<p>PURPOSE:To catch and display a group of targets having some feature. CONSTITUTION:The density distribution of a target is calculated at a section 26 based on an image data on an image memory 14. A CPU section 18 designates a density value or a density range for a density distribution calculating section 26 where a group of targets having that density value or belonging to that density range is taken out and the position thereof is determined, The CPU section 18 calculates the range where the position calculated at the section 26 belongs and delivers the information of characters or figures representative of the calculation results to a display control section 16. Information representative of the distribution range of a group of targets, for example, is presented on the screen of a display 12.</p> |
