Method and apparatus for displaying an enlarged image on multiple monitors to form a composite image

DETAILED DESCRIPTION What is claimed is: 1.
A method for displaying an image from video signals, comprising the steps of: generating video signals indicative of an interlaced image, said video signals containing video field data in two interlaced fields, each of said fields comprising successively occurring video line data; enlarging the image by replicating the video line data; determining where replications of the video line data of each of the interlaced fields would result in distortion between the two interlaced fields; providing a selected combination of video line data in place of the replications which would result in said distortion; and displaying the enlarged image on a plurality of monitors each having successively occurring scan lines so that each of the monitors displays at most a respective portion of the enlarged image which is less than an entirety of the enlarged image and so that a composite of each portion displayed on the monitors together constitute the enlarged image, the step of displaying including interlacing the successively occurring scan lines for each respective one of said monitors, forming display signals for the video line data including that which was replicated and that which was provided, and correlating said display signals with said scan lines for the monitors so that each monitor will display only the respective portion of the enlarged image.
2.
The method of claim 1 further comprising blanking the video line data which cause said distortion and filling in the blanked lines with said combination of video line data.
3.
The method of claim 1 wherein said step of forming signals comprises selecting scan lines of a given field for application to a delay device, then adding and averaging the output of said delay device and a selected other scan line of said given field, whereby the corresponding line on said display device contains information from two scan lines of said given field.
4.
The method of claim 1, further comprising writing said video signals into memory and sequentially reading video line data contained in the video signals from said memory that are in correspondence with at least portions of adjacent ones of said successively occurring scan lines of a respective one of said interlaced fields for producing said display signals
