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.
Claims12
A method for outputting freshness information, the method comprising the steps of:
- obtaining, using a hardware processor, information indicating luminance of an iris portion of an eye of a fish onto which ultraviolet light is radiated;
- and
- outputting, using the hardware processor, the freshness information indicating freshness of the fish on the basis of the foregoing information.
A freshness information output apparatus comprising:
- an obtainer that obtains information indicating luminance of an iris portion of an eye of a fish onto which ultraviolet light has been radiated;
- and
- an outputter that outputs freshness information indicating freshness of the fish determined on the basis of the foregoing information.
A non-transitory computer-readable recording medium storing a control program for causing a device including a processor to execute a process for determining freshness of a fish, the process comprising the steps of:
- capturing an ultraviolet image of an eye of the fish onto which ultraviolet light has been radiated;
- and
- extracting a luminance value of an iris portion from the ultraviolet image, determining the freshness of the fish on the basis of the luminance value of the iris portion, and outputting freshness information indicating a result of the determination.
