摘要： Methods and systems for data compression and decompression are disclosed. Specifically, the method for data compression of the present invention receives eight inputs representing pixel information of an image and performs a combination of an 8-point discrete cosine transform (DCT) and weighting function to obtain eight outputs representing digital representations of an image. The method for data decompression receives eight inputs representing digital representations of an image and performs a combination of an inverse weighting function and an 8-point inverse discrete cosine transform (IDCT) to obtain pixel components of an image.

摘要： A method and apparatus for selecting a quantization table containing quantization coefficients for encoding image data. A set of quantization tables is examined to determine a quantization table which meets a predetermined selection criteria. If such a quantization table is not the first table examined, other tables in the vicinity of a neighborhood of tables are examined utilizing linear searching techniques. If a quantization table which meets the selection criteria is not determined in the vicinity of the neighborhood of tables, quantization tables outside the vicinity of the neighborhood of tables are examined utilizing binary searching techniques.

摘要： A hybrid imaging device is configured to capture low resolution video and high resolution still images. The imaging device is configured to apply motion information obtained from the low resolution video to a reference high resolution still image to generate a missing moment of interest high resolution still image. The low-resolution video is captured at a high frame rate in conjunction with a few high-resolution still pictures taken at periodic intervals. A user locates a desired scene of interest, e.g. a moment of interest, from the captured video, and a post-processing technique is used to generate the high resolution still picture corresponding to the selected moment of interest. The high resolution still image is generated using texture information from one or more nearby captured high resolution still images and motion information from the low-resolution video frame corresponding to the selected moment of interest.

摘要： An apparatus and method for post processing image data which previously was encoded using a discrete cosine transform in order to remove resulting blocking effects. Possible blocking points are examined to determine whether blocking points exist. If blocking points are determined, an adjustment value for each blocking point is computed and proportionately utilized to adjust the adjacent and neighboring pixels.

摘要： An apparatus and method for post processing image data which previously was encoded using a discrete cosine transform in order to remove resulting blocking effects. Correction coefficients are generated by determining the least mean square error of the blocking error. The correction coefficients are adjusted to be within the quantization range of the quantization step size used during the coding process. The adjusted correction coefficients are then used to generate the correction terms which are subsequently combined with the original image data to generate an image exhibiting reduced blocking effects when the image is displayed.
