Dedicated projectors and devices with projection abilities such as digital cameras or camcorders have projections that are corrected to compensate for irregularities in the surfaces receiving the projection. The image data being projected is compensated to account for the irregularities by observing the irregularities with a camera to produce image data and creating the compensation based on that image data. Irregularities of the projection receiving location including angular relationships to the projector causing keystoning, noisy surfaces with reflectivity or absorption, color patterns, non-planar regions, intervening objects, and the like may be accounted for during the compensation. The projection of the image itself may be utilized to capture the result of projecting onto the irregularities. Projection of target grids, such as using infrared, may be used to capture the result of projecting onto the irregularities. The captured image may be processed to produce a compensated image to be projected.
