The valid Macro pixel horizontal size is between 3[SPAD pixel] and 21[SPAD pixel] (columns).
The valid Macro pixel vertical size is between 3[SPAD pixel] and 6[SPAD pixel] (rows).
1.IMX479 Description
The IMX479 is a diagonal 15.8 mm (Type 1/1") diagonal Single Photon Avalanche Diode (SPAD) ToF Depth Sensor with signal-amplifyingpixels. This chip features line-scanning mode. By arraying a large number of SPADs and summing their outputs, the sensor achieves ameasurement distance ofup to 300 m. It is a high-precision distance sensor that measures with 5 cm range resolution from short-range to longrange distances, thereby contributing to improved LiDAR detection and recognition performance. The sensor light emission timing controlfunction is able to compensate for the delay in timing between laser emission and reception. The sensor ambient light reduction functionensures that it does not saturate even under sunlight and can achieve distance measurements with a high dynamic range. Equipped with echoand peak detection functions, ranging data output modes, digital signal processing, and more, the sensor is optimized to meet the performanceand functionality required by LiDARs.
