(57) Techniques for improved focusing of camera arrays are described. In one embodiment,
a system may include a processor circuit, a camera array, and an imaging management
module for execution on the processor circuit to capture an array of images from the
camera array, the array of images comprising first and second images taken with first
and second values of an exposure parameter, respectively, the first value different
than the second value, to estimate a noise level, to normalize an intensity of each
image based upon the noise level of the respective image, to produce a respective
normalized image, to identify candidate disparities in each of the respective normalized
images, to estimate a high dynamic range (HDR) image patch for each candidate disparity,
and to compute an error from the HDR image patch and an objective function, to produce
a disparity estimate. Other embodiments are described and claimed.
