Abstract
A camera system is configured to capture, via a plurality of cameras, 360 degree image information of a local area, at least a portion of which is in stereo. The camera system determines respective exposure settings for the plurality of cameras. A minimum shutter speed and a maximum shutter speed are determined from the determined exposure settings. A set of test exposure settings is determined using the determined minimum shutter speed and maximum shutter speed. A set of test images is captured using the plurality of cameras at each test exposure setting in the set of test exposure settings. Each set of test images includes images from each of the plurality of cameras that are captured using a same respective test exposure setting. A global exposure setting is selected based on the captured sets of test images. The selected global exposure setting is applied to the plurality of cameras.
