Multiple camera autofocus synchronization

An apparatus comprising:

• an image processor;
• and
• a memory storing instructions executable to cause the image processor to perform operations comprising:
• performing a first autofocus operation on a first region of interest in a scene captured by a first camera, the first autofocus operation performed in response to a determination that a dynamic computation of a region of interest shift from a second camera to the first camera is unsuccessful, and the first autofocus operation comprising adjusting a focus of the first camera based on a distance between the first camera and an object within the first region of interest;
• determining a second region of interest in the scene captured by the second camera, the second region of interest determined based on the distance and the first region of interest;
• performing a second autofocus operation on the second region of interest;
• and
• fusing a first image of the scene captured by the first camera with a second image of the scene captured by the second camera to generate a fused image, wherein the first image is based on the first autofocus operation, and wherein the second image is based on the second autofocus operation.

A non-transitory computer-readable medium comprising instructions for performing an image autofocus operation using multiple cameras, the instructions, when executed by an image processor, cause the image processor to perform operations comprising:

• performing a first autofocus operation on a first region of interest in a scene captured by a first camera, the first autofocus operation performed in response to a determination that a dynamic computation of a region of interest shift from a second camera to the first camera is unsuccessful, and the first autofocus operation comprising adjusting a focus of the first camera based on a distance between the first camera and an object within the first region of interest;
• determining a second region of interest in the scene captured by the second camera, the second region of interest determined based on the distance and the first region of interest;
• performing a second autofocus operation on the second region of interest;
• and
• fusing a first image of the scene captured by the first camera with a second image of the scene captured by the second camera to generate a fused image, wherein the first image is based on the first autofocus operation, and wherein the second image is based on the second autofocus operation.

An apparatus comprising:

• means for performing a first autofocus operation on a first region of interest in a scene captured by a first camera, the first autofocus operation performed in response to a determination that a dynamic computation of a region of interest shift from a second camera to the first camera is unsuccessful, and the first autofocus operation comprising adjusting a focus of the first camera based on a distance between the first camera and an object within the first region of interest;
• means for determining a second region of interest in the scene captured by the second camera, the second region of interest determined based on the distance and the first region of interest;
• means for performing a second autofocus operation on the second region of interest;
• and
• means for fusing a first image of the scene captured by the first camera with a second image of the scene captured by the second camera to generate a fused image, wherein the first image is based on the first autofocus operation, and wherein the second image is based on the second autofocus operation.
