted when the image data is downloaded from an image management server, because the metadata is regarded as data related to privacy and the image management server separates the metadata from updated image data to delete it and only manages the image data, in a lot of SNS's image management servers.SOLUTION: A transmission device acquires additional information such as metadata from image data and transmits it to an additional information management system 5 along with image identification information, thus the additional information management system 5 can manage the additional information. By this way, the additional information can be downloaded from the additional information management system 5 on the basis of corresponding image identification information when the user downloads the image data from an image management system 7.
