Abstract: A method for changing the color of teeth in a digital image is disclosed herein. An embodiment of the method comprises locating the position of a mouth region in the digital image; defining a correction zone associated with the mouth region; calculating the probability that at least one pixel in the correction zone represents a tooth; and changing the color of the at least one pixel by an amount that is proportional to the probability.

Abstract: A digital imaging device having a CCD sensor array with one or more fields captures both short and long exposures of a particular field during the capture of a single image frame. The short-exposure image data and the long-exposure image data from the particular field may be correlated to estimate motion within the image frame.

Abstract: Hydrocarbon solids are removed from an oil well by feeding into the oil well a composition comprising at least 40 vol. % dense phase carbon dioxide and at least 30 vol. % of a C1–C3 alkanol component and optionally one or more surfactants, under a pressure of 300 to 10,000 psia and a temperature of 90° F. to 120° F., holding the composition in the well to solubilize hydrocarbon solids, and then removing from the well a liquid composition comprising solubilized hydrocarbon solids and alkanol.

Abstract: When a digital camera detects that it has been placed in a demo dock, it resets internal settings to demo defaults and may launch a point-of-purchase dock demo to attract attention. When a customer removes the camera from the demo dock, an interactive demo may begin. The demo may instruct the customer how to interact with the demo or end it. Once ended, the camera reverts to normal operation until replaced in the demo dock. Methods of using the dock and digital camera are also disclosed.

Abstract: The shutter of a digital imaging device may be calibrated by comparing a characteristic of two separate exposures obtained from a single field of the device's imaging sensor during a single exposure cycle. Calibrating the shutter in this manner facilitates the accuracy of even very short exposure times.

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 digital imaging device having a CCD sensor array with one or more fields captures both short and long exposures of a particular field during the capture of a single image frame. The short-exposure image data and the long-exposure image data from the particular field may be correlated to estimate motion within the image frame.

Abstract: A digital imaging device having a CCD sensor array with at least one field captures both short and long exposures of a particular field during the capture of a single image frame, the short-exposure image data from the particular field being used to extend the dynamic range of clipped pixel data.

Abstract: An interactive three-dimensional virtual-reality photo gallery containing pictures taken by a user is displayed on a display of a digital camera 10. The user navigates through the gallery using camera buttons. Methods relating to implementing the virtual-reality photo gallery are also disclosed.

Abstract: A method and device for adjusting white balance are disclosed herein. The method may comprise generating data representative of an image with and without the use of a strobe. The contribution of the strobe and the contribution of ambient light are on the data are calculated. Based, in part, on the contributions of the ambient light and the strobe, a weight is calculated. The weight is applied to the data in order to adjust the white balance.

Abstract: Autofocus methods and digital cameras employing a holographic element or hologram. The holographic element generates one or more displaced images that are processed to generate a bipolar contrast signal that provides for improved autofocus performance of the digital 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.

Abstract: Disclosed are a digital camera and methods for managing images captured by the digital camera. A method implemented by a digital camera, comprising the steps of receiving a first user input corresponding to an image displayed by a digital camera; converting a first set of data corresponding to the image to a second set of data responsive to the first user input, wherein the second set of data is smaller than the first set of data; and storing the second set of data in non-volatile memory.

Abstract: The present invention provides a system and method for compensating captured images. Briefly described, one embodiment comprises white balance compensating a strobed image data and a nonstrobed image data using a first white balance compensation value corresponding to supplemental illumination provided by a supplemental illumination source, determining a difference between the strobed image data compensated with the first white balance compensation value and the nonstrobed image data compensated with the first white balance compensation value, white balance compensating the nonstrobed image data using a second white balance compensation value corresponding to ambient light, and combining the difference to the nonstrobed image white balance compensated using the second white balance compensation value.

Abstract: A smart charger that includes a housing with an interface for power and data transmission and adapted for connection to a communication device, with a second interface adapted for connection to a power source, and with a third interface adapted for connection to a second communication device. A charger within the housing is connected to the second interface to receive power, and connected to the first interface to provide charging power. A control module within the housing provides for communication between the first interface and the third interface.
