Abstract:
1. A light measurement device, comprising: a tunable interference filter selecting a wavelength of transmitting light by a drive input; a detecting section detecting light passed through the tunable interference filter and including a plurality of detecting elements arranged in a two-dimensional array; a storing section storing correlation data, wherein the correlation data indicates a wavelength detected by each of the detecting elements of the detecting section for a given drive input; an element identifying section identifying a subject detecting element from among the plurality of detecting elements based on the correlation data stored in the storing section, wherein the subject detecting element receives the light having the wavelength selected by the tunable interference filter based on the drive input; and a light amount obtaining section obtaining an amount of the light having the wavelength selected by the tunable interference filter and detected by the subject detecting element identified by the element identifying section.
