Abstract
A method includes obtaining multiple input images of a scene based on image data captured using multiple imaging sensors. The method also includes generating a gain map identifying relative gains of the imaging sensors. The gain map is generated using the input images and translational and rotational offsets between one or more pairs of the input images. Generating the gain map may include using, for each pair of the input images, a rotation matrix based on a rotation angle between the pair of the input images. The method may further include using the gain map to process additional image data captured using the imaging sensors.
Claims20
A method comprising:
- obtaining multiple input images of a scene based on image data captured using multiple imaging sensors;
- and
- generating a gain map identifying relative gains of the imaging sensors, the gain map generated using the input images and translational and rotational offsets between one or more pairs of the input images.
An apparatus comprising:
- at least one memory configured to store multiple input images of a scene based on image data captured using multiple imaging sensors;
- and
- at least one processor configured to generate a gain map identifying relative gains of the imaging sensors;
- wherein, to generate the gain map, the at least one processor is configured to use the input images and translational and rotational offsets between one or more pairs of the input images.
A non-transitory computer readable medium containing instructions that when executed cause at least one processor to:
- obtain multiple input images of a scene based on image data captured using multiple imaging sensors;
- and
- generate a gain map identifying relative gains of the imaging sensors;
- wherein the instructions that when executed cause the at least one processor to generate the gain map comprise:
- instructions that when executed cause the at least one processor to use the input images and translational and rotational offsets between one or more pairs of the input images.
