1. An image viewing system comprising plural mobile terminals and a large display apparatus connected to each other via a network, each of the mobile terminals including: a memory unit configured to store one or more pieces of image data; an input receiving unit configured to receive a predetermined input for displaying on the large display apparatus an image indicated by a piece of image data selected by a user from among the one or more pieces of image data; and a display instructing unit configured to issue a first instruction to the large display apparatus to display on the large display apparatus the image indicated by the piece of image data selected by the user, based on the input received by the input receiving unit, and the large display apparatus including: a large display; an arbitrating terminal determining unit configured to determine, as an arbitrating terminal, one of the mobile terminals connected to the large display apparatus via the network, the arbitrating terminal being a terminal which performs arbitration for determining a manner in which the images indicated by the first instructions are to be displayed on the large display; a first display control unit configured to display on the large display the images indicated by the first instruction issued by the display instructing unit of each of the mobile terminals; and a display instruction receiving unit configured to receive the first instruction issued by the display instructing unit of each of the mobile terminals, wherein the large display apparatus determines whether or not at least two first instructions, issued by at least two mobile terminals including the arbitrating terminal among the mobile terminals, are received, wherein the first display control unit of the large display apparatus is configured to, when it is determined that the at least two first instructions are received, (a-1) display on the large display a first image based on the first instruction issued by the arbitrating terminal, and (a-2) display on the large display a second image based on each of the at least two first instructions issued by the at least two mobile terminals except the arbitrating terminal, in a second size smaller than a first size in which the first image is displayed, wherein the display instructing unit of the arbitrating terminal determined by the arbitrating terminal determining unit is further configured to perform the arbitration by (i) receiving the first instruction issued by the display instructing unit of each of the mobile terminals, and (ii) issuing, after the images indicated by the first instructions have been displayed on the large display, a second instruction to the large display apparatus to cause the first display control unit to change the manner in which the images are displayed on the large display, and wherein the arbitrating terminal determining unit is configured to determine, as the arbitrating terminal, one of the mobile terminals whose connection status with the network satisfies a predetermined condition.
