Abstract: A portable information terminal inserted in an entertainment apparatus operates as if it had a life therein and functions as company that the user can talk to. The portable information terminal comprises a display unit and a casing surrounding said display unit. The display unit and said casing representing a form comprising a head and a body. The display unit functions to present facial expressions of the form. The display unit has a display screen for displaying an image based on image data generated by an image processor. The image processor has a facial expression display controller for reading facial expression information selected by a facial expression selector from a plurality of items of facial expression information, and displaying a moving image representing a deformation from a present facial expression to a facial expression based on the read facial expression information according to a morphing technique.

Abstract: The game sounds were classified into those emitted from left and right speaker units of a television receiver and those emitted from a head set worn by a player, and emission of the individual game sounds from the speaker units or a sound emissive portion of the head set is controlled corresponding to game screens or scenes. This allows the player to enjoy the video game while hearing footstep or whispering of the leading character closely from the head set, and hearing explosive sound or shout of the enemy characters distantly from the speaker units.

Abstract: On the occasion that predetermined voices are recognized, parameters regarding objects are changed appropriately depending on the voice thus recognized, and the objects is displayed on the basis of the changed parameters. For that reason, it is possible to control to display smoothly a battle scene while fastening smoothly an attack and protection and so forth between the character of the leading character and the character of the enemy.

Abstract: An expansion processor has a buffer defining unit for defining one of two buffers as a present inverse quantization buffer and defining one of two buffers as a present restoration buffer, an inverse quantization processor for inversely quantizing a quantized value read for each sample from a DCT data buffer, an IDCT processor for effecting an IDCT process on the inversely quantized data to restore time-domain audio data from frequency-domain data, a low-pass filter processor for removing a high-frequency component from the restored audio data, and an audio data output unit for outputting successive restored samples of audio data to a DAC to output sound from a speaker.

Abstract: A game object is displayed based on a parameter correlated to an object, and upon recognition of a predetermined voice, the parameter is properly altered in response to the recognized voice. This allows control of an object using voice as well as using an operating means such as a controller, to thereby enhance pleasure of operating the object.
