According to this invention, in order to efficiently output images, when an image and its attribute are selected, and an extraction output instruction of an image region with the selected attribute is issued, the selected image is segmented into image regions with different attributes, and an image region with the selected attribute is extracted and displayed from the segmented image regions. The instruction execution pipeline comprises: 1) an instruction fetch stage; 2) a decode stage; 3) an execution stage; and 4) a write-back stage. The second beam has a polarization orthogonal to the polarization of the first beam, and the second beam is substantially parallel to the first beam.
