Abstract: The present technology relates to an image processing apparatus and a method capable of performing calibration of a correction amount in brightness correction more easily. The image processing apparatus according to the present technology performs blending calculation for correcting brightness of an image in accordance with a distance from a projection unit configured to project the image to a projection surface onto which the image is projected, and in accordance with a characteristic of the projection unit. The present technology can be applied, for example, to a projector, a camera, or an electronic apparatus including both function of a projector and a camera, a computer that controls these, and to a system in which an apparatuses having a projector and a camera are operating in cooperation.

Abstract: This invention overcomes disadvantages of the prior art by providing a system and method that allows for the calibration of a display system using one or more cameras whose lenses are not modeled, or are modeled with limited accuracy, and are potentially incapable of imaging the entire projector system.

Illustratively, the cameras serve mainly to map the projectors into one coordinate system, where the overlap between the projectors can be established very precisely using a camera, even if the model of the camera lens properties is not known, or known only minimally.

Abstract: A method is disclosed herein that derives a post-alignment transform that is applied to the input source after the application of an alignment transform to ensure that when each source illuminates the screen, the display is aligned and retains the correct displayed aspect ratio.
