Multi-camera device

A method, comprising:

• obtaining first input data from a first camera of a multi-camera device, wherein the first input data is data from a field of view of the first camera;
• obtaining second input data from a second camera of the multi-camera device, wherein the second input data is data from a field of view of the second camera and wherein the second camera is orientated in a different direction to the first camera;
• defining a first region or object of interest for the first camera and a second region or object of interest for the second camera;
• tracking the first region or object of interest while also tracking the second region or object of interest;
• generating a first output data based on the first input data, wherein the first output data is data from a viewport of the first camera, wherein the viewport of the first camera depends on the tracking the first region or object of interest;
• generating a second output data based on the second input data, wherein the second output data is data from a viewport of the second camera, wherein the viewport of the second camera depends on the tracking the second region or object of interest;
• and
• generating a multi-camera output that includes the first and second output data,
• wherein:
• simultaneously, the viewport of the first camera is narrower than the field of view of the first camera and the viewport of the second camera is narrower than the field of view of the second camera;
• and
• tracking the first region or object of interest comprises keeping the first region or object of interest within the first output data and tracking the second region or object of interest comprises keeping the second region or object of interest within the second output data.

A computer program embodied on a non-transitory computer-readable medium, said computer program comprising computer-readable code which, when executed by at least one processor, causing performance of:

• obtaining first input data from a first camera of a multi-camera device, wherein the first input data is data from a field of view of the first camera;
• obtaining second input data from a second camera of the multi-camera device, wherein the second input data is data from a field of view of the second camera and wherein the second camera is orientated in a different direction to the first camera;
• defining a first region or object of interest for the first camera and a second region or object of interest for the second camera;
• tracking the first region or object of interest while also tracking the second region or object of interest;
• generating a first output data based on the first input data, wherein the first output data is data from a viewport of the first camera, wherein the viewport of the first camera depends on the tracking the first region or object of interest;
• generating a second output data based on the second input data, wherein the second output data is data from a viewport of the second camera, wherein the viewport of the second camera depends on the tracking the second region or object of interest;
• and
• generating a multi-camera output that includes the first and second output data,
• wherein:
• simultaneously, the viewport of the first camera is narrower than the field of view of the first camera and the viewport of the second camera is narrower than the field of view of the second camera;
• and
• tracking the first region or object of interest comprises keeping the first region or object of interest within the first output data and tracking the second region or object of interest comprises keeping the second region or object of interest within the second output data.
