Abstract:
1. An image determining device comprising: a frequency band signal detecting unit for dividing an image indicated by an image signal into a plurality of local regions and detecting for each local region signals of a plurality of frequency bands from the image signal; an average value calculating unit for calculating an average value of a characteristic value corresponding to an amplitude, for each local region and for each signal of the plurality of frequency bands detected by the frequency band signal detecting unit; a local region selecting unit for selecting at least one local region based on image information of one or more image signals; an average value selecting unit for selecting the average value corresponding to the local region selected in the local region selecting unit; a relative value calculating unit for calculating a relative value of one average value with respect to another average value, both of the average values being of the average values for each of the plurality of frequency bands selected in the average value selecting unit; and an image determining unit for determining an image based on the relative value calculated by the relative value calculating unit.
