Abstract

PURPOSE: To easily extract an object area on the color picture of a complicate scene by interactively designating the range of the distribution of the area to be extracted according to the distribution state of plural two dimensional histograms.
CONSTITUTION: A two dimensional histogram forming means 3 reads picture data by one picture element from a picture memory 2, calculates the distribution frequency of the combination of the two colors of the picture element and writes in a two dimensional histogram memory 4. A display device 5 displays the contents of the picture memory 2 and the two-dimensional histogram memory 4. A pointing device 6 refers to the displayed color picture and the two-dimensional histogram to designate the representative point of a picture and a two-dimensional threshold and a color coordinate detecting means 8 calculates a position on a two-dimensional color plane corresponding to the representative point of the picture designated by the pointing device 6 and extracts the picture area according to the contents of a two-dimensional threshold memory 7. Thereby, the specific object area can be extracted interactively from the picture of the complicate scene.
