摘要： Image processing using various video and still flows is described. The resolution and bit depth at each stage of the image processing are described. In some examples, image scalers are used to resize image resolution. In some examples, a warp engine is used to distort per frame images to apply image stabilization, zoom, or a user digital lens. An image processing pipeline includes a double data rate (DDR) memory buffer that supports lossy compression with a constant 50% compression. In some examples, the image processing pipeline includes a DDR memory buffer that is uncompressed.

摘要： An image processing circuit for multi-illumination white balance with thumbnail processing. The image processing circuit determines a set of initial weights for a source pixel in a thumbnail image by determining component values for multiple color channels of the source pixel. The image processing circuit determines a set of weights for the source pixel in a weight map for the thumbnail image. Each weight in the set of weights is determined based on corresponding initial weights from the set of initial weights. Each weight in the set of weights represents an intensity level of a respective chrominance class of multiple chrominance classes for the source pixel. The image processing circuit applies the set of weights to values of the color channels of the source pixel to generate color component values of the color channels of a target pixel in a target thumbnail image.

摘要： A method for converting an initial datum between a colour space of a first colorimetric system and a colour space of a second colorimetric system, the initial datum being formed of at least one element expressed in a colorimetric reference system, the method includes: converting the initial datum into a projected datum, by expressing the at least one element in the colour space of the first colorimetric system; adapting the projected datum into an adapted datum, by expressing the at least one element in the colour space of the second colorimetric system. The colour space of the first colorimetric system and of the second colorimetric system are each a hyperbolic space defined by a hyperbolic metric projective reference system.

摘要： In various examples, image processing techniques are presented for reducing artifacts in images for autonomous or semi-autonomous systems and applications. Systems and methods are disclosed for deferring at least a portion of a strength associated with a color correction matrix (CCM) of an image processing pipeline to one or more other stages associated with the image processing pipeline. For instance, the CCM is used to determine a first CCM and a second, deferred CCM. The first CCM may be associated with an earlier stage of the image processing pipeline while the deferred CCM is associated with a later stage of the image processing pipeline. In some examples, the deferred CCM is combined with another matrix, such as a color space conversion matrix. By deferring part of the CCM, the image processing pipeline may reduce a number of artifacts and/or eliminate the artifacts that occur when processing image data.
