20140375228 | LIGHTING CONTROL METHOD BY MULTI-TONE MULTI-FREQUENCY SIGNAL AND DEVICE USING THE SAME - The present invention provides a lighting control method by multi-tone multi-frequency signal, which includes: encoding a control signal into a multi-tone multi-frequency signal in a control unit; transmitting the multi-tone multi-frequency signal to a receiving unit; decoding the multi-tone multi-frequency signal to generate a command; and controlling a lighting status of at least one lighting device according to the command. The present invention also provides a device using the aforementioned lighting control method. | 12-25-2014 |
20140306892 | METHOD OF DYNAMICALLY ADJUSTING IMAGE FRAME RATE AND DEVICE USING SAME - The invention provides a method for dynamically adjusting image frame rate, which includes: sequentially obtaining plural displacements; accumulating a count of the displacement is sequentially higher than a first threshold value, to increase an image frame rate if the count is larger than a first reference value; and accumulating a count of the displacement is sequentially lower than a second threshold value, to reduce the image frame rate if the accumulated count is larger than a second reference value. | 10-16-2014 |
20140185866 | OPTICAL NAVIGATION METHOD AND DEVICE USING SAME - The invention provides an optical navigation method, which includes: sequentially obtaining plural images including a first image, a second image, and a third image; choosing a main reference block in the first image; comparing the main reference block and the second image by block matching comparison to determine a first motion vector; resizing the main reference block according to the first motion vector to generate an ancillary reference block having a size smaller than the main reference block; and comparing the ancillary reference block and the third image by block matching comparison to determine a second motion vector. | 07-03-2014 |
20140132787 | Motion Detection Device and Motion Detection Method Having Rotation Calibration Function - The present invention provides a motion detection device and a motion detection method having a rotation calibrating function. The motion detection device detects a relative motion of a DUD (device under detection) with respect to a reference light source. The motion detection device includes a rotation sensor, an image sensor, and a coordinate transfer unit. The rotation sensor is disposed on the DUD for detecting rotation of the DUD to generate rotation information. The image sensor captures an image generated by the reference light source, to obtain an absolute coordinate according to a coordinate system related to the image sensor. The coordinate transfer unit calibrates the absolute coordinate according to the rotation information to generate a calibrated coordinate. | 05-15-2014 |
