Abstract: An image correction device includes a line segment detection module, a shape specification module and an image correction module. The line segment detection module detects from a captured image obtained by photographing a document a plurality of line segments that correspond to the notation on the surface of the document. The shape specification module specifies shape approximation lines that approximate the surface shape of the document from the plurality of line segments. The image correction module utilizes the shape approximation lines specified by the shape specification module to correct the captured image.

Abstract: The object of the invention is to switch between plural sets of waveform data at desired timing while preventing noise. In response to an instruction for switching from a currently reproduced set of waveform data to another set of waveform data, either a switching position in the other set of waveform data or a switching in the currently reproduced set of waveform data is set as end timing for ending the reproduction of the currently reproduced set, with reference to switching position information of the two sets. If the switching position in the currently reproduced set is present within a 50 msec time range before a switching position in the other set that is present immediately after the switching instruction, the switching position in the currently reproduced set is set as the ending; if not, the switching position in the other set is set as the end timing.

Abstract: A desired character train included in a predefined reference character train, such as lyrics, is set as a target character train, and a user designates a target phoneme train that is indirectly representative of the target character train by use of a limited plurality of kinds of particular phonemes, such as vowels and a particular consonants. A reference phoneme train indirectly representative of the reference character train by use of the particular phonemes is prepared in advance. Based on a comparison between the target phoneme train and the reference phoneme train, a sequence of the particular phonemes in the reference phoneme train that matches the target phoneme train is identified, and a character sequence in the reference character train that corresponds to the identified sequence of the particular phonemes is identified. The thus-identified character sequence estimates the target character train.
