background reflections; reflected glare
Refers to unwanted reflections on a surface, such as a window, screen, or glass, that obscure the view.
The reflections on the window make it hard to see the outside scenery.
When taking a photo, please be careful of reflections on the glass.
Compound of 映り (うつり, continuative form of 映る 'to be reflected') and 込み (こみ, continuative form of 込む 'to go into'), literally 'reflection going in'.
