将更多内容放在 \title 和 \author 附近，等等

Question

我怎样才能使标题行更靠近作者行和标题图像？

我不使用任何主题。我有这个：

\documentclass{beamer}

\useoutertheme[left,height=0pt,width=0.12\paperwidth]{sidebar}
\setbeamertemplate{sidebar canvas left}[vertical shading][top=black,bottom=white] 

\usefonttheme{structurebold}
\setbeamerfont{title}{size=\huge,series=\bfseries,parent=structure}
\setbeamerfont{author}{size=\large,series=\bfseries,parent=structure}

\title[THE BIG TITLE]{THE BIG TITLE}
\author[]{Me}
\titlegraphic{\includegraphics[scale=0.4]{IMAGE}}
\date{}

\begin{document}

\begin{frame}
%\titlepage % Print the title page as the first slide
\end{frame}

\end{document}
