  • Patent number: 10853909
    Abstract: The present invention relates to an image processing apparatus which determines an order for calculating output image pixels that maximally reuses data in a local memory for computing all relevant output image pixels. Thus, the same set of data is re-used until it is no longer necessary. Output image pixel locations are browsed to determine pixel values in an order imposed by available input data, rather than in an order imposed by pixel positions in the output image. Consequently, the amount of storage required for local memory as well as the number of input image read requests and data read from memory containing the input image is minimized.

  • Patent number: 10853913
    Abstract: Methods, systems, and devices for processing color information are described. The method may include receiving a first set of image data collected at an image sensor based on a first color filter array having a first filter pattern, calculating a color saturation gradient based on the first set of image data, and calculating multiple color gradients based on the color saturation gradient. The multiple color gradients may each be associated with a region of the first set of image data, where each color gradient characterizes a color variation along a different direction of the region. The method may include generating a second set of image data including a color value for the region based on comparing a first direction gradient of the multiple color gradients with a second direction gradient of the multiple color gradients. Color values associated with the regions may be mapped to a second color filter array.

  • Patent number: 10783608
    Abstract: The invention relates to the processing operation of interpolating the colours of a Bayer mosaic image sensor. A first elementary matrix filter, which is a bilinear interpolation filter, of size m×m, m being an odd number larger than or equal to 3, a low-pass matrix filter of size n×n, n being an odd number larger than or equal to 3, and a high-pass matrix filter, complementary to the low-pass filter, of size n×n, are defined. The first matrix filter is convoluted with the low-pass filter, resulting in a low-frequency interpolation filter of size (m+n?1)×(m+n?1), and the first matrix filter is convoluted with the high-pass filter, resulting in a high-frequency interpolation filter of size (m+n?1)×(m+n?1). The matrix of digital signals arising from the pixels is filtered separately, using the pixels of each colour, by the low-frequency interpolation filter. The complete matrix of signals is filtered using the high-frequency interpolation filter.
