Image sensorAn image sensor or imager is a sensor used for imaging. It converts light into electrical signals, small bursts of current in proportion to the light intensity. The pattern of electrical signals conveys the information in the image.
PixelIn digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element of a raster image. In a display device, dot matrix printer, or ASCII art a pixel is the smallest element whose output can generally be controlled independently. The concept of a picture element dates to the earliest days of electronic imaging.
Digital cameraA digital camera, also called a digicam, is a camera that uses digital storage to capture images. Most cameras produced since the start of the 21st century are digital, largely replacing cameras that captured images on photographic film or film stock. Many digital cameras are now integrated into mobile devices such as smartphones. However, high-end dedicated digital cameras are still commonly used by professionals.
4K resolution4K resolution is a generic term to refer to any horizontal display resolution of approximately 4,000 pixels. Several different 4K resolutions have been standardized by various organizations, including 4096 × 2160 for digital cinematography, and 3840 × 2160 for digital television. The terms 4K and Ultra HD are used more widely in marketing than 2160p (cf.1080p), and typically refer to motion pictures and video.
Digital imagingDigital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, 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.
ImageAn image or picture 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. Images may be displayed through other media, including a projection on a surface, activation of electronic signals, or digital displays; they can also be reproduced through mechanical means, such as photography, printmaking, or photocopying.

IntegerAn integer is the number zero (0), a positive natural number (1, 2, 3, ...), or the negation of a positive natural number (−1, −2, −3, ...). The negations or additive inverses of the positive natural numbers are referred to as negative integers.
DVDDigital optical disc data storage formatDVD (Digital Video Disc or Digital Versatile Disc) is a digitaloptical discdata storage format. It was invented and developed in 1995 and first released on November 1, 1996, in Japan. The medium can store any kind of digital data and has been widely used to store video programs (watched using DVD players), software and other computer files.
DV (video format)DV (from Digital Video) is a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. It includes the cassette formats DV, MiniDV, DVCAM, DVCPro, DVCPro50, DVCProHD, Digital8, and Digital-S. DV has been used primarily for video recording with camcorders in the amateur and professional sectors. DV was designed to be a standard for home video using digital data instead of analog.
Digital8Digital8 (or D8) is a consumer digital recording videocassette for camcorders developed by Sony, and introduced in 1999. The Digital8 format is a combination of the earlier analog Hi8 tape transport with the digital DV codec. Digital8 equipment uses the same videocassettes as analog recording Hi8 equipment, but the signal is encoded digitally using the industry-standard DV codec, which means it has identical digital audio and digital video specifications compared with DV.
Angular resolutionAngular resolution describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution. It is used in optics applied to light waves, in antenna theory applied to radio waves, and in acoustics applied to sound waves.Pixel densityPixels per inch (ppi) and pixels per centimetre (ppcm or pixels/cm) are measurements of the pixel density of an electronic image device, such as a computer monitor or a television set's display, or image digitizing device such as a camera or image scanner. Horizontal and vertical density are usually the same, as most devices have square pixels, but differ on devices that have non-square pixels.*As an Amazon Associate I earn from qualifying purchases.
