IMX636 HD Sensor

Sony Semiconductor Solutions and Prophesee collaborated to produce SONY IMX636 (HD), a stacked event based vision sensor developed around 4.86um contrast detection pixels.

This Event-based vision sensors feature high-speed/low-latency response, wide dynamic range operation, focal-plane data compression and low power consumption.

A high level of programmability is guaranteed via a four-wire serial peripheral interface. It allows the user to define region of interest and program various functions.

The vision sensor data output is fully digital and consists of 16-wire parallel data bus with an external clock and data valid flag. This interface can easily be connected to an external parallel to LVDS serializer IC.

Features

  • 1280x720 Pixel CMOS vision sensor

  • 4.86μm x 4.86μm event-based pixel

  • <1/2” optical format

  • Monochrome

  • 16-bit parallel data output

  • 1G event/s (1GEPS) peak output

  • Random Programmable Region of Interest (ROI)

  • Serial Peripheral Interface (SPI)

  • High Dynamic Range (HDR) beyond 120 dB

  • −40°C to +85°C Operational temperature range

  • 50-70mW typical power consumption

  • <100mW peak power consumption

Note

In addition to the IMX636, Sony Semiconductor Solutions (SSS) and Prophesee offer three similar event-based sensors detailed on the SSS Event-based Vision Sensor webpage. For instance, the IMX637 shares the same features as the IMX636, with the difference being its VGA resolution of 640x512.

Currently, Prophesee offers EVKs exclusively with the IMX636 sensor. However, by using specific camera plugins, it is possible to use the EVK4 HD (IMX636) to emulate the behavior of the three other IMX636 variants as explained in the Camera Plugins Installation page.

Note

Prior to the IMX636 sensor, some test samples were produced. Those are referred as Gen4.0 and Gen4.1.
