Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis (). [1]
This approach is contrasted to digital image stabilization in which the physical image is allowed to "track" the scene on the CCD by software to produce a stable image. The digital technique requires the pixel count to be increased to allow the image to move on the sensor while keeping reference points within the boundaries of the capture chip.
Image stabilization. Technology to minimize image blurring by camera movement during exposure. See also AS, OS, OIS, OSS, SR, SS, SSI, SSS, VR as brand-specific terms. [10] ISO: A system for quantifying the sensitivity ("speed") of a photographic emulsion, or a solid-state digital-camera's image sensor, to visible light. Normally followed by a ...
Images can be stabilized mechanically with optics mounted on the eye itself, or the image can be continually updated on a display to counteract the effects of eye movements. [5] Because no existing method creates perfect image stabilization, this leaves open the question of whether all perfectly stabilized images disappear completely. [6]
Optical image stabilization allows longer exposures without blurring, despite trembling. The earliest known smartphone to feature it on the rear camera is in late 2012 on the Nokia Lumia 920, and the first known front camera to feature one is on the HTC 10 from early 2016. [10] [11]
Digital image authentication is an issue [34] for the providers and producers of digital images such as health care organizations, law enforcement agencies, and insurance companies. There are methods emerging in forensic photography to analyze a digital image and determine if it has been altered.
Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices . The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone ...
