Visual sensor networks are most useful in applications involving area surveillance, tracking, and environmental monitoring.Of particular use in surveillance applications is the ability to perform a dense 3D reconstruction of a scene and storing data over a period of time, so that operators can view events as they unfold over any period of time (including the current moment) from any arbitrary ...
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens, photographic lens or photographic objective is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
The first Japanese pentaprism SLR was the 1955 Miranda T, followed by the Asahi Pentax, Minolta SR-2, Zunow, Nikon F and the Yashica Pentamatic. Some SLRs offered removable pentaprisms with optional viewfinder capabilities, such as the waist-level finder , the interchangeable sports finders used on the Canon F1 and F1n; the Nikon F, F2, F3, F4 ...
MILCs, or mirrorless cameras for short, come with various sensor sizes depending on the brand and manufacturer, these include: a small 1/2.3 inch sensor, as is commonly used in bridge cameras such as the original Pentax Q (more recent Pentax Q versions have a slightly larger 1/1.7 inch sensor); a 1-inch sensor; a Micro Four Thirds sensor; an ...
[2] [3] [4] The chronophotographic gun invented by Étienne-Jules Marey. The chronophotographic gun was invented in 1882 by Étienne-Jules Marey, a French scientist and chronophotographer. It could shoot 12 images per second and was the first invention to capture moving images on the same chronomatographic plate using a metal shutter. [5]

Early smart camera (ca. 1985, in red) with an 8MHz Z80 compared to a modern device featuring Texas Instruments' C64 @1GHz. A smart camera is a machine vision system which, in addition to image capture circuitry, is capable of extracting application-specific information from the captured images, along with generating event descriptions or making decisions that are used in an intelligent and ...
The act of making a 2D image with a mobile phone camera.The display of the phone shows the photograph that will be made and stored.. An image is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving or sculpture.
