Abstract:
An optical image stabilization (OIS) circuit, applied to an OIS device including a single sensor configured to provide sensor data is provided. The OIS circuit includes a main OIS circuit configured to output a control signal to the sensor, and receive the control signal from the sensor with sensor data, output an interruption signal to initiate a control operation, and control a main OIS operation, and a sub-OIS circuit configured to be synchronized with the main OIS circuit based on the control signal input with the sensor data, and control a sub OIS operation based on the interruption signal.
