  This embodiment will be described with reference to FIGS. In the present embodiment, an image projection system 101 installed in a store space 102 of a retail store and using a wall surface 104 as a reflective screen will be introduced.

  FIG. 1 is a schematic diagram showing an outline of an image projecting method realized by the image projecting system 101. A plurality of display shelves 105 are provided on the wall surface 104 of the store space 102 according to the store space 102. The commodity 103 sold to the customer C is displayed in a state where it is placed on the display shelf 105. Then, for example, the customer C who has made a purchase visits the in-store passage 106 provided along the display shelf 105, examines the product 103 displayed on the display shelf 105, and hands over the product 103 to be purchased. After putting it in the shopping basket, he goes to a cashier counter (not shown) and conducts a merchandise accounting transaction.

  On the wall surface 104 located above the display shelf 105 and at a height that the customer C cannot reach but can be looked over, the shape of the projection area 109 that is elongated in the lateral direction fits the store space 102 Is provided. The projection area 109 is provided for displaying a content image PV including content that the store wants to appeal to the customer C. The display of the content image PV in the projection area 109 is realized by the image projection system 101 installed in the store.

  The image projection system 101 includes a projector 107 and an optical unit 108. What is important here is that the content image PV is projected onto the projection area 109 as a result of rearranging the projection image S of one screen configuration projected from the projector 107 into a shape different from the original projection image S by the optical unit 108. It is what is displayed. The projector 107 is attached to the attachment mechanism 110 installed on the ceiling of the store above the projection area 109. The projector 107 is attached to the attachment mechanism 110 with the image projection port 107a facing the in-store passage 106. The projector 107 is powered by a power supply cord (not shown), and is connected to the control device 113 through a LAN cable 112 so as to be capable of data communication. The control device 113 transmits to the projector 107 image data that is the basis of the projection image S of one screen configuration projected by the projector 107 and a control command for controlling the image projection of the projector 107. When the projector 107 receives image data or a control command transmitted from the control device 113, the projector 107 projects a projection light beam 111 corresponding to the image data from the projection port 107 a toward the optical unit 108. The optical unit 108 is installed and installed at a location facing the projector 107 across the in-store passage 106, for example, a wall surface 104 or a ceiling (not shown). As another example, the optical unit 108 is an independent mounting unit (not shown) for mounting another display shelf (not shown) installed in a store or the optical unit 108 installed on the floor surface. It may be attached to. As the projection area 109, a part of the wall surface 104 may be used, or a screen that matches the shape of the projection area 109 may be employed.

The case where the image data of the projection image S including the second partial image S2 for displaying the column “ABC” in the projection area 109 in the lower stage is received is shown. These character strings “ABC” and “DEF” are elements constituting the content image PV. The projector 107 projects a projection image S having a single screen configuration based on the received image data from the projection port 107 a in accordance with a control command transmitted from the control device 113. The projection image S is reflected on the projection area 109 as an image adjacent in the horizontal direction after the first partial image S1 and the second partial image S2 included therein are individually reflected by the optical unit 108. A series of character strings “ABCDEF” is displayed. As described above, according to the image projection system 101 of the present embodiment, the projection area of the projector 107 (generally, a rectangular projection area having an aspect ratio of 3 to 4 and 9 to 16) is different in the horizontal direction. Display of a long large content image PV can be realized with a simple structure.

  FIG. 2 is a schematic diagram of image data that is the basis of the projection image S of the projector 107. The image data transmitted from the control device 113 to the projector 107 is a basis for the projection image S of the projector 107. The projected image S includes a first partial image S1 and a second partial image S2. The first partial image S1 is positioned above the second partial image S2 in the projection image S having a single screen configuration. Each of the first partial image S1 and the second partial image S2 has a rectangular shape, and has an aspect ratio that is longer than the aspect ratio of the entire projection image S. Further, in the image projection system 101 of the present embodiment, the optical unit 108 is configured by a plane mirror as will be described later, and is projected and displayed on the projection area 109 functioning as a reflective screen, so that the projection image S is reversed left and right.
