Abstract
A system and method for removing motion artifacts from an interlaced image is disclosed. The interlaced image comprises an odd and an even field. The system and method includes providing one of the odd and the even fields on every other line of the display and then providing a set of constant signal level lines to the remaining lines of the display. The method and system further includes shifting the location of the constant signal levels lines by a scan line responsive to a timing signal from the display, and providing the other of the odd and the even field to the display responsive to the shift.
Claims26
A system for removing artifacts caused during display of an interlaced image with motion, the interlaced image comprising an odd and an even field, the system comprising:
- means for providing one of the odd and the even fields on every other line of the display;
- means for providing a set of constant signal level lines to the remaining lines of the display;
- means responsive to a timing signal from the display for shifting the location of the constant level lines by a scan line;
- and
- means responsive to the shifting means for providing the other of the odd and the even field to the display.
A method for removing artifacts caused during display of an interlaced image with motion, the interlaced image comprising an odd and an even field, the method comprising the steps of:
- (a) providing one of the odd and the even fields on every other line of the display;
- (b) providing a set of constant level lines to the remaining lines of the display;
- (c) shifting the set of constant level lines by a scan line via a timing signal from the display;
- (d) increasing the brightness and color levels of video picture;
- and
- (e) providing the other of the odd and the even fields to the display.
