OPERATING A DEVICE TO CAPTURE HIGH DYNAMIC RANGE IMAGES

摘要

Some embodiments provide a method of operating a device to capture an image of a high dynamic range (HDR) scene. Upon the device entering an HDR mode, the method captures and stores multiple images at a first image exposure level. Upon receiving a command to capture the HDR scene, the method captures a first image at a second image exposure level. The method selects a second image from the captured plurality of images. The method composites the first and second images to produce a composite image that captures the HDR scene. In some embodiments, the method captures multiple images at multiple different exposure levels.

主权项

1. A non-transitory machine readable medium of a device that captures images, the medium storing a program that when executed by at least one processing unit captures an image of a high dynamic range (HDR) scene, the program comprising sets of instructions for:
capturing and storing a plurality of images at a first exposure level; upon receiving a command to capture the HDR scene, capturing a first image at a second exposure level and a second image at a third exposure level; selecting a third image from the captured plurality of images; and compositing the first, second, and third images to produce a composite image that captures the HDR scene.
