Sony reveals highest resolution image sensor for Automotive cameras

Sony recently announced the release of the IMX324, a new 1/1.7-type stacked CMOS image sensor equipped with the industry’s highest resolution 7.42 effective megapixel RCCC filter for forward-sensing cameras in advanced driver-assistance systems (ADAS).

This image 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 of up to 160 meters 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.

Sony is providing another industry-first innovation with the efficient stacked design of the IMX324. The pixel array and signal processing circuit is layered allowing for a compact size and low power consumption while still delivering the industry’s highest resolution.

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 new sensor also leads the industry with a security feature that protects the output image from being altered in any way, a first for image sensors in the automotive cameras vertical. The industry-leading sensor is on track to meet the AEC-Q100 Grade 2 reliability testing standards for automotive electronic components by June 2018. Sony has also introduced ISO-26262 automotive functional safety compliant development process to ensure that design quality satisfying the functional safety requirements for an ASIL B(D) level automotive product.

The sensor’s main Features comprise 7.42 megapixels (the industry’s highest resolution for image sensors for automotive cameras), high sensitivity of 2666 mV (Standard value F5.6, when using pixel binning mode), industry’s first automotive grade stacked image sensor, and assured quality standards and functions required for automotive applications.
