Abstract:
A method of performing motion search for video including providing at least one motion search offset range for multiple search range scale levels and resolution levels, monitoring at least one operating metric, selecting a search range scale level, and performing motion search for selected resolution levels using search windows determined by the offset ranges at the selected search range scale level. A video encoder including a memory for storing motion search offset ranges for multiple resolution levels and multiple levels of a search range scale, and control logic for controlling motion estimation. The control logic monitors at least one operating metric, selects a search range scale level, and controls motion search at selected resolution levels using search windows determined by the offset ranges at the selected search range scale level. The offset range and resolution levels may be modified based on the operating metrics and/or motion search comparison metrics.
