摘要： A method for imaging includes receiving an input image that includes a matrix of pixels (32) having input pixel values. The input pixel values are processed so as to detect a region of saturation in the input image. A first image filtering operation is applied to the input pixel values of at least the pixels that are outside the region of saturation, so as to generate first filtered pixel values. A second image filtering operation is applied to the input pixel values of at least the pixels that are within the region of saturation, so as to generate second filtered pixel value. An enhanced output image is generated by stitching together the first and second filtered pixel values.

摘要： An image enhancement circuit (26, 60, 190, 260) includes an input interface (64, 262), which is operative to accept a stream of input pixel values belonging to pixels (32) of an input image. The input image includes a plurality of different input sub-images including respective subsets of the pixels, such that the input pixel values of the pixels in the different input sub-images are interleaved in the stream. A plurality of filter cells (92, 144, 206, 222, 238, 364) are connected in a two-dimensional array configuration and are arranged to separately filter the input pixel values of each of the input sub-images with respective two-dimensional deconvolution kernels so as produce respective output sub-images that include output pixel values. A multiplexer (88, 332) is coupled to multiplex together the output pixel values of the output sub-images so as to produce a filtered output image.

摘要： A method and apparatus for processing an image includes a buffer memory, which is configured to receive and store an input data stream including multiple image lines and one or more embedded data lines, which are interleaved with the image lines and include metadata that are not a part of the image. An image processor receives the input pixel values in succession from the buffer memory and processes the input pixel values so as to generate an output data stream including output pixel values, which are different from the input pixel values. A processing controller detects the one or more embedded data lines and controls the image processor, responsively to detecting the one or more embedded data lines, so that the embedded data lines pass through the image processor without modification of the metadata and are interleaved with the image lines of the output pixel values in the output data stream.

摘要： Embodiments of the current invention provide for systems and methods for correcting shading effects in image sensors. More specifically, but not by way of limitation, embodiments of the current invention provide methods and systems for dynamically correcting shading effects for digitally converted outputs from individual pixels on a pixel array in the image sensor, wherein the shading correction may be calculated according to a function of an elliptical-type equation from the radial location of the pixel on the pixel array. In embodiments of the present invention, the correction is performed at the Bayer domain before demosaicing processing to provide for accuracy of shading correction and low power consumption.

摘要： A method of compressing an image according to an image compression algorithm includes sequentially receiving pixel values into a buffers bank in line-by-line order. The image includes a plurality of pixels arranged into lines and columns. Each pixel has a pixel value associated therewith. Each line has L pixels. The image compression algorithm operates on blocks of pixels, each block having N lines and M columns. The method also includes storing each block-line of pixel values in a buffer of the buffers bank. A block-line includes M consecutive pixels of a line. The method also includes, for each block-line, storing a pointer to the buffer in which the block-line is stored and reading block-lines out of the buffers bank to a compression engine, wherein the block-lines are read out of the buffers bank in an order that is different from the line-by-line order in which the block-lines were received into the buffers bank. The method further includes compressing the image according to the image compression algorithm and displaying the image.
