Abstract: An output rescale module may determine an estimated set of lines to hold in vertical support for use when performing image transformations. For example, an output rescale module may monitor input Y coordinates (in terms of input pixel lines) computed over previous lines and compute a set of lines to hold in a set of line buffers. As each output pixel line is generated, the output rescale module may compute the minimum and maximum values of Y generated by the transform across that line. The minimum and maximum input Y coordinates may then be averaged to determine the center value (the centermost input line) for that output line. The difference (in terms of input pixel lines) between centerlines for two adjacent output lines may be added to the centerline value for the current output line to estimate a center line for the next (not yet generated) output pixel line.

Abstract: Embodiments of the present disclosure generally relate to image signal processing logic, and in particular, to separating an undecimated image signal data to create two components with lower resolution and full-resolution, generating an interpolation guidance information based on the two components created by separation, forming a difference image data representing the difference between the chroma and luma values of each pixel and its neighboring pixels, and merging the processed image data from the processing pipelines with the unprocessed image data using the interpolation guidance information generated. The generation of the interpolation guidance information is based on determining distances between pixel values from a group comprising pixels from interpolation nodes, pixels diagonally located adjacent to the interpolation nodes, pixels horizontally adjacent to the interpolation nodes, and pixels vertically adjacent to the interpolation nodes.
