Two-dimensional colorimeter, and spectral sensitivity correcting method

A two-dimensional colorimeter includes: an image sensing section, having an image sensor constituted of a number of pixels arranged in a two-dimensional manner, for sensing an object image to be measured to acquire a two-dimensional image; a discriminator for discriminating whether a targeted color with respect to the two-dimensional image acquired by the image sensing section is to be corrected in terms of a pixel or pixels; and a calculator for performing a calculation to apply predetermined correction information corresponding to the color to be corrected to the two-dimensional image in terms of a pixel or pixels, based on a discrimination result by the discriminator.
