Automotive Camera Sensor Raises Resolution Bar

Sony’s IMX324 debuts as a new 1/1.7-type stacked CMOS image sensor boasting the industry's highest resolution of 7.42 effective megapixel with a RCCC filter for forward-sensing cameras in advanced driver-assistance systems (ADAS). The sensor is capable of approximately three times the horizontal resolution of conventional products, enabling high-definition image capture of distant objects such as road signs up to 160m away.

 

Moreover, the sensor is equipped with a pixel binning mode achieving the high level of low lighting sensitivity of 2666 mV. This capability enables the capture of images such as pedestrians or obstacles, even in dark situations. The sensor is equipped with a unique function that captures dark sections at high-sensitivity settings as well as bright sections at high resolution alternatively, enabling high-precision image recognition when combined with post-signal processing.

IMX324 is expected to offer compatibility with the "EyeQ®4" and "EyeQ®5" image processors currently being developed by Mobileye, an Intel Company headquartered in Israel, for use in ADAS and autonomous vehicle technology.

 

The sensor also provides a security feature that protects the output image from being altered in any way, another first for image sensors in the automotive cameras vertical. It is also on track to meet the AEC-Q100 Grade 2 reliability testing standards for automotive electronic components by June 2018. For more details and specs, an IMX324 data brief is available.
