Abstract: The present disclosure relates to an information processing device and a method, in which an image quality improvement technology required for reproducing contents can be easily used. Image quality improvement technology information regarding an image quality improvement technology for improving an image quality of an image to be encoded is generated, a content file storing the encoded data of the image is generated, and the image quality improvement technology information is stored in the content file. Furthermore, encoded data of an image to be reproduced is acquired from a content file on the basis of the image quality improvement technology information regarding an image quality improvement technology for improving an image quality of an image, and the encoded data is decoded. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.

Abstract: An information processing method performed by an information processing system, the method comprising: an information processing system that processes information concerning a test using that includes a test piece, a first device, and a second device communicably connected with the first device and processes information concerning a test using the test piece. The test piece develops a color depending on whether a test object is present. The first device transmits individual identification information provided to the test piece and a captured digital image including a coloring area to a second device. The second device determines whether the test object is present and stores the digital image in a state of being associated with the individual identification information.

Abstract: A nonvolatile semiconductor memory device that have a new structure are provided, in which memory cells are laminated in a three dimensional state so that the chip area may be reduced. The nonvolatile semiconductor memory device of the present invention is a nonvolatile semiconductor memory device that has a plurality of the memory strings, in which a plurality of electrically programmable memory cells is connected in series. The memory strings comprise a pillar shaped semiconductor; a first insulation film formed around the pillar shaped semiconductor; a charge storage layer formed around the first insulation film; the second insulation film formed around the charge storage layer; and first or nth electrodes formed around the second insulation film (n is natural number more than 1). The first or nth electrodes of the memory strings and the other first or nth electrodes of the memory strings are respectively the first or nth conductor layers that are spread in a two dimensional state.

Abstract: A contaminant detector includes a detection object that is inclined relative to a horizontal direction in a drainage unit for accumulation of discharged water and on which a contaminant is to be deposited and a detection unit configured to emit energy toward the detection object to detect a contamination state of the detection object. The detection unit includes a transmission and reception module configured to emit and receive energy, a calculation module configured to calculate an amount of energy received from the detection object by the transmission and reception module, and a determination module configured to determine, based on the amount of energy calculated by the calculation module, the contamination state of the detection object.
