Abstract: The specification and drawings present a new method, apparatus and software product for enhancing a dynamic range of an image with a multi-exposure pixel pattern taken by an image sensor of a camera for one or more color channels, wherein a plurality of groups of pixels of the image sensor have different exposure times (e.g., pre-selected or adjusted by a user through a user interface using a viewfinder feedback, or adjusted by a user through a user interface after taking and storing RAW image, etc.). Processing of the captured image for constructing an enhanced image of the image for each of the one or more color channels can be performed using weighted combination of exposure times of pixels having different pre-selected exposure times according to a predetermined criterion.

In the method degradation information of each color component of the image is found and is used for obtaining a degradation function. Each color component is restored by said degradation function. The image is unprocessed image data, and the degradation information of each color component can be found by a point-spread function. The invention also relates to a device, to a module, to a system and to a computer program product and to a program module.

Abstract: 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 (?) 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 (?) associated with the digital imaging sensor.

Abstract: A method and an related apparatus for performing a white balance operation on an image with pixels, wherein global colour gain values common for substantially all pixels of the image are first determined. Then local colour gain values for individual pixels of the image are determined based on analyses of a local window comprising said individual pixel and a number of adjacent pixels. Thereafter, final colour gain values for individual pixels of the image are determined as a weighted average of the global and the local colour gain values, and a white balance operation is performed on the image using the final colour gain values.

Abstract: A system and method for enabling improved zoom control during the playback of a video. In various embodiments, a video player includes an improved dynamic user interface which UI enables a user to zoom into high resolution images whenever the “pause” button is pressed on the video player. Various embodiments also provide for the use of improved algorithms for image interpolation. These algorithms involve the utilization of a sequence of adjacent video frames so that the spatial resolution of the current frame can be enhanced. These algorithms may also at least selectively take advantage of high-resolution still images that exist in media content containing merged video and still images.

Abstract: A motion estimation process in video coding takes into account the estimates in the immediate spatio-temporal neighborhood, through an adaptive filtering mechanism, in order to produce a smooth and coherent optical flow field at each pixel position. The adaptive filtering mechanism includes a recursive LMS filter based on pixel-wise algorithm for obtaining motion vectors in a reference image of a video image frame, while consecutively scanning through individual pixels of the image frame. This motion estimation process is particularly well suited for the estimation of small displacements within consecutive video frames, and can be applied in several applications such as super-resolution, stabilization, denoising of video sequences. The method is also well suited for high frame rate video capture.
