METHOD FOR KEEPING UNIFORM LIGHT CHARACTERISTICS IN AN ARRAY OF PROJECTION SCREEN MODULES

摘要

The quality of an image or images projected onto an array of adjacently arranged screens (such as a "video wall" comprising an array of projector/screen modules) is controlled by (a) monitoring a characteristic of light projected to form the image or images for individual respective screens comprising the array; and (b) modifying the characteristic of projected light for one or more particular respective screens if modification of the characteristic is required for the particular respective screens in order to ensure that the characteristic is substantially uniform for projected light for screens across the array.
