The present technology relates to an information processing apparatus and an information processing method enabling a user to visually recognize a surrounding environment promptly based on a sudden change in brightness. An information processing apparatus of the present technology includes an acquisition section that acquires environmental information which is information associated with an environment including an object present in a real space, and a display control section that exercises display control based on the environmental information with respect to form information representing a form of the object over a display section that displays predetermined information in a visually recognizable state while superimposing the predetermined information on the real space based on occurrence of a change in brightness of the real space higher than a threshold. The present technology is applicable to an HMD that displays information while superimposing the information on a scene in front of a user.
