# libcamera lacks some feature support now.
# libcamera lacks some feature support now.
There are two ways to use Legacy mode.
# Use the Legacy version of piOS.
# For the bullseye or newer version of piOS, turn on the Legacy Camera option in raspi-config.
Since the two modes cannot co-exist, Legacy mode needs to be turned off when using V4L2 mode.
==== libcamera and V4L2 mode ====
Now piOS has switched to libcamera-stack mode.
Libcamera is essentially centered on implementing isp functionality, something that is not needed for the MV series cameras. Therefore, we have adopted the V4L2 mode instead of using libcamera-stack.
As with libcamera-stack, our V4L2 model implements the standard V4L2 driver for the linux driver layer too. Based on this driver, the application layer can directly develop programs to acquire images and perform further processing.
===V4L2 mode manual===
We have saved the code for v4l2 mode in this [https://github.com/veyeimaging/raspberrypi_v4l2 github repository].
