1. An information display apparatus comprising: a processor configured to acquire an image, in which first objects are arranged in a row on a second object, to recognize identification information on each of the first objects and a position, in the acquired image, of each of the first objects, as well as a point on the second object and a position, in the acquired image, of the point, and to set the recognized point on the second object as an origin point; storage configured to store identification information of one of the first objects, which is a reference object, and identification information of another one of the first objects, which is a target object and arranged in a same row with the reference object, and a first rule indicating a positional relationship, which includes a relative position, a relative direction and a direction vector, between the reference object and the target object, in advance on an object-to-object basis in respect of each of the first objects; and a display, wherein the processor is further configured to at least: determine, based on the origin point, whether or not the position in the acquired image, of the reference object satisfies the first rule by using the position of the reference object and the position in the acquired image of the target object; if the position of the reference object is determined to satisfy the first rule, create a determination image indicating that the position of the reference object satisfies the first rule, and, if the reference object is determined not to satisfy the first rule, create a determination image indicating that the position of the reference object does not satisfy the first rule; create a display image for display on the display by superimposing the created determination image on the reference object in the acquired image; wherein the storage further stores identification information of the second object and a second rule specifying the positional relationship of the first rule by using a two-dimensional coordinate system based on the origin point; and the processor is further configured to recognize the origin point and the positions, in the acquired image, of the reference and target objects and to determine whether or not the position, in the acquired image, of the reference object satisfies the positional relationship of the first rule specified by the second rule in the coordinate system, by using the position of the second object, the position of the reference object, and the position of the target object.
