Visconti™ Image Recognition Processor

Related Information

The powerful Visconti™ Series image recognition processor ICs are used in camera-based vision systems for advanced driver assistance systems (ADAS). Visconti changes the way people drive by detecting and recognizing target objects such as humans, faces, hands, vehicles and processes image data from multiple camera inputs frame-by-frame and then outputs results to an LCD panel. The Visconti Series can monitor and detect a wide range of driving conditions:

  • Forward Vehicle Detection and Collision Warning
  • Forward and Backward Collision
  • Real-time Traffic Lines
  • Lane Departure Warning
  • Rear and Front Pedestrian Detection
  • Left/Right Turn Awareness
  • Obstacle Vehicle Detection
  • Traffic Sign Detection
  • Top-view Parking Assistance
  • Driver authentication and monitoring
Features
  • Toshiba launches its new TMPV7608XBG, which will simplify implementation of next-generation Advanced Driver Assistance Systems (ADASs), targeting 2018 European New Car Assessment Program (Euro NCAP) applications. ADAS capabilities supported by the TMPV7608XBG include autonomous emergency braking, traffic signal recognition, lane departure warning/lane keeping assist, high beam assistance and forward collision warning—many of which are included in the Euro NCAP safety ratings criteria. The TMPV7608XBG integrates two new enhanced CoHOG accelerators that provide high image recognition accuracy especially in low light and night-time condition.
  • Toshiba launches its new TMPV7502XBG image recognition processor for advanced driver assistance systems (ADAS), which identify and recognize oncoming and surrounding vehicles and pedestrians from in-vehicle cameras. For use in ultra-small camera modules, and offering fast, accurate image detection, the TMPV7502XBG is capable of performing multiple detections simultaneously, such as a lane departure warning, collision warning, pedestrian detection and traffic sign recognition. Its smaller package size (11mm x 11mm) enables it to be integrated directly into the camera module, simplifying installation and reducing cost.
  • The Visconti Series incorporates Toshiba's original image processing accelerators using Histogram of Oriented Gradients (HOG) features, enabling real-time pedestrian detection both in night time and daytime. HOG features are suitable for detection of humans due to its robustness regardless of lighting changes or small deformations.
  • The Visconti2 and 3 Series support high-resolution color cameras suitable for applications requiring color recognition, such as detection of traffic lights and signs.
  • Up to four cameras can be simultaneously connected to the Visconti2 and 3 Series making it suitable for a bird's-eye view parking assistance system that uses images synthesized from image data captured by four cameras.
  • The Visconti2 and 3 Series incorporate four image processor cores operating at 0.266 GHz, and up to six image processing accelerators, enabling fast object detection with enhanced performance. At 0.266 GHz, each image processor core achieves computing performance equivalent to that of 3 GHz notebook PC processors and realizes low-power consumption of less than 2W.
  • The Visconti3 Series is backward compatible with the Visconti2 series and can run the OS and other software needed for enhanced connectivity with car navigation, smartphone and cloud applications by adding the ARM® Cortex™-A9 MPCore™.
  • The Visconti3 Series incorporates a single/double-precision Floating Point Unit (FPU) that simplifies optimization of the imaging algorithms so that software developers can reduce their overall design time.
