Abstract
A device for motion estimation (100) includes a block characteristic measurement unit (110) configured to determine an image characteristic of a source block (210) of a reference frame (200). Motion of the source block (210) of the reference frame (200) with regard to a current frame is estimated by a motion estimation unit (120), wherein the motion of the source block (210) is estimated by either a motion estimation method other than phase correlation or by phase correlation depending on the image characteristic.

A device for motion estimation (100), comprising:
- a block characteristic measurement unit (110) configured to determine an image characteristic of a source block (210) of a reference frame (200);
- a motion estimation unit (120) configured to estimate motion of the source block (210) of the reference frame (200) with regard to a current frame (205), wherein the motion of the source block (210) is estimated depending on the image characteristic a) by a motion estimation method other than phase correlation or b) by phase correlation.
