Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
A device for correcting a timing of music playing information for use in an auto play device, comprising: music playing information memorizing means for memorizing a timing of a change of a performance of a piece of music; long time data memorizing means for memorizing a long time data, the timing of the change of the performance of a piece of music being corrected to an exact timing occurring at each interval of said long time data; short time data memorizing means for memorizing a short time data, a time length of said short time data being shorter than a time length of said long time data, said short time data being set around a timing occuring at each interval of said long time data; determining means for determining whether or not the timing of the change of the performance of a piece of music is within a range of said short time data; and correcting means for correcting the timing of the change of the performance of a piece of music, which is outside the range of said short time data, to a timing within the range of said short time data, in response to a determination by said determining means.
Claim 2
Independent Claim
202 words
A device for correcting a timing of music playing information for use in an auto play device, comprising: music playing information memorizing means for memorizing a timing of a change of a performance of a piece of music; long time data memorizing means for memorizing a long time data, the timing of the change of the performance of a piece of music being corrected to an exact timing occurring at each interval of said long time data; short time data memorizing means for memorizing a short time data, a time length of said short time data being shorter than a time length of said long time data, said short time data being set around a timing occuring at each interval of said long time data; determining means for determining whether or not the timing of the change of the performance of a piece of music is within a range of said short time data; and correcting means for correcting the timing of the change of the performance of a piece of music, which is outside the range of said short time data, to a timing within the range of said short time data, in response to a determination by said determining means.
