The IMX636 from Sony Semiconductor is a 0.92 Megapixel Event-based Vision Sensor (EVS) that is designed for recognition processing systems. It produces high-speed, low latency data output by detecting luminance changes, which each pixel senses asynchronously, and only outputting the differential data after combining with the coordinate and time information. This image sensor has a 1/2.5 inch optical format based on Sony’s original stacked structure to provide high image resolution, high speed, and high temporal resolution. It can detect up to 1.06 Geps (giga events/sec) with an ROI better than 100 μs and thinned read-out better than 220 μs. This sensor has a dynamic range of over 86 dB and a black & white filter with an event signal processing function to control anti-flicker, event filter & event rate. It can be controlled via I2C or 4-wire SPI interfaces and uses 2 lane MIPI D-PHY(1.5 Gbps/lane) & 4 lane SLVS(800 Mbps/lane) interfaces for output.
The IMX636 requires a DC supply of 3 V (analog), 1.1 V (digital) and 1.8 V (interface). It is available in a ceramic LGA package that measures 13 x 13 mm and is ideal for the detection of fast-moving objects, equipment monitoring, movement detection analysis, and image recognition in industrial sector applications.
