Abstract
An apparatus comprising a scaling circuit, a luma circuit and a blending circuit. The scaling circuit may generate a plurality of scaled frames in response to a first plurality of frames generated by a sensor. The first plurality of frames may have a first exposure. The luma circuit may generate an average luminance value for each of a plurality of processed pixels in each of a second of the plurality of frames generated by the sensor. The second of the plurality of frames may have a second exposure and each of the average luminance values is calculated based on a plurality of neighboring pixels in a neighborhood of the processed pixel.
