1. A system, comprising:
an image sensor configured to capture image data using a plurality of selectable exposure times; and
a processing apparatus configured to:
receive a first image from the image sensor, wherein the first image is captured with a first exposure time;
receive a second image from the image sensor, wherein the second image is captured with a second exposure time that is less than the first exposure time;
determine a high dynamic range image based on the first image and the second image, wherein determining the high dynamic range image includes using a blending ratio map to specify how an image portion of the second image is combined with a corresponding image portion of the first image to determine a corresponding image portion of the high dynamic range image; and
store, display, or transmit an output image that is based on the high dynamic range image.
