Filed:

Aug 28, 2002

Appl. No.:

10/233106

Inventors:

Gregory M. Hunter - San Jose CA, US

Assignee:

Micron Technology, Inc. - Boise ID

International Classification:

G09G005/00

US Classification:

345611, 345428, 345581, 345582

Abstract:

A method and system for performing full-scene anti-aliasing for an image through a technique of rotating and unrotating rasterization of a scene and rendering a resulting image. A scene is rasterized at a first angle relative to a first coordinate system to generate a plurality of pixels, which are then applied to a polygon surface that is rendered at a second angle equal to the inverse of the first angle. Thus, the resulting image is re-oriented with respect to the first coordinate system.

Appl. No.:

11/700092

Assignee:

Aptina Imaging Corporation - Grand Caymans

International Classification:

H04N 9/64

US Classification:

348251, 348335, 348340, 3482221

Abstract:

Surface generation and positional gain adjustment techniques for an imager are described. Embodiments of the techniques use zones having flexible boundaries which can be reconfigured depending upon the type of lens being used in a given application. Each pixel within each zone is multiplied by a correction factor dependent upon the particular zone while the pixel is being read out from the array. The correction factors comprise coefficients that are different for each color channel and in some instances different for each corner of each color channel.

Appl. No.:

12/230310

Inventors:

Gregory M. Hunter - San Jose CA, US
Todd Sachs - Palo Alto CA, US

Assignee:

Micron Technology, Inc. - Boise ID

International Classification:

H04N 5/228

US Classification:

3482221, 3482181, 348262, 382284, 382294, 358450

Abstract:

A method and system for aiding user alignment of two or more partially overlapping digital images. A first image is captured. A portion of a first image is displayed with a preview of a portion of a second image. The second image is adjusted by movement of an used to capture the first image and generate the preview of the second image). Once satisfactory alignment is achieved, the second image is captured.

International Classification:

G06K 9/40

US Classification:

382275, 382255, 358 326

Abstract:

Methods, apparatuses and systems providing pixel correction values for a captured image, where the correction values are determined based on a piecewise-quadratic correction function in a first direction. The parameters for the piecewise-quadratic correction function in the first direction are calculated based on a plurality of piecewise-quadratic correction functions in a second direction. The correction values may be positional gain adjustment values.
