IMX636-AAMR-C Event-Based Vision Sensor with 0.92 M Effective Pixels for High-Speed Low-Latency Output and Logarithmic Output Voltage

The IMX636-AAMR-C is a diagonal 7.1 mm (Type 1/2.5) approx. 0.92 M effective pixels (1280 (H) × 720 (V)) event-based vision sensor. This sensor detects brightness changes that exceed the set thresholds independently for each pixel, and asynchronously outputs the coordinates (X, Y) of detected pixels, the detected times (timestamp), and the brightness change polarity information in the order detected. This enables high-speed, low-latency (100 µs or less at 1000 lx) output. Output of only brightness changes enables to swiftly capture moving subjects, and areas without brightness changes are not output, realizing a sensor that enables efficient data extraction. The sensor also features pixel characteristics where the output voltage is output logarithmically relative to the input light intensity, which enables event output with a high dynamic range. This chip operates with analog 3.0 V, digital 1.1 V, and 1.8 V triple power supply.
