Information processing method of predicting calculation amount suitable for recognizing motion of object

An information processing device, comprising:

• a processor;
• and
• a memory that stores a program,
• wherein when the program is executed by the processor, the program causes the processor to execute:
• acquiring, from a plurality of time-series images in which an object is captured, first information including at least a plurality of positions or a plurality of sizes of the object;
• executing, based on the first information, prediction processing of predicting second information including at least one of a position or a size of the object at a next time point in a time series;
• recursively executing the prediction processing based on the first information and the second information to predict third information including at least one of a position or a size of the object at a time point further next to the next time point;
• executing recognition processing of recognizing the motion of the object based on the second information and the third information;
• and
• determining a total number of times of recursion of the prediction processing in accordance with a recognition rate of the motion of the object recognized as a result of the recognition processing.
