Abstract

A wireless mobile communication device is provided with a light source arrangement configured to be able to output at least one of a steady or sweeping light pulse. The former may be used as a light pointer. The later may be used to facilitate spatial painting of illumination images. In various embodiments, the light source arrangement may include one or more collimated light sources and optionally, one or more mirrors, optically aligned and/or operated in a complementary manner. Further, the device is provided with instructions designed to selectively hold steady or operate the light source(s) and/or the mirror(s) in the complementary manner, activating/deactivating the LS to paint a line (row/column) of pixels in one direction, in accordance with the row/column of a bitmap of an illumination image to be painted, as the device is moved in another complementary direction.
