A biometric authentication apparatus includes an illumination section, an imaging section, a photographic subject placing section, and an authentication section. The illumination section irradiates at least near infrared light onto a biological portion placed in contact with a housing surface. The imaging section images a near infrared light image of the biological portion. The photographic subject placing section is provided in the vicinity of the illumination section, in which at least a part of the light emanation portion of the illumination section on a side where the imaging section is disposed is covered by the photographic subject when the photographic subject is placed. The authentication section performing biometric authentication by making a comparison between a specific pattern extracted from the near infrared light image of the biological portion imaged by the imaging section and a preliminarily registered specific pattern.

Apparatus for determining concentration of creatinine in whole blood or plasma using a 1-methylhydantoinase (NMHase) catalyzed reaction, wherein the invention uses commercially available NMHase and thus eliminates prior art stabilization procedures for NMHase. Conveniently, known Trinder reagents and oxidative couplers are used for the indicator system. It has been found that by judiciously selecting the reagents used for the indicator system and / or varying the amount of enzyme NMHase that is loaded into the assay, the effect of the blank reaction can be minimized in the dynamic range of interest such that concentration of creatinine in normal and pathological levels can be measured directly without having to adjust for a blank reaction caused by bound N-methylhydantoin (NMH).

An image forming apparatus includes an image data input unit configured to take in image data, an image data memory unit configured to save image data, a data output unit configured to output the image data in a specific format, and an image data erasing unit configured to erase the image data saved in the image memory unit after output processing by the data output unit is completed. The image data erasing unit requests the user to make a selection as to whether or not an erasing manipulation for image data as an erasure object is executed, and erases the image data by an erasing method at a different security level according to the selection in response to a selection request.

In an information recording area of a disc-shaped magnetic recording medium, recording columns adjacent to each other relative to a radial direction are formed so as to partially overlap with each other in the radial direction. Each recording column has an overlapping portion which partially overlaps with either of the adjacent recording columns in the radial direction, and a non-overlapping portion which does not overlap with any of the recording columns in the radial direction.

The invention discloses a generating method of non-repeated mark pattern through random spreading marker, which is characterized by the following: combining the manufacturing technique of composite film (paper) and solid marker spreading technique through mechanic vibrating; generating a non-repeated and difficult imitated three-dimensional marker pattern as ID of supplier; checking and inquiring the mark pattern shot by handset in the information checking and inquiring central computer automatically; making the consumer and seller know the genuine-fake of commodity rapidly.

An image processing apparatus, an image processing method, and a program thereof, and a display device are provided, in which reproduction of a secret image from one dispersed image is difficult. A secret image and a reverse image included in at least two types of images are in a relationship of forming image data of an image not correlated with the secret image when luminance values of image data respectively are added pixel by pixel. Included are: a memory 101 that stores the inputted image data; a dispersed image creating / data allocating circuit 102 that creates image data of a plurality of dispersed images in which the secret image is formed when luminance values are added pixel by pixel based on the image data of the secret image and grayscales different from grayscale values of the secret image are allocated to the pixels respectively; and a shutter spectacle control signal creating circuit 103 that outputs a shutter control signal for setting a light shutter to a light transmission state only in a time for outputting image signals in accordance with the image data of the dispersed images.

A recording method, includes: discharging droplets of an ink composition, and adhering the droplets to a recording medium to form a first dot group using an ink jet recording apparatus; and adhering a lustrous ink composition containing a color material containing plate-like particles at least onto the first dot group to form a second dot group.
