Abstract
Techniques and examples pertaining to frame synchronization for dynamic frame rate in dual-camera applications are described. A change in brightness in ambient lighting may be detected when an electronic apparatus operates in a dual-camera mode utilizing images captured by a first image sensor and a second image sensor. In response to the detected change in brightness in the ambient lighting, frame rates of the first image sensor and the second image sensor may be synchronized.
Claims20
A method, comprising:
- detecting a change in brightness in ambient lighting when an electronic apparatus operates in a dual-camera mode utilizing images captured by a first image sensor and a second image sensor;
- and
- synchronizing frame rates of the first image sensor and the second image sensor responsive to the detecting.
A method, comprising:
- launching a dual-camera application that utilizes images captured by a first image sensor and a second image sensor;
- detecting a change in brightness in ambient lighting;
- and
- synchronizing a first frame rate of the first image sensor and a second frame rate of the second image sensor responsive to the detecting.

An apparatus, comprising:
- a processor coupled to receive first data representative of first images captured by a first image sensor and second data representative of second images captured by a second image sensor, the processor configured to control a first frame rate of the first image sensor and a second frame rate of the second image sensor by performing operations comprising:
- detecting a change in brightness in ambient lighting based at least in part on the first data or the second data;
- adjusting an exposure time, associated with the first image sensor and the second image sensor, from a first exposure time to a second exposure time responsive to the detecting;
- and
- synchronizing the first frame rate and the second frame rate responsive to the detecting.
