Rev.C OV5647 Camera for Raspberry Pi Improves the Optical Performance

Published by Lee Jackson on

Introduction

In order to meet the increasing need for Raspberry Pi compatible camera modules. The ArduCAM team now released a revision C add-on camera module for Raspberry Pi which is fully compatible with the official one. It optimizes the optical performance than the previous Pi cameras, and give the user a much clear and sharp image. Also, it provides the FREX and STROBE signals which can be used for multi-camera synchronize capture with proper camera driver firmware.

It attaches to Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing with cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data. The camera is supported in the latest version of Raspbian, Raspberry Pi’s preferred operating system

The board itself is tiny, at around 36mm x 36mm. The highlight of our module is that the Lens is replaceable compared to the official one, making it perfect for mobile or other applications where size and image quality are important. It connects to Raspberry Pi by way of a short ribbon cable. The camera is connected to the BCM2835/BCM2836 processor on the Pi via the CSI bus, a higher bandwidth link that carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi.

The sensor itself has a native resolution of 5 megapixels, and has a fixed focus lens onboard. In terms of still images, the camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30, 720p60 and 640x480p60/90 video.

I am interested in the LS-6018. I would like to use it with Canon EOS lenses (EF and EFS mount) using a CS to EF adapter. I would also like to know if the Strobe signal can be used to trigger a flash.

How much does it weigh?

Do you have any documentation on how to use the Strobe and Frex functions?
