METHOD AND SYSTEM FOR REPEATED FIELD DETECTION |
摘要 |
<p>A system and method for repeat field detection for use in rate conversion and video encoding of the type contemplated by the MPEG standards. Before encoding a frame, first field in the current frame is compared to the previously occurring field of the same parity. Next, a single number (the inter-field parameter) is generated, which is a measure of the difference between the two fields. If the inter-field parameter is below a threshold a signal is generated to indicate that the current field is a repeat of the previous field of the same parity. Otherwise, the signal is generated to indicate that the field is not a repeat of the previous field of the same parity (i.e. the field likely contains at least one small area of motion).</p> |
