摘要： The image data are coded with field DCT or frame DCT depending on the characteristics of the image data. However different coding types will result in different boundary marks of boundaries between adjacent blocks or adjacent macro blocks. Therefore the de-blocking of a boundary between two adjacent blocks or adjacent macro blocks should be performed according to the format of image data and the coding type of the adjacent blocks or adjacent macro blocks.

摘要： An image processing system having scaling and sharpness device and method thereof are described. The global frequency detecting unit calculates a vertical frequency level of the input pixels along a vertical direction and a horizontal frequency level along a horizontal direction. The gradient-calculating summation unit calculates a set of gradient brightness levels according to a portion of the input pixels along a set of directions respectively. The threshold-adjusting device adjusts a first threshold and a second threshold based on the relationship of the vertical frequency level and the horizontal frequency level. The image blending device determines a cross-angle direction with the first threshold from the threshold-adjusting device and determines a minimum-angle direction with the second threshold from the threshold-adjusting device, wherein the image blending device generates the first pattern associated with the cross-angle direction and the second pattern associated with the minimum-angle direction and blends the first pattern with the second pattern based on the weighting factor value.

摘要： The present invention provides a way of hysteretic switching for efficiently reducing the heavy switching between two adjacent coarse intervals. The present invention disposes a number of fine intervals to cover a range which is larger than the length of one coarse interval. Each coarse interval comprises some extra fine intervals which are exceeded the boundary of the coarse intervals in one side. The heavy switching will be postponed until the extra fine intervals are used up. In the meantime, the fine calibration unit records the number of extra fine interval which be used. An extra-boundary value will be recorded in the fine calibration unit for determining an initial fine interval in another coarse interval if the heavy switching occurs. It should be noted that the extra-boundary value could be a positive or minus value corresponding to which a forward coarse interval or a backward coarse interval the reference signal drifts into. The present invention also provides a method for reducing heavy switching between two coarse intervals. It is obvious that the probability of the heavy switching occurring will be efficiently decreased by the way of hysteretic switching of the present invention. Furthermore, the mismatch and noises due to the heavy switching between the coarse intervals can be effectively diminished.

摘要： A method and apparatus for detecting the transmitted mode and guard interval length. The mode detection is adopted by the DVB-T system to increase system flexibility and combat multi-path interference in the transmission environment, of the received OFDM signals by applying the concepts of down-sampling and correlation. The unique combination of down-sampling and correlation method requires far less memory than the traditional correlation methods. By comparing the indicators resulting from output of each correlation module, the transmitted mode and guard interval length are detected with much greater reliability.

摘要： An ESD protection circuit is disclosed. The ESD protection circuit includes a stacked MOS circuit and a trigger current generating circuit. The trigger current generating circuit will generate trigger signal(s) to turn on the stacked MOS circuit under ESD stress condition. The ESD voltage can thus be discharged through the current path formed by the stacked MOS circuit. A lower trigger voltage is achieved by technologies disclosed, which will make an integrated circuit more sensitive to ESD.
