Abstract: PROBLEM TO BE SOLVED: To remove grain by spatially filtering images. SOLUTION: A method for removing the grain by spatially filtering the images in an optical navigation system is provided. While performing navigation using a first filter, an ordered collection of correlation values is generated. Whether or not a ridge is present in a correlation surface described by the values of the ordered collection is tested. When the ridge is present, the navigation is started using a second filter. During the navigation, the ordered collection of the correlation values produced while the second filter is in use is tested. The navigation is continued while the examination reveals the absence of the ridge and the navigation with the first filter is restarted when it reveals the presence of the ridge. For the second filter, the filter most effectively dealing with the revealed ridge is selected from third and fourth filters spatially oriented at 90 deg. to one another.

Abstract: PROBLEM TO BE SOLVED: To provide an optical pointing device capable of providing the inertial effects of a track boll by using an optical pointing device. SOLUTION: An apparatus (1) for controlling the position of a screen pointer of an electronic device having a display screen is provided with an imaging surface (5) against which a top end part (6) of a human digit (7) may be placed, a light source (2) for illuminating the tip of the digit placed on the imaging surface, and for forming a reflected image, a motion transducer (9), a lens (8) for receiving the reflected image, and for directing this to the motion transducer, and a controller (40). The motion transducer generates the digital expression data of the reflected image, and generates the first movement data set indicating the movement of the tip of the digit across the imaging surface based on the digital expression data. When the tip of the human digit is removed from the imaging surface, the controller generates the second movement data set indicating the movement of the tip of the digit on the imaging surface before the tip of the digit is removed from the imaging surface.

Abstract: An apparatus for controlling the position of a screen pointer for an electronic device having a display screen includes an imaging surface against which a portion of the tip of a human digit may be placed. A light source illuminates that portion of the tip of the digit that is placed against the imaging surface, thereby generating reflected images. The apparatus includes a motion transducer. A lens receives the reflected images and directs the reflected images onto the motion transducer. The motion transducer generates digital representations of the reflected images. The motion transducer generates a first set of movement data based on the digital representations of the reflected images. The first set of movement data is indicative of motion of the tip of the digit across the imaging surface. A controller generates a second set of movement data when the tip of the human digit is removed from the imaging surface. The second set of movement data is indicative of motion of the tip of the digit across the imaging surface prior to removal of the tip.

Abstract: Apparatus (1) for controlling the position of a screen pointer for an electronic device which has a display screen. It includes imaging surface(5) against which a portion of the tip (6) of a finger (7) may be placed. A light source (2) illuminates the portion of the finger placed on the imaging surface, generating reflected images which are focussed on a motion transducer (9). This in turn generates digitized image and subsequently a first set of movement data. A controller produces a second set of movement data when the finger is removed. This second set of data can be indicative of the way that finger has moved (i.e. whether it has flicked fast or slow). The controller can simulate a kind of inertia into the pointer movement which resembles the response usually taken from the pointing devices which have mechanical parts when they are imparted a flicker by user's finger, (i.e a decelerating movement of pointer on the screen). The decelerating response can be adjusted by the user through the controller.

Abstract: Optical navigation upon grainy surfaces whose orientation is inclined at about 45 DEG to the X and Y axes of the navigation mechanism is enhanced by: first detect that a spatial filter in use is inappropriate for the orientation presently occurring, and: second, employ a different and more appropriate spatial filter subsequent to such detection. The shape of a correlation surface (89) used in the navigation process is tested (93,94) for the presence of a ridge in the correlation surface. This generates control metrics whose filtered excursions are tracked by a control system that changes the spatial filter in use. The direction from which illumination arrives relative to the X and Y axes affects the range of angles (relative to, say, the Y axis) that a filter is effective, by changing the apparent size and proportions of the highlights and shadows that are the perceived features ultimately navigated upon. Stable operation of the control system can be enhanced by ensuring overlap of the filters' ranges, and can be promoted by dynamically altering (102) the direction from which illumination reaches the navigation surface(Fig. 14), so that it corresponds to, or varies in relation with, the filter in use.
