(5) Eye Control Response Time
The 32-bit RISC microcomputer improves the processing performance and the
improved Eye Control algorithm increases the processing speed. The EOS ELAN 7 E
/ EOS 30's Eye Control response time is less than half the EOS Elan II E/50 E/55's.
The response time during the calibration procedure is also shorter.
