Abstract: A ship information displaying system can easily grasp the size of a ship intuitively. The system includes a position detector that detects a position of a ship and generates positional data, a direction detector that detects a heading of the ship and generates directional data, a memory that stores size data indicative of a flat dimension of the ship on the basis of a detected location of the positional data in the ship, processing circuitry that places a ship object indicative of the ship at a position in a virtual three-dimensional space corresponding to the positional data, with an orientation corresponding to the directional data and a size corresponding to the size data and that generates an image containing the ship object by rendering a scene based on a viewpoint position and a line-of-sight direction set in the virtual three-dimensional space, and a display that displays the image.

Abstract: A data processing apparatus that can set the magnification factor according to the distance from the antenna is provided so that the display of objects close to the antenna is easier to see and with which the changes in the settings of the magnification factor is easy. The buffer memory stores the digital signals converted by the A/D converter in association with the distance and azimuth with respect to the antenna. The digital filter filters the digital signals read from the buffer memory. A digital filter is provided that converts a value of data of interest, of digital data stored in the memory, to a value based on values of the data of interest to be processed and peripheral data in a periphery of the data of interest, and the digital filter changes a range of the peripheral data used for a filter processing according to the distance from the antenna to the data of interest.
