| 20090167902 | IMAGE NOISE REDUCTION METHOD BASED ON OPTIMAL PRIMARY-COLOR SIGNAL - An image noise reduction method based on an optimal primary-color signal is suitable for a digital camera to reduce noises in a digital image. The image noise reduction method mainly includes the following steps, taking out primary-color signals of a digital image, including taking out high-frequency and low-frequency signals of the optimal primary-color signal and high-frequency and low-frequency signals of the worst primary-color signal by using a high-pass filter and a low-pass filter; next, mixing the high-frequency signal of the optimal primary-color signal with that of the worst primary-color signal, and superposing the mixed signal to the low-frequency signal of the worst primary-color signal, so as to get a digital image signal after noise reduction. | 07-02-2009 |

| 20100128370 | LENS MODULE - A lens module includes an upper coupling element, a spring, a magnet yoke, a plurality of magnets, a coil, a lens holder and a lower coupling element. The magnet yoke is disposed under the spring and has a cylindrical inner wall, multiple extension slices and a top wall. The top wall is outwardly extended from an upper edge of the cylindrical inner wall. The extension slices are downwardly and axially extended from a periphery of the top wall and circumferentially arranged on the top wall at regular intervals. The magnets are attached on inner surfaces of respective extension slices of the magnet yoke. At least two raised structures are circumferentially arranged on the lower periphery of the lens holder. The lower coupling element includes at least two concave structures mating with the raised structures. | 05-27-2010 |
| 20100142937 | METHOD AND DEVICE FOR CONTROLLING AUTO MICRO FUNCTION OF LENS MODULE - A method for controlling an auto macro function of a lens module is provided. Firstly, a control switching module is provided. The both terminals of the coil of the lens module are connected to a power source and the control switching module, respectively. In response to a first signal state of a control signal, a constant current is transmitted from the power source to the coil. The magnets attached on the magnet yoke provide a permanent magnetic field, and the constant current passing through the coil causes a magnetic force to be generated on the coil while moving the lens holder toward the magnet yoke by a constant distance. In response to a second signal state of the control signal, the power source stops transmitting the constant current to the coil, wherein a restoring force generated by the deformed spring causes the lens holder to return to its original position. | 06-10-2010 |
