The Great Gatsby, my eyes picked him out obscurely in the anteroom

Could you please tell me if in this excerpt from The Great Gatsby, chapter 4, "obscurely" means "in the half-light" or "indistinctly"?

Roaring noon. In a well-fanned Forty-second Street cellar I met Gatsby for lunch. Blinking away the brightness of the street outside my eyes picked him out obscurely in the anteroom, talking to another man.

Thank you.
