Epson Perfection 4490 Photo
High speed scanning
Enhanced scanning speed by incorporating innovative technologies
With numerous technologies that enhance the speed of data processing and transmission, the Perfection 4490 Photo has been designed to provide outstanding quality scanning without compromising on speed. The first of these technologies is a high-speed PC-centric ASIC (Application-Specific Integrated Circuit) that processes image data at speeds much greater than previous models.
With a newly designed moving carriage type TPU, the Perfection 4490 Photo achieves brighter and more evenly dispersed luminance, which are essential requirements in improving scan uniformity and film/negative scanning speed.
To improve negative scanning speed even further, the Perfection 4490 Photo incorporates an innovative bluish lamp, which compensates for the fact that in negative scanning, the capture of blue data takes significantly longer than green and red. The result of the Perfection 4490 Photo's bluish lamp is a shorter exposure time required for the accurate capture of the blue image data.
Adding even further to the high speed capabilities of the Perfection 4490 Photo is its standard USB 2.0 port. Aside from providing broad connectivity support, the USB 2.0 port ensures a high speed transmission rate of the massive amounts of scanned image data captured and processed by the scanner.
