How to change the frame of image_mono topic?

[park-dea]

Hello!

I changed the frame rate of stereo.launch file. (15 -> 30)
So, When I checked, the frame of the image_row topic was changed to 30.
But the frame of the image_mono topic is fixed at 60.

How to change the frame of image_mono topic?

Any help or advice would be appreciated, thanks.
