DjVu (pronounced “deja vu”) is an image compression technology developed since 1996 at AT&T Labs. Its purpose was to enable the scanning of the paper documents that include color graphics and/or photographs(that represent significant invested value) and getting them onto the website without compromising on its resolution and satisfactory download speed.
Earlier what used to happen was – At the high resolution necessary to ensure the readability of the text and to preserve the quality of the images, file sizes used to become far too bulky for acceptable download speed. On the other hand, reducing resolution to achieve satisfactory download speed meant forfeiting quality and legibility.
Prior to DjVu, conventional web formats such as JPEG, GIF, and PNG produced prohibitively large image files at decent resolution.
DjVu allows the distribution on the Internet of very high resolution images of scanned documents, digital documents, and photographs. DjVu also enables the content developers to scan high-resolution color pages of books, magazines, catalogs, manuals, newspapers,historical or ancient documents, and make them available on the Web. In short, the information that was previously trapped in hard copy form can now be made available to wide audience via the internet(at present, over 90 percent of the information in the world is still on paper and almost none of that rich content is on the Internet).
Now for reading such content present in the DjVu format over the mobile phones, there’s an application known as the DjVu Reader for the mobile devices running on Symbian OS. DjVu Reader is a free reader application for Symbian S60 3rd and 5th edition mobile devices.
