A data creation system creates, based on first image data, second image data for use as learning data to generate a learned model about an object. The data creation system includes a deformer, a remover, a feature acquirer, and a feature assigner. The deformer generates, based on the first image data including a pixel region representing the object, the second image data by causing deformation about the object to the first image data. The remover removes a linear first feature present in the first image data. The feature acquirer acquires a second feature. The feature assigner assigns the second feature to the second image data.
