Abstract: Each camera comprises an image generation unit for generating an image by capturing the image, a moving object detection unit for detecting a moving object from the image and transmitting information on the position of the moving object to the server, and an image transmission unit for, when the camera is selected by the server, transmitting an image. The server comprises an image delivery camera selection unit for selecting some cameras as image delivery cameras from among the cameras based on the information on the position of the moving object transmitted from each of the cameras, an image delivery camera notification unit for notifying the selection result to the cameras, and an image input unit for inputting the images transmitted from the image delivery cameras.

Abstract: A people counting device includes: a person presence region extraction unit which extracts a region in which a person is present by performing person detection in relation to an input image; a person presence state estimation unit which estimates a person presence state from an extraction result; a portion detector selection unit which selects a type of portion detector to be used for people count measurement based on the estimation result, and outputs portion detector information. The people counting device further includes: a portion detection process unit which performs a portion detection process for detecting a portion of a person based on the portion detector information; and a people counting unit which obtains a number of people within the input image from a portion detection process result.

Abstract: In an measuring method for optical transfer function of the invention, irradiating-light from a light source (31) scans an element to be measured within an image sensor of an imaging camera constituted by integrating an imaging optical system and the image sensor. The element to be measured converts sequentially the irradiating-light into an electrical signal and outputs the electrical signal. Further, based on the outputted electrical signal, point spread function data is generated, and subjected to Fourier transform to calculate an optical transfer function. Accordingly, a method is provided for measuring an optical transfer function for properly restoring image degradation due to factors including the position of the imaging optical system within the imaging camera and inter-element cross talk.

Abstract: A process for the preparation of 1-monoalkyl(C.sub.1 -C.sub.4) dimethylsilyl-1-propyne polymers which comprises polymerizing a 1-monoalkyl (C.sub.1 -C.sub.4)dimethylsilyl-1-propyne monomer in the presence of a compound of a transition metal and a member selected from .alpha.,.omega.-dihydropolydialkylsiloxanes and polyalkylhydrosiloxanes in a solvent inert to the polymerization. The polymerization reaction proceeds at low temperatures in an efficient manner. Membranes of the resultant polymer have a high gas transmission and suffer but little degradation when placed under severe temperature conditions.

Abstract: A permselective composite membrane comprising a porous support of a polysulfone or a polyether sulfone in combination with an ultrathin film of a defined polyacetylene whereby an interfacial layer is formed between the support and ultrathin film by the combination of the polysulfone or polyether sulfone and the polyacetylene and facilitates a gas permeability and a separation ratio of an intended gas and a useless gas. The ultrathin film may be covered with another ultrathin film of a different polymer. The interfacial layer made of phthalocyanine or its coordination compound may be provided between the support and the first-mentioned ultrathin film. In this case, various materials for the support and the first-mentioned ultrathin film may be used.

Abstract: A method for making a polymer thin film wherein a first polymer thin film is formed on a support liquid, on which a solution of a second polymer is dropped is described. The first polymer film is pulled in opposite directions to break the first polymer film as a slit, from which the second polymer solution is cast on the support liquid. As a result, the solution can spread uniformly without involving any appreciable irregularity in thickness of a final film product.
