    "abstract": "The performance abilities of the recently-developed 3-tube color camera are advancing year by year. Its development requires new methods of evaluation. For example, warm-up time is a very important parameter for the recent battery supplied ENG camera. This time evaluation requires much precise data concerning color balance and registration error from various points in the picture within short time intervals. The conventional methods of using osciloscopes and photographs is now inadequate for meeting these requirements.",
