Claims

[Scope of utility model registration request]

A color difference ratio data forming circuit that outputs color difference ratio data indicating the ratio of each color difference signal formed based on each color signal and luminance signal of the photographed output obtained by photographing a subject to which multiple markers of different hues are attached. an address data generation circuit that outputs address data corresponding to each pixel on the photographed image based on the synchronization signal of the photographic output, and a storage circuit that stores each color difference ratio data indicating each hue of each of the markers;
A coincidence detection circuit detects coincidence between each color difference ratio data stored in the storage circuit and the color difference ratio data output from the color difference ratio data forming circuit, and a coincidence detection circuit detects a coincidence between each color difference ratio data stored in the storage circuit and the color difference ratio data output from the color difference ratio data forming circuit, and and an address data detection circuit that detects in synchronization with each coincidence detection output of the coincidence detection circuit, detects each of the markers based on color difference ratio data, and outputs each address data indicating each position on the photographed image. A multi-point detection device characterized by:
