An object insertion system is provided for inserting a portion of a model image into an image signal. The object insertion system includes a camera that obtains the model image. An image processor determines the portion of the model image to be inserted into the image signal from the model image obtained by the camera. The image processor extracts the portion of the model image from the model image. An image extractor determines an image component of the image signal, and the image processor inserts the portion of the model image into the image signal as the image component. The image processor determines the portion of the model image from the model image obtained by the camera based on the image component of the image signal determined by the image extractor.
