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.

Methods and apparatuses for facilitating generation images and editing of multiframe images

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.

Method and apparatus for illumination

The present invention relates to a method, a computer-readable medium, a computer program and apparatuses for removal of artifacts in flash images. Image data of a reference image captured using a first level of flash energy and image data of a main image captured using a second level of flash energy that is higher than said first level of flash energy is received. Image data of a third image is then determined based on said image data of said reference image and said image data of said main image, wherein said third image is a representation of said main image with removed artifacts.

Removal of artifacts in flash images

An image processing is applied in common to image data for a first image and to image data for a second image. The image data for the first image and the image data for the second image are moreover compared as a basis for matching a visual appearance of images for a stereoscopic presentation. The visual appearance can be matched in the current pair of images by adjusting at least one of the images accordingly and/or in future pairs of images by adjusting parameters of at least one of the image capturing components providing the image data.

Image processing for supporting a stereoscopic presentation

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.
