Abstract: A wearable environmental sensor device includes a temperature/humidity sensor disposed on a wall surface of a housing that is exposed to an environment and configured to measure ambient environmental information around a living body, and a protective structure formed around the temperature/humidity sensor. The temperature/humidity sensor is disposed, directly or via a support structure, on or over the wall surface of the housing, wherein the wall surface faces substantially downward from the living body when the wearable environmental sensor device is attached to the living body and the living body is in a standing posture. The protective structure has respective ventilation holes provided in two or more pairs of opposed surfaces thereof each facing in a direction other than a vertical direction of the living body when the wearable environmental sensor device is attached to the living body and the living body is in the standing posture.

Abstract: An objective optical system for endoscope consists of, in order from an object side, a first negative lens L1 which is planoconcave, and of which a flat surface is directed toward the object side, a second meniscus lens L2 having a convex surface directed toward an image side, a third positive meniscus lens L3 having a convex surface directed toward the object side, a fourth positive lens L4, and a cemented lens in which fifth positive lens L5 and a sixth negative lens L6 are cemented. Focusing is carried out by the third positive meniscus lens moving along an optical axis AX, and the following conditional expressions (1-1) and (1-2) are satisfied: 0.41<|flp/f2<1??(1-1), and 0.55<d45/flp<1??(1-2).

Abstract: Provided is an image processing apparatus including a high-luminance-pixel identifying unit that identifies pixels having luminance values equal to or greater than a prescribed threshold in an input image; a frequency-distribution creating unit that creates a frequency distribution of the luminance values of all of the pixels identified by the high-luminance-pixel identifying unit; a storage unit that stores a target frequency distribution; and a luminance correcting unit that corrects the luminance values of the pixels identified by the high-luminance-pixel identifying unit so that the frequency distribution created by the frequency-distribution creating unit approaches the target frequency distribution stored in the storage unit.
