- This program is just a wrapper around the its.target module, to allow the
- functions in it to be invoked from the command line.
-
- Usage:
- python config.py - Measure the target exposure, and cache it.
- python config.py EXP - Hard-code (and cache) the target exposure.
-
- The "reboot" or "reboot=<N>" and "camera=<N>" arguments may also be
- provided, just as with all the test scripts. The "target" argument is
- may also be provided but it has no effect on this script since the cached
- exposure value is cleared regardless.
-
- If no exposure value is provided, the camera will be used to measure
- the scene and set a level that will result in the luma (with linear
- tonemap) being at the 0.5 level. This requires camera 3A and capture
- to be functioning.
-
- For bring-up purposes, the exposure value may be manually set to a hard-
- coded value, without the camera having to be able to perform 3A (or even
- capture a shot reliably).
