Film Grain Noise Algorithm. In film radiography noise is caused by scatter, is often referred to as graininess and can be corrected by using a finer film. Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise.it can be produced by the image sensor and circuitry of a scanner or digital camera.image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector.
Examples include the faint static of analog video, compression artifacts from digital cameras, halftone patterns from scanned prints, ccd noise from digital image sensors, and the characteristic speckle pattern of chemical photography, known as film grain. Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise.it can be produced by the image sensor and circuitry of a scanner or digital camera.image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector. It’s often added to images to create a mood or tie.

In digital techniques, a number on a brightness scale is In dr noise is caused by scatter, undesired radiation and other electronic effects that vary by the type of detector.
