Mt9m114 high fps

I recently bought an OPENMV CAM H7 R2 with MT9M114 camera sensor to work on a project where i intent to capture images of moving objects. The board specification says that the maximum FPS is 80 but i was reading the DS for the MT9M114 and it says that it can give up to 120 FPS for a QVGA resolution.

Is it possible to get higher fps with this camera, if so how can i achieved that?

My main issue is that since this camera has rolling shutter instead of global shutter, images of moving objects tend to be deformed, but since fps is also related with how fast the image is capture, if i can improve the fps maybe i can capture the objects fast enough so it does not get any deformation.

I would appreciate any help on this topic!

Hi…

I can get it to do 120 FPS… but the image doesn’t look good:

sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.ioctl(sensor.IOCTL_SET_READOUT_WINDOW, (0, 0, 640, 480))
sensor.set_framesize(sensor.QQVGA)

There’s some issue with the settings on the ISP. Unfortunately, this isn’t documented by OnSemi. So, without them billing us NRE time I don’t know how to make it do what you want. There’s some issue with the ISP onboard falling over when asked to go this fast.
