摘要： An optical navigation system with optical imaging of multiple inputs using a single navigation sensor. The optical navigation system includes a tactile interface device, an image sensor, and a processor. The tactile interface device facilitates a navigation input. The image sensor intermittently generates images of a surface of the tactile interface device and images of a contact navigation surface. The image sensor also generates the images of the surface of the tactile interface device exclusive of the images of the contact navigation surface. The processor is coupled to the image sensor. The processor generates a first navigation signal based on the images of the tactile interface device and generates a second navigation signal based on the images of the contact navigation surface.

摘要： A control circuit having a drive circuit and a controller adapted for use in optical mice is disclosed. The drive circuit is connected between first and second ports and passes a current between those ports having an amplitude determined by a control signal that is generated by the controller. The first port is connected to an illumination device and the second port is connected to a power rail. The control circuit also includes a potential measuring circuit that generates a signal indicative of a drive circuit potential between the first and second ports. The controller records the drive circuit potential for a predetermined current when the first port is connected to an illumination device. The controller sets the control signal based on the recorded drive circuit potential. The control circuit can record the drive circuit potential when the controller is powered.

摘要： An optical navigation device, such an optical mouse, includes a housing, an illumination system, a tracking engine, and multiple height-specific imaging systems located within the housing. The height-specific imaging systems generate image information in response to reflected light from a navigation surface and each one the height-specific imaging systems is positioned to detect the largest portion of reflected light at a different separation distance between the housing and the navigation surface. An integrated circuit (IC) device for optical navigation includes an aperture plate having height-specific apertures and height-specific navigation sensor arrays aligned in one-to-one correspondence with the height-specific apertures and configured to generate image information in response to light that passes through the corresponding height-specific apertures. An optical element for use in an optical navigation system includes an illumination source lens and multiple height-specific focal lenses.

摘要： An optical navigation system having two or more optical pipelines for image acquisition and a single multiplexed optical array. Each of the two or more optical pipelines for image acquisition may include an illuminator that emits optical radiation at a navigation surface where each navigation surface is separate from the other navigation surfaces. The single multiplexed optical array may be configured to receive optical radiation reflected from the respective navigation surfaces. The optical navigation system may further include illuminator drivers that control each of the optical pipelines for image acquisition and an optical sensor that is configured to multiplex the images recovered by the optical pipelines for image acquisition and perform image correlation for the different navigation surfaces.
