摘要:
An embodiment of the invention provides an orientation detection method for a portable device. The method comprises acquiring an accelerometer data, determining whether the portable device is in a flat status, determining whether the portable device is in a stable status, and when the portable device is determined in both the flat status and the stable status, stopping acquiring the accelerometer data until receiving an enable signal.

A scaling-up control method and a scaling-up control apparatus are used in a display device. The display device includes a scaler for converting an original image signal into an output image signal by performing a linear interpolation. Moreover, by utilizing a global locking mechanism and a local locking mechanism to perform the linear interpolation to determine the actual position of the interpolated pixel, the position error of the pixel position is largely reduced. Since the difference between the calculated pixel value and the ideal pixel value is reduced, the imaging quality of the output image signal is enhanced.

A method for processing display data includes: storing an image data in a plurality of first-type memories by taking scanning line data as a unit; providing one of the scanning line data stored in a particular memory of the first-type memories to one of a plurality of second-type memories, the particular memory being one of the first-type memories, which are not receiving and storing the image data; and outputting the scanning line data stored in the second-type memories. Time periods for outputting the scanning line data of the image data from the second-type memories are not overlapped.
