MIPI CCS Tools

General Info

• Overview

  MIPI CCS Tools is a common toolset for CCS Static Data, the standardized method in MIPI Camera Command Set (MIPI CCS℠) v1.1 for describing a sensor's limits and capabilities outside of hardware. It complements CCS v1.1, further simplifying the integration of image sensors in mobile and mobile-influenced devices.

  CCS Tools was developed for anyone who works with CCS Static Data, including hardware engineers, programmers and testers. The same works across vendors, devices and operating systems.

• Capabilities

  MIPI CCS defines standard functionalities for implementing and controlling image sensors, enabling rapid integration of sensors. CCS Static Data, introduced in CCS v1.1, is a standard format for information about sensors, including model-specific registers (MSRs), that can be parsed by device drivers. One driver can interact with many different image sensors, determining their characteristics by referring to their CCS Static Data files. This allows vendors and system integrators to add support for new image sensors and update MSRs without making driver changes.

  CCS Tools helps developers take advantage of CCS Static Data without writing their own tools or debugging multiple implementations developed by others. This reduces complexity for vendors and system integrators, lowering costs and accelerating time to market for mobile and mobile-influenced devices.

• Using CCS Tools

  CCS Tools has three main elements to help developers implement and update image sensors:

  • A definition of a plain-text format for CCS Static Data files, based on YAML and easily produced by scripts and other programs. Developers can use this format for reading and editing CCS Static Data files.
  • A Perl script to convert those text-based files to the size-optimized CCS Static Data binary format.
  • A reference implementation of a parser library that can be incorporated in device drivers. The library, written in C, parses CCS Static Data binaries generated by the converter and ensures they are read the same way wherever the library is used. This helps make it possible to have one common driver for each OS instead of many device-specific drivers.

• Latest Release

  Anyone can write and contribute MIPI CCS 1.1 drivers for specific operating systems. A common Linux driver for CCS is now being developed for inclusion in the Linux mainline kernel.

  CCS Tools is available to non-members.
