Abstract: The present technology relates to an image processing apparatus and method for enabling a relative posture between a projection unit and a shooting unit to be found more easily. According to one aspect of the present technology, a correspondence between a projection image and its shot image is detected by use of a pattern shot image which is a shot image of a pattern projection image as a projection image of an image including a pattern. The present technology can be applied to an electronic device including a projector or camera or the functions of both, a computer for controlling the same, and the like.

Abstract: There is provided an information processing apparatus, an information processing method, and a program capable of reducing a decrease in resolution in overlapping areas of multiple projection in cases where a plurality of projectors is used to perform the multiple projection onto an object. An information processing apparatus according to one aspect of the present technology generates, in regard to a plurality of projectors irradiating an object serving as a projection target with projection light rays as superimposing light rays depicting a projection image having pixels, mask information for regulating intensity of the corresponding light ray of each pixel of the projection image. The mask information includes information indicating, in regard to the object having a surface including a predetermined position, that the position is irradiated by a predetermined projector. The present technology can be applied to computers each of which causes a plurality of projectors to project images.
