"Pixon" seems to be a misspelling of "pixel," which is the smallest unit of a digital image. A pixel is a tiny square that is the building block of a digital image on a screen.
The process, which is painless and conducted in the dentist's office, creates a digital video image that is transmitted to a flat-screen panel. It presents a detailed, life-size image that can be moved and spun for viewing at different angles by simply touching the image on screen. The digital image is forwarded to a dental lab so it can produce a permanent denture or crown.
The basic unit of composition of an image on a screen is a pixel. A pixel is the smallest addressable element in a digital image and represents a single point in a raster image. Pixels are used to display images on screens by varying their color and intensity.
An enlarged virtual image is formed on the cinema screen through the projection of light from the film or digital source. This image is created by focusing light rays onto the screen, allowing viewers to see a larger and clearer representation of the content being displayed.
An image made up of light recorded on a censor. Into a digital screen.
Traditional film cameras do not have a screen since the image is recorded onto celluloid and can only be viewed once it has been developed - this process is largely absent of electricity and is a blend of physics and chemistry, unlike modern digital cameras. Digital cameras store the image digitally and almost instantly, meaning you can view the image on the screen. The aspect ratio on digital cameras can vary, so technically the shape and size of the image can vary between 35mm fill cameras and digital. This is particularly noticable when using a lens taking from a 35mm camera and using it on a digital camera. Film cameras provide a far better quality of image that digital photography cannot (realistically) emulate. However, digital is preferred because the ease of producing large images is fast and requires little expereince - unlike film based photography.
Digital frames are electronic devices that are able to take digital image files, such as .jpegs, and play them on their screen. A traditional frame must have a printed photo that is placed inside the frame.
Digital Image Design was created in 1989.
Digital image is depending on the camera resolotion, where optical image depends on the quality of the film. Normally an optical image will be better then a digital image, unless you are using high end digital camera. I hope this helps, Icko www.rtgallery.com
