Something that's always bugged me

Theres something that has always bugged me in Balde Runner.<BR>When Deckard is looking at Leons picture in the Esper machine, after Deckard says:<BR>'Enhance. Stop.' and the Esper machine enhances, he leans forward, and we hear the Esper machine do something, but Deckard has given no command. And the next time we see the machine it seems nothing has happned. So my question is, why does it make the sound effect? was Deckard supposed to give a command to it or what?

Perhaps he was searching the photo for a longer time... I always thought ithere was a cut.

ya probably bad editing and sound placement

A lot of the Esper moves do not match what Deckard actually says. So a few extra sounds is not unexpected.
