On starting sc tonight my sensor analysis has hone so no smart histogram

Hi,

SharpCap picks the sensor analysis file based on a combination of

* Camera Brand/Name
* The setting in the 'Colour Space' control
* The setting in the 'Read Mode' control if you have one

Any change of those from the configuration in which you did the analysis means that the data cannot be used, so Smart histogram will not show until you also do the analysis in that new configuration.

So, for instance, if you have both 'RAW16' and 'RAW 16 Ultra Low Noise' in the colour space control, you would need to do a separate sensor analysis for each, otherwise if you have only analysed RAW16 and then use 'RAW 16 Ultra Low Noise' you will not see the smart histogram.

Similarly, if your camera can be accessed both via direct SDK access and via an ASCOM driver, sensor analysis done with the camera open via direct SDK access will not give smart histogram under ASCOM (and vice versa)

thanks,

Robin

Hi,

any chance that the camera name has changed slightly for some reason? I've seen this happen before due to driver updates, camera firmware updates or even sometimes when the manufacturer camera SDK is updated. If the name is slightly different then SharpCap will no longer recognise the old data files as belonging to the name of the camera.

You can also check the files - they are stored on disk in the folder

Code: Select all

C:\Users\<your windows login user name>\AppData\Roaming\SharpCap\SensorCharacteristics

The file names are basically in the following form

<Camera Name>~<Colour Space>

or

<Camera Name>~<Colour Space>~<Read Mode>

By looking at the files that exist in that folder, you can see what settings you have measured the camera data for and spot if anything has changed.

cheers,
