1. An electronic camera, comprising: an image sensor; a rangefinding unit; a first arithmetic operation unit that calculates a characteristic quantities based upon pixel density in an image obtained via the image sensor and rangefinding information obtained via the rangefinding unit; a second arithmetic operation unit that selects a characteristic quantity group with characteristic quantities closest to the characteristic quantities calculated by the first arithmetic operation unit, among a plurality of characteristic quantity groups classified in advance in a space in which the characteristic quantities are expressed; a third arithmetic operation unit that judges a photographic scene corresponding to the characteristic quantity group selected by the second arithmetic operation unit; a control unit that selects camera settings in correspondence to the photographic scene having been judged; and a storage unit that stores characteristic quantity variance/covariance information for each of the classified characteristic quantity groups, wherein: the second arithmetic operation unit selects a characteristic quantity group corresponding to the variance/covariance information indicating a value closest to a characteristic quantity calculated within the space by the first arithmetic operation unit.
