Toshiba Corp. is set to launch the Visconti2 (TMPV7500) line of image recognition processors targeted at automotive applications.

The Visconti2 (TMPV7500) recognises lanes, vehicles, pedestrians, traffic signs, etc. using camera-based vision systems and will start sampling by November this year and mass production in September next year.

The TMPV7506XBG integrates the company's image processing accelerators suitable for human recognition using HOG (Histogram of Oriented Gradients) features. It can detect pedestrians both in night time and in daytime. Supporting high-resolution colour cameras up to 13 lakh (1.3 million) pixels, the processor recognises not only the tone of the target object but also the colour, enabling detection of traffic lights and signs. As it can connect up to four sets of cameras simultaneously, the TMPV7506XBG is applicable for a bird's-eye view parking assistance system that uses images synthesised from image data captured by four cameras, described Toshiba.


The Visconti2 operates at 266MHz and is geared for automotive applications.

Another line-up within the Visconti2 series is the TMPV7504XBG. Supporting up to two colour cameras, the TMPV7504XBG is suitable for a forward monitoring system simultaneously detecting multiple targets, including vehicles, lanes and traffic signs.

Toshiba intends to expand the image recognition processor business by enhancing these devices for industrial and consumer applications as well as for automotive applications. The target is to sell 20 lakh units annually of the total Visconti processors series in fiscal 2015.

The Visconti2 series incorporates four sets of MPE operating at 0.266GHz, and up to six image processing accelerators, enabling object detection with enhanced performance, said the company. The processors consume less power and achieve computing performance equivalent to that of processors of 3GHz class for notebooks, added Toshiba.

The device operates with ambient temperature of -40°C to 85°C and junction temperature of -40°C to 125°C. When the device comes out, it will be packaged in BGA 516 pins, 27 × 27mm, 1mm pitch.
