Description

The present invention relates to display bodies.

Conventionally, a display body that is displayed on a display surface that is at least one of the inner peripheral surface and the outer peripheral surface of a tubular member or a display surface that is the outer peripheral surface of a shaft member is known (for example, patent Reference 1).

WO2004/014733

The barcode (display body) described in Patent Document 1 is displayed on the display surface, which is the inner peripheral surface of the paper tube 101 (cylindrical member). When an image is captured obliquely by the image capturing means, the display captured in the captured image by the image capturing means becomes too small toward the center of the cylindrical member, and the captured display is encoded as a barcode. There is a problem that the captured content (predetermined information) cannot be read by the imaging means.

An object of the present invention is to prevent the captured display body from becoming too small toward the central portion of the cylindrical member even when the display body is imaged obliquely and captured into the captured image. It is to provide a display body.

The present invention employs the configurations described in the claims.

According to the present invention, the display body in which the reference image is stretched in the first direction is displayed on the display surface. It is possible to prevent it from becoming too small as it goes.
Further, the reference image is stretched by increasing the ratio of stretching in the first direction from the ends of the tubular member or the shaft-shaped member toward the central portion of the tubular member or the shaft-shaped member. By displaying, it is possible to reliably prevent the display body captured in the captured image by the imaging means from becoming too small toward the central portion of the cylindrical member or the shaft-shaped member.
Further, the reference image is stretched by increasing the stretching rate in the second direction orthogonal to the first direction from the end of the tubular member or shaft-shaped member toward the central portion of the tubular member or shaft-shaped member. By displaying in such a state, it is possible to reliably prevent the display body captured in the captured image by the imaging means from becoming too small toward the central portion of the cylindrical member or the shaft-shaped member.
Further, if the display body is displayed so that the reference image is stretched in the second direction, the display body captured in the captured image by the imaging means becomes smaller toward the central portion of the cylindrical member or shaft-shaped member. It is possible to more reliably prevent overshoot.
