Cinematic image blur in digital cameras based on exposure timing manipulation

摘要

Cinematic motion blur and other cinematic effects are enabled during image capture through exposure timing manipulation. The resulting captured images and videos include one or more cinematic effects without the need for a user to impose the cinematic effects post-capture.

主权项

1. A method for generating cinematic blur in a digital camera, the method comprising:
accessing a cinematic effect comprising a total exposure time for a digital image sensor of the digital camera and an effective exposure time; generating a pulse pattern for the image sensor comprising a plurality of pulse durations such that consecutive pulse durations are separated by non-zero spacing durations, the sum of the plurality of pulse durations substantially equal to the total exposure time and the sum of the plurality of pulse durations and spacing durations being substantially equal to or less than the effective exposure time; applying the generated pulse pattern to the image sensor; capturing, by the image sensor, image information representative of light incident upon the image sensor, the image information representative of light incident upon the image sensor during the pulse durations and not representative of light incident upon the image sensor during the spacing durations; and storing the captured image information.
