![]() ![]() This means that output devices can read image file types and present them to the user in a visual format. More complex algorithms are developed for more complex image types using data processing tools like MATLAB.Ī digital image can not only store information, but it can also convey it. For an image, this is typically done by setting multiple thresholds for different levels of darkness and then marking pixels darker or lighter than that threshold with 1 or 0. Contains encoded informationĪ digital image, like any other file, encodes information found in the real world into a format that machines can understand. Now that we have looked at the meaning of image files let us discuss their defining features: 1. See More: What Is Email Security? Definition, Benefits, Examples, and Best Practices obj, etc., have been developed to contain and convey 3D printing information in 3D files, distinct from image files. In its place, the 90s saw the rise of Joint Photographic Experts Group (.jpeg) and Bitmap (.bmp) formats that would stand the test of time and are still being used today.Īpart from this, several image editing software applications have their own native file extensions, which have evolved to keep pace with the software. This gave rise to the first generation of image file types, as we know them today, outside of industrial use.ĭeluxe Paint used the Interchange File Format (.iff) image file extension, while PC Paintbrush used the PiCture eXchange (.pcx) format. Thanks to these applications, users could now create and save their own images to personal computer storage. Only in the 80s and 90s did software applications like Deluxe Paint and PC Paintbrush start being shipped with computing devices. ![]() At that time, these digital images were still not linked with computing, and it would be many years before personal computing became widespread. The first digital images appeared in the 1960s, driven by advancements in satellite imagery, aerospace research, and medicine. For example, since 2021-2022, we have seen the widespread use of 3D file types that can capture and represent a sense of depth through a three-camera setup and appropriate encoding of the file’s information. Digital images have been around for several decades, and image file types have evolved over the years to keep up with emerging trends. ![]() However, despite their ubiquity, image files are more complex than they may seem on the surface. Productivity apps rely heavily on file types like icons to interact with the user and improve the user experience (UX). The software as a service (SaaS) and web app revolution: With many personal and productivity applications moving online, image files are everywhere.Related to this is the rise of digital ads, which also use embedded images to attract users. The rise of platforms like Instagram and Pinterest: Platforms such as these rely heavily on images (and other types of visuals) to garner traffic.In recent years, image files have become all the more critical for two reasons: At the beginning of the digital learning curve, users experience image files in various formats used in different scenarios – from social media to photography and personal sharing. Image files are probably the most commonly encountered file type by regular computer device users. ![]()
