For automated systems to deliver automated driving, they must offer sophisticated, high-precision sensing and recognition performance, encompassing all 360 degrees of the environment around the vehicle. Accordingly, there is considerable demand for image sensors that can help achieve this level of performance and support the development of more advanced automotive camera systems.
The new sensor product achieves the industry’s highest*1 pixel count of 17.42 effective megapixels,*2 enabling high definition capture of far-off objects. Moreover, automated driving systems often use automotive cameras in combination with LiDAR and other sensing systems. While typical CMOS image sensors readout signals output from pixels one vertical line at a time, this product outputs signals horizontally, one row at a time. This means that automotive cameras employing this sensor can more easily synchronize with mechanical scanning LiDAR*4, since their laser beams also scan horizontally. This better synchronization will improve the sensing and recognition capabilities of the automated driving system as a whole.
Furthermore, the new sensors’ improved saturation illuminance, made possible by a proprietary pixel structure, and unique exposure method yield a wide dynamic range of 106 dB even when simultaneously employing high dynamic range (HDR) imaging and LED flicker*5 mitigation. The dynamic range is even higher, at 130 dB, when using dynamic range priority mode. This creative design helps suppress highlight blowouts even in backlit conditions, enabling more precise object capture in road environments with significant differences in brightness, such as tunnel entrances and exits.
*4: LiDAR senses objects using horizontal laser beam scanning delivered by mechanical moving parts. This is a common method used in the automotive sensing domain.
*5: LED flicker that can occur when capturing LED signage or traffic signals.
