As the automation of cameras have developed to a great extent recent years, a camera with an automatic focus unit and an automatic exposure unit comes into common use. Recently, however, higher functions such as short focusing time and improvement of focusing precision have been more and more demanded. In addition to the above, a demand has been made of a camera with alarge-size display unit which is capable of visualizing at a glance a variety of information on photographing, such as complicated and various program exposure modes such as a shutterspeed priority mode for a telephotographic lens and an object depth priority mode for a wide angle lens, the number of pictures photographed, a program mode, and so on.
At this end, there has been developed a camera having a liquid crystal display mounted to a main body of the camera so as to display exposure modes such as manual, auto, program, bulb exposure and so on or a shutter speed or the number of pictures photographed or the like.
Although a mode at the time of photographing can be altered by operation of a select switch while visualizing information on the camera displayed on the liquid crystal display, however, such a camera suffers from the disadvantages 1 that information displayed on the display is visualized in a too small size and it is hard to carry out operation at the time of setting a mode.
SUMMARY OF THE INVENTION
Therefore, the present invention has been performed to solve the problems involved with conventional cameras and has the object to provide a display system of a camera which allows information on the camera to be displayed on a display unit in 10such a manner as capable of being readily visualized and which has an improved operability at the time of setting a photographing mode and other modes.
In order to achieve the object, the present invention consists of a display system of a camera for displaying 15photographing data or information relating to the camera on a display unit disposed in -a main body of the camera, wherein: the photographing data or information is divided into sub-title data or information to be displayed by a plurality of sub-titles and subordinate data or information to the sub-title data or 20information; and which comprises: a information display changeover means for selecting and displaying the sub-title data or information and the subordinate data or information on the display unit.
As the above arrangement for the display system of the 25camera permits a display of the sub-title information concerning a photographing mode or the like displayed on the display unit by altering the subtitle information in order by a simple operation, the photographer can find out desired sub-title information quickly and readily while visualizing the sub-tile information on 30the display unit at the time of setting a mode. Further, when the 1 photographer has selected the desired sub-title information, detail information concerning the desired sub-title information selected can be displayed quickly on the display unit so that visualizability can be improved, together with operability, thereby lightening the burden to be otherwise imposed on the photographer at the time of setting a mode.

The present invention will now be described more in detail by way of examples in conjunction with the accompanying drawings.
A control circuit of the camera to which the display system according to the present invention is applied will now be described with reference to FIGS. I and 4.
The camera 2f has an automatic focus (AF) unit, an automatic loading, winding and rewinding unit, an automatic exposure (AE) unit, and so on, and its basic operation is carried out in substantially the same manner as conventional is cameras. The camera 21 is further provided on a pentagonal roof prism unit 21a (FIG. 4) with a dot liquid crystal display (LCD) 23 for displaying data or information on the camera.
The control circuit has a control microcomputer 39 for controlling the dot LCD 23 and a central processing unit (CPU) 24 to which electric power in turn is supplied from a battery 25 thr_ough a regulator 26. The control circuit further contains a lock switch 28, a photometric switch 29, and a release switch 30. When the lock switch 28 and the photometric switch 29 or the release switch 30 are turned on, a PI joint of the-CPU 24 is arranged so as to become a low level, thereby starting up a DC/DC converter 61 and supplying electric power to each unit. In FIG. 1, reference numeral 27 2-5 denotes a super capacitor (condenser) which serves as competing with a rapid drop of the voltage of the battery 25. Further, in the drawing, reference numeral 31 denotes a charge-coupled device (CCD) image sensor, reference numeral 32 denotes a CCD treating circuit, reference numeral 33 denotes a switch box, reference numeral 34 denotes a light a -13emitting diode, and reference numeral 35 denotes an in-lens read-only memory (ROM). As shown in FIG. 1, a display box 36 contains a row drivers 37a and 37b, a dot liquid crystal display (LCD) 23, and column drivers 38a and 38b. The LCD 5 control microcomputer 39 is connected to the CPU 24 through a bus 40 and has a built-in displaying random access memory (RAM) which is designed so as to transmit data to the column drivers 38a and 38b in a constant cycle and generating a timing signal to both the row drivers 37a and 37b followed by driving the dot LCD 23.
