1. A computer-implemented method for determining information about a scene of an image capture event, comprising: under the control of one or more computer systems configured with executable instructions, obtaining a first set of image data recorded during an image capture event by an image capture device collecting light in accordance with a first aperture characteristic; obtaining a second set of image data recorded during the image capture event by the image capture device collecting light in accordance with a second aperture characteristic different from the first aperture characteristic; detecting a first set of bokeh artifacts within the first set of image data; detecting a second set of bokeh artifacts within the second set of image data, the second set of bokeh artifacts having a correspondence to the first set of bokeh artifacts; determining motion blur information about the scene by analyzing the first set of bokeh artifacts and the second set of bokeh artifacts; and generating an image based at least in part on the motion blur information.
