Patent Images
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.

Abstract
Systems, apparatuses, and methods are presented for taking a combination of images taken synchronous in time with one another. According to one example, the present disclosure proposes one or more sensor arrays, each of which comprises multiple pixel sensors arranged to capture image data responsive to light exposure. Light is incident on the respective sensor arrays during substantially synchronous exposures. The one or more sensor arrays are configured such that the image data captured by the respective sensor arrays during the synchronous exposure differ in at least one of a luminance output or a color profile from one another.
