1. An image capture device comprising:

  • a first image sensor;

    a second image sensor; and

    an image processor configured to;

    receive image data including a first image from the first image sensor and a second image from the second image sensor, the first image and the second image depicting at least a portion of an image scene and exhibiting local intensity variation relative to one another,partition the first image into a plurality of first blocks of pixels,partition the second image into a plurality of second blocks of pixels,determine a pair of corresponding blocks, the pair of corresponding blocks including an identified first block of the plurality of first blocks and an identified second block of the plurality of second blocks, andgenerate equalized local intensity values for pixels included in the identified first block of the first image and the identified second block of the second image, including mapping intensity values of pixels in the first block to intensity values of pixels in the second-block such that a histogram of the intensity values of pixels of the first block are transformed to more closely resemble a histogram of the intensity values of the pixels of the second block.
