OG exemplary drawing
 
1. An image processing device comprising:
a brightness image creating portion configured to create a brightness image showing a brightness distribution in a color image captured by a camera;
a saturation image creating portion configured to create a saturation image showing a saturation distribution in the color image;-ate
an analyzed image creating portion configured to create an analyzed image for detecting a predetermined target by synthesizing the brightness image and the saturation image; and
an extracted image creating portion configured to create a saturation extracted image in which a drawing pattern larger than a detection target is removed from the saturation image by performing a contraction process and an expansion process to the saturation image, wherein
the analyzed image creating portion is configured to create the analyzed image by synthesizing the saturation extracted image instead of the saturation image and the brightness image.
