1. An apparatus comprising: a scaling circuit configured to generate a plurality of scaled frames each having a plurality of pixels with a first exposure in response to a first subset of a plurality of frames generated by a sensor; a luma circuit configured to generate an average luminance value for each of a plurality of pixels having a second exposure in each of a second subset of said plurality of frames generated by said sensor; and a blending circuit configured to generate a plurality of output frames, wherein (A) each of said pixels of said output frames are selected in response to one of said average luminance values and (B) portions of each of said output frames provide a gradual linear blend between said pixels having said first exposure and said pixels having said second exposure.
