Abstract: A measuring device includes a measuring unit that measures the morphology of a convex portion, and a position fixing unit that includes an opening in which the convex portion is to be disposed and a fixing member which includes the opening at a center thereof and against which the periphery of the convex portion is to be pressed. The size of the opening of the position fixing unit is capable of being changed.

Abstract: In an immunochromatographic assay method for assaying a specimen by reacting a reagent held by a carrier and the specimen with each other, and by obtaining an image signal by imaging a reagent portion that has been reacted, and by measuring, based on the image signal, the color-developed state of the reagent caused by the reaction, the carrier holds reagents in such a manner that they do not extend continuously for the full length of the carrier in any one of two-dimensional directions along the surface of the carrier. A morphological opening operation is applied to the image signal, with respect to each of the two-dimensional directions, by using a structuring element the size of which is less than or equal to a signal change width of the reagent portion that has developed color, and the color-developed state is measured based on the image signal after the opening operation.

Abstract: In an immunochromatographic assay method for performing an assay related to a specimen by reacting a reagent held by a carrier and the specimen with each other, and by obtaining an image signal by imaging a reagent portion by a camera, and by measuring, based on the image signal, the color-developed state of the reagent, a morphological opening-operation is applied to the image signal by using a structuring element the size of which is less than or equal to a signal-change-width of the reagent portion that has developed color, and a morphological opening-operation is applied to the image signal by using a structuring element the size of which is larger than the signal-change-width of the reagent portion that has developed color. The color-developed state is measured based on a difference signal obtained by performing a subtraction between the image signals to which the opening-operations have been applied respectively.
