Use procedure 1 (when side by side is set)
Use procedure 2 (when preview has already started)

Remarks

After setting the camera mode in setEpsonCameraMode, be sure to perform
setParameters. Changed content is not reflected in the camera device until
setParameters is executed.

When the preview has already started, use stopPreview to temporarily stop the
preview, and then set the camera mode.

Each camera mode has a limited combination of preview resolutions and frame rates.
Note that a run-time exception will occur in setParameters for combinations that
exceed the limit.

The parameters for associated frame rates and preview resolutions will not change
even if you set the camera mode in setEpsonCameraMode. Application developers
should set these parameters using appropriate combinations before executing
setParameters. Please refer to
Table 6
-
4
for available setting parameters.

Capturing resolution is fixed by each mode. Change setting by using setPictureSize
which is Android standard API is not available.
