Camera exposure optimization techniques that take camera and scene motion into account
First Claim
Patent Images
1. A method of controlling operation of an imaging device to capture data of a scene, comprising:
- monitoring motion within two or more images of the scene prior to its capture and relative to the imaging device, such that a quantity of relative motion is determined independent of another quantity of total motion that is separately monitored along each directional vector from a vector used for monitoring the relative motion within the two or more images of the scene, and wherein said separate monitoring of each directional vector provides a velocity and an acceleration of the total motion;
utilizing information from monitoring motion within the two or more images to calculate one or more exposure parameters including duration for use to capture data of each image; and
capturing data of the scene by use of the calculated one or more exposure parameters.

Abstract
Quantities of motion regarding an imaging device such as an electronic camera are calculated and used to adjust the exposure time and one or more other exposure parameters used to capture an image to improve the quality of the image. Motion blur caused by movement of the camera or by movement of an object within the scene being photographed is reduced by selecting appropriate exposure parameters. Further, when there is little or no motion detected, the exposure parameters may be selected to improve the depth of field and reduce the noise in the captured image.

12. An imaging device to capture data of a scene, comprising:
-
a photodetector; an optical system that projects light from the scene onto the photodetector; a processing unit that receives data of at least two images of the scene projected onto the photodetector and enables actions including; monitoring motion within two or more images of the scene prior to its capture and relative to the imaging device, such that a quantity of relative motion is determined independent of another quantity of total motion that is separately monitored along each directional vector from a vector used for monitoring the relative motion within the two or more images of the scene, and wherein said separate monitoring of each directional vector provides a velocity and an acceleration of the total motion; utilizing information from monitoring motion within the two or more images to calculate one or more exposure parameters including duration for use to capture data of each image; and capturing data of the scene by use of the calculated one or more exposure parameters. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A non-transitory processor readable storage media that includes a plurality of processor executable instructions for capturing data of a scene, wherein the execution of the instructions enables actions, comprising:
-
monitoring motion within two or more images of the scene prior to its capture and relative to the imaging device, such that a quantity of relative motion is determined independent of another quantity of total motion that is separately monitored along each directional vector from a vector used for monitoring the relative motion within the two or more images of the scene, and wherein said separate monitoring of each directional vector provides a velocity and an acceleration of the total motion; utilizing information from monitoring motion within the two or more images to calculate one or more exposure parameters including duration for use to capture data of each image; and capturing data of the scene by use of the calculated one or more exposure parameters. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
