  • Patent number: 9588605
    Abstract: A tracking method of an optical input device includes: capturing a first image as a reference frame and an input image subsequent to the first image as a compare frame while the optical input device operates; computing correlation between the compare frame and the reference frame for a first correlation window to obtain a first peak correlation value; computing another correlation between the compare frame and the reference frame for a second correlation window when the first peak correlation value identified is located at a corner of the first correlation window; when a second peak correlation value of the second correlation window is determined to be greater than the first peak correlation value, computes a displacement information of the optical input device based on the pixel position associated with the second peak correlation value identified in the compare frame.

  • Patent number: 9582061
    Abstract: Embodiments disclosed herein pertain to power conservation for electronic devices. According to one embodiment, power conservation can be achieved through adaptive frame rate control for a display associated with an electronic device. The frame rate is able to be controlled so as to adapt to a frame rate that is adequate for the display task. Since the display often times displays content that is not very dynamic, the frame rate in such situations can be controlled to use a reduced frame rate, which thereby reduces power consumption. However, when the display displays content that is substantially dynamic, the frame rate in such situations can be controlled to use an enhanced (or not reduced) frame rate, which ensures reasonable display quality.

  • Patent number: 9569038
    Abstract: A touch panel of capacitance type includes plural X-electrodes, plural Y-electrodes, and a Z-electrode. Each of the X-electrode and the Y-electrode is formed to have pad portions and thin line portions alternately arranged in an extending direction. The pad portion of the X-electrode and the pad portion of the Y-electrode are arranged without being overlapped in a planar view. The Z-electrode is electrically in a floating state, and formed to be overlapped with both the adjacent X-electrode and the Y-electrode in a planar view. The touched position is calculated based on a local minimal point as an intersection with the interelectrode capacitance value that is equal to or smaller than each of the interelectrode capacitance values of four peripheral intersections among those at the intersections between the plural X-electrodes and the plural Y-electrodes.

  • Patent number: 9547393
    Abstract: A touch-sensitive apparatus comprises a panel configured to conduct signals from a plurality of peripheral incoupling points to a plurality of peripheral outcoupling points. Actual detection lines are defined between pairs of incoupling and outcoupling points to extend across a surface portion of the panel. The signals may be in the form of light, and objects touching the surface portion may affect the light via frustrated total internal reflection (FTIR). A signal generator is coupled to the incoupling points to generate the signals, and a signal detector is coupled to the outcoupling points to generate an output signal. A data processor operates on the output signal to enable identification of touching objects. The output signal is processed (40) to generate a set of data samples, which are indicative of detected energy for at least a subset of the actual detection lines.

    Abstract: A pen-shaped coordinate indicator is provided, which is capable of preventing erroneous detection of the pressing force (writing pressure) and widening the detection range of the pressing force. The indicator includes a core body that forms a pen tip; a columnar first magnetic body having one end in contact with the core body and having another end opposing a columnar second magnetic body; and an elastic body provided between the first and second magnetic bodies. The elastic body is composed of a main body and at least one projection provided thereon, wherein the projection has a smaller resistance to the pressing force applied to the core body than the main body. When the pressing force is applied, initially the projection is mainly deformed, and thereafter the main body is mainly deformed to thereby change a distance between the first and second magnetic bodies according to the pressing force device.
