This paper shows basic concept of an artificial emotion and how to construct the system by computer simulation. At first, we show image code dictionary of mixed emotions which are regarded as emotions in usual life, introduced by R. Plutchik. The emotions considerd here are based on the theories of Plutchik. Image codes of mixed emotions can be expressed by vectors consisting of coefficeints on the four attributes to a normalized rectangular basal coordinate system. Secondary the theory for a subjective observation model to the application of emotion processing system is briefly explained. We introduced the system into personal robot kit and some attractive results obtained by the simulated emotion processing system are shown. Emotional behavior of this robot are determined by some simple if-then rules and subjective observation model theory. For computer simulation, we set that an emotional internal state of this robots depends on aquired images using USB camera. We also define facial expressions that consist of two parts of eyes and mouths, which matched pure emotions. Facial expressions with complex emotions are produced by combination of the basic facial expressions.
