  • Patent number: 11314845
    Abstract: Interpolation logic described herein provides a good approximation to a bicubic interpolation, which is generally smoother than bilinear interpolation, without performing all the calculations normally needed for a bicubic interpolation. This allows an approximation of smooth bicubic interpolation to be performed on devices (e.g. mobile devices) which have limited processing resources. At each of a set of predetermined interpolation positions within an array of data points, a set of predetermined weights represent a bicubic interpolation which can be applied to the data points. For a plurality of the predetermined interpolation positions which surround the sampling position, the corresponding sets of predetermined weights and the data points are used to determine a plurality of surrounding interpolated values which represent results of performing the bicubic interpolation at the surrounding predetermined interpolation positions.

  • Patent number: 9583060
    Abstract: A low-resolution image is displayed at higher resolution and afterimages are reduced. Resolution is made higher by super-resolution processing. In this case, the super-resolution processing is performed after frame interpolation processing is performed. Further, in that case, the super-resolution processing is performed using a plurality of processing systems. Therefore, even when frame frequency is made higher, the super-resolution processing can be performed at high speed. Further, since frame rate doubling is performed by the frame interpolation processing, afterimages can be reduced.

    Abstract: At least one image processing apparatus is provided which allows performing a demosaicing process on a polychrome image signal with high accuracy. The at least one image processing apparatus performs an interpolation process in each of a plurality of defined directions on a mosaic image signal and acquires an evaluation value representing a correlation in each of a horizontal direction and a vertical direction for each of a plurality of pixels of the image signal having undergone the interpolation process. The evaluation values for at least one pixel of interest are corrected based on the evaluation values for peripheral pixels if a predetermined condition including a condition that it is determined that the at least one pixel of interest is an isolated point is satisfied. Then, the image signal after the at least one pixel of interest is interpolated based on the corrected evaluation values.

  • Patent number: 9336558
    Abstract: In the video encoders described herein, blocks of pixels from a video frame may be encoded (e.g., using CAVLC encoding) in a block processing pipeline using wavefront ordering (e.g., in knight's order). Each of the encoded blocks may be written to a particular one of multiple DMA buffers such that the encoded blocks written to each of the buffers represent consecutive blocks of the video frame in scan order. A transcode pipeline may operate in parallel with (or at least overlapping) the operation of the block processing pipeline. The transcode pipeline may read encoded blocks from the buffers in scan order and merge them into a single bit stream (in scan order). A transcoder core of the transcode pipeline may decode the encoded blocks and encode them using a different encoding process (e.g., CABAC). In some cases, the transcoder may be bypassed.
