Abstract
An image processing method for calculating feature amounts of a facial part in a face on the basis of a plurality of image data obtained in chronological order, comparing the calculated feature amounts with a threshold value, and recognizing the facial part, includes: calculating face orientations on the basis of image data; storing, in a storage, the feature amounts calculated from the image data, the feature amounts being associated with the face orientations; and recognizing a facial part in different image data of the face other than the plurality of the image data on the basis of a feature amount calculated from the different image data, the feature amounts stored in the storage associated with the face orientation in the different image data, and a threshold.
