Abstract

　映像データのフレーム数が少ない場合でも、一定品質を保つ映像を視聴者に提供することを課題とする。信号出力装置は、入力された画像データに基づいて映像信号を出力する信号出力部２６と、画像データを記憶する記憶部２４と、記憶部２４に記憶された、ひとまとまりの画像データに含まれるフレームの数が所定数を満たしているかを検出する検出部２３と、ひとまとまりの画像データに含まれるフレームの数が所定数を満たしていない場合、ひとまとまりの画像データに含まれるフレームの数が所定数を満たすように、新たなフレームをひとまとまりの画像データに追加し、新たなフレームが追加された、ひとまとまりの画像データを信号出力部２６に入力するデータ作成部２５と、を備える。
