MIPI Alliance Camera Working Group Overview

Jim Rippie from IEEE-ISTO provides an overview of the MIPI Alliance Camera Working Group. He is the chair of this WG.

The Camera Working Group was formed by the MIPI® Board of Directors to enable industry convergence onto a robust, scalable, power efficient serial interface for imaging peripherals and host processors. As MIPI gathered initial early momentum in 2004, CWG group initially forwarded the legacy MIPI Camera Serial Interface 1.0 specification for approval and began efforts on the next generation.

During 2004-2005, strong participation from a diverse set of member companies produced a major revision to CSI the "Camera Serial Interface 2 v1.0" specification.

CSI-2 specifies the details of protocol transmission over the D-PHY physical layer, a separate specification from the MIPI PHY Working Group. Its scope covers the transmission of serial data from a peripheral to a host processor, including packet formatting, data formats, and error detection and correction. CSI-2 v1 did not address detailed command and control issues, since they vary widely across implementations from different manufacturers and in different OEM software.

Currently, the Camera Working Group focuses on a next generation serial interface, which will expand CSI-2's scope to include some aspects of command and control, moving high bandwidth transmissions across the PHY Working Group's upcoming M-PHY physical layer using the UniPro Working Group's UniPro application layer.
