Denso has developed a new monocular forward camera for improved night vision, using Sony’s high-sensitivity 1.27M-pixel image sensor and Toshiba’s new advanced image recognition processor.
Denso has developed a new vision sensor, released in 2018 and featured in the Toyota Alphard and Vellfire. This forward camera, working in conjunction with a millimetre-wave radar sensor, improves pedestrian and cyclist detection, as well as recognition of road signs and driving lanes, even at night. When obstacles such as these are detected and identified, the car’s emergency braking system can be automatically activated.
The monocular camera, manufactured by Denso in Japan, is 25% smaller and uses 30% less components and parts than the previous model. Also, for the first time in an automotive camera, we have found a Sony CMOS image sensor. This 1.27M-pixel sensor offers higher sensitivity to the near-infrared sensor, and the low-light use-designed lens housing improves the camera’s night-time identification of other road users and road signs. Regarding processing, the chipset is composed of a Sony image signal processor, a Toshiba image recognition processor, and a Renesas MCU.
Based on a complete teardown analysis, this report includes the camera’s bill-of-materials (BOM) and manufacturing cost. Also included is a physical analysis of the CMOS image sensor and the processors (Toshiba and Renesas), along with a complete cost analysis and estimated sales price.
