Description

本発明は上記の課題を解決するために、階調表現の異なる複数の画像を切り替えて再生する機能を有する画像処理装置であって、階調表現の異なる複数の画像データを第１のフレームレートで再生する第１の再生手段と、グラフィック画像のデータ生成を行うグラフィック生成手段と、前記グラフィック生成手段によって生成された画像データと前記第１の再生手段によって再生された前記複数の画像データを合成して前記第１のフレームレートで出力する合成手段と、前記合成手段によって合成された画像データを、前記第１のフレームレートよりも高い第２のフレームレートで再生する第２の再生手段と、を備える。
In order to solve the above problems, the present invention is an image processing apparatus having a function of switching and reproducing a plurality of images having different gradation representations, and a plurality of pieces of image data having different gradation representations are converted to a first frame rate. synthesis and first reproducing means for reproducing in a graphic generation means for performing data generation of the graphic image, the plurality of image data reproduced by the the generated image data first reproducing means by said graphics generator means synthesizing means for outputting at the first frame rate and a second reproduction means for the image data synthesized by said synthesizing means, for reproducing at a high second frame rate than the first frame rate, Is provided.
