Subsequently, a display target area corresponding to the imaging range indicated by the imaging range information is set in an image captured by the camera section. Then, a partial image in the display target area in the image captured by the camera section is displayed on the monitor. As a result, live view display can be achieved without causing the imaging device to capture a photographic subject at a predetermined frame rate and transmit the captured image. ## Claims ### Claim 1 A display device comprising: an imaging section; a display section; an acquiring section which acquires imaging range information indicating an imaging range for an external imaging device; a setting section which sets, in an image captured by the imaging section, an area corresponding to the imaging range indicated by the imaging range information acquired by the acquiring section; and a first display control section which controls an image corresponding to the area set by the setting section to be displayed on the display section. ### Claim 2 (depends on 1) The display device according to claim 1, further comprising: a communication section which performs communication with the external imaging device, wherein the acquiring section acquires the imaging range information from the external imaging device via the communication section. ### Claim 3 (depends on 2) The display device according to claim 2, wherein the communication section sequentially receives, from the external imaging device, images captured by the external imaging device, and wherein the first display control section controls the images sequentially received by the communication section to be displayed on the display section. ### Claim 4 (depends on 1) The display device according to claim 1, wherein the external imaging device is structured to be removably attached to a device main body. ### Claim 5 (depends on 4) The display device according to claim 4, further comprising: a confirming section which confirms whether the external imaging device has been attached to the device main body, wherein the first display control section controls images sequentially received by the communication section to be displayed on the display section on condition that the confirming section has confirmed that the external imaging device has been attached to the device main body. ### Claim 6 (depends on 5) The display device according to claim 5, further comprising: a requesting section which requests the external imaging device via the communication section to start imaging operations that are performed at predetermined time intervals and start transmission of images captured by the imaging operations, in response to confirmation by the confirming section that the external imaging device has not been attached to the device main body. ### Claim 7 (depends on 5) The display device according to claim 5, wherein the confirming section judges that the external imaging device has been attached when the imaging range indicated by the imaging range information acquired by the acquiring section is included in an imaging range of the image captured by the imaging section. ### Claim 8 (depends on 2) The display device according to claim 2, wherein the acquiring section requests the external imaging device via the communication section to perform an imaging operation and transmission of an image captured by the imaging operation, and acquires the image transmitted from the external imaging device as the imaging range information in response to the request. ### Claim 9 (depends on 2) The display device according to claim 2, wherein the setting section specifies an area corresponding to a first image acquired as the imaging range information by the acquiring section, based on contents of a second image captured by the imaging section at same or substantially same timing with the first image, and sets the specified area as the set area. ### Claim 10 (depends on 9) The display device according to claim 9, wherein the setting section specifies the area corresponding to the first image in the second image by searching the second image for a specific area corresponding to a reference area defined in advance in the first image, and sets the specified area as the set area. ### Claim 11 (depends on 9) The display device according to claim 9, further comprising: a second display control section which controls such that the first image acquired as the imaging range information by the acquiring section and the second image captured at the same or substantially same timing with the first image are displayed on the display section in a manner to be identifiable; and an adjusting section which adjusts a display position and size of the first image in response to an external operation after display by the second display control section, wherein the setting section specifics the area corresponding to the first image in the second image based on a result of adjustment of the first image by the adjusting section, and sets the specified area as the set area. ### Claim 12 A display method comprising: an acquiring step of acquiring imaging range information indicating an imaging range for an external imaging device; a setting step of setting, in an image captured by an imaging section, an area corresponding to the imaging range indicated by the imaging range information acquired in the acquiring step; and a display control step of controlling an image in the area set in the setting step to be displayed on a display section. ### Claim 13 A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer in a display device having an imaging section and a display section, the program being executable by the computer to actualize functions comprising: acquisition processing for acquiring imaging range information indicating an imaging range for an external imaging device; setting processing for setting, in an image captured by the imaging section, an area corresponding to the imaging range indicated by the imaging range information acquired in the acquisition processing; and display control processing for controlling an image corresponding to the area set in the setting processing to be displayed on the display section.
