摘要： An auto-focus (AF) method adapted for an image capturing device includes following steps. When a first press signal generated by a user pressing a button of the image capturing device is detected, a local peak searching method is applied to perform an AF procedure. It is determined whether a second press signal generated by the user pressing the button is detected. If not, it is determined whether a first released signal generated by the user releasing the button is detected. The continuous pressing count is calculated according to the first released signal and the first press signal that are continuously generated. Whether the continuous pressing count is greater than a first threshold is determined. If yes, a global peak searching method is applied to perform the AF procedure. If not, the local peak searching method is still applied to perform the AF procedure.

摘要： Disclosed is a multistage charging circuit for driving liquid crystal displays, designed particularly to provide a multistage charging driving circuit for liquid crystal display, in which the pixels can be pre-charged to a determined voltage value before the next data are written by performing charge-sharing and pre-charge. Due to the fact that the voltage and the next data have the same polarity, the problems resulted from gray-scale voltage imprecision and latch up at the output can be prevented and thus high gray-scale precision and low power dissipation can be achieved.
