An image (from Latin Latin or sometimes Roman is an Italic language originally spoken in Latium and Ancient Rome. Although often considered a dead language, in view of the fact that it has no native speakers, a small number of scholars can fluently speak it and it continues to be taught in schools and universities and has been, and currently is, used in the process of imago) is an artifact, for example a two-dimensional picture, that has a similar appearance to some subject In philosophy, a subject is a being that has subjective experiences, subjective consciousness or a relationship with another entity . A subject is an observer and an object is a thing observed. This concept is especially important in continental philosophy, where 'the Subject' is a central term in debates over human autonomy and the nature of the—usually a physical object or a person A person is any individual human being. The direct plural term is "persons." The term people is the general plural of "person," and is used to refer to person plurally in a range from 'a few persons' up to 'all people' (cf. humanism). "People" is often used to refer to an entire nation or ethnic group, and in this.

Characteristics
Images may be two-dimensional In mathematics and physics, the dimension of a space or object is informally defined as the minimum number of coordinates needed to specify each point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two, such as a photograph A photograph is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and, screen display, and as well as a three-dimensional, such as a statue A statue is a sculpture in the round representing a person or persons, an animal, or an event, normally full-length, as opposed to a bust, and at least close to life-size, or larger. Its primary concern is representational. They may be captured by optical Optics is the branch of physics which studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation devices—such as cameras A camera is a device that records/stores images. These images may be still photographs or moving images such as videos or movies. The term camera comes from the camera obscura , an early mechanism for projecting images. The modern camera evolved from the camera obscura, mirrors A mirror is a shiny object with at least one reflective surface. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image, lenses A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens consists of a single optical element. A compound lens is an array of simple lenses with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is, telescopes A telescope is an instrument designed for the observation of remote objects by the collection of electromagnetic radiation. The first known practically functioning telescopes were invented in the Netherlands at the beginning of the 17th century. "Telescopes" can refer to a whole range of instruments operating in most regions of the, microscopes A microscope is an instrument to see objects too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope, etc. and natural objects and phenomena, such as the human eye Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms complex neural pathways exist that connect the eye, via the optic nerve to the visual cortex and other areas of the brain. Complex optical systems with resolving or water surfaces.
The word image is also used in the broader sense of any two-dimensional figure such as a map A map is a visual representation of an area-a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes, a graph In computer science, a graph is an abstract data structure that is meant to implement the graph concept from mathematics, a pie chart A pie chart is a circular chart divided into sectors, illustrating proportion. In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. When angles are measured with 1 turn as unit then a number of percent is identified with the same number of centiturns. Together,, or an abstract painting Abstract art uses a visual language of form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. In this wider sense, images can also be rendered manually, such as by drawing Drawing is a visual art that makes use of any number of drawing instruments to mark a two-dimensional medium. Common instruments include graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, chalk, pastels, markers, stylus, or various metals like silverpoint. An artist who practices or works in drawing may be, painting Painting is the practice of applying paint, pigment, color or other medium to a surface . The application of the medium is commonly applied to the base with a brush but other objects may be used. In art the term describes both the act and the result which is called a painting. Paintings may have for their support such surfaces as walls, paper,, carving, rendered automatically by printing Printing is a process for reproducing text and image, typically with ink on paper using a printing press. It is often carried out as a large-scale industrial process, and is an essential part of publishing and transaction printing or computer graphics Computer graphics are graphics created using computers and, more generally, the representation and manipulation of image data by a computer technology, or developed The visual arts are art forms that create works which are primarily visual in nature, such as ceramics, drawing, painting, sculpture, architecture, printmaking, modern visual arts , design and crafts. These definitions should not be taken too strictly as many artistic disciplines (performing arts, conceptual art, textile arts) involve aspects of by a combination of methods, especially in a pseudo-photograph In the UK, the Criminal Justice and Public Order Act 1994 amended the Protection of Children Act 1978 so as to define the concept of an "indecent pseudo-photograph of a child".
