摘要： An optical navigation system with a lift detection module is provided for preventing cursor movement if the optical navigation system has been lifted from the navigation surface. The optical navigation system may include an image sensor, a controller and a lift detection module. The lift detection module may be operatively coupled with the image sensor and the controller to selectively report a motion data upon determining a lift by comparing the average of the photosensitive pixel elements with a pixel element threshold value and the surface quality value with a surface quality threshold value. The lift detection module may be incorporated in a microcontroller, wherein the microcontroller may be added to a navigation system to provide an additional lift detection feature.

摘要： An imaging apparatus is described for obtaining images. The imaging apparatus includes a pixel array, a row decoder, a column decoder, and a trigger circuit. The pixel array integrates electrical signals corresponding to incident light from a scene. The row decoder enables a selected row of pixels within the pixel array. The column decoder enables readout of a pixel in a selected column of the selected row within the pixel array. The trigger circuit generates one or more burst pulses to traverse through a corresponding number of decoder stages that correspond to pixels which are identified for discarding. Each burst pulse has a duration that is less than a stipulated minimum pulse duration of a typical decoder pulse of the decoders. By using shorter burst pulses, the trigger circuit can quickly jump to a desired row and/or column of pixels for readout, while conserving power.

摘要： An optical finger navigation system with object detection is provided for preventing cursor movement if a user's finger has been lifted from the navigation surface. The optical finger navigation system may include a light source, an image sensor and an object detection engine. The object detection engine may be operatively coupled with the image sensor and the light source to selectively report motion data upon determining the presence of an object by comparing a scaled-up pixel value with a threshold value. The lift detection engine may be incorporated in a microcontroller, wherein the microcontroller may be added to a navigation system to provide an additional object detection feature.
