Multi-frame depth-based multi-camera relighting of images

An electronic device comprising:

• a first image sensor configured to capture a plurality of first images;
• a second image sensor configured to capture a plurality of second images;
• and
• at least one processing device operatively coupled to the first image sensor and the second image sensor, the at least one processing device configured to:
• generate a short single view, a short depth map, a long single view, and a long depth map from the plurality of first images and the plurality of second images;
• generate a multi-frame depth map using the short single view, the short depth map, the long single view, and the long depth map;
• generate a gain map using the multi-frame depth map and lighting conditions, wherein the lighting conditions introduce a relighting effect into the gain map;
• apply the gain map to the short single view and the long single view in order to generate a relit short single view and a relit long single view;
• and
• fuse the relit short single view and the relit long single view in order to generate a relit image.

A non-transitory machine-readable medium containing instructions that when executed cause at least one processor of an electronic device to:

• capture a plurality of first images using a first image sensor and a plurality of second images using a second image sensor;
• generate a short single view, a short depth map, a long single view, and a long depth map from the plurality of first images and the plurality of second images;
• generate a multi-frame depth map using the short single view, the short depth map, the long single view, and the long depth map;
• generate a gain map using the multi-frame depth map and lighting conditions, wherein the lighting conditions introduce a relighting effect into the gain map;
• apply the gain map to the short single view and the long single view in order to generate a relit short single view and a relit long single view;
• and
• fuse the relit short single view and the relit long single view in order to generate a relit image.
