摘要： A moving image acquiring part acquires a moving image. A still image accumulating part stores still images. An image processing part calculates gains obtained by previously storing based on the costs of extraction of still images from a moving image, and extracts some still images with higher gains from among the still images composing the moving image and stores into the still image accumulating part. A request processing part retrieves a still image requested by a request source from the still image accumulating part and transmits to the request source and, when the still image requested by the request source is not stored in the still image accumulating part, extracts the still image requested by the request source from the moving image acquired by the moving image acquiring part and transmits to the request source.

摘要： The data processing device includes a display unit, a touch panel unit that detects a touch operation and outputs detection information, a flick detection unit, a label determination unit, and a teacher data generation unit. The flick detection unit detects a flick direction from the detection information of the touch panel unit. The label determination unit determines a label representing a category to which content belongs, based on the flick direction. The teacher data generation unit displays the content on the display unit, and generates teacher data including the displayed content and the label determined by the label determination unit.
