H01L 31/0232

US Classification:

257432, 257E31127

Abstract:

Methods and apparatuses providing color filter patterns arranged to reduce cross talk in image signals. The apparatuses include an array of pixels, each pixel having an associated color filter, arranged such that cross-talk is distributed among pixel signals of each color of the color filters.

International Classification:

G06K 9/00

US Classification:

382103

Abstract:

A method of scanning a scene using an image sensor includes (a) dividing the scene into multiple first portions; and scanning a first portion for presence of objects in an object class. The method further includes continuing the scanning of the multiple first portions for presence of other objects in the scene. The method also selects a second portion of the scene, in response to detecting an object in the first portion; and then tracking the object in the selected second portion. The second portion of the scene is selected based on estimating motion of the object detected in the first portion, so that it may still be located in the second portion.

International Classification:

H04N 13/02
G06T 5/00

US Classification:

348 47, 382154, 348E13074

Abstract:

A system of stereo imagers, including image processing units and methods of blurring an image, is presented. The image is received from an image sensor. For each pixel of the image, a depth filter component is determined based on a focal area of the image and a depth map associated with the image. For each pixel of the image, a trilateral filter is generated that includes a spatial filter component, a range filter component and the depth filter component. The respective trilateral filter is applied to corresponding pixels of the image to blur the image outside of the focal area. A refocus area or position may be determined by imaging geometry or may be selected manually via a user interface.

Appl. No.:

13/760569

Inventors:

David R. Pope - Fremont CA, US

Assignee:

Aptina Imaging Corporation - George Town

International Classification:

G06T 5/00
H04N 13/02

US Classification:

348 46, 382255

Abstract:

An electronic device may have a camera module. The camera module may capture images having an initial depth of field. The electronic device may receive user input selecting a focal plane and an effective f-stop for use in producing a modified image with a reduced depth of field. The electronic device may include image processing circuitry that selectively blurs various regions of a captured image, with each region being blurred to an amount that varies with distance to the user selected focal plane and in response to the user selected effective f-stop (e.g., a user selected level of depth of field).

Inventors:

David Pope - Fremont CA, US

Assignee:

Aptina Imaging Corporation - George Town

International Classification:

G06F 1/32

US Classification:

382103

Abstract:

Systems and methods are provided for presence detection using an image system. The image system may be a camera that is integrated into an electronic device. In some embodiments, the image system can accommodate multiple operating modes of the electronic device. For example, when the electronic device is operating in a normal power mode, control circuitry of the image system can detect when a user has left and is no longer using the electronic device. When the electronic device is operating in a power saving mode, the control circuitry can detect user presence (e.g., when a user has come back to the electronic device). In some embodiments, the control circuitry can adjust for both gradual and sudden light changes.

Appl. No.:

8/484704

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

G06F 1100

US Classification:

39518507

Abstract:

Errors in data stored in the memory of a computer are detected prior to use of the data. A protected data type is declared in writing a program in which errors in critical data must be detected before the data are used. The invention is preferably implemented on a personal computer system (10) or in a microcontroller for a device. When a protected data item is initialized, both the protected data item and its corresponding bit-inverted form are stored in memory. A constructor function is used to determine the bit-inverted form. Any time that the protected data item is subsequently accessed for use by an application program, either the stored protected data item or its corresponding bit-inverted form are inverted for comparison to the other stored data item. Any difference detected in this comparison indicates that a change has occurred in either or both of the protected data item and its corresponding bit-inverted form within memory. Depending upon the application program in which the invention is used, an appropriate action is taken upon detecting such an error, such as providing an indication of the error and terminating further execution of the program.

David R. Pope - Fremont CA, US

International Classification:

H04N 9/04
G06T 5/00
H04N 5/367
H04N 9/64

Abstract:

Embodiments relate to lateral chromatic aberration (LCA) recovery of raw image data generated by image sensors. A chromatic aberration recovery circuit performs chromatic aberration recovery on the raw image data to correct the resulting LCA in the full color images using pre-calculated offset values of a subset of colors of pixels.