A volatile image is one that exists only for a short period of time. This may be a reflection of an object by a mirror, a projection of a camera obscura The camera obscura is an optical device that projects an image of its surroundings on a screen. It is used in drawing and for entertainment, and was one of the inventions that led to photography. The device consists of a box or room with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside where it, or a scene displayed on a cathode ray tube The Cathode Ray Tube is a vacuum tube containing an electron gun (a source of electrons) and a fluorescent screen, with internal or external means to accelerate and deflect the electron beam, used to create images in the form of light emitted from the fluorescent screen. The image may represent electrical waveforms (oscilloscope), pictures (. A fixed image, also called a hard copy In information handling, a hard copy is a permanent reproduction, or copy, in the form of a physical object, of any media suitable for direct use by a person , of displayed or transmitted data. Examples of hard copy include teleprinter pages, continuous printed tapes, facsimile pages, computer printouts, and radio photo prints, is one that has been recorded on a material object, such as paper Paper is a thin material mainly used for writing upon, printing upon or for packaging. It is produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets or textile A textile is a flexible material consisting of a network of natural or artificial fibres often referred to as thread or yarn. Yarn is produced by spinning raw wool fibres, linen, cotton, or other material on a spinning wheel to produce long strands. Textiles are formed by weaving, knitting, crocheting, knotting, or pressing fibres together by photography Photography is the process, activity and art of creating still or moving pictures by recording radiation on a radiation-sensitive medium, such as a photographic film, or an electronic sensor. Photography uses foremost radiation in the UV, visible and near-IR spectrum. For common purposes the term light is used in stead of radiation. Light or digital processes.
A mental image A mental image is an experience that, on most occasions, significantly resembles the experience of perceiving some object, event, or scene, but occurs when the relevant object, event, or scene is not actually present to the senses. There are sometimes episodes, particularly on falling asleep and waking up (hypnapompic), when the imagery, being of exists in an individual's mind: something one remembers or imagines. The subject of an image need not be real; it may be an abstract concept, such as a graph In mathematics and computer science, graph theory is the study of graphs: mathematical structures used to model pairwise relations between objects from a certain collection. A "graph" in this context refers to a collection of vertices or 'nodes' and a collection of edges that connect pairs of vertices. A graph may be undirected, meaning, function, or "imaginary" entity. For example, Sigmund Freud Sigmund Freud , born Sigismund Schlomo Freud (6 May 1856 – 23 September 1939), was an Austrian neurologist who founded the psychoanalytic method of psychiatry. Freud is best known for his theories of the unconscious mind and the defense mechanism of repression, and for creating the clinical practice of psychoanalysis for treating psychopathology claimed to have dreamed purely in aural-images of dialogs. The development of synthetic acoustic technologies and the creation of sound art Sound art is a diverse group of art practices that considers wide notions of sound, listening and hearing as its predominant focus. There are often distinct relationships forged between the visual and aural domains of art and perception by sound artists have led to a consideration of the possibilities of a sound-image made up of irreducible phonic substance beyond linguistic or musicological analysis.
A still image is a single static image, as distinguished from a moving image (see below). This phrase is used in photography Photography is the process, activity and art of creating still or moving pictures by recording radiation on a radiation-sensitive medium, such as a photographic film, or an electronic sensor. Photography uses foremost radiation in the UV, visible and near-IR spectrum. For common purposes the term light is used in stead of radiation. Light, visual media Electronic media are media that use electronics or electromechanical energy for the end user to access the content. This is in contrast to static media (mainly print media), which are most often created electronically, but don't require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to and the computer industry Computer industry is a collective term used to describe the whole range of businesses involved in developing computer software, designing computer hardware and computer networking infrastructures, the manufacture of computer components and the provision of information technology services to emphasize that one is not talking about movies, or in very precise or pedantic technical writing such as a standard Standardization or standardisation is the process of developing and agreeing upon technical standards. A standard is a document that establishes uniform engineering or technical specifications, criteria, methods, processes, or practices. Some standards are mandatory while others are voluntary. Voluntary standards are available if one chooses to.
A film still A film still, sometimes called a publicity still, is a photograph taken on the set of a movie or television program during production by a movie stills photographer, primarily used for promotional purposes is a photograph taken on the set of a movie or television program during production, used for promotional purposes.
Moving image
A moving image is typically a movie (film A film, also called a movie or motion picture, is a story conveyed with moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry), or video Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion, including digital video Digital video is a type of video recording system that works by using a digital rather than an analog video signal. The terms camera, video camera, and camcorder are used interchangeably in this article. It could also be an animated display such as a zoetrope A zoetrope is a device that produces an illusion of action from a rapid succession of static pictures. The term zoetrope is from the Greek words ζωή - zoe, "life" and τρόπος - tropos, "turn". It may be taken to mean "wheel of life".
