Abstract
Abstract A screen control apparatus and a screen control method enabling an operator to instruct a display apparatus both of a type and an amount of processing in an intuitive and an easy way by voice to provide good human interfacing. The screen control apparatus comprises a sound input means for receiving voice instruction on a screen and generating a sound signal, a sound recognition means for recognizing sound signal, a sound continuation detection means for detecting the sound continuation of the sound signal, and a screen processing means for processing said picture on the screen in accordance with the recognized sound signal for a time of the detected sound continuation. The screen control method includes the steps of receiving voice for instructing a processing a picture on a screen and generating a sound signal, extracting a sound feature of the sound signal, discriminating the sound signal in accordance with the extracted sound feature to generate a recognized sound signal, detecting the sound continuation of the sound signal, and processing displayed picture on the screen in accordance with said recognized sound signal by a time of said detected sound continuation.
