However, maintaining focus doesnt guarantee a sharp image, as there is a short time lag between the release of the shutter and the capture of the picture. To solve this problem, the focus tracking system is a predictive system that uses special algorithms to forecast the position of the subject at the moment the image is captured. The prediction is based on a measurement of the subjects movement and speed. Simple predictive tracking is very effective for pictures of a subject moving at constant speed toward the camera, but to provide maximum focusing performance for a subject that abruptly changes direction at high speed, or a subject with low contrast, moving randomly, the AF system must accumulate subject location data using multiple focus areas. The AF modules built into selected Nikon D SLRs have as many as 5. To realize high precision AF for high speed continuous shooting of a fast moving subject, the processing speed of the AF cycle is vital.

When the user is in either AF A or AF C focus modes, the user selects the focus point. As long as the shutter button is kept pressed halfway, if the subject moves after the camera has focused, the camera uses 3.

In. Glossary ,Summary An aberration prevents light from being brought into sharp focus. The ideal image by lenses especially photographic lenses, must fulfill three key conditions, namely, 1. In reality, however, light refraction by the lens causes a variety of defects in the image, called aberration. The five most common types in aberration are SEIDELs five aberrations, which occur even with monochromatic single wavelength light. In addition, there are also two types of chromatic aberrations, which are caused by more than one frequency. It is impossible to eliminate them all, but in the lens design process, they can be controlled and balanced to provide the best possible result for that lens and application.

DJI Rolls Out Local Data Mode for Drones After US Army Ban Over Unknown Cyber VulnerabilitiesWeeks after the US Army told personnel to immediately shelve all drones made by Chinese manufacturer DJI, citing unspecified cyber vulnerabilities associated with DJI products, the company has introduced a new local data mode for its apps. We are creating local data mode to address the needs of our enterprise customers, including public and private organizations that are using DJI technology to perform sensitive operations around the world, company VP for Policy and Legal Affairs Brendan Schulman said in a press release, per Tech. Crunch. DJIs apps use the internet to update maps, restricted flight zones and other relevant data, as well as have an optional feature to sync with the companys database to store flight data. The new local mode disables all of those features. Its clear even by the companys own admission the timing with the Army announcement is not a coincidence, though Tech. Crunch reported DJI says the local mode was in development for several months and was not originally spurred by US brass. Were not responding to the Army, which has never explained its concerns to us, DJI communications director for North America Adam Lisberg told Tech. Crunch. We announced it today because enterprise customers with serious data security have made clear they need something like this for a while, and the Army memo reinforced that concern for them. The military has declined to reveal the security vulnerabilities, presumably for operational security reasonssmall drones like those manufactured by DJI are already in limited deployment with the US military, and are widely used by some guerilla forces that oppose them like ISIS extremists. DJI also says the Army has not clued them in. But its not clear that disabling internet access on a drones control app would plug whatever hole the military suspects it found anyhow. Its possible theres a vulnerability in the way DJI drones remotely interface with its controller, or a way of tricking the drone into leaking data to another user without breaking into the app at all. Its also possible the military sees the risk of a drone being hacked into as minimal, but someone didnt like the idea of any of its data possibly being sent to a private manufacturer in another country, or of US personnel using a commercial drone system at all. US military use is not Chinese manufacturer DJIs core target market, though. That the Army uses commercial drones in any capacity at all speaks to a need which will likely be filled in the future by military drones built to specification for use in the field and elsewhere.
