An image trigger initiates the capture of single or multiple frames of a digital camera by analysing the signals of its sensor. For capturing and analysing of fast moving objects (e.g. as in quality control of production lines) modern high speed cameras are frequently used. Typically the initiation of an image-series starts as soon as the ...
Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. [3] High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.
feature based search task. Feature search (also known as "disjunctive" or "efficient" search) [6] is a visual search process that focuses on identifying a previously requested target amongst distractors that differ from the target by a unique visual feature such as color, shape, orientation, or size.

Every time lenses are changed, dust may enter the camera body and settle on the image sensor. Digital single-lens reflex cameras (DSLR) are particularly vulnerable to this issue, since the interior of the camera is exposed during lens changes unlike other forms of digital cameras, and the image sensor is fixed, unlike a film camera. Even the ...
Computational photography can improve the capabilities of a camera, or introduce features that were not possible at all with film-based photography, or reduce the cost or size of camera elements. Examples of computational photography include in-camera computation of digital panoramas , [ 6 ] high-dynamic-range images , and light field cameras .
New consumer digital cameras with CCD sensors stopped being released in the early 2010s, and the few that offered USB charging only supported it via a non-standard cable. [42] Proprietary cables , chargers, and batteries can be difficult to come by, especially when discontinued, which makes support for standard AA or AAA batteries (especially ...
A technique for allowing a camera to be pre-focussed to a defined spot, and the exposure is only made when a subject is in focus at that spot. Also called trap focus. CMOS: Complementary metal oxide semiconductor. A semiconductor technology, used to create photosensor arrays for some digital cameras. [4] CMYK: CMYK color model. A subtractive ...
Electronic by nature, most digital cameras are instant, mechanized, and automatic in some or all functions. Digital cameras may choose to emulate traditional manual controls (rings, dials, sprung levers, and buttons) or it may instead provide a touchscreen interface for all functions; most camera phones fall into the latter category.
