NEC announced that it has developed a mobile phone document viewer, which enables quick, high-quality display of e-mail attachments, even those comprised of rich media contents such as images and charts, on a user's mobile phone. Through its utilization, office documents can be viewed outside of the office at a quality equivalent to that on a desktop PC, allowing workers to communicate and execute quick decisions even while on the move. This technology can also be used to view manuals or magazines, and is expected to fulfill a broad range of viewing needs.

Mainly enabled by NEC's newly developed, proprietary image data format technology, the viewer achieves the speedy display of images on a mobile phone.
Its main features are as follows:

1. Its easy adaptation to a range of mobile phones is expected as it is coded by Java. 
2. The data format technology allows the display of digital documents/images after they are generated and converted on the server. Moreover, as all digital documents are converted to a format suitable for display on a mobile phone with NEC's data format technology, the speed at which documents containing multiple images or charts are displayed is faster than that of a mobile phone PDF viewer. 
3. The image compression method developed by NEC enables acceleration of the display speed by double that as compared with JPEG methods due to a lighter processing load. This new compression method allows display of both text and images at a quality equivalent to that on a PC as unlike conventional compression methods, it causes little deterioration in image quality. It also enables high quality enlargement or reduction of documents.

With a working society that is ever increasingly dependent on e-mail and the transmission of huge volumes of data and text to execute their daily duties, the need to enable viewing of such data on mobile terminals at locations outside of the office is on the rise. Currently, however, many issues still exist toward achieving this goal. NEC has been carrying out R&D in this area for several years and with this breakthrough has succeeded in the development of a mobile phone document viewer that enables viewing of such documents through the development of NEC's proprietary image format and quick image transfer technology.

It is expected that this document viewer will contribute to increased efficiency in working style and business output. NEC will continue to develop this technology towards its early commercialization.
