Sony today officially released the "IMX735", a new generation of top-level CMOS image sensor for automotive cameras. It has an unprecedented 17.42 million pixels and is especially suitable for autonomous driving applications.A key prerequisite for realizing autonomous driving is high-precision detection and identification covering the 360-degree environment around the vehicle. Therefore, there is considerable demand for vehicle-mounted image sensors, which must have strong pixel resolution capabilities and be organically integrated with lidar and other sensing systems.

So Sony IMX735 achieves up to 17.42 million effective pixels, of whichThere are 3017 pixels in the horizontal direction and 5777 pixels in the vertical direction. The sensor size is 1/1.17 inches (diagonal length is about 13.70 mm), and the size of a single pixel is only 2.1x2.1 microns.
Its frame rate is 3AD45FPS, 4AD40FPS (all pixels), and its sensitivity reaches 880mV (green pixels).

In addition to ultra-high pixels and resolution,It also abandons the traditional sensor's longitudinal line-by-line output signal and changes it to horizontal column-by-column output, which can better synchronize with the horizontal scanning mechanical scanning lidar and improve the detection and identification capabilities of the autonomous driving system.
IMX735 also has Sony's self-developed pixel structure and special exposure method, thereby increasing the saturated illumination range.Even when HDR and LED flicker suppression are used at the same time, the dynamic range can reach 106dB, and in dynamic range priority mode, it can even be as high as 130dB.
This helps reduce motion artifacts when shooting moving objects and suppress highlight overexposure under backlight conditions, allowing for more accurate capture of targets, such as in environments with large brightness differences such as tunnel entrances and exits.
In addition, IMX735 will pass the AEC-Q100Grade2 automotive electronic component reliability test before mass production, and has introduced a development process that complies with the ISO26262 road vehicle functional safety standard, reaching the automotive safety integrity level ASIL-B(D), thereby improving product reliability.
Optional support for network security functions, such as public key algorithm camera verification and communication verification, to avoid tampering.
Sony IMX735 plans to ship within this month, and the sample price includes tax of 30,000 yen, which is approximately RMB 1,490.
