Abstract

A metadata generation apparatus capable of generating metadata, as well as a metadata generation method and program are provided. The sensing device is configured to generate an output value based on a physical amount that is input. The metadata generation apparatus includes a probability density function generation unit and a metadata generation unit. The probability density function generation unit is configured to generate a probability density function of an output value when a specific physical amount is input to the sensing device. The metadata generation unit is configured to generate metadata based on the probability density function.

First claim

The invention claimed is:

1. A metadata generation apparatus configured to generate metadata that is associated with a sensing device,
wherein the sensing device is configured to generate an output value based on a physical amount that is input, and
the metadata generation apparatus comprises:
a probability density function generation unit configured to generate a probability density function of an output value in response to a specific physical amount being input to the sensing device, and
a metadata generation unit configured to generate metadata based on the probability density function.

2. The metadata generation apparatus according to claim 1 ,
wherein the probability density function generation unit is configured to generate a plurality of probability density functions, and
each of the plurality of probability density functions is a probability density function of an output value in response to a specific physical amount that is different from a specific physical amount input to the sensing device in response to another probability density function included in the plurality of probability density functions was generated is input to the sensing device.

3. The metadata generation apparatus according to claim 1 , further comprising:
a physical amount specifying unit configured to specify a physical amount that is input to the sensing device more accurately than the sensing device,
wherein the probability density function generation unit is configured to generate a probability density function based on the physical amount specified by the physical amount specifying unit and an output value.

4. The metadata generation apparatus according to claim 1 ,
wherein the sensing device is installed in an actual use environment.

5. The metadata generation apparatus according to claim 2 , further comprising:
a physical amount specifying unit configured to specify a physical amount that is input to the sensing device more accurately than the sensing device,
wherein the probability density function generation unit is configured to generate a probability density function based on the physical amount specified by the physical amount specifying unit and an output value.

6. The metadata generation apparatus according to claim 2 ,
wherein the sensing device is installed in an actual use environment.

7. The metadata generation apparatus according to claim 3 ,
wherein the sensing device is installed in an actual use environment.

8. The metadata generation apparatus according to claim 5 ,
wherein the sensing device is installed in an actual use environment.

9. A metadata generation method for generating metadata that is associated with a sensing device,
wherein the sensing device is configured to generate an output value based on a physical amount that is input,
the metadata generation method comprises:
generating a probability density function of an output value in response to a specific physical amount being input to the sensing device, and
generating metadata based on the probability density function.

10. A non-transitory computer-readable storage medium storing a program that causes a computer to execute processing for generating metadata that is associated with a sensing device,
wherein the sensing device is configured to generate an output value based on a physical amount that is input,
the program is configured to, which when read and executed, cause the computer to perform operations comprising:
generating a probability density function of an output value in response to a specific physical amount being input to the sensing device, and
generating metadata based on the probability density function.
