Information processing apparatus, information processing method, program, and information processing system

An information processing method comprising:

• calculating vegetation data of multiple time points;
• calculating ratio information, the ratio information being based upon a ratio of detected direct light to detected scattered light, or a ratio of detected total sunlight to detected scattered light;
• determining extracted vegetation data from the vegetation data on a basis of the ratio information,
• generating vegetation change information indicating a time series change of the vegetation data using the extracted vegetation data, and
• outputting the vegetation change information.

A non-transitory computer readable medium storing program code, the program code being executable by a processor to perform operations comprising:

• calculating vegetation data of multiple time points;
• calculating ratio information, the ratio information being based upon a ratio of detected direct light to detected scattered light, or a ratio of detected total sunlight to detected scattered light;
• determining extracted vegetation data from the vegetation data on a basis of the ratio information,
• generating vegetation change information indicating a time series change of the vegetation data using the extracted vegetation data, and
• outputting the vegetation change information.

An information processing system comprising:

• an ambient light sensor including a first light reception section on which a light shielding body casts a shadow and a second light reception section which does not come under an influence of the light shielding body;
• a memory storing program code;
• and
• a processor configured to execute the program code to perform operations comprising:
• calculating vegetation data of multiple time points,
• calculating ratio information, the ratio information being based upon a ratio of detected direct light to detected scattered light, or a ratio of detected total sunlight to detected scattered light,
• determining extracted vegetation data from the vegetation data on a basis of the ratio information,
• generating vegetation change information indicating a time series change of the vegetation data using the extracted vegetation data, and
• outputting the vegetation change information.
