Method and apparatus for enhancing an incomplete, limited bandwidth picture generated by an image sensor
First Claim
1. In combination with a picture display device and an image sensor, said image sensor generating incomplete vertical bandwidth limited sequential image signals wherein each image signal comprises a plurality of alternate lines containing information, the lines interposed between said information containing lines being blanked, the method comprising the steps of:
- storing a first of said incomplete sequential image signals;
combining said first stored incomplete sequential image signal with the next incomplete sequential image signal to form a complete image signal, said complete image signal comprising alternate lines containing the information in said next incomplete sequential signal and the lines therebetween containing the information in said first of said incomplete sequential image signals; and
displaying said complete image signal on said display device.

Abstract
Apparatus for enhancing incomplete, limited bandwidth, sequential signals generated by an image sensor. Each of the incomplete signals comprises a plurality of alternate lines containing information, the lines interposed therebetween being blanked. A picture display device is also provided, and an intermediate storage device interposed between the image sensor and the display device. The storage device stores a first of the incomplete image signals and combines it with the next sequential image signal to form a complete image signal. The complete image sgnal, which is displayed on the display device, contains the information in the next incomplete image signal on alternate lines, the lines therebetween containing the information in the first incomplete image signal. The invention also constitutes a method for enhancing incomplete limited bandwidth sequential signals wherein a first of these signals is stored and then combined with the next sequential image signal to form the complete image signal.

2. Apparatus for enhancing incomplete vertical bandwidth limited image signals generated sequentially by an image sensor, each of said incomplete image signals having alternate lines containing information, the lines interposed therebetween being blanked, said apparatus comprising:
-
a picture display device; and an intermediate storage device interposed between said image sensor and said picture display device, said storage device storing a first of said incomplete image signals and combining said first image signal with the next of said incomplete image signals to form a complete image signal, said complete image signal comprising alternate lines containing the information in said next incomplete image signal and the lines therebetween containing the information in said first incomplete image signal. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)
