I'm guessing here, based upon what seems logical to me. I'm sure Austin knows a lot more about this stuff than I.
Here's my best guess: I assume the sensor element responds as a unique unit, at the moment it gathers the light information, so I also assume it responds in some manner by generating a voltage level based upon the total amount of photons falling on it's overall surface area. I believe CCDs also have an overflow device to "drain" off excessive light exposure, so it doesn't jump or discharge to other adjacent sensor elements. I don't know what type of "curves" the sensors have, in terms of if they are relatively linear or not, but it would seem to make sense (at least to me) to have the CCD respond to all the photons hitting the sensor surface area (until overload), which might be "total sum of" rather than an average, however, I would think that would have the same basic result.
