Claim 8:
9. A training data generation method comprising:
selecting some frame images from among a plurality of frame images composing first moving image data as second moving image data;
selecting, as third moving image data, at least some frame images from among the plurality of frame images composing the first moving image data having not been selected as the second moving image data;
selecting, as fourth moving image data, at least some frame images from among the plurality of frame images composing the first moving image data having not been selected either as the second moving image data or as the third moving image data;
generating first training data that is labeled data relating to a specific recognition target from the frame images composing the second moving image data;
learning a first model recognizing the specific recognition target by using the first training data;
generating, by using the first model, second training data that is labeled data relating to the specific recognition target from the frame images composing the third moving image data;
learning a second model recognizing the specific recognition target by using the second training data; and
generating, by using the second model, third training data that is labeled data relating to the specific recognition target from the frame images composing the fourth moving image data.
