Image control device, image control system, and digital camera

Abstract

The invention is provided with: an acquisition unit that acquires, from an external machine, image data as well as time data when an image based on the image data has been displayed on the external machine; a data memory unit that stores, for each unit of the image data, the image data and the time data acquired in the acquisition unit; and a prioritization determination unit that determines, on the basis of the time data, a prioritization of the image data stored in the data memory unit.

1 . An image control device, comprising:
 an acquisition unit that acquires, from an external machine, image data as well as time data when an image based on the image data has been displayed on the external machine;   a data memory unit that stores, for each unit of the image data, the image data and the time data acquired in the acquisition unit; and   a prioritization determination unit that determines, on the basis of the time data, a prioritization of the image data stored in the data memory unit.   
     
     
         2 . The image control device according to  claim 1 , comprising:
 an image display unit that displays the image based on the image data; and   a display control unit that controls the image display unit to display the image based on the image data on the basis of the prioritization determined by the prioritization determination unit.   
     
     
         3 . The image control device according to  claim 2 , further comprising:
 a display time measurement unit that measures a display time when the image based on the image data stored in the data memory unit has been displayed on the image display unit; and   a time memory control unit that causes, for each unit of the image data, display time data relating to the display time to be stored, wherein   the prioritization determination unit determines the prioritization of the image data on the basis of the time data and the display time data.   
     
     
         4 . The image control device according to  claim 2 , further comprising:
 a display time measurement unit that measures a display time when the image based on the image data stored in the data memory unit has been displayed on the image display unit; and   a time memory control unit that causes, for each unit of the image data, display time data relating to the display time to be stored, wherein   the prioritization determination unit determines the prioritization of the image data on the basis of the display time data instead of the time data.   
     
     
         5 . The image control device according to  claim 3 , comprising: a time memory unit that stores the display time data, wherein
 the time memory control unit causes the display time data to be stored in the time memory unit.   
     
     
         6 . The image control device according to  claim 3 , wherein the time memory control unit causes the display time data to be stored as tag information of the image data. 
     
     
         7 . The image control device according to  claim 3 , wherein the time memory control unit causes information relating to types of a device which has displayed the image based on the image data to be stored in association with the display time data. 
     
     
         8 . The image control device according to  claim 3 , wherein the time memory control unit causes information indicative that the image based on the image data has been 2D-displayed or information indicative that the image based on the image data has been 3D-displayed to be stored in association with the display time data. 
     
     
         9 . The image control device according to  claim 3 , wherein the time memory control unit causes information relating to a display size of the image displayed on the basis of the image data to be stored in association with the display time data. 
     
     
         10 . The image control device according to  claim 8 , wherein the display time of a case where the image based on the image data has been 2D-displayed and the display time of a case where the image based on the image data has been 3D-displayed are interdependent. 
     
     
         11 . The image control device according to  claim 3 , wherein the time data and the display time data are data relating to a time greater than a predetermined time which is pre-set. 
     
     
         12 . The image control device according to  claim 3 , wherein the prioritization determination unit determines the prioritization of the image data on the basis of the time data and the display time data, each of which has been assigned a weighting.
