Abstract: An ink set of radiation curable ink jet compositions, includes: an under layer ink; and an over layer ink, and the under layer ink contains, as a polymerizable compound, 80.0 percent by mass or more of a monofunctional polymerizable compound with respect to a total mass of polymerizable compounds and contains 55.0 percent by mass or more of a polymerizable compound having a nitrogen heterocyclic structure and/or a polymerizable compound having a hydroxy group in total with respect to the total mass of the polymerizable compounds.

Abstract: An information processing apparatus includes circuitry and a memory, the circuitry performing perceptual image conversion of converting two image data generated from one color image data respectively into perceptual images based on human visual characteristics, collation of determining whether the two perceptual images converted by the perceptual image conversion are same, and comparison result outputting of outputting the comparison result by the collation.

Abstract: An inputting device, an electronic instrument using this inputting device, and an inputting method thereof, in which displacement of an operating section in the direction slanting for the X or the Y direction is detected and the movement of a moving object such as a cursor on a display can be controlled easily and precisely, are provided. The operating section is displaced about in the horizontal direction and the vertical direction for a plane being almost parallel to the surface of a cabinet. In case that orthogonal coordinates having the X axis and the Y axis are set on the plane being almost parallel to the surface of the cabinet, horizontal direction sensors detect the displacement of the operating section in the direction slanting for the X or Y direction, in addition to in the X or Y direction. The cursor moves on the display based on the displacement of the operating section about in the horizontal direction.
