an event determination section which determines in what shooting opportunity a plurality of image data items are shot and acquired based on (1) information indicative of times and dates when the image data items are acquired and (2) whether the image data items include a person; a display section which displays a plurality of kinds of events as shooting opportunities; and a control section which, when a specific event is selected from the plurality of kinds of events, causes the display section to display a first image data item relating to the selected specific event, retrieves a second image data item including a person who is included in the first image data item from the image data items relating to unselected events, and causes the display section to display the retrieved second image data item together with the first image data item. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the second image data item is given priority; and the control section includes a priority determination section which preferentially retrieves the second image data item given the priority, when the second image data item including the person who is included in the first image data item is retrieved. ### Claim 3 (depends on 2) The display apparatus according to claim 2, wherein the priority determination section determines an oldest image data item of the image data items corresponding to the specific event as the second image data item. ### Claim 4 (depends on 2) The display apparatus according to claim 2, wherein the priority determination section lowers the priority given to an image data item that has been played back in a playback mode. ### Claim 5 (depends on 2) The display apparatus according to claim 2, wherein: the priority relates to the times and dates and a face of the person; and the priority determination section sets the priority of the times and dates higher than the priority of the face of the person. ### Claim 6 (depends on 1) The display apparatus according to claim 1, wherein the control section reduces the second image data item in size, and causes the reduced second image data item to be displayed outside a frame of the first image data item. ### Claim 7 (depends on 6) The display apparatus according to claim 6, wherein the control section causes the second image data item to be displayed outside the frame so as not to conceal the face of the person. ### Claim 8 (depends on 1) The display apparatus according to claim 1, further comprising an imaging apparatus including the control section, wherein: the imaging apparatus acquires the plurality of image data items by a shooting operation; and the control section performs image classification of the plurality of image data items based on information on the plurality of image data items acquired by the imaging apparatus, and determines whether the person is included in each of the plurality of image data items from results of the image classification. ### Claim 9 (depends on 1) The display apparatus according to claim 1, wherein the unselected events of the plurality of kinds of events are events on a day other than a day when the specific event occurs. ### Claim 10 A method for retrieving and displaying similar image data items from a plurality of image data items, the method comprising: determining in what shooting opportunity a plurality of image data items are shot and acquired based on (1) information indicative of times and dates when the image data items are acquired and (2) whether the image data items include a person; displaying a plurality of kinds of events as shooting opportunities in a display section; when a specific event is selected from the plurality of kinds of events, displaying a first image data item relating to the selected specific event; retrieving a second image data item including a person who is included in the first image data item from the image data items relating to unselected events; and displaying the retrieved second image data item together with the first image data item. ### Claim 11 (depends on 10) The method for retrieving and displaying similar image data items from a plurality of image data items according to claim 10, wherein: the second image data item is given priority; and the second image data item given the priority is preferentially retrieved, when the second image data item is retrieved. ### Claim 12 (depends on 11) The method for retrieving and displaying similar image data items from a plurality of image data items according to claim 11, wherein an oldest image data item of the image data items corresponding to the specific event is determined as the second image data item. ### Claim 13 (depends on 11) The method for retrieving and displaying similar image data items from a plurality of image data items according to claim 11, wherein the priority given to an image data item that has been played back in a playback mode is lowered. ### Claim 14 A non-transitory recording medium which stores a computer-processable display program, comprising: determining in what shooting opportunity a plurality of image data items are shot and acquired based on (1) information indicative of times and dates when the image data times are acquired and (2) whether the image data items include a person; displaying a plurality of kinds of events as shooting opportunities in a display section; when a specific event is selected from the plurality of kinds of events, displaying a first image data item relating to the selected specific event; retrieving a second image data item including a person who is included in the first image data item from the image data items relating to unselected events; and displaying the retrieved second image data item together with the first image data item. ### Claim 15 (depends on 14) The non-transitory recording medium which stores a computer-processable display program according to claim 14, wherein: the second image data item is given priority; and the second image data item given the priority is preferentially retrieved, when the second image data item is retrieved. ### Claim 16 (depends on 15) The non-transitory recording medium which stores a computer-processable display program according to claim 15, wherein an oldest image data item of the image data items corresponding to the specific event is determined as the second image data item. ### Claim 17 (depends on 15) The non-transitory recording medium which stores a computer-processable display program according to claim 15, wherein the priority given to an image data item that has been played back in a playback mode is lowered.
