The aperture is contracted during dark scenes for truer black tones and enhanced detail, while it is enlarged for bright scenes to maximize light output and enable a wider dynamic range. No matter what type of content is on, the W500 ensures that you get the very best viewing experience. The W500 not only converts SD content such as analog TV broadcasts to HD-quality video, but it analyzes an amazing 1,024 pixels in the source for each pixel in the final HD version for native HD-like picture quality.
