摘要:
A camcorder (100), which is an example of image capturing devices, includes the following units. An imaging unit (110) captures moving pictures. An attribute information generation unit (120) generates attribute information indicating features of the moving pictures captured by the imaging unit (110). An evaluation unit (130) applies the attribute information generated by the attribute information generation unit (120) to a predetermined criterion, so as to calculate an evaluation value of the moving pictures for each predetermined time width. A still picture extraction unit (140) extracts a still picture from moving pictures in a predetermined time width, when the evaluation value calculated by the evaluation unit (130) for the predetermined time width exceeds an evaluation threshold value. A threshold value change unit (150) changes the evaluation threshold value based on at least one of person information and a composition change amount which are included in the attribute information. The person information is used for specifying a person captured in the moving pictures, and the composition change amount is an amount of change in image compositions between the moving pictures.
