Abstract: A network connection module and a method for selecting a bridging point thereof are disclosed. The method for selecting the bridging point is used for an electronic device to select the bridging point in a network environment which has at least one node capable of connecting to the electronic device. The method includes the following steps: when the electronic device needs to connect, searching for at least one node; confirming whether the electronic device has a connection requirement or whether there is a specified node among the at least one node; if yes, identifying a suitable node from the at least one node based on the connection requirement or the specified node; and if a suitable node is found, randomly selecting a bridging point from the suitable node; and if not, randomly selecting a bridging point from the at least one node.

Abstract: A method of capturing images includes pre-storing a plurality of image templates in a storage device, wherein each of the plurality of image templates includes a predetermined subject. An area of the predetermined subject in each of the plurality of image templates is predetermined. One of the image templates is invoked from the storage device. The predetermined subject of the invoked image template is hollowed according to the area of the predetermined subject, and a hollowed area of the invoked image template is obtained. A captured image is obtained. Once a size of the captured image is adjusted to be equal to a size of the hollowed area of the invoked image template, the hollowed area of the invoked image template is filled with the captured image.

Abstract: A method for detecting whether vertical deviation of an optical disc occurs is provided. First, before a pickup head is successfully focused on the optical disc, a pickup head is actuated based on an input control signal so as to generate a focus error signal with a plurality of S-curves. Then, a plurality of zero crossing points of the S-curves in the focus error signal is identified and a plurality of input control values respectively corresponding to the zero crossing points is obtained. A variation of the input control values is then calculated. Whether vertical deviation of the optical disc occurs can be determined according to the variation of the input control values.

Abstract: A method is provided to detect whether vertical deviation occurs as an optical disc spins in an optical disc player having a pickup head pre-installed in a balanced position at a focal distance. When moving towards and away from the balanced position, the pickup head generates a focus error signal with an S-curve. According to an input control signal, a focus actuator actuates the pickup head to keep it substantially at the focal distance. When the pickup head is not focused, the waveform of the input control signal is designed to actuate the pickup head back and forth within a predetermined range to generate the focus error signal with S-curves. Zero crossing points of S-curves are identified and input control values in the input control signal are obtained accordingly. The variation of the input control values is calculated, and whether vertical deviation occurs is determined by a predetermined procedure.

Abstract: Read focus error (FE) bias is calibrated on an embossed area of the optical disc. OPC is then performed with the calibrated servo signal bias to obtain a write power level. Data are written on and read from the optical disc based on the write power level and the calibrated servo signal bias.
