Is the definition of the limits of an image. Sharpness control is a type of computerized edge enhancement. It controls the areas of color transition. Only use the sharpness controls with the aid of a home theater image calibration DVD such as AVIA or Video Essentials. An integral Processing Amplifier allows the adjustment of Brightness, Contrast, Color Saturation, Hue and Sharpness. For HDTV default picture settings are commonly formulated for maximum brightness and contrast for the bright ambient light conditions in a store. Additionally color saturation may be boosted and sharpness adjustments tweaked upwards. Adjusting Sharpness: As usual, to get a handle on what you are adjusting, adjust your sharpness to both ends of the spectrum. Pay close attention to the edges of objects in your picture. When sharpness is cranked all the way up, you start to see distortion at the edges of your images. Bring your level back down to the point where those hard edges disappear, and you are left with a soft, but distinct edges. Sharpness is a little tricky to set using your own DVD. However, for an LCD or DLP projector, it is very easy to set using special calibration software. Full High-Definition Home Cinema Projector introduces a powerful new digital image processing circuit, called the Detail Clarity Processor. This function analyzes the frequency of the video signal in each scene and extracts information on the distribution of the high, medium, and low frequency image components. It then applies appropriate sharpness to each portion of the image based on the extracted information. This brings greater clarity and sharpness to details, by reproducing fine nuances that were lost due to image compression. The resulting images have a more natural, lifelike expression than those of previous image processing methods. |
