A method and apparatus for establishing consistent image brightness, especially for a multiple video image seamless display, is provided by storing a set of smoothing factors, one for each detail element of each image, in a memory. Upon projection, the smoothing factors are applied to the brightness components of the associated detail elements of each image. The smoothing factors are selected by applying a standard curve, coarse tuning major curve parameters in response to the appearance of the projected multiple image display, and fine tuning smoothing factors for specific detail elements, the locations of the detail elements being indicated by a cursor on the display.
