Abstract
We studied the audio memory technique of recording audio signals directly into image signals. For reason of the human visual property, audio signals are recorded into blue and red signals of picture elements. Audio signals are converted into digital signals of 8 bits which are divided into three blocks of 2 bits and two blocks of a single bit. The former was recorded into a blue signal of three picture elements, the latter into a red signal of two picture elements.
This method made it possible to record audio signals into image signals for about 10 seconds.
