2. C2 Camera Technical Reference Manual#


2.1. Overview#

The C2 camera is a GMSL (Gigabit Multimedia Serial Link) camera specifically designed for automotive applications. It has a resolution of 5.4 MP at 2880 x 1860 px.

Featuring Sony Semiconductor Solutions’ IMX490 back-side illumination stacked CMOS image sensor SoC, this camera enables HDR imaging over 120dB, LED flicker mitigation (LFM), and motion artifact-free image capturing at a frame rate of up to 30fps. The C2 camera is suitable for a variety of applications, such as object recognition and signal recognition, thanks to its simultaneous high sensitivity and high resolution.

With a variety of lens options available, the C2 camera can be adapted to many applications. The lens undergoes a 6-axis active adjustment during installation, allowing it to achieve optimal sharpness even in harsh temperature environments.

Indie-semiconductor’s GW5300 ISP (Image Signal Processor) built into the C2 camera performs various image processing tasks, including lens distortion correction, to achieve optimal image quality for automotive applications. The C2 camera also supports an external triggering mechanism, which is essential to achieve capture synchronization with other sensor modalities such as LiDAR or RADAR, enabling sensor fusion.

Designed for automotive mass production, the C2 camera is ready-to-use. All key components comply with AEC-Q100 (Grade 2), Q101, and Q200 standards, and are designed to pass automotive-grade reliability tests.

2.7.6. Drive mode#

  • Master mode: The camera operates based on its framerate setting.

  • Trigger mode: See below for the details.

2.7.7. Synchronization#


Please note that the trigger specification differs between the C1 and C2 cameras due to the different specifications of their image sensors. When developing a synchronization system using both C1 and C2 cameras, please take this difference into account. Refer to the the specification of C1 camera for the details.

C2 camera supports trigger-based synchronization. The host (e.g., ECU) sends a synchronization signal (FSYNC) via the GMSL interface to the image sensor. When the image sensor receives an FSYNC signal, the readout starts.


Fig. 2.18 FSYNC adjusts frame output timing#

More precisely, the camera will adjust its start timing of readout by measuring the time difference between the internal synchronization timing and FSYNC reception timing. This adjustment occurs 2 frames after the FSYNC reception.

The exposure will start before the exposure time which is controlled by the camera or user.


Fig. 2.19 Timing adjustment frame#

In trigger mode, in case no FSYNC is inputted to the camera, the camera will output the image data based on its original frame rate setting.

The FSYNC pin of the image sensor is connected to the MFP3 GPIO of the serializer. The user needs to configure the deserializer so the synchronization output pin on the ECU is mapped to this pin.
