We also found similarities to the W53H on the camera side of the mainboard, specifically, the 1seg antenna and the CDMA 2000 sub-antenna.

The W53H used a sheet-metal antenna and an on-board pattern antenna, in addition to the tunable antenna, for the 1seg reception. The W61CA possibly used the rod antenna in place of these antennas.

Fomalhaut Techno Solutions, the company that helped us disassemble the handset, estimated that the LSI directly connected to the camera module was EXILIM engine for Mobile. As could be seen from the letters printed on the package, the LSI was likely integrated with an ARM core.
