Abstract: A color conversion table generation device, that generates a color conversion table defining a correspondence relationship between a coordinate value of input color space and a use amount of a plurality kinds of color materials, includes a boundary position setting unit that receives selection of setting of a boundary position at which use of a specific color material included in the plurality kinds of color materials is started or ended in a predefined axis provided in the input color space, a usability determination unit that determines whether the specific color material is to be used at a grid point defining the correspondence relationship or not, based on the boundary position in the predefined axis, and a use amount setting unit that sets a use amount of the specific color material at the grid point in a case where it is determined that the specific color material is to be used.

Abstract: A resonator element includes a base portion, and a vibrating arm which extends from the base portion and on which a weight portion is provided, and the weight portion includes a first weight portion which is disposed on one main surface of a distal end portion of the vibrating arm, and a second weight portion which is disposed on the distal end side with respect to the first weight portion and has a thickness smaller than that of the first weight portion. The vibrating arm transmits an energy beam, and a laser incidence area where incidence of the energy beam to the inside of the vibrating arm is allowed, is disposed in a position of the other main surface on the opposite side of the vibrating arm overlapped with the second weight portion.

Abstract: The purpose of the present invention is to create a color conversion table with good gradation using a plurality of inks from a printer. Provided is a method for creating a color conversion table, the method comprising: a virtual color value determination process in which a plurality of virtual color values at a lattice point in a color conversion table in a virtual color space are determined; and an ink amount determination process in which a combination of ink amounts at the lattice point in the color conversion table is determined on the basis of a predetermined conversion coefficient and the virtual color values. At least one of the virtual color value determination process and the ink amount determination process is executed using a cubic spline function that is defined from the plurality of virtual color values or the ink amounts.

Abstract: A correction table generation method includes acquiring a first color value of an apparatus non-dependent color system corresponding to an input value of a multi-dimensional apparatus dependent color system in an input lattice point of the color conversion table and generating a multi-dimensional conversion table in which a first apparatus dependent value of the apparatus dependent color system having color conversion table color value characteristics is correlated with a second apparatus dependent value having a color value of the apparatus non-dependent color system and approximate linearity over multiple dimensions, and the generating of the multi-dimensional conversion table includes determining a target color value for multiple dimensions having approximate linearity over the multiple dimensions with respect to the input value, and determining a first apparatus dependent value corresponding to a second apparatus dependent value using the input value, the target color value for the multiple dimensions, and the first color value.
