Odor detection device, odor detection method, and program

An odor detection device, comprising:

• an odor sensor to detect information on an odor emitted from a source;
• environmental information measurement means for measuring information on an environment, correlated with an amount of water vapor contained in surrounding gas;
• odor information collection means for collecting the information on the odor, detected by the odor sensor;
• difference information acquisition means for acquiring difference information indicating a difference between the information on the environment, measured in a state in which the information on the odor has not been detected by the odor sensor, and the information on the environment, measured in a state in which the information on the odor has been detected by the odor sensor;
• and
• correction means for correcting the information on the odor, collected by the odor information collection means, based on the difference information acquired by the difference information acquisition means.

An odor detection method to be executed by an information-processing device, the odor detection method comprising:

• a first measurement step of measuring information on an environment, correlated with an amount of water vapor contained in gas surrounding a source of an odor, in a state in which information on an odor is not detected by the odor sensor:
• a second measurement step of detecting information on the odor by an odor sensor in a state in which the information on the odor is detected by the odor sensor and measuring information on an environment, correlated with an amount of water vapor contained in gas surrounding the odor sensor;
• a difference information acquisition step of acquiring difference information indicating a difference between the information on the environment, measured in the first measurement step, and the information on the environment, measured in the second measurement step;
• and
• a correction step of correcting the information on the odor, detected by the second measurement step, based on the difference information acquired in the difference information acquisition step.

A non-transitory computer-readable storage medium storing a program causing a computer to function as:

• odor information collection means for collecting information on an odor, detected by an odor sensor to react with an odor generated from a source;
• difference information acquisition means for acquiring difference information indicating a difference between information on an environment, measured in a state in which the information on the odor is not detected by the odor sensor, and correlated with an amount of water vapor contained in gas surrounding the odor sensor, and information on an environment, measured in a state in which the information on the odor is detected by the odor sensor, and correlated with an amount of water vapor contained in gas surrounding the source;
• and
• correction means for correcting the information on the odor, collected by the odor information collection means, based on the difference information acquired by the difference information acquisition means.
