An information processing device identifies a search query of a target user to whom an electronic coupon is to be issued and the corresponding search time, and adds the elapsed time between the search time and the current time to an expected interval between the current time and viewing by the target user, to calculate an expected viewing duration. The information processing device then identifies, as estimated viewed items, items associated with an estimated viewing duration of less than or equal to or of less than the calculated expected viewing duration, among items included in estimated viewing duration information corresponding to the identified search query. Based on items included in the target user's history information and on the identified estimated viewed items, the information processing device generates an electronic coupon to be provided to the target user.

Apparatus, method, and computer-readable recording medium for providing information based on information elements identified by using user history information and estimated viewing duration information

A point storage unit stores points, which are imparted to the user in an electronic commerce, in association with user identification information. A link request receiving unit receives a link request for linking user identification information and membership card identification information for identifying a membership card for receiving points imparted at an actual shop. In a case where the link request is received, a link information storage unit stores link information indicating a link between the user identification information and the membership card identification information. In a case where a point use request with a designation of the membership card identification information is received, a use permission unit permits use of the points stored in association with the user identification information linked to the membership card identification information.

A commercial transaction management device includes a coupon creation control unit that receives a coupon issuance request containing sales terms when purchasing a plurality of items together from one user, a determination unit that determines whether to accept the sales terms based on information from a shop related to the items, and an issuance unit that issues an electronic coupon when it is determined to accept the sales terms. This enables an offer of a coupon that matches a desire of one user. In addition, the commercial transaction management device further includes a purchase receiving unit that receives a purchase order of a plurality of items with the sales terms from another user having received an offer of the coupon from one user, and therefore other users can also purchase a plurality of items with the sales terms contained in the coupon.

An electronic endoscope has a video-scope with an image sensor, a light source, a signal reading processor, a shading member, a driver, and a driving controller. The signal reading processor alternately reads odd-line image-pixel signals and even-line image-pixel signals over one-frame reading interval, when forming a still image on the basis of one frame worth of image-pixel signals generated by a one-time exposure. The shading member blocks the illuminating light. The driver selectively arranges the shading member at a non-shading position that enable the illuminating light to pass and at a shading position that blocks the light. The driving controller controls the driver by a sequence of pulse signals so as to position the shading member at the shading position for a shading-interval in the one-frame reading interval, and so as to position the shading member at the non-shading position for a remaining reading-interval.

An electronic endoscope has a light source that radiates illuminating light, a movie-image processor, a still-image processor, an image-change processor, and provisional image displayer. The still-image processor that alternately reads odd-line image-pixel signals and even-line image-pixel signals over two field interval to generate a still image on the basis of one frame worth of image-pixel signals generated by a one-time still image exposure. The illuminating light being blocked for a latter filed interval in the two field interval. The image change processor switches between a performance of the movie-image processor for displaying the movie-image and a performance of the still-image processor for displaying the still-image. While the still-image processor reads the odd-line and even-line image-pixel signals over the two field intervals, the provisional image displayer displays a provisional image on the basis of at least one of odd-field image-pixel signals and even-field image-pixel signals, which are obtained by an exposure before the still image exposure.
