Abstract
An image storage device includes a facial-expression-correlation estimator configured to estimate a facial expression correlation representing a degree of correlation between a facial expression in a face image and a predetermined reference facial expression, the face image being included in time-varying image data; a facial-expression estimator configured to detect, through estimation based on transition of the facial expression correlation, a situation where the facial expression in the face image and the predetermined reference facial expression are expected to come to have a predetermined correlative relationship within a predetermined period; and an image-storage controller configured to exercise control so that the image data in the predetermined period from the detection is maintained in an image-data storage unit.
