    Abstract: A video camera having a zoom function and a camera system are provided, wherein a ratio of view fields of the video camera and a photographic camera is calculated based on information about zooming powers of imaging lenses, and an image frame of the photographic cameras is displayed in a variable size at an electronic viewfinder in accordance with the ratio of the view fields and based on a picked-up image of fixed size, or a picked-up image is displayed in a variable size on the basis of the image frame of the photographic camera. View angles of the video camera and the photographic camera are obtained from the information about the zooming powers of the imaging lenses, and zoom adjustment is carried out with the view angles coinciding with each other, or the zooming power of one of the video camera and the photographic camera is adjusted such that the view angles become equal to each other. Accordingly, the view field of the photographic camera can be accurately recognized even if the zooming power is changed.

    Abstract: The reading timing determination unit determines a timing at which identification marks such as print bar codes should be read. The reading unit reads identification marks in accordance with the timing to provide identification mark data in a numerical form. The discrimination unit compares identification mark data with data value of an identification mark to be primarily printed to judge whether or not the identification mark is correctly printed. The signal generation unit produces a notifying signal when it is judged that the identification mark is not correctly printed. In this way, this apparatus tests whether or not identification marks successively printed on a moving body in the form of sheet by the printing machine are correctly printed.
