The LEDs are arranged in one or more rows, at a central zone. The lens has an incident surface receiving light from the LEDs, and an exit surface from which the light goes out, being expanded. In the exit surface, in an optical-axis-containing sectional plane viewed laterally along the orientation in which the LEDs are arrayed, the len's curvature C in a minute interval along the exit surface is maximum in a range 60°

In a special mode, a superficial layer wavelength set, a middle layer wavelength set, and a deep layer wavelength set are selected successively. Each wavelength set is composed of 3 different types of narrowband light applied successively to an internal body portion. A wavelength set table specifies the number of repetitions of each wavelength set. A controller controls a wavelength band switching element to apply every type of the narrowband light of each wavelength set, and to apply each wavelength set for the number of repetitions specified by the wavelength set table. A CCD captures images of the internal body portion under illumination of the narrowband light of the respective wavelength sets. A blood information calculation section calculates oxygen saturation levels of hemoglobin in blood vessels in the superficial, middle, and deep layers based on image signals, respectively. This provides information on cancer progression.

There is provided an image recording apparatus for assisting an observer who observes an observed person. The image recording apparatus includes an image-capturing section that captures an image of the observed person, an observation result input section that inputs a result of the observation done on the observed person by the observer, an observer's point of sight position judging section that judges whether the observer looks at the observed person when the image-capturing section captures the image of the observed person, an image extracting section that extracts an image of the observed person for which the observer's point of sight position judging section judges that the observer looks at the observed person, a physical status quantifying section that quantifies a physical status of the observed person by analyzing the image of the observed person which is extracted by the image extracting section, for an observation result which is input by the observation result input section and corresponds to the image of the observed person which is extracted by the image extracting section, and a physical status data storing section that stores thereon physical status quantified data which is generated by the quantification by the physical status quantifying section, in association with the corresponding observation result.

A lighting device includes a substrate, a LED element, and a lens. A light exit surface of the lens includes a first light exit surface and a second light exit surface. A curve obtained by cutting the light exit surface by a plane including the optical axis has, on a boundary between the first light exit surface and the second light exit surface, a change point at which a rate of inclination decreases discontinuously. An angle between the optical axis and a line segment connecting the change point and a light emission center of the LED element is approximately equal to an emission angle with the highest light intensity, among emission angles, when light rays emitted from the light exit surface are sorted by respective emission angles.

A switcher, residing in a memory, detects a connectable network when a terminal is powered on. When a network is detected, a communication unit issues a message to a processor. The processor detects whether the terminal has ever been connected to the detected network and whether the profile of the network is registered. If the processor determines that the profile of the network is registered, a connection to the network is established in accordance with the profile. If the processor determines that no profile of the network is registered, a new profile of the network is produced, and then registered. The present invention is applicable to personal computers.
