Classification: CPC G | IPC G

Claim 2:
3. A training data generation apparatus, comprising:
a processor;
a memory coupled to the processor and storing program instructions executable by the processor to:
detect a scene change point of first moving image data;
divide a plurality of frame images constituting the first moving image data into a plurality of groups with the detected scene change point as a division point;
randomly select, from each of the plurality of groups, a first given number of the frame images as second moving image data;
randomly select, from each of the plurality of groups from which the second moving image data was extracted, a second given number of the frame images as third moving image data, the second given number being larger than the first given number;
generate first training data that is labeled data relating to a specific recognition target, from the first given number of the frame images that constitute the second moving image data;
learn a first model recognizing the specific recognition target by using the first training data; and
generate, by using the first model, second training data that is labeled data relating to the specific recognition target, from the second given number of the frame images that constitute the third moving image data.
