Toshiba Corp exhibited a technology to recognize cars running diagonally behind and display their images on the two monitors used as side mirrors by using "Visconti," an image processing LSI for vehicles, at Automotive Engineering Exposition 2008.

"We suggested one of the applications of the Visconti," Toshiba said.

The Visconti is used for the "Intelligent Night Vision System," a night-vision system mounted on Honda's high-grade sedan "Legend."

In the demonstration, the images on the two monitors were regarded as the scenes reflected on side mirrors. And the vehicles running from behind in the next lanes were shown on the monitors.

The distance to the approaching car is calculated by the image-recognition technology, and the color of the line shown on the monitor changes depending on the distance. As the distance becomes shorter, the color changes from green to red via yellow. In the demo, the area that the Visconti was processing was surrounded by a white line, and the horizontal line was drawn in blue.

Toshiba also exhibited a circuit board that conducts image processing. In addition to the Visconti, which is used to recognize images, the circuit board is mounted with "Cycrone II," a low-price FPGA developed by Altera Corp, which is used to display 640 × 480 color VGA images. The Visconti does not have a function of displaying those images.
