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.
Claims22
A method of forming an image of a moving object, comprising:
- capturing a first digital image of a moving object using a first rolling shutter scanning in a first direction;
- capturing a second digital image of the moving object using a second rolling shutter scanning in a second direction different from the first direction;
- and
- processing the first and second digital images to form a composite digital image of the moving image.
An imaging device, comprising:
- a pixel array having a plurality of rows and columns of pixels, each pixel including a photosensor;
- and
- a rolling shutter circuit operationally coupled to the pixel array, said shutter circuit being configured to capture a first image by sequentially reading out selected rows of integrated pixels in a first direction along the pixel array and a second image by sequentially reading out selected rows of integrated pixels in a second direction along the pixel array different from the first direction.
An image processing device, comprising:
- a digital image sensor having first and second rolling shutters configured to scan an image in different directions from one another;
- a processor configured to form a composite digital image from first and second images respectively captured using the first and second rolling shutters.
At least one computer-readable medium encoded with instructions which, when executed by a processor, performs a method including:
- receiving a first data stream representing a first digital image of a moving object captured using a first rolling shutter scanning in a first direction;
- receiving a second data stream representing a second digital image of the moving object captured using a second rolling shutter scanning in a second direction different from the first direction;
- and
- processing the first and second digital images to form a composite digital image of the moving image.
