1. A method of performing high dynamic range image capture adaptive to scene object distance using an array camera, the method comprising: capturing initial image data using at least one active camera from a plurality of cameras in the array camera; determining whether to utilize high dynamic range imaging for performing image capture using a processor configured by software; and when high dynamic range imaging is determined to be utilized: generating a depth map based on the initial image data using a processor configured by software; determining whether an object is within a predetermined distance from the array camera by evaluating the depth map using the processor configured by software; defining a first subset and a second subset of active cameras within the plurality of cameras in the array camera using the processor configured by software; when the object is not within the predetermined distance: determining a first exposure setting for the first subset of active cameras and a second exposure setting for the second subset of active cameras using the processor configured by software; configuring the first subset with the first exposure setting and the second subset with the second exposure setting using the processor configured by software; capturing single-frame image data using the first subset and the second subset of active cameras, wherein the single-frame image data includes at least one first single-frame image captured at the first exposure setting and at least one second single-frame image captured at the second exposure setting; and synthesizing a first exposure image based on the at least one first single-frame image and a second exposure image based on the at least one second single-frame image using the processor configured by software; and generating a high dynamic range image from the first exposure image and the second exposure image using the processor configured by software.
