In an output control device which controls an amplification factor of an amplifier in response to an input signal and a fade control signal to carry out a fade operation of an output signal, such as a fade-in or a fade-out operation, a level control signal is produced to widely control output levels of the output signal. A plurality of timing signals are produced from either the fade control signal or the level control signal and are selected in response to the level control signal and are selected in response to the level control signal to determine a combination of the timing signals. The amplification factor is controlled by the combination of the timing signals to change the output levels over a wide range by varying the combination of the timing signals from one to another.
A method for gradually adjusting intensity of a color component of pixels of successive images in a video data includes the steps of: a) providing an offset value; b) adding the offset value to the color component of each of the pixels of the successive images of the video data to generate an adjusted color component; c) setting a frequency factor indicative of times of adjustment of the offset value, the frequency factor corresponding to a number of the successive images per adjustment of the offset value; and d) adjusting the offset value in a predetermined manner in accordance with the frequency factor. An apparatus for gradually adjusting intensity of the color component is also disclosed.
An apparatus for continuously reproducing plural sound data has a start end/terminal end determination unit for determining the start end/terminal end of the continued respective sound data, a fade-in/fade-out unit for carrying out fade-in process at the start end of plural respective sound data and/or fade-out process at the terminal end of the same, a data output unit for continuously outputting the plural sound data which have been subjected to fade-in process and/or fade-out process, and a reproduction unit for reproducing the outputted plural sound data. In reproducing continuously the plural sound data, no noise is generated at the joint portion of the adjacent sound data.
