Abstract: The present disclosure relates to a method of counting step-number. When detecting step-number executed by an electronic device, a g-sensor of the electronic device detects whether the moving speed is normal (one step per second), i.e. the detection result is the G value, or the movement speed has abnormal variation (such as one step per two seconds or five seconds), i.e. the detection result is the G value at Y axis, and the electronic device computes the step-number according to sums of maximum values and minimum values of speed variations every second within a counting period, and average of the sums. The processing unit determines the variation of the step-numbers of the G values and the G values at Y axis, and selects one of the two step-numbers for use as a correct step-number detection result, so as to achieve the objective of precisely computing step-number upon the speed variation.

Abstract: A portable apparatus including a touch display panel, a communication interface and a processing unit is provided. The processing unit generates first reference coordinates according to at least one touch point on the touch display panel, operates according to the first reference coordinates indicating a reference position in a frame displayed by the touch display panel, and generates first frame data to the touch display panel. When the communication interface is coupled to an external display apparatus, the processing unit generates second reference coordinates according to at least one touch point on the touch display panel, operates according to the second reference coordinates indicating a reference position in a frame displayed by the external display apparatus, and generates and transmits second frame data to the external display apparatus via the communication interface.

Abstract: The invention discloses a method for transmitting image bit stream and an image encoder utilizing the method. The image format comprises a start of image (SOI) marker, a start of scan (SOS) marker and a primary compressed data. First, the invention generates redundant data according to a first start address of the SOI marker, a data size between the SOI marker and the SOS marker, and a second start address of the primary compressed data. Afterward, the redundant data is selectively padded into the image bit stream between the SOI marker and the SOS marker. Accordingly, the required time for transmitting image data to a storage medium will be reduced, and the transmission performance will be improved apparently by utilizing the method.
