Abstract

In synthesizing a foreground picture and a background picture in accordance with a key signal, for example, by soft chroma key processing, a preview screen 102 as a picture as a result of processing by the key signal and a key parameter setting screen 101 for setting characteristics of the key signal are displayed.
Characteristics of the key signal are changed on a three-dimensional space by information obtained through the key parameter setting screen 101, and the picture as a result of processing is changed on the preview screen 102. Thus, even when the range of key signal setting is adjusted on the three-dimensional color space, desired processing may be carried out by simple operation.
