Description
ISPs (Image Signal Processors) have long been a very specialized topic for camera systems. The problem is that nowadays almost all cameras are RAW sensors and do not contain an ISP for cost and power consumption reasons. The Arducam OBISP project is designed to solve this problem. As the name suggests, it has an integrated ISP, which has its own hardware processor and is not dependent on the computing power of the back-end processor. Together with the OBISP camera, users can use better cameras on Arduino, Raspberry Pi and Jetson Nano.
The first two published OBISP cameras are the high-resolution 13 MP AR1335 camera and 2 MP AR0230 HDR camera. You use standard 15-pin RPI/Jetson Nano MIPI camera flex cable for use with Raspberry Pi and Jetson Nano/Xavier NX with Arducam's V4L2 kernel driver framework.
The ArduCAM 2 AR0230 OBISP MIPI cam with M12 lens has an integrated ISP (image signal processor) with a very good highlight contrast HDR performance. This has a dynamic range of up to 96 dB.
The standard Raspberry Pi Zero 22-pin MIPI CSI-2 interface is used.
This module is designed to work on Raspberry Pi and Jetson Nano. However, it can also be ported to other MIPI CSI-2 compatible platforms.
The camera driver depends on the kernel. If an upgrade or downgrade is carried out, this must also be done with the opposite side.
Application areas of the 2MP camera include mobile phones, digital photo cameras, PC and IoT cameras and face recognition systems.
