Abstract: A method of displaying an image having a first aspect ratio with a display device having a second aspect ratio includes receiving image data for the image, buffering the image data and creating a frame of the image at the first aspect ratio, defining a first sub-frame and a second sub-frame for the frame of the image at the second aspect ratio, including spatially offsetting the second sub-frame from the first sub-frame in one direction, and alternating between displaying the first sub-frame in a first position and the second sub-frame in a second position spatially offset from the first position with the display device, including optically scaling a displayed image of the first sub-frame and a displayed image of the second sub-frame in the one direction.

Abstract: A method of monitoring an illumination source including a reflector and a lamp. A reference orientation is defined where the reflector and a light producing luminary of the lamp are aligned to optimize light intensity reflected from the luminary to a desired target. The orientation of the lamp is monitored, and changes from the reference orientation are reported as an indication of a reduction in light intensity reflected from the luminary toward the desired target.

Abstract: Various systems, methods, and programs embodied on a computer-readable medium are provided for calibrating a laser power in an optical disc drive. In one embodiment, a plurality of marked segments of a calibration pattern are created on a label surface of an optical disc with a laser in the optical disc drive. The marked segments are created by the application of assorted quanta of radiant energy from the laser. The reflectivity of the marked segments is measured. Ultimately, the laser power of a laser in the optical disc drive is set for writing a label based upon the reflectivities measured for each of the marked segments for each quantum of radiant energy.
