Azona Optical Mouse OP-2001 Driver
Optical mouse - Wikipedia
The amount that the edges of one photograph overhang the other represents the offset between the images, and in the case of an optical computer mouse the distance it has moved. Optical mice capture one thousand successive images or more per second. Depending on how fast the mouse is moving, each image Azona Optical Mouse OP-2001 be offset from the previous one by a fraction of a pixel or as many as several pixels. Optical mice mathematically process these images using cross correlation to calculate how much each successive image is offset from the previous one.
Its sensor would normally share the same ASIC as that used for storing and processing the images. One refinement would be accelerating the correlation process by using information from previous motions, and another refinement would be preventing deadbands when moving slowly by adding interpolation or frame-skipping.
The development of the modern optical mouse at Hewlett-Packard Co. Allen, David Beard, Mark T. Smith, and Barclay J.
Tullis were awarded US Patents Azona Optical Mouse OP-2001, and 5, for 2-dimensional optical navigational i. This is the freehand scanning concept used in the HP CapShare handheld scanner. By describing an optical means that explicitly overcame the limitations of wheels, balls, and rollers used in contemporary computer mice, the optical mouse was anticipated.

Baumgartner, Thomas Hornak, Mark T. Tullis, where surface feature image sensing, image processing, and image correlation was realized by an integrated circuit to produce a position measurement.
How do optical mice work?
Improved precision of 2D optical navigation, needed for application of optical navigation to precise 2D measurement of media paper advance in HP DesignJet large format printers, was further refined in Azona Optical Mouse OP-2001 Patent 6, awarded in to Raymond G. While the reconstruction of the image in the document scanning application Allen et al. The color of the optical mouse's LEDs can vary, but Azona Optical Mouse OP-2001 is most common, as red diodes are inexpensive and silicon photodetectors are very sensitive to red light.
Laser mice[ edit ] Although invisible to the naked eye, the light produced by this laser mouse is captured as the color purple because CCDs are sensitive to a broader light wavelength range than the human eye. The laser mouse uses an infrared laser diode instead of an LED to illuminate the surface beneath their sensor. This mouse uses Azona Optical Mouse OP-2001 small infrared laser instead of Azona Optical Mouse OP-2001 LED and has significantly increased the resolution of the image taken by the mouse.
The laser illumination enables superior surface tracking compared to Azona Optical Mouse OP-2001 optical mice. To do this, the mouse dims or blinks the laser or LED when in standby mode each mouse has a different standby time.

A typical implementation by Logitech has four power states, where the sensor is pulsed at different rates per second: Examples of mice which sacrifice power-saving in favor of performance are the Logitech G5 and the Razer Copperhead. Optical versus mechanical mice[ edit ] The Logitech iFeel optical mouse uses a red LED to project light onto the tracking surface.
Unlike mechanical mice, whose tracking mechanisms can become clogged with lint, optical mice have no Azona Optical Mouse OP-2001 parts besides buttons and scroll wheels ; therefore, they do not require maintenance other than removing debris Azona Optical Mouse OP-2001 might collect under the light emitter.
Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves Azona Optical Mouse OP-2001 cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly.
Optical mice have several benefits over wheeled mice: No moving parts means less wear and a lower chance of failure. There's no way for dirt to get inside the mouse and interfere with the tracking sensors. Increased tracking resolution means smoother response.
They don't require a special surface, such as a mouse pad. The original optical-mouse Azona Optical Mouse OP-2001 bounced a focused beam of light off a highly-reflective mouse pad onto a sensor. The mouse pad had a grid of dark lines.
