Claims

[Scope of utility model registration request]

In a display device that superimposes and displays the own ship's track from logs, gyroscopes, etc., net depth gauge position display marks, etc., in addition to the fish school image by horizontal sonar, the fish school image, the own ship's track, and a vertical cross section from a depth sounder are displayed. The display screen of the display device is divided into a flat display part and a vertical section display part, and the flat display part has a group of memory elements that separately store data such as images, and the display screen of the display device is divided into a flat display part and a vertical section display part. The memory element is configured to display one net depth gauge position display mark, etc., and display the net depth position at a position corresponding to the net depth gauge position display mark in addition to the fish school and seabed images on the vertical section display section. What is claimed is: 1. An underwater object image display device comprising: a superimposition display circuit that reads out a plurality of images from a group, superimposes the images, and outputs the superimposed images to the display device, thereby displaying a three-dimensional positional relationship of underwater objects.
