Claims

[Claims for Utility Model Registration] A display means that performs a scanning display with a sweep time to obtain a predetermined brightness based on a periodic signal obtained by reflecting a pulse signal by the object. A display processing device that outputs data for displaying an image regarding the periodic signal, the display processing device comprising: converting means for digitizing the periodic signal; and a plurality of converters for respectively writing and reading data strings for each pulse signal output from the converting means. storage means; selection means for selecting one of the storage means in a predetermined order corresponding to the order of pulse signals corresponding to the data string; and among the data strings output from the conversion means,
data reading for sampling the number of pictures necessary for display on the display means and writing these sampled data strings into the storage means selected by the selection means in real time when the periodic signal arrives; and, within the period of the periodic signal, after reading data into any of the storage means, read data strings in parallel from each of the plurality of storage means in correspondence with the sweep time of the display means. 1. A display processing device comprising: a data readout means for reading data; and a correlation means for determining a correlation between a plurality of data strings read by the data readout means.
