Patent ID: 8744244

Claim:
A reproducing apparatus which reproduces a sound based on accumulated audio data or audio data sequentially input from outside and outputs the sound from an audio output unit, comprising: an audio data storage unit to store audio data; an analyzing unit to analyze the audio data stored in the audio data storage unit in accordance with a predetermined analysis condition; an imaging unit to convert an analysis result obtained by the analyzing unit into previously set image data corresponding to the analysis result; a generating unit to generate an audio image arrangement diagram in which an audio image based on the image data imaged by the imaging unit is arranged to correspond to a relative time axis originating on a current time point; a video data storage unit to store video data in relation to the audio data; a synthesizing unit to synthesize the audio image arrangement diagram generated by the generating unit and a video reproduced at the current time point based on the video data stored in the video data storage unit, so as to generate a synthesized image; and a display control unit to display the synthesized image generated by the synthesizing unit on a display unit while a sound based on the audio data is reproduced and output from the audio output unit, wherein: in the audio image arrangement diagram, an audio image corresponding to a sound output from the audio output unit at the current time point can be recognized, and the audio image arrangement diagram includes an audio image of any one of three time zones which are a first time zone ranging from the current time point to a past including the current time point, a second time zone ranging from the current time point to a future including the current time point, and a third time zone ranging from a past to a future including the current time point; a duration of the first time zone is equal to a duration of the second time zone; and the audio image arrangement diagram shows at least one of intensity, tone color or fundamental frequency of the audio data.
