1. An image capture device, comprising:
a first image sensor;
a second image sensor;
a memory configured to store instructions; and
a processor configured to execute the instructions to:
generate metering maps for panoramic image capture bands of the first image sensor and of the second image sensor;
determine control statistics corresponding to auto exposure levels metered for the first image sensor and the second image sensor based on luminance weights represented within the metering maps; and
produce a spherical panoramic image using portions of first hemispherical image data and second hemispherical image data corresponding to the panoramic image capture bands, wherein the first hemispherical data and the second hemispherical data are detected using the first image sensor and the second image sensor based on the control statistics.
