INFORMATION PROCESSING DEVICE AND METHOD

A present disclosure relates to an information processing device and method capable of more easily correcting a color shift.A color shift is corrected on the basis of three-dimensional (3D) projection position of each of optical devices of a projection unit that projects red, green, and blue (RGB) light using the optical devices different from each other. For example, a color shift amount indicating magnitude and a direction of the color shift is derived, and correction is performed in such a manner that the derived color shift amount is reduced. The present disclosure can be applied to, for example, an information processing device, a projection device, an imaging device, a projection imaging device, a projection imaging control device, an image projection imaging system, and the like.
