“out of the picture”别理解成“在图片之外”，可以引申为不涉其中；在局外；未参与。

【例句】
Sometimes security was so tight that people who might have had something important to offer were left out of the picture.
有时安全措施过于严密，使本来可能会提供重要情况的人成了局外人。

I can't ask her out until her disapproving brother is out of the picture, so let me know when he leaves the party.
我直到她反对的哥哥不参与才能约她出去，所以当他离开派对的时候请告诉我。
