Abstract: High dynamic range media sensor output is encoded using a hybrid transfer function. The hybrid transfer function conforms to existing industry standards over standard brightness level ranges, such as between black and white reference points, and uses a different function to encode captured signals having intensities below the black point and above the white point. Precision over the expanded dynamic range of captured image data is optimally preserved using a two-byte per pixel representation. The transfer function varies across the full dynamic range without clamping off below the maximum value of the expanded captured intensity range. One hybrid transfer function conforms to BT.1886 up to the white point, and uses a linearly varying encoding gamma above the white point up to 1300% IRE, producing encoded values in a 2.14 fixed point representation. The hybrid transfer function is continuous at the white point, and may also have a continuous gradient there.

Abstract: A simple, fast, and effective method is provided for background removal for document images with dark text over relatively uniform or slow-varying non-white background. Candidate regions for background removal are first identified by binarizing the input gray-scale image using a global threshold very close to white. Large contours in the binarized image are identified as candidate regions. A histogram analysis is applied to preliminarily identify regions containing graphics, which are excluded from further processing. The remaining candidate regions are individually binarized. The binarized regions are analyzed to determine whether they contain graphics or text/table, by examining their geometric characteristics and statistics of connected components within them. For candidate regions determined to contain text or tables, background pixels in the input image are set to white using a mask which is the inverse of the individually binarized images of the regions. Regions that contain graphics are left unchanged.

Abstract: An image processing apparatus executes color conversion so that when printing is performed based on image data compressed and decompressed with a lossy compression method, the image data reproduces expected colors of the image data before compression. More specifically, a range of a signal value of a black image affected by compression of image data, such as black character to be printed with black ink, is obtained, and a color separation table is generated such that color ink is not used but black ink is used within this range. This allows the image data to reproduce expected colors of the image data before compression when printing is performed based on the image data compressed and decompressed with a lossy compression method.

Abstract: Compression and decompression of numerical data can apply to floating-point or integer samples. Floating-point samples are converted to integer samples and the integer samples are compressed and encoded to produce compressed data for compressed data packets. For decompression, the compressed data retrieved from compressed data packets are decompressed to produce decompressed integer samples. The decompressed integer samples may be converted to reconstruct floating-point samples. Adaptive architectures can be applied for integer compression and decompression using one or two FIFO buffers and one or two configurable adder/subtractors. Various parameters can adapt the operations of adaptive architectures as appropriate for different data characteristics. The parameters can be encoded for the compressed data packet. This abstract does not limit the scope of the invention as described in the claims.
