Image recognition processor for small automotive cameras

May 28, 2014 // By Graham Prophet
Toshiba’s launch of a cost-efficient image recognition processor will enable implementation of small-scale driver assistance systems.

Expanding its line-up of TMPV750 image recognition processors is Toshiba’s TMPV7502XBG, which has been designed for small-size camera modules. TMPV7502XBG is assembled in a package measuring 11 by 11 mm with power consumption of 0.6W (Typ.).

TMPV7502XBG can be used in advanced driver assistance systems (ADAS) that recognise lanes, road signs, vehicles and pedestrians from images collected by cameras positioned around the car and in electronic side mirrors. The image recognition processor uses Toshiba’s 32-bit RISC CPU MeP (Media embedded Processor) and two Toshiba multi-core Media Processing Engines (MPE).

It incorporates 1 channel video input interface and optimised circuit configuration to enable the rapid detection of multiple vehicles, signs and people. This fast and highly accurate detection is made possible by the incorporation of CoHOG (Co-occurrence Histograms of Oriented Gradients) hardware detection technology and four image processing accelerators.

Rated for operation at ambient temperatures of -40°C to 85°C, TMPV7502XBG is housed in a 324-pin P-LFBGA package measuring 11mm by 11mm with 0.5mm ball pitch.
