PLATFORM ARCHITECTURE FOR ACCELERATED CAMERA CONTROL ALGORITHMS

摘要

Camera control architecture and methods that distribute control responsibilities across hard real-time and soft real-time parts. The operation of digital camera control algorithms can be made less sensitive to timing fluctuations among the various systems within a device platform that includes a camera module (CM) and/or image signal processing (ISP) pipeline. Real-time dispatch of control parameter values may be offloaded from a controller responsible for generating control parameter values. With relaxed timing requirements, camera control algorithm libraries may be developed independent of lower-level hardware responsible for managing the dispatch of control parameter values to the CM and/or ISP.

1. A platform for image processing with digital camera control algorithms, the platform comprising:
a camera control bus to couple with one or more camera hardware module (CM); a soft real-time (SRT) camera controller including logic circuitry to:
generate camera control parameter values by executing one or more camera control algorithm; and a hard real-time (HRT) camera controller coupled to both the SRT controller and the camera control bus, the HRT controller including logic circuitry to:
receive the control parameter values intermittently from the SRT controller; andoutput the control parameter values to the control bus in synchronization with actions of a CM associated with exposing consecutive image data frames.
