Abstract: An image analysis apparatus includes: a distribution data generator that generates, on the basis of a sample image obtained by irradiating a biological tissue with light having an infrared bandwidth, distribution data indicating a distribution of light intensity in the infrared bandwidth in the tissue; a differential calculator that calculates, on the basis of the distribution data, an Nth-order derivative of the distribution of the light intensity in a first wavelength band in the infrared bandwidth, where N is an integer of 2 or more, for each region in the sample image; and an image data generator that converts the Nth-order derivative into a gray-scale value to generate image data.

Abstract: An imaging method includes: irradiating breast tissue with infrared light, detecting light in a narrow wavelength band selected from wavelength bands from 1400 nm or more to 1600 nm or less, among light radiated from the tissue irradiated with the infrared light, and generating, based on the detected light in the narrow wavelength band, an image to specify an area in the tissue containing breast cancer cell aggregation or breast cancer tissue.

Abstract: An image analysis apparatus includes: a calculator that generates, on the basis of a plurality of sample images obtained by irradiating a biological tissue with light having N wavelength bands selected from a wavelength bandwidth from 950 nm or more to 1600 nm or less as a predetermined wavelength bandwidth, sample data on the tissue in the predetermined wavelength bandwidth; and a data generator that compares the sample data with training data on a substance that is a training target, to generate distribution data indicating a distribution of the substance in the tissue.

Abstract: A first control unit (172), which controls the timing at which a first image pickup unit (110) starts exposure, obtains a second difference (?t2) by subtracting a first difference (?t1) from an exposure-output time (AA) of the first image pickup unit (110), and outputs a first control signal (CTR1) for delaying the timing at which the first image pickup unit (110) starts an exposure, by the second difference (?t2). The exposure-output time is a time lag between when the image pickup unit starts an exposure and when output of an image signal obtained by the exposure is started. The first difference (?t1) is a difference between a timing at which the first image pickup unit (110) started outputting a predetermined image signal and a timing at which a second image pickup unit (150) started an exposure for obtaining an image signal that the second image pickup unit (150) outputted immediately after the first image pickup unit (110) started outputting the predetermined image signal.

Abstract: An anonymous purchase and sale system applicable to online shopping using computers between a purchaser and a salesperson is actualized by an anonymous purchase and sale management server, a purchaser terminal device, a salesperson terminal device, an anonymous settlement server and an anonymous delivery system, all of which are linked together via a network. Herein, the anonymous purchase and sale management server activates a commodity sales processor and an analyzer in connection with a sales history storage device, a purchaser's preference storage device and a commodity information storage device. Receiving purchase request information from a purchaser terminal device, the commodity sales processor retrieves from all items of commodity information stored in the commodity information storage device, at least one item of the commodity information that suits to the purchase request information.
