- W1991968909 abstract "We have developed a real-time registration compensator for 1 Harpicon the Hi-Vision camera. Harpicon has the advantages of higher sensitivity and higher resolution than Saticon or Hi-Vision CCD imagers. However a camera with image pick-up tubes such as Harpicon produces registration errors which causes lower resolution and false color on objective edges. To solve this problem we developed a new method of detecting registration errors which is suitable for digital Hi-Vision cameras. The detector finds registration errors in the picture during the camera operation. This frees the operator from initial registration tuning and enables real-time compensation. Recently we developed a detection large scale integrated (LSI) circuit with a 1. 3tm complemental metal-oxide semi-conductor (CMOS) gate array and implemented the system in hardware. The detection hardware consists of two gate arrays twenty-four 256k x 4-bit FIFO memories and a small amount of control logic. The experimental hardware detects registration errors at 30 points (5 points vertically and 6 horizontally) in both R-G and B-G channels within 700 msec. The camera has a high resolution (40" @default.
