ABSTRACT:
A method for the automatic detection of fields or frames in film or video content having similar or substantially the same luminance or color component values, for example to detect black frames. Image sample values are assigned to a sample value range having a signed weight associated therewith, and a contribution to a discriminator function is determined for each sample range depending on the signed weight and the number of input samples in the sample value range. The discriminator function output is then compared with a threshold.
