It seems that HTTrack cannot identify the hyperlinks locateded inside the Flash
web page. 

A solution is to add the wanted urls as links HTTrack should mirror. In other
words, tell HTTrack to mirror all of the following links, not just the first
one:

<http://web.canon.jp/imaging/enjoydslr/index.html> 
<http://web.canon.jp/imaging/enjoydslr/part1/index.html> 
<http://web.canon.jp/imaging/enjoydslr/part2/index.html> 
<http://web.canon.jp/imaging/enjoydslr/part3/index.html> 
<http://web.canon.jp/imaging/enjoydslr/part4/index.html> 
<http://web.canon.jp/imaging/enjoydslr/terminology/index.html>

From the command line I would type this command (I'm using Mac OS X): 
httrack <http://web.canon.jp/imaging/enjoydslr/index.html>
<http://web.canon.jp/imaging/enjoydslr/part1/index.html>
<http://web.canon.jp/imaging/enjoydslr/part2/index.html>
<http://web.canon.jp/imaging/enjoydslr/part3/index.html>
<http://web.canon.jp/imaging/enjoydslr/part4/index.html>
<http://web.canon.jp/imaging/enjoydslr/terminology/index.html> -O
