摘要:
A method of processing a mosaic digital image includes simultaneously performing edge-sensitive denoising and color interpolation on a first color plane of the digital image. The interpolation fills in missing pixel information in the first color plane.

摘要:
Various embodiments for transferring and/or decompressing data blocks are described. In an embodiment, a memory transfer engine transfers a first data block from a nonvolatile memory to a volatile memory. A processor may decompress the transferred first data block. Furthermore, the memory transfer engine may initiate a transfer of a second data block from the nonvolatile memory to the volatile memory prior to the processor completing the decompression of the transferred first data block.
摘要:
A method and apparatus for improving the quality of MPEG video are disclosed. In a preferred embodiment, a group of pictures (GOP) is obtained and decompressed, producing an initial decompressed GOP. This initial decompressed GOP is spatially shifted to at least two shift positions. At each shift position, MPEG compression and decompression are applied, producing a resulting decompressed GOP for each shift position. The resulting decompressed GOPs are shifted back to their initial position and combined, preferably by averaging, to form an improved GOP.

A camera has a motion detector and a sensor with a plurality of pixels. Each pixel includes shift transistors to shift charge between pixels as a function of motion sensed by the motion detector.
摘要:
A digital imaging device having a CCD sensor array with at least one field captures both short and long exposures of a particular field during the capture of a single image frame, the short-exposure image data from the particular field being used to extend the dynamic range of clipped pixel data.

A system and method for stabilization of an image capture device are disclosed. Also disclosed are a system and method for autofocus of an image capture device.
摘要:
The shutter of a digital imaging device may be calibrated by comparing a characteristic of two separate exposures obtained from a single field of the device's imaging sensor during a single exposure cycle. Calibrating the shutter in this manner facilitates the accuracy of even very short exposure times.
摘要:
In a method of digital image compression, the spatial frequency content of a digital image is characterized using a relatively sparse sampling of data blocks from the image, and a quantization table is constructed based on the characterization of the spatial frequency content.
