Abstract

A controller for use in generating signals for enabling control of a plurality of functions of a camera and lens assembly comprising a movable member having a first region adapted to be engaged by a user'"'"'s first finger for moving the movable member in a plurality of directions to develop first and second signals for controlling first and second functions of the camera and lens assembly, and at least a plurality of further regions with each of the further regions being finger reachable by another finger of the user when the user'"'"'s first finger is engaging the first region and being adapted to be finger actuatable to develop a signal for enabling control of a further function of the camera and lens assembly.

Claims

1. A controller for use in generating signals for enabling control of a plurality of functions of a physical device, the controller comprising:

a housing;

a movable disc movably supported by said housing, said movable disc having a movable disc assembly including a movable disc and a linkage assembly for supporting said disc for lateral and longitudinal movement; and

said movable disc having a first region adapted to be engaged by a first finger of a hand of a user for moving the movable disc in a plurality of directions, said movement of said movable disc being used to develop first and second signals for control of first and second functions of said physical device; and

at least a plurality of further regions, each of said further regions being finger reachable by another finger of said hand of said user when said first finger of said user is engaging said first region and being adapted to be finger actuatable to develop a further signal for control of a further function of said physical device.

2. A controller in accordance with claim 1, further comprising:

first means for generating said first and second signals responsive to the movement of said movable disc;

and second means responsive to actuation of each of said further regions for generating a further signal.

3. A controller in accordance with claim 2, wherein:

said first region comprises a first surface area of said movable disc;

and said further regions each comprise a further surface area of said movable disc adjacent to said first surface area.

4. A controller in accordance with claim 3, wherein:

said first surface area includes an indentation for seating said first finger;

and each of said further surface areas includes a button supported in and accessible through an aperture in the further surface area.

5. A controller in accordance with claim 2, wherein:

said physical device is a surveillance assembly including a camera and lens assembly;

said functions of said physical device include panning and tilting of said camera and lens assembly; and

focus, zoom and iris control of said camera and lens assembly;

said first and second functions are said panning and tilting functions;

said further functions include two or more of said focus, zoom and iris functions.

6. A controller in accordance with claim 2, wherein:

said linkage assembly includes first and second pivotally mounted arms each having a central slot and arranged so that the central slots of said first and second arms overlap;

and said disc includes a shaft which is captured in said central slots of said first and second arms where said central slots overlap.

7. A controller in accordance with claim 6, wherein:

said movable disc assembly includes means for returning said pivotally mounted arms to a neutral position upon release of finger engagement to said disc.

8. A controller in accordance with claim 7, wherein:

said movable disc assembly further includes means for providing an audible indication when each of said pivotally mounted arms is returned to its neutral position.

9. A controller in accordance with claim 6, wherein:

said first arm extends longitudinally and is pivotally mounted so as to undergo lateral displacement;

said second arm extends laterally and is pivotally mounted so as to undergo longitudinal displacement;

and said means for generating said first and second signals includes;

first detecting means for detecting the lateral displacement of said first arm; and

second detecting means for detecting the longitudinal displacement of said second arm.

10. A controller in accordance with claim 9, wherein:

said first signal is indicative of the speed of control of said first function based upon the degree of detected lateral displacement;

and second signal is indicative of the speed of control of said second function based upon the degree of detected longitudinal displacement.

11. A controller in accordance with claim 2, wherein:

said first and second signals are indicative of the speed of control of said first and second functions based upon the degree of lateral and longitudinal movement of said movable disc, respectively.

12. A controller in accordance with claim 2, wherein:

each said further signal is indicative of the speed of control of the corresponding further function based upon the length of time of actuation of the further region used to develop the further signal.

13. A controller in accordance with claim 2, further comprising:

a microcomputer responsive to the signals from said first and second means for developing control signals based thereon.

14. A controller in accordance with claim 13, further comprising:

a non-volatile memory for storing program code for said microcomputer.

15. A controller in accordance with claim 14, wherein:

said non-volatile memory comprises one of a RAM and an EEPROM.

16. A controller in accordance with claim 1, wherein:

the housing has a bottom wall, said bottom wall is contoured upward for placement on the leg of the user.

17. A controller in accordance with claim 1, wherein:

the housing has a top wall, said top wall has a centrally located recessed area; and

said movable disc is supported in said recessed area.

18. A controller in accordance with claim 16, further comprising:

an inclined keypad supported on an end of said housing forward of said movable disc.

19. A controller in accordance with claim 18, wherein:

the top wall of said housing is contoured rearward of said movable disc to form a palm rest.

20. A controller in accordance with claim 19, wherein:

said contoured top wall palm rest has grooves.

21. A controller in accordance with claim 18, wherein:

said keys of said keypad on the right half of said keypad and said keys of said keypad on the left half of said keypad are symmetric and provide like control.
