1. A user operation recording apparatus, comprising a processor configured to perform operations comprising:
acquiring image data by performing screen capture of a screen operated by a user, at a predetermined interval set in advance of the screen capture;
detecting the user operation;
estimating an amount of delay time from a user operation time point to a time point at which the user operation is detected by the detection unit;
selecting image data of the user operation time point calculated from the estimated amount of delay time out of the acquired image data;
estimating a range of the amount of delay time independent of the amount of delay time; and
selecting image data immediately before a change of a display state out of the image data in a range of the user operation time point corresponding to the range of the amount of delay time.
