Page Layout ⇒ Adjustments for Frame Title Area in Presentation

[hbaromega]

I want to adjust the area around the text in the frame title in beamer presentation. The text is appearing at the bottom of the frame title area. I want it to be at the center of the vertical space. Also I do not want to compromise with the font size.

Is it possible to change the area of frame title without changing the font size?

I am using a modified "Berkeley" theme. But I hope that my question is general.

Thanks.
