摘要： Optical motion sensing systems and methods are described. In one aspect, light from subfields of a scene is focused onto respective capture areas of a focal plane. Successive sets of contemporaneous local images are captured from the focused light. Respective saliency measures are derived from respective ones of the local images. Respective local motion measures are determined from comparisons of corresponding ones of the local images in ones of the contemporaneous local image sets. A respective global motion measure is produced for each of the contemporaneous local image sets based on the respective ones of the local motion measures and the respective ones of the saliency measures.

摘要： In one embodiment of the invention, a method for providing three-dimensional motion inputs to a device includes measuring characteristics (e.g., capacitances) between sense electrodes and a reference electrode on a movable pad, determining three-dimensional displacements of the movable pad from the capacitances, determining the three-dimensional motion inputs from the three-dimensional displacements of the movable pad, and providing the three-dimensional motion inputs to the device. In another embodiment of the invention, a pointing device mounted on a surface of a host device includes sense electrodes, a frame, a movable pad flexibly mounted in an opening of the frame. The movable pad includes a reference electrode opposite the sense electrodes. The opening limits the motion of the movable pad to a single axis on the surface and to an axis into the surface.

摘要： Systems, methods, and computer readable media to register images in real-time and that are capable of producing reliable registrations even when the number of high frequency image features is small. The disclosed techniques may also provide a quantitative measure of a registration's quality. The latter may be used to inform the user and/or to automatically determine when visual registration techniques may be less accurate than motion sensor-based approaches. When such a case is detected, an image capture device may be automatically switched from visual-based to sensor-based registration. Disclosed techniques quickly determine indicators of an image's overall composition (row and column projections) which may be used to determine the translation of a first image, relative to a second image. The translation so determined may be used to align/register the two images.

摘要： A pointing device has a pointing device surface and a sliding structure that moves with respect to the pointing device surface. A detector outputs a value that varies as the sliding structure moves with respect to the pointing device surface. A controller estimates the sliding structure location on the pointing device surface by calculating an approximate distance. The approximate distance is calculated by multiplying a measured differential of the value times a conversion constant. The controller adjusts the approximate distance to take into account non-linearity of the measured differential.

摘要： An image device, such as a digital camera, detects specific repeating patterns of signal variations by processing columnar information from the device's two-dimensional sensor array used to generate images. In one embodiment, the columnar information is derived from calculating row averages for two image frames, with each row average being a computed average of the multiple signal intensities generated from some or all of the sensors within a particular row. After the columnar information is determined for each of the two frames, a difference signal is generated as a sequence of the differences between the row averages for the first frame and the row averages for the second frame. This row averaging and frame differencing removes a large percentage of the signal energy that is not a result of the artifact of interest, such as the flicker generated by illumination having intensity fluctuations at 100 Hz or at 120 Hz. In some embodiments of the invention, the row averaging and/or the frame-to-frame comparison are deleted.
