Abstract: A freshness estimation method includes obtaining an absorbance spectrum that is obtained by irradiating an eye of a fish with light having all or part of a wavelength band from 315 nm to 450 nm; and estimating freshness of the fish by using a shape of the obtained absorbance spectrum.

Abstract: An elapsed-time determination apparatus includes: a storage unit that stores correlation information indicating a correlation between a state of a melanophore of a fish and an amount of time elapsed since the death of the fish; an acquisition unit that acquires an image of a fish; an analysis unit that detects a state of a melanophore of a fish by analyzing an image acquired by the acquisition unit; and a determination unit that determines the amount of time elapsed since the death of the fish in accordance with the state of the melanophore of the fish detected by the analysis unit, based on the correlation information, and outputs determination results.

Abstract: In a method for outputting freshness information used by a freshness information output apparatus, ultraviolet light is radiated onto an eye of a fish, an ultraviolet image of the eye of the fish is captured using an ultraviolet camera, a computer analyzes the ultraviolet image to determine freshness of a fish on the basis of luminance of an iris portion of the eye of the fish, and freshness information indicating the freshness of the fish is output to a display.
