As it is not just automatic exposure adjustment but .. (can not find - I already wrote that somewhere) I suggest making some interpreter of the automatic brightness adjustment scripts - with many adjsutable parameters and image conditions/goals it is probably not possible to have a one-size-fits-all adjustment algorithm. What syntax to use so it will be intuitive, and easy to interpret? --Andrey.filippov 00:34, 24 November 2005 (CST)
OK - this can probably be solved in the following way:
- at each given moment only on of the parameters will be adjusted - exposure, gains, "curves" (digital gain) or (later) iris
- some flexibility to define goal function and hysteresis ("don't care" region)
- range parameter is allowed to change before failure is reported
- results are provided to the client javascript that controls the overall process
