Abstract: Systems and methods of defending and/or guarding against inadvertent actuation of a virtual button upon a touch sensitive screen and/or device. A virtual button may be a touch sensor, set of touch sensors and/or touch areas upon a touch screen—the actuation of which may be associated with the execution of a process. In one embodiment, a virtual button may comprise a first touch area and a second guarding area. Certain touches and other conditions within the first touch area and/or second guarding area may be interpreted by the device as either intentional or inadvertent. If the touches are interpreted as inadvertent, then the process associated with the virtual button may be suppressed.

Abstract: Digital imaging systems, articles of manufacture, and digital image processing methods are described. According to one aspect, a digital imaging system includes an imaging system configured to provide image data of an image, the image data comprising digital image data for a plurality of pixel locations and processing circuitry configured to process the image data provided by the imaging system to denoise and sharpen the image data, wherein the processing circuitry, for an individual one of the pixel locations, is configured to identify a respective subset of the image data corresponding to the one pixel location and perform a single processing operation using the image data of the identified subset of the image data to denoise and sharpen the image data of the individual one pixel location.

Abstract: Digital image processing methods, digital image devices and articles of manufacture are described. According to one aspect, a digital image processing method includes providing digital image data of a plurality of colors of an image, wherein the image data comprises a plurality of sets individually comprising mosaic data of one of a plurality of colors at a plurality of pixel locations, analyzing image data of one of the pixel locations with respect to image data of another of the pixel locations, and adjusting the image data of the one pixel location responsive to the analyzing, wherein the adjusting comprises adjusting to one of denoise the image data and sharpen the image data.

Abstract: An electronic device that performs automatic red-eye correction on digital images includes a user-adjustable threshold, enabling the user to adjust the sensitivity of the automatic red-eye-correction algorithm dynamically while viewing marked candidate red-eye locations in a digital image. Such dynamic adjustment of the threshold facilitates the rejection of false positives while reducing the number of input gestures required of the user.

Abstract: A device that performs automatic red-eye correction on a digital image saves the original image data and a location indicator from each portion of the digital image on which red-eye correction is performed to facilitate the subsequent undoing of red-eye correction. Red-eye correction may be undone at any time after red-eye correction has been performed by replacing the corrected image data with the original image data that is stored with the corrected digital image, and the device on which red-eye correction is undone may be distinct from the device that captured the digital image and from the device that performed red-eye correction on the digital image.

Abstract: When using a strobe in capturing a digital image is determined to be imminent, a pre-capture image may be saved from which iris-color information can be derived. The iris-color information derived from the pre-capture image may be used to improve red-eye correction of the captured digital image.

Abstract: Auto-focus in a digital camera is improved by stabilizing successive images. Each auto-focus image is correlated to previous images so that scene movement or motion can be tracked. The area in the scene where focus figure-of-merit is computed is adjusted according to the amount of scene movement. Also, two separate focus frames may be compared to determine the direction and speed of the motion. This improves the accuracy of the focus figure-of-merit which results in fewer autofocus failures.

Abstract: Image stabilization systems and methods are disclosed. One embodiment of the image stabilization method, among others, includes detecting motion of a camera, and responsive to the detected motion, changing an optical filter orientation to displace an image provided on a sensor.

Abstract: Image-exposure systems and methods are disclosed. One embodiment of the system includes a motion detecting device, and logic configured to determine when to terminate an image-exposure based on detected motion of a camera.

Abstract: A user interface for red-eye removal allows a user selectively to accept or reject red-eye removal in candidate red-eye regions that are automatically detected in a digital image and presented to the user. A modified digital image may be produced and saved in which red-eye removal is performed in the candidate red-eye regions the user accepts.
