Scanners
To transfer a hardcopy document or graphic image to a digital format, you can use a scanner, which captures the image and converts it into a digital file. Additionally, a smartphone or digital camera can capture images of documents, which can then be processed using various apps to create digital files. Other options include multifunction printers that combine printing and scanning capabilities.
Digital images are produced by a variety of devices, including digital cameras, smartphones, and scanners. These devices capture light and convert it into digital data, which can be processed and stored. Additionally, computers with graphic design software can create digital images from scratch. Other devices, such as drones and webcams, also generate digital images for various applications.
A digital scanner is an input device. It captures images or documents and converts them into a digital format for processing. In contrast, a plotter is an output device used for printing, while a monitor and flat panel are also output devices that display visual information.
The conversion of letters, sounds, and images into electrical signals is called digital encoding. This process essentially translates analog data into a digital format that can be easily transmitted and processed by electronic devices.
For example digital computers to edit images, (digital) cameras to obtain images or computers to render them.

A digital photo frame is considered an output device because it displays visual information, specifically images stored in its memory or received via external sources. It converts digital image files into a visual format that users can view and appreciate. By presenting photos in a slideshow or static format, it allows users to enjoy their images without needing a computer or other device.
Digital format refers to the way information is encoded in a digital system, allowing it to be stored, processed, and transmitted electronically. This can include text, images, audio, and video converted into binary code (0s and 1s) that computers can understand. Digital formats enable efficient sharing and manipulation of data across various devices and platforms. Common examples include JPEG for images, MP3 for audio, and PDF for documents.

Devices that do not convert images into digital form include traditional film cameras, which capture images on photographic film, and analog scanners that produce output in physical formats rather than digital. Additionally, print media such as newspapers and magazines do not convert images into digital form, as they produce images directly on paper without digital processing.
