摘要： A computer readable media having at least one program code recorded thereon. An interference image determining method can be performed when the program code is read and executed. The interference image determining method comprises: (a) controlling a light source to illuminate an object on a detecting surface to generate an image; (b) controlling a sensor to catch a current frame of the image; (c) utilizing an image characteristic included in the current frame to determine a interference image part of the current frame; and (d) updating a defined interference image according to the determined interference image part.

摘要： The present invention discloses a hybrid pointing device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid pointing device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.

摘要： The present invention provides a click detection method for an optical system including the steps of: acquiring an image frame and calculating a quality parameter thereof; in an initial state, maintaining the initial state when the quality parameter is smaller than or equal to a first threshold while transferring to a first touch state and counting a count value when the quality parameter is larger than the first threshold; and in the first touch state, maintaining the first touch state when the quality parameter is larger than or equal to a second threshold while identifying the count value when the quality parameter is smaller than the second threshold and identifying a single click and transferring to the initial state if the count value is within a first predetermined range. The present invention further provides an optical system.

摘要： A method of increasing signal-to-noise ratio of a distance-measuring device includes a light-emitting component emitting a detecting light to a measured object during an emitting period for generating a reflected light, a delay period after the light-emitting component emitting the detecting light, a light-sensing component sensing the energy of the reflected light to generate a light-sensing signal, and obtaining a measured distance between the distance-measuring device and the measured object according to the energy of the detecting light and the light-sensing signal. Since the measured distance is longer than a predetermined shortest measured distance, the method can accordingly calculate a proper delay period for ensuring that the reflected light reaches the light-sensing component after the delay period. In this way, the light-sensing component does not sense the background light during the delay period, so that the signal-to-noise ratio of the light-sensing signal is improved.

摘要： The present invention discloses a hybrid human-interface device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse or TV controller. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid human-interface device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.
