Commencement of Sales of TE3610PF Dynamic Range Compression LSI


Tokyo Electron Device Limited (Headquarters: Kanagawa-ku, Yokohama, President: Toshiaki Sunagawa) has commenced sales of the TE3610PF LSI. The device is based on two image processing technologies developed by Apical Limited (Headquarters: London, United Kingdom, CEO:Dr. Michael Tusch): iridix®, which implements pixel-by-pixel dynamic range compression, and sinter®, which is an advanced noise reduction core. The dynamic range compression function can produce images with a most natural appearance similar to that seen by the human eye while the noise reduction function reduces sensor noise and improves the efficiency of compression techniques such as JPEG and MPEG.


The demand for high quality images in video equipment has strengthened in recent times. This desire for better image quality extends to security equipment such as surveillance cameras and vehicle-mounted cameras, and the ability to view scenes reliably even when reflections, dark regions, or other impediments are present is becoming increasingly important.


Apical's iridix image processing technology is a type of dynamic range compression that uses a "proprietary algorithm which mimics the action of the human retina". The method uses research into the human visual system (HVS) to model how the retina automatically adjusts the dynamic range of an image and works by adjusting the brightness of each pixel in realtime with reference to the local area within the frame. The technology can reproduce images in the most natural way regardless of the environment in which the image was captured. iridix is generally recognized to be very sophisticated technology of its kind so far developed.


The standard form of dynamic range adjustment uses gamma correction to apply non-linear gain to an image. Such global processing progressively reduces contrast as dynamic range of the scene increases, leading to substantial loss of information and frequently unacceptable images. When using iridix dynamic range compression, however, the optimum tone curve is determined individually for each pixel which allows the image to be reproduced in a way similar to that seen by the human observer.


Information content and local contrast is always preserved under all conditions.


Because the TE3610PF uses “sinter” noise reduction technology in addition to iridix, it reduces sensor noise prior to image compression and improves the efficiency of JPEG and MPEG compression.


The TE3610PF connects to the final stage of the AFE (analog front end) (see Figure 1: Example application for a surveillance camera) so as to apply correction to the RAW data which has the highest information content and achieve the maximum possible dynamic range compression benefits.


The new LSI is aimed primarily at use in digital cameras and in security equipment such as surveillance cameras and vehicle-mounted cameras. Sales will be aimed at Japan in particular as well as markets in China, Taiwan and North America, and the sales target for the 2009 financial year is 150 million yen.
