BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a camera having a display device. More particularly, the present invention relates to a camera having a liquid crystal display (LCD) that is switched from a date display to a photographic film count display. This allows the photographic film count to be easily seen.  
           [0003]    2. Description of the Related Art  
           [0004]    Liquid crystal displays (LCDs) are often used to inform a photographer of photographing information of a camera. These displays can include a date display that displays year/month/date and a photographic film count display that displays the number of the frame of the film to be photographed. The date display and the photographic film count display are simultaneously displayed on the same liquid crystal display device. By doing so, however, there is a possibility that a part of the date display can be mistaken as a photographic film count display and vice versa.  
         SUMMARY OF THE INVENTION  
         [0005]    It is an object of the present invention to provide a camera having a display device that is easy to switch between a date display and a photographic film count display.  
           [0006]    It is another object of the present invention to provide a camera in which the date display and count display are easy to see.  
           [0007]    To achieve the above-mentioned objects of the present invention, the present invention provides a display device for a camera comprising display means including a multiple section display for displaying data in a specified direction and as embodied herein the data includes at least a photographic film count. Control means is provided to control the display means for displaying the photographic film count in the center of the multiple section display. The multiple section display is also used for displaying a date. The date and film count are displayed during different control operations. Thus, the size of the overall area for the multiple section display becomes smaller and the photographic film count display is easy to see.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0013]    Reference will now be made in detail to the present preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings.  
         [0014]    [0014]FIG. 1 is a block diagram of a display device for a camera according to the preferred embodiment of the present invention. A driving circuit  103  is provided for a liquid crystal display  104  to drive the liquid crystal display  104 . The driving circuit  103  is controlled by a CPU  102 . Main switch (SW)  101  is used to operate the CPU  102 .  
         [0015]    [0015]FIG. 2 is a diagram of the liquid crystal display  104 . In FIG. 2, the camera is in a state where main switch  101 , which enables shooting operations, is turned OFF. At this time, the liquid crystal display  104  is controlled by the CPU  102  to display a date. A multiple section display  1  includes sections  1 a,  1 b and  1 c which indicate year, month, and day, respectively. Each section includes a two-digit segment. The display format of each section is switchable. For example, from month/day/year to day/month/year to day/hour/minute. Each display format is read from left to right by changing modes using a mode switch (not shown). A display section  2 , a display section  3 , and a display section  4  indicate a light emitting mode of the speed of a flash. A display section  5  indicates a red-eye reduction mode. A display section  6  indicates a forced infinity distance mode. A display section  7  indicates a self-timer mode. A display section  8  indicates a remaining charge availability for batteries, and a display section  9  indicates whether or not the state of imprinting is activated.  
         [0016]    [0016]FIG. 3 is a diagram showing the liquid crystal display  104  when the main switch  101  is in an ON state. In FIG. 3, the number of the photographic frame (the photographic film count) is displayed in the middle of the liquid crystal display  104 . The display is changed with every photographic operation, e.g., every time a picture is taken.  
         [0017]    [0017]FIG. 4 is a flow chart explaining the operations related to the preferred embodiment of the present invention. Operation of the display is started when the main switch  101  is operated. It is determined at step SI whether or not the main switch  101  is turned ON. If the main switch  101  is ON, the CPU  102 , at step S 2 , directs a count of the frame of film to be photographed to be displayed at the multiple section display  1 , thereby displaying the state shown in FIG. 3. If it is determined at step S 1  that the main switch  101  is OFF, the CPU  102 , at step S 3 , directs a date to be displayed in the multiple section display  1 , thereby displaying the state shown in FIG. 2.  
         [0018]    If the photographic film count is displayed on the left or right side of the multiple section display  1 , it may be difficult to see the count from a diagonal direction. Consequently, if the photographic film count is displayed in the center of the multiple section display  1 , as in the preferred embodiment of the present invention and shown in FIG. 3, the photographic film count is easy to see. In this embodiment of the present invention, since the photographic film count is displayed in the center of the multiple section display  1  which is comprised of at least three two-digit segments, the count is extremely easy to see.  
         [0019]    As described above, according to the present invention, a single display for separately displaying a date and a photographic film count is effective even as the liquid crystal becomes smaller, thereby reducing cost. Also, since the photographic film count display is easy to see, the operability of the camera is improved.  
         [0020]    Although a preferred embodiment of the present invention has been shown and described, it will be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
