Possible to block out sections of V120 image?

by jimmyjoe » Mon Jun 28, 2010 11:56 am

The V120 has a 4:3 640x480 image sensor. Is it possible in the camera to block out sections of this image, so that it ignores spots outside of a 16:9 image that the camera is looking at?

It is possible for the sensor to be a 16:9 sensor instead of 4:3, like some other cameras cameras can be configured.

thanks

You can use the on-camera windowing control to crop out regions on the imager that you don't want. There is not an explicit 16:9 mode, but it can be configured to operate like that (crop to ~640 x 360).

Use the SetOption() call with the following options :

NP_OPTION_WINDOW_EXTENTS_X
NP_OPTION_WINDOW_EXTENTS_X_END
NP_OPTION_WINDOW_EXTENTS_Y
NP_OPTION_WINDOW_EXTENTS_Y_END
