1. A method comprising:
obtaining a processed image by an image capture apparatus, wherein obtaining the processed image includes:
obtaining, by a target exposure component of the image capture apparatus, target exposure output data, wherein obtaining the target exposure output data includes obtaining a target exposure value in accordance with target exposure input data;
obtaining, by an aggregate gain component of the image capture apparatus, aggregate gain output data, wherein obtaining the aggregate gain output data includes obtaining a target aggregate gain value in accordance with aggregate gain input data and a remaining gain value, obtained in accordance with the aggregate gain input data and the target exposure value;
obtaining, by an auto-exposure compensation component of the image capture apparatus, auto-exposure compensation output data, wherein obtaining the auto-exposure compensation output data includes obtaining an auto-exposure compensation tone curve in accordance with auto-exposure compensation input data, the target exposure value, and an auto-exposure compensation gain value, obtained in accordance with the auto-exposure compensation input data and the target aggregate gain value;
obtaining, by a contrast control component of the image capture apparatus, contrast control output data, wherein obtaining the contrast control output data includes obtaining:
a contrast control tone curve in accordance with a contrast control constraint, contrast control input data, the auto-exposure compensation gain value, and a defined histogram tuning value; and
a contrast control black point value in accordance with a defined black point target percentage and the contrast control input data;

obtaining, by a tone control driver of the image capture apparatus, tone control driver output data, wherein obtaining the tone control driver output data includes obtaining:
a tone control tone curve in accordance with the auto-exposure compensation tone curve and the contrast control tone curve; and
a tone control black point value in accordance with the contrast control black point value;

accessing a current input image captured by an image sensor of the image capture apparatus; and
processing the current input image in accordance with the tone control tone curve and the tone control black point value to produce the processed image; and

outputting the processed image for presentation to a user.
