Abstract: An image providing system capable of quickly providing a plurality of different cropped images is disclosed. The image providing system acquires position information about a position of a user designated by the user. The image providing system determines a range of an image that was captured by an image capturing unit, the range corresponding to the position information as a cropping range, before the image capturing unit starts a series of image capturing in which the image capturing unit captures a plurality of images. After the series of image capturing is started, the system applies cropping that cuts out a part of a captured image based on the cropping range. During the series of image capturing, the system provides a cropped image to which the cropping has been applied in a way in which a user can obtain the cropped image.

Abstract: The present invention is capable of spontaneously providing a status notification to an external device in an appropriate manner. To achieve this aim, the external device, upon establishing communication with a communication apparatus, makes a status notification request to the communication apparatus, the status notification request being a request for a response that, when a change occurs in an internal status of the communication apparatus, indicates the change. Also, upon making a request to serve as a remote camera to the communication apparatus via a user interface, the external device makes a status notification request to the communication apparatus, regardless of whether or not a response has been made to the first request.

Abstract: A communication apparatus specifies content to be transmitted to an external apparatus, out of pieces of content recorded in a recording medium, and when there is a plurality of specified pieces of content, transmits first content out of the plurality of pieces of content to the external apparatus, and after the transmission of the first content, receives a notification of receipt of the first content from the external apparatus, and when the notification is received, deletes the first content from the recording medium, and after the deletion of the first content, transmits second content out of the plurality of pieces of content to the external apparatus.

Abstract: The present invention enables a data obtaining apparatus to select data to be transferred without maintaining a communication connection through close-proximity wireless communication. Accordingly, when a digital camera is communicatively connected to an external device through close-proximity wireless communication, a central processor of the digital camera obtains, from the external device, index information indicating a list of data stored in the external device. Next, the central processor terminates the communication connection to the external device and receives a designation of data to be transferred via an operation unit based on the index information. After having designated data to be transferred, an image processing unit of the digital camera obtains designated data from the external device when the camera is communicatively reconnected to the external device through close-proximity wireless communication.
