Abstract:
Image signal processing may include flare reduction, which may include obtaining a first input frame captured by a first image capture device of an image capture apparatus, the first image capture device having a first field-of-view, and the first input frame including lens flare corresponding to a primary light source; obtaining a second input frame captured by a second image capture device of the image capture apparatus, the second image capture device having a second field-of-view partially overlapping the first field-of-view; obtaining primary light source information corresponding to the primary light source based on the first input frame and the second input frame; obtaining a processed frame by modifying the first input frame based on the primary light source information to minimize the lens flare; and outputting the processed frame.

Claim (Index 12):
A method comprising:\n obtaining a first input frame captured by a first image capture device of an image capture apparatus, the first image capture device having a first field-of-view, and the first input frame including lens flare corresponding to a primary light source, wherein the first input frame includes a first image circle area based on the first field-of-view; obtaining a second input frame captured by a second image capture device of the image capture apparatus, the second image capture device having a second field-of-view partially overlapping the first field-of-view, wherein the second input frame includes a second image circle area based on the second field-of-view; obtaining primary light source information corresponding to the primary light source based on the first input frame and the second input frame; obtaining a dark corner profile based on a relative illumination of an area outside the first image circle and the second image circle; obtaining an intensity difference between the primary light source information and the dark corner profile; obtaining a flare model; obtaining a flare mask based on a flare difference estimation along a stitch line between the first input frame and the second input frame; obtaining a processed frame by modifying the first input frame based on the primary light source information to minimize the lens flare, wherein modifying the first input frame includes applying the flare model to the first input frame based on the primary light source information and subtracting the flare mask; and outputting the processed frame.
