The present technology relates to an information processing apparatus and method that allow a plurality of projection units to project images more easily in cooperation. The information processing apparatus of the present technology forms a group for projecting one contents data in cooperation with other information processing apparatuses including projection units to project images and imaging units to shoot a subject and obtain shot images, shares correction information as information relating to correction made to images projected by the projection units of the information processing apparatuses belonging to the formed group among the information processing apparatuses belonging to the formed group, and updates the correction information for the subject information processing apparatus on the basis of the shot image obtained by shooting the image projected by the projection unit as a subject and the shared correction information. The present technology is applicable to projectors or cameras, or electronic devices including the both functions of projector and camera, computers controlling these devices, and others, for example.
