    Abstract: A method for motion estimation in video image data comprises a step of providing a block of pixels (B(F(t))) of a current image (F(t)) and a block of pixels (B(F(t-1))) of a previous image (F(t-1)) and a block of pixels (B(F(t-2))) of a pre- previous image (F(t-2)). A reconstructed block of pixels (B*(F(t), F(t-2),v)) is determined by combining the block of pixels of the previous image (B(F(t-1),v) and the block of pixels of the pre-previous image B(F(t-2),v)). A motion vector (v) of the block of pixels of the current image (B(F(t))) is evaluated by comparing the block of pixels of the current image (B(F(t))) with the reconstructed block of pixels (B*(F(t), F(t-2),v)).

    Abstract: A method and system is provided for reducing mosquito noise in a digital image. The method and system receives an input luminance value for a first pixel in the digital image, and determines whether the first pixel is in relative close proximity to an object appearing in the digital image, based on a comparison of the variation between the input luminance value for the first pixel and luminance values of a first plurality of neighboring pixels. If the first pixel is in relative close proximity to an object, the method performs an average filtering of the input luminance value for the first pixel, based on the luminance values of a second plurality of neighboring pixels, to provide a filtered luminance value for the first pixel.

    Abstract: A method and system for frame insertion in a digital display system is provided. The method is adapted for use with a liquid crystal display (LCD) type display and is effective to substantially reduce motion blur. The LCD display receives a sequence of digitized input frames at a first frequency. The method generates a sequence of output frames that include the digitized input frames interspersed with a plurality of modified frames. Each of the modified frames is substantially similar to a preceding digitized input frame, but has a reduced luminance. The modified frames may be generated by multiplying a preceding digitized input frame by a reduced luminance factor. The reduced luminance factor may be determined as a fixed value or as a function of an average pixel level of a preceding frame.

    Abstract: A user interface on a three-dimensional display overcomes unsettling effects that arise when user interfaces are presented to users in a three-dimensional context. An extended border defines an extended portion of a background of the user interface. If the background is opaque, the extended portion of the background is blended with the underlying video or image. If the background is semi-transparent, user interface content is presented as appearing to project out of the screen, and the extended portion of the background is blended with the underlying video or image with variable blending alpha. If the background is transparent, user interface content is presented as appearing to project out of the screen, the video or image underlying the original background of the user interface is blurred, and the portion of the video or image underlying the extended portion of the background is blurred with variable blur radius.

    Abstract: An image creation method uses first and second images which comprise 2D views of a 3D scene from different viewpoints. The images are combined to derive a third image representing a 2D view of the 3D scene from a third viewpoint, with greater pixel resolution than the pixel resolution of the first and second images. This method uses the fact that the stereo images are closely related, to enable construction from the two images of a third image of higher resolution. This third image can then be provided as a single higher resolution 2D image, or else the third image can be used to enhance one of the original stereo 2D images.

    Abstract: A method of reducing mosquito noise in a digital image. As mosquito noise is often most plainly visible in the "background" of an image (e.g., the sky or some other backdrop to objects within an image), the luminance value of the background of the image is first determined. Then, the luminances of the pixels of the image are compared against this "background luminance" to determine which should be considered as part of this background. The luminances of these background pixels are then averaged so as to smooth out the representation of the background, and reduce mosquito noise.
