Abstract:
1. A system, comprising: a detection component configured to monitor at least one parameter related to a light source, wherein the light source is part of a projection device; a luminance sensor configured to detect luminance of an image projected by the projection device onto a receiving surface external to the projection device, wherein the luminance sensor is positioned as a function of a difference determined between a field of view of the luminance sensor and an area of the receiving surface on which the image is projected; and a controller component configured to adjust the light source based at least in part on a comparison of the at least one parameter to a threshold, wherein the threshold is selected to increase longevity of the light source, and to modify the threshold based on at least one environmental factor of the projection device, wherein the at least one parameter includes the luminance of the projected image on the receiving surface.
