HIGH DYNAMIC RANGE VIDEO

摘要

Certain cameras and systems described herein produce enhanced dynamic range still or video images. The images can also have controlled or reduced motion artifacts. Moreover, the cameras and systems in some cases allow the dynamic range and/or motion artifacts to be tuned to achieve a desired cinematic effect.

1. A method of obtaining image data using a digital imaging sensor comprising a picture element array of rows and columns, the method comprising:
using a plurality of picture elements in the picture element array to capture light corresponding to a first image at a first exposure level; using the plurality of picture elements in the picture element array to capture light corresponding to a second image at a second exposure level different than the first exposure level; converting the light captured by the plurality of picture elements for the first image to digital measurements; and converting the light captured by the plurality of picture elements for the second image to digital measurements, wherein the step of using the plurality of picture elements in the picture element array to capture light corresponding to the second image at the second exposure level begins prior to the completion of the step of converting the light captured by the plurality of picture elements for the first image to digital measurements, further wherein the step of converting the light captured by the plurality of picture elements for the first image to digital measurements substantially completes prior to the beginning of the step of converting light captured by the plurality of picture elements for the second image to digital measurements.
