Epson Moverio Pro BT-2000 Developer's Manual page 88

Use procedure 1 (Set the camera mode to single-through-5m and the preview resolution
to VGA)
In this example, the width and height of the image are reduced to approximately 1/4 and
displayed in a preview.
/*Start camera*/
camera = Camera.open();
/*Acquire current parameter (or default value)*/
Camera.Parameters params = camera.getParameters();
/*Set camera mode to single-through-5m*/
params.setEpsonCameraMode(Camera.Parameters.EPSON_CAMERA_MODE_SINGLE_THROU
GH_5M);
/*Set preview resolution to VGA*/
params.setPreviewSize(640, 480);
/*Set frame rate to 7.5fps*/
params.setPreviewFpsRange(7500, 7500);
/*Reflect camera setting in camera device*/
camera.setParameters(params);
/*Start preview*/
camera.startPreview();
Use procedure 2 (when preview has already started)
/*Stop preview*/
camera.stopPreview();
/*Acquire current parameter (or default value)*/
Camera.Parameters params = camera.getParameters();
/*From here on, use procedure 1*/
Remarks

After setting the preview resolution in setPreviewSize,

setParameters. Changed content is not reflected until setParameters is executed.
When the preview has already started, use stopPreview to temporarily stop the

preview.
Each preview resolution has a limited combination of frame rates and camera

modes. Note that a run-time exception will occur in setParameters for
combinations that exceed the limit.
You cannot set single-through-5m or side-by-side as the preview resolution. If

you want to acquire images in single-through-5M or side-by-side, perform
shooting by using takePicture.
The resolution set for preview resolution uses image data acquired in

PreviewCallback.
