1. An information processing apparatus comprising:
an acquirer configured to acquire video image information indicative of a video image obtained by photographically capturing a table, on which a vessel of a first type to serve food or beverage to be consumed by multiple people and a plurality of vessels of a second type in each of which a portion of the food or beverage is to be served are arranged, and the multiple people;
an identification information generator configured to generate, based on the video image information, first identification information for identifying each of the multiple people, second identification information for identifying each of the vessel of the first type and the plurality of vessels of the second type, and third identification information for identifying a type of the food or beverage;
an estimator configured to estimate, based on the video image information, an amount of food or beverage served in each of the vessel of the first type and the plurality of vessels of the second type;
a first determiner configured to determine, based on the video image information, whether an amount of food or beverage served in the vessel of the first type at a point in time of a determination is decreased compared to an amount of food or beverage served in the vessel of the first type at a point in time that is a predetermined period prior to the point in time of the determination;
a second determiner configured to, when a result of the determination by the first determiner is affirmative, determine, based on the video image information, whether food or beverage served in the vessel of the first type was consumed by one person of the multiple people, or the food or beverage was moved into one vessel of the plurality of vessels of the second type; and
a consumption information generator configured to, when a result of a determination by the second determiner indicates that food or beverage served in the vessel of the first type was consumed by the one person, generate consumption information in which an amount of food or beverage consumed by the one person, the one person, and the type of the food or beverage are associated with each other,
wherein the estimator is configured to, when the result of the determination by the second determiner indicates that the food or beverage was moved into the one vessel, increase the amount of the food or beverage served in the one vessel of the second type by an amount of decrease in food or beverage served in the vessel of the first type.
