抄録

The development of the Marathon image processing system which measures step frequency and automatically controls the camera by processing the image through the Marathon program is discussed. Rather than use a special image, this system processes the ordinary camera shot which can be broadcast. The image processes used for this purpose are bi-level quantize, area calculation, detection of a motion vector, chromakey, compress, expand and FFT. Some improvements were made to the motion vector process. These were implemented with the realtime image processing system-Picot system. Using the flexibility and generality of the Picot system, various processes have been developed very rapidly and effectively. Comparisons are drawn between general purpose software oriented system (Picot) and special purpose hardware oriented systems.
