Abstract: PURPOSE:To display a character, easy to see, always on a monitoring screen by detecting the luminance level of the part, where the character is inserted into, of a video signal, and constituting the brightness of the character so as to be a constant value to have a prescribed level difference between the detected luminance level. CONSTITUTION:A mean luminance measuring means 10 detects the mean luminance level of the part, where the character is inserted into, of the video signal. A character brightness setting means 11 determines the luminance level of the character signal so as to have the level difference larger than the prescribed value against the mean luminance level of the detected video signal, that is, if the luminance level is low, i.e., a dark video image, so as to make the character to be bright, and if the luminance level is high, i.e., a bright video image, so as to make the character to be dark. The character signal luminance level control means (the character brightness setting means) 11 inputs the character signal of the determined luminance level to a video image addition circuit 3. As the result, because the character, displayed on the screen, has the luminance level difference larger than the prescribed level, it is displayed being a distinct character.

It is decided whether or not sound generation is possible over the main channel according to ON information and when the sound generation is possible, a main channel control means 5 generates a period component over the sound generation channel of the main channel and decides whether or not sound generation is possible over the subordinate channel corresponding to the musical sound information. When the sound generation is impossible, OFF processing is performed according to the order of sound generation stored in the assignment memory 3 to generate a sound with the waveform of a non-period component. Consequently, synthesized sounds are obtained most effectively by the determined maximum number of simultaneously generated sounds.
