Abstract: An acquisition unit acquires vehicle information and a moving image frame as image information captured by an imaging unit from a database. A recognition unit recognizes opening and closing of an eye of a driver, a direction of a face, and a gaze point. An extraction unit extracts, from among the captured images acquired by the acquisition unit, a captured image in which the eye is closed and the face is facing forward in a predetermined range.

Abstract: An acquisition unit acquires vehicle information and a moving image frame as image information captured by an imaging unit from a database. An extraction unit extracts a captured image in which at least one of a direction of a face of an occupant and a position of a gaze point satisfies a predetermined inattentive driving condition from among captured image in which a vehicle speed is equal to or higher than a predetermined threshold value and a steering angle is within a predetermined range.

Abstract: An acquisition unit that acquires a facial image of a driver of a vehicle captured by an imaging unit, a determination unit that determines appropriateness of continuation of driving by the driver based on the facial image acquired by the acquisition unit, and a control unit that, in a case where the determination unit determines that there is a possibility that the continuation of the driving by the driver is not appropriate, causes a display unit on a manager side, the manager managing the driver, to display the facial image based on which the determination unit determines that there is the possibility that the continuation of the driving by the driver is not appropriate are provided.

The high-strength Mg alloy containing Ca and Zn within a solid solubility limit and the remainder having a chemical composition comprising Mg and unavoidable impurities is characterized in comprising equiaxial crystal particles, there being a segregated area of Ca and Zn along the (c) axis of a Mg hexagonal lattice within the crystal particle, and having a structure in which the segregated area is lined up by Mg3 atomic spacing in the (a) axis of the Mg hexagonal lattice. The method for producing the high-strength Mg alloy is characterized in that Ca and Zn are added to Mg in a compounding amount corresponding to the above composition and, after homogenization heat treating an ingot formed by dissolution and casting, the above structure is formed by subjecting the ingot to hot processing.

Abstract: A magnesium alloy of the present invention has the chemical composition that contains 0.02 mol % or more and less than 0.1 mol % of at least one element selected from yttrium, scandium, and lanthanoid rare earth elements, and magnesium and unavoidable impurities accounting for the remainder. A magnesium alloy member of the present invention is produced by hot plastic working of the magnesium alloy in a temperature range of 200° C. to 550° C., followed by an isothermal heat treatment performed in a temperature range of 300° C. to 600° C. The magnesium alloy is preferred for use in applications such as in automobiles, railcars, and aerospace flying objects. The magnesium alloy and the magnesium alloy member can overcome the yielding stress anisotropy problem, and are less vulnerable to the rising price of rare earth elements.
