Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
As the subject moves during the scan, distortions are caused along the axis of the scan head's movement, as it captures different periods of the subject's movement line by line in a manner similar to slit-scan photography; these are forms of strip photography. The artist can use this by aligning the direction of the scan head's movement to ...
It allows users to 'scan' documents (by taking a photo with the device's camera) and share the photo as either a JPEG or PDF. This app is available free of charge on the Google Play Store and the Apple App Store. The app is based on freemium model, with ad-supported free version and a premium version with additional functions.

The slit-scan photography technique is a photographic and cinematographic process where a moveable slide, into which a slit has been cut, is inserted between the camera and the subject to be photographed. More generally, "slit-scan photography" refers to cameras that use a slit, which is particularly used in scanning cameras in panoramic ...
In a raster scan, an image is subdivided into a sequence of (usually horizontal) strips known as "scan lines".Each scan line can be transmitted in the form of an analog signal as it is read from the video source, as in television systems, or can be further divided into discrete pixels for processing in a computer system.

A line-scan camera is a system for producing two-dimensional images using a single sensor element. They normally consist of a rapidly rotating mirror or prism placed in front of the sensor to provide scanning in one direction while the movement of the recording material, often photographic film , provides scanning in the second direction.
