Digital imager with dual rolling shutters
First Claim
Patent Images
1. A method of forming an image of a moving object, comprising:
- capturing a first digital image of the moving object within a scene using a first rolling shutter scanning in a first direction across a portion of the scene at a first sweep speed;
capturing a second digital image of the moving object within the scene using a second rolling shutter scanning in a second direction across the portion of the scene at a second sweep speed, the second direction different from the first direction;
processing the first and second digital images to form a composite digital image of the moving image using the first sweep speed and the second sweep speed; and
capturing a third digital image of the moving object using a third rolling shutter scanning in a third direction different from the first and second directions.

Abstract
A method of forming an image of a moving object is provided. The method includes capturing a first digital image of a moving object using a first rolling shutter scanning in a first direction. Likewise, a second digital image of the moving object is captured using a second rolling shutter scanning in a second direction different from the first direction. The first and second digital images are processed to form a composite digital image of the moving image.

9. An image processing device, comprising:
-
a digital image sensor having first and second rolling shutters configured to scan a portion of an image in a first direction using the first rolling shutter at a first sweep speed and to scan the portion of the image and in a second direction, different from the first direction, using the second rolling shutter at a second sweep speed; and a processor configured to form a composite digital image from first and second images respectively captured using the first and second rolling shutters and to process the composite digital image using the first sweep speed and the second sweep speed, wherein the digital image sensor includes at least a third rolling shutter that is configured to scan the image in a direction different from the first and second rolling shutters. - View Dependent Claims (10, 11, 12, 13)

14. A non-transitory computer-readable medium encoded with instructions which, when executed by a processor, performs a method including:
-
capturing a first digital image of the moving object within a scene using a first rolling shutter scanning in a first direction across a portion of the scene at a first sweep speed; capturing a second digital image of the moving object within the scene using a second rolling shutter scanning in a second direction across the portion of the scene at a second sweep speed, the second direction different from the first direction; processing the first and second digital images to form a composite digital image of the moving image using the first sweep speed and the second sweep speed; and capturing a third digital image of the moving object using a third rolling shutter scanning in a third direction different from the first and second directions. - View Dependent Claims (15)
