Imaging system and method for interactive control of image quality
First Claim
Patent Images
1. An imaging system for interactively adjusting image quality parameters associated with an image transmission, said imaging system comprising:
- a sending device for receiving a plurality of images from said image transmission and for transmitting said plurality of images;
a receiver device, connected to said sending device, for receiving said plurality of images transmitted from said sending device, said plurality of images being transmitted from said sending device to said receiver device along a forward channel, said plurality of images transmitted to said receiver device including a plurality of said image quality parameters associated with said plurality of images; and
an interface, connected to said receiver device, for receiving a non-normative command to modify at least one of said plurality of image quality parameters, said non-normative command being forwarded by said interface to said sending device along a backchannel thereto, whereby a viewer of a display device, connected to said receiver device, interactively adjusts said at least one image quality parameter of subsequent images via said non-normative command input to said interface, wherein a measurement parameter is associated with said non-normative command for defining a valid duration during which said non-normative command is operable to adjust said at least one image quality parameter.

Abstract
An improved imaging system and method for providing increased viewer control over the operating parameters of the imaging system is described. Viewer control is facilitated by including a backchannel within the imaging system, whereby a viewer may adjust spatial and temporal resolution, quantization and other operating parameters of the video transmission.

-
a sending device for receiving a plurality of images from said image transmission and for transmitting said plurality of images;
a receiver device, connected to said sending device, for receiving said plurality of images transmitted from said sending device, said plurality of images being transmitted from said sending device to said receiver device along a forward channel, said plurality of images transmitted to said receiver device including a plurality of said image quality parameters associated with said plurality of images; and
an interface, connected to said receiver device, for receiving a non-normative command to modify at least one of said plurality of image quality parameters, said non-normative command being forwarded by said interface to said sending device along a backchannel thereto, whereby a viewer of a display device, connected to said receiver device, interactively adjusts said at least one image quality parameter of subsequent images via said non-normative command input to said interface, wherein a measurement parameter is associated with said non-normative command for defining a valid duration during which said non-normative command is operable to adjust said at least one image quality parameter. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. In an imaging system, a method for interactively adjusting image quality parameters associated with an image transmission within said imaging system, said method comprising the steps of:
-
receiving a plurality of images from said image transmission in a sending device;
transmitting said plurality of images from said sending device to a receiver device, said transmission including therein a plurality of said image quality parameters associated with said plurality of images;
receiving a non-normative command from said receiver device to adjust at least one of said plurality of image quality parameters, said non-normative command having a measurement parameter associated therewith for defining a valid duration during which said non-normative command is operable to adjust said at least one image quality parameter;
receiving at least one image quality parameter associated with the non-normative command to adjust at least one image quality parameter setting, the at least one image quality parameter operable to adjust balance between the respective associated plurality of said image quality parameters;
adjusting at least one image quality parameter setting; and
adjusting at least one respective associated plurality of said image quality parameters prior to said transmission via a backchannel communication from said receiver device to said sending device if said non-normative command is within said valid duration, whereby image transmissions to a display device, connected to said receiver device, subsequent to said adjustment incorporate said adjusted image quality parameters. - View Dependent Claims (10, 15, 16, 17, 18, 19, 20)

11. The method according to claim 11, further comprising, after said step of receiving and before said step of transmitting, the step of:
-
encoding, within said sending device, said plurality of images into a corresponding encoded signal. - View Dependent Claims (12, 13, 14)
decoding, within said receiver device, said encoded signal into the corresponding plurality of images.

21. A method for increased viewer control, in an imaging system, over image quality parameters associated with an image transmission within the imaging system, the viewer control being facilitated through an interface coupled to a control unit, the method comprising the steps of:
-
receiving a non-normative command to interactively adjust at least one of the image quality parameters of a subsequent image;
receiving at least one measurement parameter associated with the non-normative command to adjust the at least one of the image quality parameters, the at least one measurement parameter operable to adjust said at least one image quality parameter for a finite duration specified by a user;
adjusting the at least one image quality parameter for the finite duration; and
transmitting an image having the adjusted at least one image quality parameter for said finite duration. - View Dependent Claims (22, 23, 24, 25, 26)