From the CPU 24 to the LCD control microcomputer 39, there is transmitted display data on the basis of a transfer clock SCK1 through the bus 40. The display data includes various ones such as, for example, exposure mode Tv, Av,ISO, and Xv.
More specifically, the displaying RAM of the LCD control microcomputer 39 converts the data transferred from the CPU 24 into a display RAM data for displaying on the dotLCD 23. In this case, data of a character generator 41 is referenced as needed.
The data of the character generator 41 is transferred to the LCD control microcomputer 39 through a bus 42 on the basis of a transfer clock SCK2. This data is then given a logical add, together with the displaying RAM data, thereby providing a final display RAM data. A display RAM bit with respect to this data corresponds to one bit in the dot LCD 23.
1 The displaying RAM data is transferred in a constant cycle to the column drivers 38a and 38b by means of the timing signal generated by the LCD control microcomputer 39.
Chip selector CSO and CS1 of the respective row drivers 37a and 37b, as shown in FIG. 2, are terminals for selecting which column driver 38a or 38b has the data written.
As the LCD control microcomputer 39 generates a STB 5 signal to the row driver 37a or 37b after the data has been written on the column driver 38a or 38b, the column driver 38a or 38b generates data corresponding to a display by one row. This allows the row driver 37a or 37b to be turned on by one row, thereby permitting a display by one row on the dot LCD 23. The repetition of this operation permits a display of each data on the dot LCD 23. In the drawing, reference alphanumerals DBO to DB7, inclusive, denote data signal lines.
FIG. 3 illustrates an example of the switch box having operating switches 51 to 56 and 76 -77 (FIG. 6) for operating the dot LCD 23, respectively. A pull-up resistance R may be disposed on the side of the CPU 24 and may be constructed so as to be pull up only when to implement switch checking.
The control microcomputer 39 is provided with a 20division display means 71, a sub-title altering means 72, a sub-title selecting means 73, a full display means 74 and a screen changeover means 100. These means has each functions acting upon the dot LCO 23 through the displaying RAM.
The division display means 71 is to divide the dot 25LCD 23 into plural regions (first region 23a, second region 23b, third region 23c and fourth region 23d, as shown in FIG. 8) and to display sub-title data or information in each of these regions. The sub-title data or information is one which displays a variety of photographing information by a plurality 30of sub-titles, and the content of the sub-title data or information is described in more detail by detail data or information located as subordinate information of the sub-title data or information.
The sub-title altering means 72 has the function of 5 displaying subtitle data or information on a screen to be switched over by operation of the corresponding switch, when the sub-title data or information cannot be displayed on the first, second, third and fourth screen of another screen because the number of the sub-title data or information is more than the number of regions of the screen to be divided by the division display means 71.
The sub-title selecting means 73 is to select either of the sub-title data or information displayed on the dot LCD 23 by the division display means when the correspond- ing switch is turned on.
The screen changeover means 100 is to display the detail data or information as subordinate data or information of the selected_sub-title data or information on the dot LCD 23 through the full.display means 24 when either sub-title- data or information is selected by the sub-title selecting means 73.
The full display means 74 has the function of combining each of the divided regions into one on the basis of the screen changeover means 100.
Description will then be made of a specific display of data or information of the dot LCD 23 which serves as a display means of the present invention.

In other words, interrupt processing into the LCO control micro5computer 39 is executed at step S6, the timer is set to 125 mS at step S7, and an A-loop is started up once at each 125 mS at step S8, followed by step S9 at which the program stops so as to allow a signal from the tinier to be interruptible. The A-loop is a main routine which intermittently (i.e. period is 10determined in step S7) performs by the operation of the timer.
At step SIO, an abnormal data subroutine is executed in order to display data on abnormal data on the screen of the dot LCD 23 and the program flow advances to step S6.
When the result of decision at step Sl indicates that the lock switch 28 is in an OFF state as described hereinabove, the program flow goes to step S11 at which signals neither from the photometric switch 29 nor from the release switch 30 can be interrupted, followed by step S12 at which a subrout-ine for a lightening-out data set for putting Out I ights of the display of the dot LCD. 23. Thereaf ter, the program flow goes to step S6.
Then, description will be made of the camera system checking subroutine at step S3 with reference to the flowchart of FIG. 23.
