A signal processing circuit uses gate signals corresponding to a plurality of divided measurement ranges to extract a fine particle pulse signal from a light reception level signal generated by an optical pickup, count the pulse number for each of the gate signals, and output a count value for each of the divided measurement ranges. A count value in-plane distribution generating unit generates count value in-plane distribution data in a measurement range based on the count value. A reaction region position coordinate computation unit estimates positions of all reaction regions from the count value in-plane distribution data. A reaction region count value computation unit calculates the count values for each of all the estimated reaction regions.

A determiner determines execution of rerouting. A notifier notifies the execution of rerouting if the determiner determines the execution of rerouting. A searcher executes a rerouting search if the determiner determines the execution of rerouting. A measurer measures the distance by which a navigation device has moved along a guide route, which is a result of the rerouting search by the searcher. In a case in which the determiner determines execution of next rerouting, the notifier notifies the execution of rerouting if the measured distance is longer than a threshold value and does not notify the execution of rerouting if the measured distance is smaller than or equal to the threshold value.

On a display device, a lenticular lens is arranged in a state where a periodic direction thereof is inclined with respect to the horizontal direction. Within a maximum predetermined viewing angle defined by two viewpoint images with the largest parallax, a viewpoint adjustment unit sets a first angular region where there is a high possibility that one or more eyes may be present when an observer observes the display device, and a second angular region where there is a low possibility that one or more eyes may be present. The viewpoint adjustment unit adjusts the viewpoints so that a parallax between adjacent viewpoint images in viewpoint images to be presented in the first angular region is reduced more than a parallax between adjacent viewpoint images in viewpoint images to be presented in the second angular region.
