Digital image processing. Digital image processing is the use of a digital computer to process digital images through an algorithm. [1][2] As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data ...
The history of digital photography began in the 1950s. In 1951, the first digital signals were saved to magnetic tape via the first video tape recorder. [3] Six years later, in 1957, the first digital image was produced through a computer by Russell Kirsch. It was an image of his son. [4] First digital image ever created, by Russell Kirsch. It ...
Digital image. A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively.

1975 – Bryce Bayer of Kodak develops the Bayer filter mosaic pattern for CCD color image sensors. 1976 – Steadicam becomes available. 1986 – Kodak scientists invent the world's first megapixel sensor. 1987. Canon releases the first camera for its fully electronic autofocus EF lens mount, the EOS 650 [20]
Digital imaging. Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, [1] such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images.
An image scanner (often abbreviated to just scanner) is a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image. The most common type of scanner used in offices and in the home is the flatbed scanner , where the document is placed on a glass window for scanning.
Digital single-lens reflex cameras (DSLR) is a camera with a digital sensor that utilizes a reflex mirror to split or direct light into the viewfinder to produce an image. [63] The reflex mirror finds the image by blocking light to the camera's sensor and then reflecting it into the camera's pentaprism which allows it to be seen through the ...
Image analysis. Image analysis or imagery analysis is the extraction of meaningful information from images; mainly from digital images by means of digital image processing techniques. [1] Image analysis tasks can be as simple as reading bar coded tags or as sophisticated as identifying a person from their face.
