1. A system comprising:

  • an image sensor including a first plurality of pixels and a second plurality of pixels, wherein a first pixel from the first plurality of pixels is disposed immediately adjacent a second pixel of the second plurality of pixels in a sensing area;

    an optical device configured to control an amount of exposure of the first pixel and the second pixel such that the first pixel has a first exposure and the second pixel has a second exposure, wherein the first exposure and the second exposure are taken simultaneously synchronously, and wherein the first exposure differs from the second exposure; and

    a non-transitory processor-readable storage medium storing processor executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising;

    determine both a first luminance from the first exposure and a second luminance from the second exposure; and

    determine a composite luminance from the first luminance and the second luminance wherein the composite luminance is determined by interpolating between the first luminance and the second luminance and according to a light condition, and wherein the interpolating comprises a bicubic interpolation where the value of the first pixel is based on sixteen pixels surrounding the first pixel.
