Claim 19:
20. A method comprising:
obtaining, by an image signal processor of an image capture apparatus, a first exposure duration value and a first sensor gain value;
accessing, by the image signal processor, a first input frame of a video captured by an image sensor of the image capture apparatus in accordance with a defined frame rate, an adaptive acquisition control sample rate that is one third of the defined frame rate, the first exposure duration value, and the first sensor gain value;
obtaining, by the image signal processor, a first processed frame for the video corresponding to the first input frame, wherein obtaining the first processed frame includes obtaining a second exposure duration value and second sensor gain value;
accessing, by the image signal processor, a second input frame of the video captured by the image sensor of the image capture apparatus in accordance with the defined frame rate, the second exposure duration value, and the second sensor gain value;
obtaining, by the image signal processor, a second processed frame for the video corresponding to the second input frame, wherein obtaining the second processed frame includes:
obtaining, by an exposure control component of the image signal processor, a third exposure duration value and third sensor gain value;
obtaining, by a tone control component of the image signal processor, a tone control tone curve and a tone control black point value; and
processing, by another component of the image signal processor, the second input frame in accordance with the tone control tone curve and the tone control black point value to produce a processed image; and

outputting the video including the first processed frame and the second processed frame.
