Systems and Methods for Automatic Exposure of Images

A method comprising:

• causing an image capture device to capture a first image in accordance with first exposure parameters, wherein the first image comprises a plurality of pixels, and wherein each pixel comprises a plurality of channels;
• determining average pixel intensities for each of the plurality of channels;
• determining a weighted average of pixel intensities using the average pixel intensities;
• setting a gain based on the weighted average of pixel intensities;
• setting second exposure parameters for a second image based on the gain;
• and
• causing the image capture device to capture the second image in accordance with the second exposure parameters.

A non-transitory computer readable medium having instructions stored thereon, that when executed by one or more processors cause performance of functions comprising:

• causing an image capture device to capture a first image in accordance with first exposure parameters, wherein the first image comprises a plurality of pixels, and wherein each pixel comprises a plurality of channels;
• determining average pixel intensities for each of the plurality of channels;
• determining a weighted average of pixel intensities using the average pixel intensities;
• setting a gain based on the weighted average of pixel intensities;
• setting second exposure parameters for a second image based on the gain;
• and
• causing the image capture device to capture the second image in accordance with the second exposure parameters.
