A microprocessor having a processor core includes an information acquisition unit that acquires information encrypted to be used by the processor core, from outside; a decryption unit that decrypts the information with a symmetric key to obtain plain text; and a controller that controls processing on the information acquired by the information acquisition unit based on the symmetric key. An image processing device includes a variance calculation unit that obtains a variance of an area consisting of a target pixel and neighboring pixels included in a first frame, and changes, according to the variance, the rate at which an error generated at the target pixel through tone level restriction is distributed within the frame and between frames. A lever is connected to the frame and a connection member is connected between the movable board and the lever. In addition, the systems and methods are further configured for assigning a certification to an entity associated with the evaluated packages based on the results of the evaluation.
