= Hi folks,

I'm using a OmniVisi= on OV5640 MIPI-CSI2 image sensor with a iMX6 Quad board, and I'm doing some= computer vision applications. I'm curious to know why the driver for the O= V5640 sensor is limited to 30 fps, even though the sensor can do 60 fps at = 720p and 90 fps at VGA? As far as I can see in the driver, the frame rate i= s clamped to maximum 30 fps.

Is there a technical re= ason, or is it just because it hasn't been updated for all the supported mo= des?

<= span lang=3DEN-US style=3D'font-size:10.0pt;font-family:"Helvetica","sans-s= erif";color:#3D3D3D'>

The driver also limits the available image form= ats, which makes one required to do the conversion in software or (as in my= case) using the IPU. The IPU is fairly fast to do the simple UYVY to RGB24= conversion, but still slower than just getting an RGB image from the senso= r.

Best,

Jacob

Only few configurations are implemented.
