HP Introduces Wobulation To Double Resolution of DTVs, Projectors
Posted by Suhit Gupta in "NEWS" @ 08:00 AM
"Hewlett-Packard has developed technology called "wobulation" that it says will dramatically improve the image quality of HP digital projectors due to start arriving in 2005. First-generation "2X" wobulation will double the effective resolution of digital projectors without changing the number of pixels it displays, and a later "4X" version will provide further improvements, the Palo Alto, Calif.-based company said Wednesday. The technology means that high-quality projectors can be made with lower-cost components, HP said."
This new technology called wobulation works by shifting an image slightly in one direction or another, the shift being less than the amount of the width of any pixel. Due to this shift and by overlapping these shifted images, they are able to achieve an effective resolution of 2,048 pixels by 1,536 pixels or 4,096 pixels by 3,072 pixels for a 1024-by-768 pixel image display with 2x and 4x wobulation respectively.
