PROBLEM TO BE SOLVED: To provide an image-capturing device with which it is possible to easily measure the motion accuracy or shape accuracy of an object that moves cyclically.SOLUTION: An image-capturing device 1 comprises an image-capturing unit for capturing on a prescribed cycle the image of at least a portion of an object that moves cyclically, and an analysis unit for comparing a plurality of images captured by the image-capturing unit and determining whether at least a portion of the object in the plurality of images is different or not. When the analysis unit determines that at least a portion of the object in the plurality of images is different, the image-capturing unit changes an image-capturing cycle so that different portions of the object in the plurality of images match, and the analysis unit measures the amount of deviation in the motion of the object on the basis of the changed cycle, or the analysis unit measures the amount of deviation in the motion of the object or the amount of deviation in the shape of the object on the basis of the amount of deviation in different portions of the object in the plurality of images.SELECTED DRAWING: Figure 1 |
