Abstract

A photographic apparatus is comprised of a plurality of adjustable units and a common digital display. The adjustable units and the common digital display are interconnected by information-transmitting circuitry. The circuitry includes selectors for selecting the unit whose setting is to be displayed on the common digital display along with an associated coordination symbol indicating which setting is being displayed.

Claims

1. In a photographic apparatus of the type comprised of a plurality of adjustable units, in combination, a common digital display means;

and information-transmitting means interconnecting the adjustable units and the common display means and operative for causing the common display means to effect a display of the setting of any selected one of the adjustable units, including selector means operative for selecting the unit whose setting is to be displayed on the common display means, the selector means comprising a plurality of display-select switch means each associated with a respective one of the adjustable units and operative when activated by the user for connecting to the common digital display means a respective one of the plurality of adjustable units.

2. In a photographic apparatus as defined in claim 1, the information-transmitting means comprising a plurality of storage means each associated with a respective adjustable unit and operative for storing information representing the setting of the respective unit and means for causing the common display means to effect a display of the information stored by any selected one of the storage means, the selector means comprising means operative for selecting the storage means whose stored information is to be displayed on the common display means.

3. In a photographic apparatus as defined in claim 2, at least some of said storage means being analog storage means operative for storing said information in analog form, the information-transmitting means further including analog-to-digital converter means operative for converting the information stored in analog form into digital form for display on the common digital display means.

4. In a photographic apparatus as defined in claim 3, the common digital display means having a predetermined number of display places for digital display of the setting of the selected adjustable unit, the analog storage means each being operative for transmitting to the analog-to-digital converter means a respective analog signal whose value varies within a predetermined range corresponding to the range of settings of the associated adjustable unit, each predetermined range being so preselected that upon conversion of the respective analog signal to digital form and display of the corresponding digital information upon the common digital display means all of said predetermined number of display places are utilized.

5. In a photographic apparatus as defined in claim 1, the common digital display means including means for digitally displaying the setting of any selected one of the adjustable units and means for displaying different coordination symbols associated with respective ones of the adjustable units, the information-transmitting means including means for causing the common display means to effect simultaneous display of both the setting of any selected one of the adjustable units and the associated coordination symbol.

6. In a photographic apparatus as defined in claim 3, at least one of said storage means being a digital storage means operative for storing said information in digital form, the information-transmitting means including decoding means connected directly between the digital storage means and the common display means and operative for decoding the digital information and effecting a corresponding display on the common digital display means.

7. In a photographic apparatus as defined in claim 1, at least some of the adjustable units being provided with manually movable adjusters, each of said manually movable adjusters being movable by the user to adjust the numerical value to which the associated one of the adjustable units is set, the selector means comprising means for automatically selecting which one of the adjustable units provided with the manually movable adjusters is actually to have its setting displayed by activating the display-select switch means associated with the unit whose setting is to be displayed in automatic response to the user performing a predetermined movement of one of the manually movable adjusters, whereby when the user touches one of the manually movable adjusters and moves it this automatically causes the adjustable unit associated with the moved adjuster to have its current setting displayed on the common digital display means.

8. In a photographic apparatus as defined in claim 7, at least some of the manually movable adjusters being capable of performing an adjusting motion changing the setting of the respective unit but not constituting said predetermined movement and also an auxiliary movement controlling an auxiliary operation not changing the setting of the respective unit, the auxiliary movement constituting said predetermined movement, whereby when the user touches one of these manually movable adjusters and performs the auxiliary movement this automatically causes the adjustable unit associated with the thusly moved adjuster to have its current setting displayed on the common digital display means.

9. In a photographic apparatus as defined in claim 7, at least some of the manually movable adjusters being capable of performing an adjusting motion changing the setting of the respective unit but not constituting said predetermined movement and also an auxiliary motion not changing the setting of the respective unit, the auxiliary motion constituting said predetermined movement, whereby when the user touches one of these manually movable adjusters and performs the auxiliary motion this automatically causes the adjustable unit associated with the thusly moved adjuster to have its current setting displayed on the common digital display means.

10. In a photographic apparatus as defined in claim 7, said predetermined movement of said manually movable adjusters being a movement changing the numerical value to which the associated one of the adjustable units is set, whereby when the user touches one of the manually movable adjusters and changes the setting of the associated one of the adjustable units this automatically causes the one adjustable unit whose setting is being changed to now have its setting displayed on the common digital display means.

11. In a photographic apparatus as defined in claim 1, the apparatus being a motion-picture apparatus, one of the adjustable units being operative for generating information indicative of the length of film remaining in the film supply unit of the apparatus, the information-transmitting means comprising means receiving the film-length information and effecting digital display thereof upon the common digital display means in units of meters.

12. In a photographic apparatus as defined in claim 1, the photographic apparatus having a housing, the common digital display means being located on the exterior of the housing.

13. In a photographic apparatus as defined in claim 1, the photographic apparatus including a viewfinder, the common digital display means being located viewable through the viewfinder.

14. In a photographic apparatus as defined in claim 5, the means for displaying different coordination symbols comprising a plurality of superimposed illuminatable elements each bearing a respective coordination symbol, the configuration and disposition of the coordination of the sumbols on the superimposed illuminatable elements being such that in the event of improper simultaneous selection of a plurality of adjustable units the fact that a plurality of associated coordination symbols are being displayed will be perceivable.

15. In a photographic apparatus as defined in claim 1, the apparatus including at least three adjustable units, the selector means accordingly comprising at least three display-select switch means, each associated with a respective one of the at least three adjustable units and each operative when activated by the user for connecting to the common digital display means the respective one of the at least three adjustable units.
