MIPI Camera Command Set (MIPI CCS℠) defines a standard set of functionalities for implementing and controlling image sensors. It enables rapid integration of basic camera functionalities in plug-and-play fashion. It also gives developers flexibility to customize their implementations for more advanced camera and imaging systems.
MIPI CCS is offered for use with MIPI Camera Serial Interface 2 (MIPI CSI-2®), which has been widely adopted by developers around the world to reduce the integration requirements and costs of deploying camera and imaging components in mobile devices. MIPI CCS brings added conveniences to MIPI CSI-2, enabling developers to further reduce integration requirements and costs for complex imaging and vision systems.
MIPI CCS enables developers to craft a common software driver to configure the basic functionalities of any off-the-shelf image sensor that is compliant with MIPI CCS and MIPI CSI-2 v2.0 or higher. The MIPI CCS specification provides a complete command set that can be used to integrate basic image sensor features, such as resolution, frame rate and exposure time, as well as advanced features such as phase detection auto focus (PDAF), single frame HDR, or fast bracketing. In addition to image sensors supporting I2C/I3C-based CCI, this specification can also be used with Unified Serial Link (USL) image sensors.
MIPI CCS v1.1, released December 2019, includes support for CCS Static Data to standardize capability and configuration files, and faster PHY support—higher than 2.5 Gbps with MIPI D-PHY and 3.0 Gsym/s with MIPI C-PHY.
As a specification designed for use with MIPI CSI-2 v3.0, MIPI CCS v1.1 is backward compatible with earlier versions of the MIPI CSI-2 interface.
MIPI CCS is implemented on either of two physical layers from MIPI Alliance:MIPI C-PHY℠ orMIPI D-PHY℠.
The full specification is available to MIPI Alliance members on the member website, and a public version is also available for download by nonmembers. To foster product interoperability, conformance test suite (CTS) documents for v1.0 and v1.1 are available to both MIPI members and nonmembers.
