摘要： A system for using actuators to control an image sensor and/or lens based on sensor data received from position sensors and position information for the image sensor and/or lens received from a host processor includes a primary camera controller device, at least one secondary camera controller device, and at least one communication link connecting the primary camera controller device and the secondary camera controller device. The primary camera controller device processes the received sensor data and the received position information to generate control data, sends a secondary portion of the control data to the secondary camera controller device via the communication link, and drives a primary portion of the control data to the actuators. The secondary camera controller device drives the received secondary portion of the control data to the actuators concurrently with the primary camera controller device driving the primary portion of the control data to the actuators. A system for using actuators to control an image sensor and/or lens based on sensor data received from position sensors and based on position information for the image sensor and/or lens received from a host processor includes a primary camera controller device, at least one secondary camera controller device, and at least one communication link connecting the primary camera controller device and the at least one secondary camera controller device. The primary and secondary camera controller devices receive respective primary and secondary sensor data from the position sensors, send the respective primary and secondary sensor data to the other camera controller device via the communication link, process the primary and secondary sensor data and the position information to generate respective primary and secondary control data, and drive the respective primary and secondary control data to the actuators concurrently.
