Latest Patents

Among his latest patents is a lens position detecting circuit and method. This invention detects the position of a lens by utilizing a phototransistor to sense light emitted from a photodiode, which varies according to the lens position. A control unit divides the lens's moving range into multiple areas, approximating the relationship between lens positions and the current of the phototransistor for each area. The control unit then corrects the current of the phototransistor using this approximated relationship to obtain a corrected detection current that has a linear relationship with respect to lens positions. Ultimately, the position of the lens is detected using the corrected detection current.
