To provide an image detecting method for determining whether or not a specific image exists in an input image, an input image signal is temporarily held, data is acquired from a holding data such as a circle having a radius r, And determines whether or not the feature value is included in the specific pattern according to the similarity between the feature value and the reference feature value. If the feature value is included in the specific pattern, a circle having a radius r 'different from the radius r , Calculates a new feature value, and repeats the operation of determining whether or not it is included in a specific pattern for the original data having a plurality of radii. This makes it possible to effectively detect whether or not an arrangement condition of a specific image such as an angle and a position in the input image exists.
