Abstract
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.
Claims20
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.
-20. (canceled)
An imaging system, comprising:
- a plurality of picture elements arranged in an array;
- and
- control circuitry configured to:
- capture light corresponding to a first image at a first exposure level with the plurality of picture elements in the picture element array;
- capture light corresponding to a second image at a second exposure level different than the first exposure level with the plurality of picture elements in the picture element array;
- convert the light captured by the plurality of picture elements for the first image to digital measurements;
- and
- convert light captured by the plurality of picture elements for the second image to digital measurements,
- wherein the control circuitry begins the capturing of the light corresponding to the second image at the second exposure level prior to the completion of the converting of the light captured for the first image to digital measurements,
- further wherein the control circuitry substantially completes the converting of the light for the first image to digital measurements prior to the beginning of the converting of the light for the second image to digital measurements.
-41. (canceled)
A method of obtaining image data using a digital imaging sensor, the method comprising:
- capturing a first image with the sensor at a first exposure level;
- capturing a second image with the sensor at a second exposure level different from the first exposure level;
- outputting the first image;
- and
- outputting the second image, wherein said capturing of the first image begins before said capturing of the second image begins, said capturing of the first image and said capturing of the second image overlap in time, and said outputting of the first image and said outputting of the second image do not overlap in time.
