PROBLEM TO BE SOLVED: To instantaneously detect a freeze failure even if frames of images can not be synchronized between one and two systems. SOLUTION: Feature values of the images inputted from each of a first and second systems are generated, difference of the feature values between frames of each of the first and second systems is calculated, difference of the feature values between the first and second systems is calculated and a freeze failure is determined to be generated when either one of the feature values between frames of the first or second systems is equal to or less the a prescribed value, difference of the other feature value exceeds the prescribed value and difference of the feature values between the systems exceeds the prescribed or when both of the difference of the feature value between frames in the first and second system is equal to or less than the prescribed value and the difference of the feature values between the systems exceeds the prescribed value.
