Abstract: A colorimeter 1 that measures a chromaticity of a measured object A comprises: a first light source unit 11 that emits first irradiation light having a first spectrum S1; a second light source unit 12 that emits second irradiation light having a second spectrum S2 different from the first spectrum S1; an integrating sphere 61 that has irradiation light including the first irradiation light and the second irradiation light incident thereon; a light receiver 20 that detects measured light resulting from irradiation of the measured object A with the irradiation light emitted from the integrating sphere 61; and a controller 50 that calculates an optical spectrum of the measured light based on a detection signal of the measured light. A superimposed spectrum S of the first spectrum S1 and the second spectrum S2 corresponds to a reference spectrum S0 of a standard light source as reference for calculating the chromaticity.

Abstract: A non-transitory computer-readable medium stores computer-readable instructions. The instructions, when executed, cause a processor of a sewing data generation device configured to generate sewing data to perform processes. The processes include acquiring pattern data to sew an embroidery pattern. The processes further include setting an outline having an offset portion and a complementary portion on the basis of the pattern data. The outline is a single line surrounding the outside of a contour of the embroidery pattern. The offset portion is a part of the single line and is offset from the contour toward the outside of the embroidery pattern by a predetermined amount. The complementary portion is another part of the single line and being offset from the contour toward the outside of the embroidery pattern by an amount larger than the predetermined amount. The processes also include generating sewing data to sew the outline.
