PROBLEM TO BE SOLVED: To realize a high-quality composite picture in simple configuration in compositing a foreground picture and a background picture in accordance with a key signal. SOLUTION: In compositing a foreground picture and a background picture in accordance with a key signal, for example, by soft chroma key processing, a preview picture 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 101. 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. COPYRIGHT: (C)2007,JPO&INPIT |
