Abstract
A television signal receiver comprises a tuner, a decoder, a first storage medium that stores a frame of video signals extracted by the decoder as a captured image, a second storage medium that stores sound data representing a variety of shutter sounds to be generated for informing a user that a captured image has been stored in the first storage medium, and a sound generating circuit that, when a captured image is stored in the first storage medium, selects a shutter sound among the variety of shutter sounds represented by the sound data stored in the second storage medium and generates the selected shutter sound. Since the television signal receiver is configured to generate a shutter sound when a captured image is stored in the first storage medium, it can inform a user about storage of a captured image in the first storage medium without causing video images of a television program to be partly hidden from view. Further, since the television signal receiver is capable of generating the variety of shutter sounds, it can provide a user with various kinds of information by varying the shutter sound to be generated.
