Subject: Re: [Astro_IIDC] Astro & DMK ROI?

Hi Alberto;

The TIS FireWire IIDC cameras do not support Hardware ROI. They only support fixed sizes (Format 0, 1 or 2) which do not have ROI capability. Only cameras that support Format 7 may be capable of doing ROI.

TIS FireWire cameras only support a cropped software ROI. So you get no improvement in through put at all and are using up the same amount of bandwidth, same frame rate etc.

I could probably  implement it, but it would be only setting a cropping rectangle in the preview. window Then frame grabs and recorded movies would be "cropped" in software and written to disk. The only thing it does is reduce the amount of disk space used for frames and movies. It would be much the same as how the Format 7 code operates now, you pick a width, height and the left / top corner where to set the cropping too.

HTH..

Hello to all,

since i noticed some topics related to possible AIIDC features I ask for a question too.

Yesterday a guy told me that the TIS Winzoz software allows the ROI with the DMK cameras.

Until today i assumed that ROI is impossible to do with DMK cameras so i never wondered about it.

That guy made me very curious ...

Of course this question is addressed to the only one man that can answer... guess who.

Cheers!
