• This shooting is an image that was taken with a distance of 10 meters between object and camera.
• Image range of monitor (width, height and angle) is 10 % less than that of actual data.
• Due to distortion that occurs with a wide-angle lens, actual angle of taken image will be wider
than calculated value.
