  • Patent number: 12244937
    Abstract: Disclosed herein are improvements to pixel pattern conversion, upsampling, and IR decontamination processes. An example includes an image processing pipeline comprising an upstream component, a pattern conversion component downstream with respect to the upstream component in the image processing pipeline, and a downstream component relative to the pattern conversion component. The pattern conversion component is configured to obtain RGB-IR pixel data produced by the upstream component of the image processing pipeline and convert the RGB-IR pixel data into RGB pixel data and IR pixel data using a conversion engine. The conversion engine is configured to demosaic the RGB-IR pixel into the RGB pixel data and the IR pixel data, remosaic the RGB pixel data into an RGB pattern and the IR pixel data into an IR pattern and remove IR contamination from the RGB pixel data of the RGB pattern for use by the downstream component.

  • Patent number: 10506243
    Abstract: A video encoder and decoder are described. The encoder operates on luma data and chroma data. The luma data is split into two channels. The channel split can be based on frequency regions or based on even and odd lines. When the channel split is based on frequency regions, the encoder produces a channel with low frequency data and a channel with high frequency data. A third channel holds chroma data. The decoder recovers the split luma data and the third channel of chroma data. The decoder may then generate one or more pixels to be stored in a line buffer.

  • Patent number: 9947083
    Abstract: The image processing method includes acquiring an input image produced by image capturing using an optical system, acquiring a first noise amount contained in the input image, performing a resolution enhancement process on the input image, performing frequency decomposition of the input image into multiple decomposed images that are mutually different frequency band components, and calculating, on a basis of the first noise amount and a frequency characteristic of the resolution enhancement process, a second noise amount contained in each of areas of each of the multiple decomposed images. The method further includes performing a noise reduction process on each area of each decomposed image on a basis of the second noise amount calculated for that area, and combining the multiple decomposed images each subjected to the noise reduction process together.

  • Patent number: 9507115
    Abstract: Disclosed is a method for determining edges of an overlapping region between a color filter and a black matrix, which comprises the following steps. An original gray-scale value curve and a differential gray-scale value curve of the measurement area to be detected are drawn, and extremums of the differential gray-scale value curve are determined. A gray-scale value of the overlapping region between the color filter and the black matrix is obtained. A threshold value is established. Two extremums of the differential gray-scale value curve which are the closest to the two intersections respectively are obtained, and then the edges of the overlapping region between the color filter and the black matrix are determined based on the two extremums.
