NEW VIDEO CAMERA MEASUREMENT TECHNOLOGY
FM Systems, Inc. announced a new concept in video camera performance measurement using a hand-held, battery operated meter with a digital display. The CM-1 CAMERA MASTER measures Sync amplitude, Luminance (iris setting), Composite video amplitude, Color Burst amplitude (for color cameras), and lens Focus measurement.
Lens Focus is accomplished by displaying picture pixel content so that the Focus ring is adjusted for a maximum reading of whatever scene the camera is aimed at. Back Focus adjustment uses the same principle by placing the camera a known distance from a target, setting the lens to the same distance, and then adjusting the Back Focus to the highest reading. This insures that the lens system is correctly matched to the camera.
The Sync amplitude measurement enables the condition of the coaxial cable and monitor termination to be determined. Open and shorted cables can be instantly identified as well as intermittent connections and defective terminations. Even double terminations can be detected. These tests can be performed at the camera or at the monitor location.
Luminance measurement enables accurate setting of the manual Iris and also to proof-test the range of operation of an Auto- Iris control system. This measurement can prove that a given Auto-Iris will automatically adjust to the range of lighting conditions that can occur. The Luminance measurement can not only measure maximum White, but also can measure Black Level by capping the lens.
The Composite video setting measures the peak-to-peak video signal to insure that all cameras deliver the standard 1 Volt Peak-to-Peak video signal for consistent picture for each camera.
Color Burst measurement is vital for best performance of color cameras. This test, combined with the Sync measurement, insures that the system is delivering the Luminance-to-Chrominance ratio necessary for best color reproduction. This test is performed when adjusting Cable Equalizers to correct setting.
This meter can be carried in a pocket to the camera. It can be read in full day light and the test result is digitally displayed so that the result is unambiguous and does not require interpretation by the user.
