Abstract
A video analyzer measures and outputs a visual indication of a dynamic range of a video signal. The video analyzer includes a video input to receive the video signal and a cumulative distribution function generator generates a cumulative distribution function curve from a component of the video signal. A feature detector generates one or more feature vectors from the cumulative distribution function curve and a video dynamic range generator produces a visual output indicating a luminance of one or more portions of the video signal.
Claims20
A video analyzer for measuring dynamic range of a video signal, comprising:
- a video input structured to receive the video signal;
- a cumulative distribution function generator structured to generate a cumulative distribution function curve from a component of the video signal;
- a feature detector structured to generate one or more feature vectors from the cumulative distribution function curve;
- and
- a video dynamic range generator structured to produce a visual output indicating a luminance of one or more portions of the video signal based on the one or more feature vectors.
A method for measuring dynamic range of a video signal, comprising:
- generating a cumulative distribution function curve from a component of the video signal;
- generating one or more feature vectors from the cumulative distribution function curve;
- and
- producing a visual output indicating a luminance of one or more portions of the video signal based on the one or more feature vectors.
One or more computer storage media comprising instructions, which, when executed by one or more processors of a video analyzer, cause the video analyzer to:
- generate a cumulative distribution function curve from a component of the video signal;
- produce one or more feature vectors from the cumulative distribution function curve;
- and
- generate a visual output indicating a luminance of one or more portions of the video signal based on the one or more feature vectors.
