Video analyzer allows measuring by live video on the computer screen:
• | Instant brightness at the point under the mouse cursor; |
• | Image frequency (fields per second) under the mouse cursor; |
• | Average brightness of specified number of fields at the point under the mouse cursor; |
• | Root-mean-square noise amplitude by specified number of fields at the point under the mouse cursor. |
• | Signal to noise ratio of static images or live video on the monitor (Signal/noise tab). |
Live video could be obtained using any PC-based video capture system, IP camera software or by viewing video recordings.
Video analyzer could be used in many measurements, for example:
• | Calibration of filters and lenses for measuring camera sensitivity; |
• | Measuring spectral efficiency factors of light sources; |
• | Measuring frame rate, maximum signal/noise ratio and etc. |
To measure signal/noise ratio in measuring sensitivity you can also use the Image analyzer, which in measuring noise, analyzes multitude of pixels and has special tab for measuring signal/noise ratio.
