No. 184: NEC’s new image conversion technology (November 10, 2010)

NEC developed the image conversion technology that converts low-resolution image to high definition image in a short time. The new technology can convert a one-hour analog video to a high definition image video in 10 hours, one seventieth of the current processing time. It can be used to increase the image resolution of security camera. In the initial stage, however, NEC wishes to put it into practical use for broadcasting stations in a few years. The color quality deteriorates and noise comes up if a low-resolution image is projected on the high definition screen. A clear image can be created if resolution can be restored in image processing. The current technology uses the system to uncompress one high definition frame among multiple frames that construct an image. It takes more than one month for the current technology to convert a one-hour image into high definition image, but NEC improved the calculation method and successfully shortened the necessary time to about 10 hours. It will be possible to convert past analog sports programs and dramas into high definition image videos. Moreover it can draw the profile of a criminal if it is applied to the image of security camera. NEC plans to install it in the PC in the future.
