Processing graphics data for display on a stereoscopic display. In one example embodiment, a method of processing graphics data for display on a stereoscopic display includes several acts. First, a first projection matrix call from a graphics application to a graphics library is intercepted. Next, it is determined that the first projection matrix call produces a perspective projection matrix. Then, the first projection matrix call is forwarded to the graphics library. Next, a first drawing call with a first viewpoint from the graphics application to the graphics library is intercepted. Then, a second drawing call with a second viewpoint is generated. Next, a third drawing call with a third viewpoint is generated. Finally, the second and third drawing calls are forwarded to the graphics library.

A method of converting an input color codeword from a first color format to a second color format comprises providing a reference format having reference bit positions and comparing the first bit positions associated with the first color format to the reference bit positions. Second bit positions associated with the second color format are compared to the reference bit positions. The relative bit position shifts based on the compared first bit positions and the compared second bit positions are determined. Format conversion bit masks are then generated based on the first and second color formats and the determined relative bit position shifts. The input color codeword is converted to the second color format based on the format conversion bit masks and the relative bit position shifts.

A method of generating a high-resolution image from a set of source low-resolution images includes estimating a high-resolution image based on the set of source low-resolution images. The estimated high-resolution image is then transformed into a set of estimated low-resolution images. The set of source low-resolution images is compared with the set of estimated low-resolution images to generate a set of low-resolution errors. The set of low-resolution errors is transfomed into a set of high-resolution errors. A high-resolution error image based on the set of high-resolution errors is generated. The high-resolution error image is combined with the estimated high resolution image to yield an updated estimated high-resolution. The above steps are repeated until the updated estimated high-resolution image is of a desired quality.

A system and method of editing a digital image to remove an unwanted object includes designating a rectangular region of the digital image including a subset of pixels within the digital image that includes the object to be removed. A band of pixels adjacent one major side of the rectangular region is selected and a mirror of the selected band of pixels is copied in a repeating pattern to define a first matrix corresponding in size to the designated region. A band of pixels adjacent the opposite major side of the rectangular region is then selected and a mirror of the selected band of pixels is copied in a repeating pattern to define a second pixel matrix corresponding in size to the designated region. The pixels of the first and second matrices are blended according to a first blending equation to create an initial texture. A band of pixels adjacent one minor side of the rectangular region is then selected and a mirror of the selected band of pixels is blended with a band pixels of similar width in the initial texture that extends along the one minor side. A band of pixels adjacent the other minor side of the rectangular region is then selected and a mirror of the selected band of pixels is blended with a band of pixels of similar width in the initial texture that extends along the other minor side thereby to complete the texture. The pixels within the designated region are replaced with the texture thereby to remove the object from the digital image.

An apparatus for expanding a source pixel in a digital image includes an edge direction detector detecting edge direction in the vicinity of the source pixel. An interpolator interpolates multiple sets of pixels in a region surrounding the source pixel in the detected edge direction to generate a set of output pixels representing an expansion of the source pixel. Methods and computer programs for expanding a source pixel in a digital image are also provided.
