1. An image taking system, comprising:
a lens apparatus;
a first operating apparatus; and
a second operating apparatus,
wherein the first operating apparatus and the second operating apparatus each are configured to output a command information for driving an optical member which is movable and is included in the lens apparatus,
wherein the lens apparatus comprises:
a driving unit for driving the optical member; and
a lens controller for controlling the driving unit based on the command information from the first operating apparatus and the second operating apparatus,
wherein the first operating apparatus comprises:
an operating unit to be operated by an operator; and
a demand controller for outputting, to the lens controller, information for driving the optical member based on an operation amount of the operating unit, and
wherein the demand controller cuts off a communication connection with the lens controller when the operating unit is not being operated, and outputs position command information for the optical member to the lens controller based on the operation amount of the operating unit after the communication connection with the lens controller is established when the operating unit is being operated.
2. An image taking system according to claim 1,
wherein the lens apparatus further comprises a position detector for detecting a position of the optical member, and
wherein the demand controller generates the position command information based on a position of the optical member detected by the position detector and the operation amount of the operating unit.
3. An image taking system according to claim 2,
wherein, when the optical member is driven based on position command information from the second operating apparatus, the lens controller outputs the position command information from the second operating apparatus to the demand controller of the first operating apparatus, and
wherein the demand controller does not generate the position command information when a difference between the position command information from the second operating apparatus and the position of the optical member detected by the position detector falls outside a predetermined range.
4. An image taking system according to claim 3,
wherein the first operating apparatus further comprises a displaying unit for displaying that the optical member is being driven according to the command information from the second operating apparatus, and
wherein the demand controller causes the displaying unit to display an information indicating whether or not the difference between the position command information from the second operating apparatus and the position of the optical member detected by the position detector falls within the predetermined range.
5. An operating apparatus for outputting a command information for driving an optical member movable in a lens apparatus, comprising:
an operating unit to be operated by an operator; and
a controlling unit for outputting, to the lens apparatus, information for driving the optical member based on an operation amount of the operating unit,
wherein the controller cuts off a communication connection with the lens apparatus when the operating unit is not being operated, and outputs a position command information for the optical member to the lens apparatus based on the operation amount of the operating unit after the communication connection with the lens apparatus is established when the operating unit is being operated.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for manipulating screen objects on a display screen comprising:
providing a first screen object with a plurality of regions of influence, wherein said plurality of regions of influence comprises a plurality of overlapping screen areas;
providing a first functionality associating said first screen object and a second screen object, wherein said first functionality comprises functionality for automatically aligning said first screen object and said second screen object, said first screen object being a first audio signal graphical representation and said second screen object being a second audio signal graphical representation;
invoking a first action on said first functionality when said second screen object is moved to within a first region of influence of said plurality of regions of influence;
invoking a second action on said first functionality when said second screen object is moved from said first region of influence to a second region of influence; and
invoking a third action on said first functionality when said second screen object is moved from within said second region of influence to within said first region of influence.
2. The method of claim 1, wherein said first screen object further comprises an icon image representation of a first computer file.
3. The method of claim 1, wherein said a plurality of regions of influence comprises a plurality of concentric bands of screen areas.
4. The method of claim 1, wherein said plurality of regions of influence comprises a plurality of juxtaposed screen areas.
5. The method of claim 1, wherein said plurality of regions of influence comprises a plurality of reference data and a plurality of screen locations.
6. The method of claim 5, wherein said plurality of screen locations further comprise at least one pixel.
7. The method of claim 6, wherein said plurality of screen locations further comprise a line.
8. The method of claim 1, wherein invoking said first action on said first functionality comprises activating said first functionality to associate said first screen object with said second first screen object.
9. The method of claim 8, further comprising invoking said first functionality when said second object is moved within said first region of influence after said invoking of said first action.
10. The method of claim 1, wherein invoking said second action on said first functionality comprises deactivating said first functionality.
11. The method of claim 10, wherein invoking said second action on said first functionality further comprises activating a second functionality to associate said first screen object with said second first screen object.
12. The method of claim 11, wherein activating said second functionality comprises invoking said second functionality when said second screen object is moved within said second region of influence.
13. The method of claim 12, wherein invoking said third action comprises deactivating said second functionality.
14. The method of claim 12, wherein invoking said third action on said first functionality comprises reactivating said first functionality.
15. A computer program product embodied in a tangible computer readable medium, and comprising computer instructions for:
providing a first screen object with a plurality of regions of influence, wherein said plurality of regions of influence comprises a plurality of overlapping screen areas;
providing a first functionality associating said first screen object and a second screen object, wherein said first functionality comprises functionality for automatically aligning said first screen object and said second screen object, said first screen object being a first audio signal graphical representation and said second screen object being a second audio signal graphical representation;
invoking a first action on said first functionality when said second screen object is moved to within a first region of influence of said plurality of regions of influence;
invoking a second action on said first functionality when said second screen object is moved from said first region of influence to a second region of influence; and
invoking a third action on said first functionality when said second screen object is moved from within said second region of influence to within said first region of influence.
