Disclosed herein is an apparatus. The apparatus includes a housing, electronic circuitry, and an audio-visual source tracking system. The electronic circuitry is in the housing. The audio-visual source tracking system includes a first video camera and an array of microphones. The first video camera and the array of microphones are attached to the housing. The audio-visual source tracking system is configured to receive video information from the first video camera. The audio-visual source tracking system is configured to capture audio information from the array of microphones at least partially in response to the video information. The audio-visual source tracking system might include a second video camera that is attached to the housing, wherein the first and second video cameras together estimate the beam orientation of the array of microphones.

Methods and apparatuses are provided for facilitating generation and editing of multiframe images. A method may include grouping a plurality of images into one or more groups of images. Each group of images may comprise a plurality of images depicting a common scene. The method may further include determining a reference image for at least one of the one or more groups of images. Each reference image may be associated with a respective group for which it was determined. The method may additionally include causing at least one reference image to be displayed to a user such that the user is enabled to select a displayed reference image to enhance using multiframe image processing to generate a multiframe image from a plurality of images from the group of images with which the selected displayed reference image is associated. Corresponding apparatuses are also provided.

In accordance with an example embodiment of the present invention, an apparatus comprises a light source capable of illuminating a target scene and an adjustable light filter coupled with the light source, the adjustable light filter adapted to display a filter image, the filter image created to spatially filter the illumination based at least in part on at least one parameter.

An improved system and method for capturing an image using a camera or a camera module. In the present invention, the number of image shots taken, as well as the integration time of each image shot, are controlled based upon knowledge about the existence or absence of camera motion. Whenever a motion is detected above a predetermined motion threshold, the integration phase of the current image shot ends, and the integration of the next image shot begins. The present invention therefore adapts to the actual camera motion during exposure. If there is no camera motion, a single, long exposed image shot is captured. If there is camera motion, the total exposure time is divided between multiple shots in accordance with the degree of camera motion.

An apparatus for providing a camera barcode reader includes a processing element configured to process an input image for an attempt to decode the input image using a current barcode reading method, to determine whether the processing of the input image is successful, to switch to one of a different barcode reading method or processing a new frame of the input image using the current barcode reading method in response to the processing of the input image being unsuccessful, to attempt a decode of the input image using the current barcode reading method in response to the processing of the input image being successful, and to perform a switch to the different barcode reading method in response to a failure of the attempt to decode the input image using the first barcode reading method.

Methods and systems are provided for adjusting the contrast and intensity of digital images. Digital images may be processed by first creating a histogram that identifies the intensity of components of the digital image. A transformation function is then computed using the histogram. The transformation function can be used to adjust the intensity of a low light portion of the digital image and is applied to individual color components of the digital image. Finally, the contrast of a portion of the digital image other than the low light portion of the digital image is adjusted.

Adaptive contrast optimization of digital color images

An apparatus, method, mobile station and computer program product are provided for filtering noise from a digital signal. In particular, a signal-dependent noise model is used that provides the pointwise (or pixelwise) standard deviation of the temporal noise of raw data outputted from a digital imaging sensor as a function of the image intensity. In addition, unlike conventional noise models, the standard deviation of the noise (&#x3c3;) is a parameterized function, where the parameters are key characteristics of the digital imaging sensor. These parameters may include, for example, the pedestal level (p), the quantum efficiency (q), and the analogue gain (&#x3b1;) associated with the digital imaging sensor.

For binarizing an image, which is composed of pixels, the image is split into two semi-images. Local parameters are initialized based on values of pixels that lie in an area adjacent to a boundary separating the semi-images. A binarization is then performed separately for each of the semi-images using an adaptive threshold, wherein the adaptive threshold is calculated for each of the semi-images proceeding from the initialized local parameters.

A method and associated device wherein an inverse histogram based pixel mapping step is combined with an edge enhancement step such as unsharp masking. In such an arrangement the inverse histogram based pixel mapping step improves the performance of the unsharp masking step, serving to minimize the enhancement of noise components while desired signal components are sharpened.
