1. A learning data generation device comprising:
processing circuitry configured to
receive an input of a learning video image in which motion of a spinning sphere is recorded and an initial value of a size of a contour of the recorded sphere in the video image, set a plurality of set values of the size of the contour based on the initial value, and obtain an estimated value of a spinning rate of the sphere based on the learning video image, for each of the set values;
receive an input of a true value of the spinning rate of the sphere, the true value being obtained in advance for the learning video image, and determine at least one of a plurality of the set values respectively corresponding to a plurality of the estimated values selected in order of closeness to the true value, as a determined value of the contour; and
output the learning video image and the determined value as learning data.
