Mounted in ADAS Applications, Nighttime Pedestrian Detection

Toshiba Corporation announced today that it has expanded its TMPV760 series lineup of image recognition processors for automotive applications by launching the TMPV7602XBG, which is suited for monocular cameras in advanced driver assistance system (ADAS) applications. Samples of the TMPV7602XBG will be shipped starting March 2016, with mass production scheduled to commence in January 2018.

The TMPV7602XBG can recognize images captured by monocular cameras mounted on vehicles at high speed and with low power consumption. This product recognizes information necessary for safe driving, such as pedestrians, vehicles, lane markings, traffic signs, road surface markings, and traffic lights in the vicinity.

The European New Car Assessment Programme (Euro NCAP) has published updated safety rating guidelines, and the test item section stipulates that the following systems must be adopted by 2018: "a system that detects pedestrians and avoids collisions in bright daylight and dim lighting conditions" and "a system that detects cyclists and avoids collisions". Toshiba's new image recognition processor is targeted at ADAS applications that need to meet these new requirements.



The TMPV7602XBG inherits the excellent nighttime object recognition capabilities of the TMPV760 series while optimizing the circuit to reduce power consumption and minimize package size (17.0mm×17.0mm, 521 balls, and BGA 0.65mm pitch), enabling the monocular camera to have a single video input channel. The TMPV7602XBG allows for reduced heat generation from the camera within the vehicle and smaller package size.

ADAS including autonomous braking and lane-keeping assist functions are increasingly being deployed across a wide range of vehicles, from compact sedans to high-end luxury cars. As adoption of safety driving support systems increases, Toshiba is committed to continuing development of new image recognition processors.



Recognition Accuracy Particularly Enhanced at Night

The TMPV7602XBG inherits the excellent nighttime object recognition capabilities of the TMPV760 series. The TMPV7602XBG integrates Toshiba's color-based Enhanced CoHOG (Co-occurrence of Oriented Gradients) accelerator, which supports four sets of feature descriptors including CoHOG image feature descriptor and Color-CoHOG color-based image feature descriptor. CoHOG is a Histogram of Oriented Gradients technology developed by Toshiba, and therefore the new product exhibits particularly higher recognition accuracy at night or when there is little brightness difference between an object and its background.

Reducing Camera Module Size by Minimizing Package and Reducing Power Consumption
The TMPV7602XBG optimizes the circuit to minimize package size (17.0mm×17.0mm, 521 balls, and BGA 0.65mm pitch), enabling miniaturization of ADAS monocular camera modules. The new product is expected to consume 50% less power than the TMPV7608XBG, the existing TMPV760 series product. Additionally, a newly integrated power management unit controls each functional block when switching between power-saving mode or normal mode, enabling efficient power management.
