@article{Laird2006_0,<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Abstract = {Recent commercial liquid crystal display (LCD) televisions are larger and brighter than traditional televisions impacting the viewing conditions in which they are viewed. These changes in viewing conditions may require different electro-optical transfer functions (EOTFs) for the LCD televisions than those in traditional TVs. Here we examine how various electro-optical transfer functions affect the preferred image quality of test images with changes in brightness and surround illumination conditions. In the first experiment, gain, offset, and gamma (GOG) functions with a range of gamma values and changes in contrast of the intrinsic EOTFs were simulated by manipulating the test images. In a darkened room, image preference for the various simulated EOTFs were determined using paired-comparison for a set of ten test images. The procedure was repeated at a lower luminance level by placing a non-spectrally-selective neutral filter in front of the screen. The results indicated that, in general, a gamma of 1.6 was the most preferred. This preference for 1.6 was more marked at the lower screen luminance level. In a second experiment, the procedure was repeated in a more natural viewing environment by introducing a dim surround behind the display that was 10% of the luminance of the display’s unfiltered white point. With this surround, the improvement in image preference with change in gamma-functions at both screen luminance levels was more enhanced. The results indicate that image preference for different transfer functions are dependent on the intensity of the displays and that this dependence is maintained under natural viewing conditions with a dim surround.},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Author = {Justin L.
