In an image communication system for compositing and generating an image for enhancing the communication, a composite image generator in a communication terminal analyzes voice data and image data, and an analyzer analyzes voice data to detect an emotion parameter. Basic emotion data are generated by a movement controller, an emotion movement pattern storage and a basic emotion generator, based on the emotion parameter. An expression compositor composites the basic emotion data with expression data, extracted from image data, to generate composite expression data. An image compositor composites the composite expression data with character data to generate a composite character image.
