Abstract
A rotation rate detecting apparatus that includes a rotation rate calculating unit configured to calculate a rotation rate of a pedal in a riding apparatus having the pedal rotating by pedaling operation of a user, based on sensor information of an acceleration sensor. The rotation rate calculating unit calculates a rotation rate based on information corresponding to acceleration in a traveling direction of the riding apparatus or a roll direction with respect to the traveling direction in association with movement of the user or the riding apparatus.
Claims18
A rotation rate detecting apparatus, comprising:
- circuitry configured to:
- acquire sensor information from an acceleration sensor, wherein the sensor information corresponds to fluctuation of an output value of the acceleration sensor;
- calculate, based on the sensor information, a rotation rate of a pedal in a riding apparatus, wherein the pedal is rotatable by a pedaling operation;
- store the calculated rotation rate in a recording medium,
- wherein the stored rotation rate is associated with information of a video generated by an imaging apparatus mounted on one of the riding apparatus or a user of the riding apparatus;
- search the video based on a change point of the stored rotation rate, wherein
- the change point is stored as an index for the search, and
- the change point corresponds to a time of change in a movement state of the riding apparatus;
- and
- control a display screen to concurrently display the video and the calculated rotation rate of the pedal.
