1. A measurement device comprising:
a first image capturing unit configured to obtain a first image by image-capturing liquid containing tangible components;
a second image capturing unit having an image-capturing magnification higher than that of the first image capturing unit and which is configured to obtain a second image by image-capturing the liquid containing tangible components simultaneously with the first image capturing unit; and
a calculation unit configured to:
clip the tangible components from the first image and the second image,
sort the clipped tangible components from the second image into different types, and
calculate a total number of the tangible components clipped out from the first image, a ratio of a number of each of the tangible components of the different types clipped out from the second image to a total number of the tangible components clipped out from the second image and then the number of each type of the tangible components in the first image based on the total number of the tangible components clipped out from the first image and the ratio of a number of each of the tangible components of the different types.
