Dynamic Motion Path Blur User Interface

摘要

Dynamic motion path blur techniques are described. In one or more implementations, paths may be specified to constrain a motion blur effect to be applied to a single image. A variety of different techniques may be employed as part of the motion blur effects, including use of curved blur kernel shapes, use of a mesh representation of blur kernel parameter fields to support real time output of the motion blur effect to an image, use of flash effects, blur kernel positioning to support centered or directional blurring, tapered exposure modeling, and null paths.

1. A method comprising:
displaying a path in a user interface of a computing device, the path input by a user through interaction with the user interface, in which:
the path is formed from a plurality of points, each of the points being selectable by a user through interaction with the user interface to modify the path; andthe path is configured to constrain a motion blur to be applied as a motion blur effect to an image; responsive to receipt of one or more inputs via the user interface involving movement of at least one point of the path from a first location to a second location in the user interface:
calculating the motion blur as part of the motion blur effect to transform the image by the computing device independently of a size of the image using the path in a domain separate from a domain of the image; andmodifying a display of the image in the user interface in real time by the computing device to include the calculated motion blur as part of the motion blur effect as the movement of the at least one point from the first location to the second location occurs.
