Abstract

In accordance with some embodiments, a protocol permits communications between platforms and image devices. This allows, for example, the platform to specify particular types of information that the platform may want, the format of information the platform may prefer, and other information that may reduce the amount of processing in the platform. For example, conventionally, in gesture recognition software, the platform receives an ongoing stream of video to be parsed, searched and processed in order to identify gestures. This may consume communications bandwidth between platforms and imaging devices, particularly in cases where wireless communications or other bandwidth limited communications may be involved.

Claims

1. A method comprising:

sending a message from a platform and to an image capture device to specify a format of image data and what image data is to be transferred from the device to the platform related to an image to be displayed on said platform, wherein said message includes what depicted objects to look for in image data, what metadata to return, and how often to return the metadata;

receiving image data in the platform; and

processing the received image data on said platform.

2. The method of claim 1 including transferring instructions from a platform to a camera to specify processing to be done in the camera before transferring image data to a platform.

3. The method of claim 1 including sending a message from a platform to a display device to arrange for data provided to the display device to be placed in a particular format.

4. The method of claim 1 including establishing a bidirectional protocol for exchanging information about image data between a platform and an image capture device.

5. The method of claim 1 including using pre-established commands to specify characteristics of information exchanged for processing of image data between a platform and an image capture device.

6. The method of claim 1 including offloading the processing of image data from a processor to a peripheral by providing commands to the peripheral to perform processing on the peripheral before transferring image data to the processor.

7. One or more non-transitory computer readable media storing instructions that cause a computer to:

send a message from a platform and to an image capture device to specify a format of image data and what image data is to be transferred from the device to the platform related to an image to be displayed on said platform, wherein said message includes what depicted objects to look for in image data, what metadata to return, and how often to return the metadata;

receiving image data in the platform; and

process the received image data on said platform.

8. The media of claim 7 further storing instructions to transfer instructions from a platform to a camera to specify processing to be done in the camera before transferring image data to a platform.

9. The media of claim 7 further storing instructions to exchange messages between a platform and a display device to arrange for data provided to the display device to be placed in a particular format.

10. The media of claim 7 further storing instructions to establish a bidirectional protocol for exchanging information about image data between a platform and an image capture device.

11. The media of claim 7 further storing instructions to use pre-established commands to specify characteristics of information exchanged for processing of image data between a platform and an image data.

12. The media of claim 7 further storing instructions to offload the processing of image data from a processor to a peripheral by providing commands to the peripheral to perform processing on the peripheral before transferring image data to the processor.

13. An apparatus comprising:

a processor to send a message from a platform to an image capture device specifying an image data format and what image data is to be transferred from the device to the apparatus related to an image to be displayed on said apparatus, wherein said message includes what depicted objects to look for in image data, what metadata to return, and how often to return the metadata, to receive image data on said apparatus in the format specified in said message, and process the received image data on said platform; and

a memory coupled to said processor.

14. The apparatus of claim 13 wherein said apparatus is a cellular telephone.

15. The apparatus of claim 13, said processor to send a message to a camera specifying an image data format for data from said camera.

16. The apparatus of claim 13, said processor to send the message over a bidirectional protocol for exchanging image data.

17. The apparatus of claim 16, said processor to use pre-established commands with said image device.

18. The apparatus of claim 13 said processor to offload an image processing task to an image device using said message.

19. The apparatus of claim 13 said processor to provide data to a display in a format specified in a message received from said display.
