There is provided an imaging device including: a signal processing unit configured to cause a series of picture data being continuously acquired to be temporarily stored in a buffer memory area in a signal processing process, read out the series of picture data from the buffer memory area, and perform a subsequent signal processing; and a control unit configured to perform control for deleting at least a part of the picture data stored in the buffer memory area, on a basis of detecting a predetermined operation while the signal processing is being performed on the series of picture data by the signal processing unit.

An electronic device, such as a digital camera, includes a deletion mode whereby a camera/electronic device user can delete captured images or data files that have already been transferred in order to make room in the electronic device or digital camera memory for capturing further images. In one embodiment, a digital camera keeps track of which images have already been transferred to an external storage device and presents those to the user as potential images to be deleted. In another embodiment, the user is presented with a delete all transferred images which when selected deletes all the captured images that have already been transferred. In still another embodiment, deletion criteria are used to prioritize which images are deleted first.

An information processing device includes a retaining unit and an image display. The retaining unit retains image-formation-related information of an image forming apparatus that forms an image. The image display causes a display section of a portable terminal having the display section and an image capturing section to display an image for assisting with an operation of the image forming apparatus based on a captured image result of the image capturing section and the image-formation-related information retained in the retaining unit.

An information processing apparatus that can be connected to information terminals and a data storage device through a network, and includes: a storage request receiver that receives conference identification information, information terminal identification information for a user participating in the conference, conference material data, and a storage request of the conference material data; an authentication program generator that generates an authentication program for determining whether the conference material data is capable of being transmitted to any of the information terminals when the conference material data is transmitted to the information terminal based on correspondence information in which pieces of the information terminal identification information are at least correlated with respective pieces of conference identification information, in accordance with the storage request; and a storage controller that stores the conference material data contained in the storage request and the authentication program in the data storage device in a correlated manner.

A printing system includes: a main printer configured to print an image sheet by sheet; a sub printer communicably connected to the main printer and configured to print an image sheet by sheet; and a storage medium that is configured to store image data of a plurality of images and from which the main printer is able to read out the image data. In response to changing of a state of the sub printer, the sub printer notifies the main printer of a changed state. The main printer regularly checks print situations of the main printer and the sub printer. In accordance with the print situations that are regularly checked, the main printer determines which of the printers is to be used for printing of an image for each of the image data of the plurality of images.

A device to be managed by a management device, the device includes a processor that receives selection of an item of device information to be transmitted to the management device out of device information of a plurality of items on the device; and a communication IF that transmits only device information of the selected item to the management device. The device further includes a display control section that displays a service provided in accordance with the selection of the device information.

A printer is caused to perform a checking print for a job in a case that a predetermined user's instruction is received via a user interface. The printer is caused to perform the checking print for the job without receiving the predetermined user's instruction in a case that the job meets a predetermined condition.