First, at step S13, a decision is made to determine if there is an error on the side of the CPU 24 in loading a film. Then the program flow goes to step S14 when the result of decision at step S13 indicates that no error is found on the 'side of the CPU 24 in loading the film, on the one hand, 30while the program flow advances to step S24 if the result of decision at step S 13 indicates that the loading of the film is erred on the side of the CPU 24, on the other hand.
Subsequent to step S13. a decision is made at step S14 for the purpose of determination if there is an error with respect to a voltage level of the battery. If the result of decision at step S14 indicates that no error is found in 5 the voltage level of the battery, then the program flow proceeds to step S15. If the result of decision at step S14 indicates that there is an error in the voltage level of the battery, the program flow proceeds to step S24.
When no error has been found in the voltage level of the battery as a result of the decision at step S13, then the program flow proceeds to step S15, as described hereinabove, at which a decision in turn is made to determine if there is abnormality in a film used, such as a too old film used. Then, the program flow proceeds to step S16 when the result of 15decision at step S15 indicates that there is no abnormality in the film used, while the program flow proceeds to step S27 if abnormality is found in the film used.
Then, subsequent to step S15, a decision is made at step S16 to determine if less than five sheets of films are 201eft unphotographed in the film loaded. If the result of decision at step S16 indicates that the film loaded has five or more films left yet unphotographed, on the one hand, then the program flow goes to step S17. If the result of decision at step S16 indicates that less than five films are left yet 25unphotographed in the film loaded, on the other hand, then the program flow goes to step S30.

When the result of decision at step 30S17 indicates that there is no abnormality in the functions of 1 the camera and so on, the program flows proceeds to step S18 at which a decision is made to determine if there is another abnormality, followed by step S19 when the result of decision at step S18 indicates no abnormality checked, on the one Shand, or followed by step S20 when the result of decision at step S18 indicates that there is another abnormality checked. In each case, subsequent to steps S19 and S20, the program flow is returned.
As described herei-nabove, when the program flow loproceeds to step 521 as a result of the decision at step 513 indicating an error in loading the film, checking a "users confirmation V is executed. If the screen provides an.. error'f display, i.e., a display indicating the error and the user turns a confirmation switch on, other than that 15displayed on the screen or a given time period has elapsed after the display, the program flow proceeds to step S22 at which an "abnormal data 1 is cancelled. followed by step S14. When the user turns the right confirmation switch on in accordance with the "user's confirmation 1", the program flow 20proceeds to step 523 at which an "abnormal data V is set and thereafter the program flow proceeds to step S14.
When the result of decision indicates at step S14 that there is abnormality in the voltage level of the battery, as described hereinabove, the program flow goes to step S24 25at which a "user's confirmation 2 is checked. As a result, when there is a display on the screen of the dot LCD 23. indicating an error, and the user presses the confirmation switc,h or a given time period has elapsed after the display, the program flow proceeds to step S25 at which an "abnormal 30data 2 is released followed by proceeding to step S15- If f 1 there is no display of the "user's confirmation 2" at step S24, the program flow proceeds to step 26 at which an.1 abnormal data 2" is set, thereby indicating such an abnormal display on the screen and thereafter going to step S15.
-5 When the program flow has proceeded to step S27 subsequent to step S15, a user's confirmation 3" is checked.
If there is an "error" display on the dot LCD 23 and the confirmation switch is pressed after confirmation by the user or a given period of time has passed after the display was logiven, the program flow goes to step S28 at which an.. abnormal data 3" is released followed by proceeding to-step S16. As long as the "user's confirmation 3 is not displayed on the dot LCD 23, the program flow proceeds to step S29 at which the "abnormal data 3 is set and then to step S16.
is As the program flow has proceeded to step S30 subsequent to step S16, a "user's confirmation C is checked.
If there is an "error" display on the screen of the dot LCD 23 and the confirmation switch is pressed after confirmation by the user or a given period of time has passed 20after the display was given, the program flow goes to step S31 at which an "abnormal data 4" is released followed by proceeding to step S17. As long as the "user's confirmation C is not executed at step S30, the program flow proceeds to step S32 at which the "abnormal data 4" is set, thereby 25displaying such an abnormal state on the screen of the dot LCD 23 and then proceeding to step S17.
