An electrical connection device comprises a socket and a plurality of holders. The position and orientation of the viewpoint are obtained by using the generated virtual space image. The customer memory capacity and the customer memory width are selectively transformed by inverse factors based at least in part on a comparison of the customer memory capacity and the standardized memory capacity. The resonator further includes a dielectric resonator body, having a central portion with a plurality of members extending outwardly from the central portion. The mosaic pattern contained in the optical filter is tailored to provide advantageous chrominance information.
