Abstract

High frequency interstitial point generation by Two Dimensional Convolute Integer Technology leads to enhanced resolution for large screen television, i.e., three gun display monitors. The high frequency interstitial points generate a high frequency interstitial image, which is interlaced with the real image, doubling the number of horizontal lines on the monitor. A side-by-side comparison of a number of images, interstitial and real will be presented. The interstitial image is 100 calculated data. The real data is from a video camera/frame grabber digitizer. The real and interstitial images are 512 pixels per row and 480 rows, allowing a resolution enhanced image of 960 rows with 512 pixels per row. The high frequency nature of the interstitial image is the result of applying a high frequency Two Dimensional Convolute Integer Operator, 8 X 8 mask 6 Dimensional Convolute Integer Operators with mask sized up to 14 X 14 and surface orders 12 and 13 have been developed. The larger mask size, higher surface order Operators have higher frequency response characteristics. The higher the frequency response of the Operator, the higher the resolution, or fine line detail, in the interstitial image.
