Abstract
Provided is a polarized imaging unit that captures time-series polarized images of an object. A polarization information calculating unit calculates polarization information for each polarized image from the time-series polarized images captured by the polarized imaging unit. An object specifying unit specifies the image region of the object on the basis of, for example, a non-polarized image generated by a non-polarized image generating unit on the basis of the polarized image. A state-change detecting unit detects a state change of the object on the basis of a time series change of the polarization information in the image region of the object specified by the object specifying unit. An output unit outputs the detection result of a state change such that the detection result is associated with the non-polarized image generated by the non-polarized image generating unit, the detection result being obtained by the state-change detecting unit.
