Abstract

The present disclosure provides techniques for executing a command within a transport mechanism based on a get and set architecture. An attribute identification of the command is extracted and a get protocol data unit (PDU) is sent from a host device to a imaging device based on the attribute identification in order to obtain attribute values from an image source within the imaging device. Additionally, a response PDU is sent from the imaging device to the host device to complete the execution of the command.

Claims

1. An apparatus for executing a command using command transport, comprising:

a controller to encapsulate a protocol data unit of the command encapsulated in an attribute packet, to send the encapsulated protocol data unit to an imaging device, and to receive a status value in a response protocol data unit from the imaging device to complete the command; and

wherein the command corresponds to a CSI-3 Attribute.

2. The apparatus of claim 1, wherein the imaging device comprises a camera and the command is a camera command.

3. The apparatus of claim 1, wherein the protocol data unit is a get protocol data unit.

4. The apparatus of claim 1, wherein the apparatus comprises a host device.

5. The apparatus of claim 1, the controller to extract an attribute identification of the command, and to send the protocol data unit based on the attribute identification.

6. The apparatus of claim 1, wherein a sensor of the imaging device executes the command when the protocol data unit is sent to the imaging device.

7. The apparatus of claim 1, wherein a sensor of the imaging device executes the command when the protocol data unit is sent to the imaging device without blocking.

8. The apparatus of claim 1, wherein the controller is to encapsulate the protocol data unit in a CSI-3 Attribute Packet and then send it to the imaging device.

9. The apparatus of claim 1, wherein the response protocol data unit includes attribute values obtained from an image source within the imaging device.

10. The apparatus of claim 1, the controller to obtain attribute values from an image source of the imaging device.

11. The apparatus of claim 10, wherein the image source is an image sensor, a system on a chip (SOC) imaging device, a multichip imaging device module or an image signal processor (ISP).

12. The apparatus of claim 1, the controller further to receive a notify protocol data unit from the imaging device, wherein the notify protocol data unit does not include attribute values based on the attribute identification from the command.

13. The apparatus of claim 1, the controller further to send a set protocol data unit to the imaging device, wherein the set protocol data unit is to write attribute values to the imaging device based on attribute identification from the command.

14. An imaging device for executing a command using command transport, comprising:

a controller to receive a protocol data unit of the command encapsulated in an attribute packet, and to return a status value in a response protocol data unit to complete the command; and

wherein the command corresponds to a CSI-3 Attribute.

15. The imaging device of claim 14, wherein the protocol data unit is received from a host device and the response protocol data unit is sent to the host device.

16. The imaging device of claim 14, wherein the imaging device comprises a camera and the command is a camera command.

17. The imaging device of claim 14, wherein the received protocol data unit is a get protocol data unit.

18. The imaging device of claim 14, wherein the received protocol data unit is based on attribute identification extracted from the command.

19. The imaging device of claim 14, further comprising a sensor to execute the command when the protocol data unit is received.

20. The imaging device of claim 14, further comprising a sensor to execute the command when the protocol data unit is received without blocking.

21. The imaging device of claim 14, wherein the received protocol data unit is encapsulated in a CSI-3 Attribute Packet.

22. The imaging device of claim 14, further comprising an image source, wherein the response protocol data unit includes attribute values obtained from the image source.

23. The imaging device of claim 22, wherein the image source is an image sensor, a system on a chip (SOC) imaging device, a multichip imaging device module or an image signal processor (ISP).

24. The apparatus of claim 22, wherein the image source is a RAW imaging device sensor, a system on a chip imaging device, a multichip imaging device module or an image signal processor.

25. The apparatus of claim 22, the controller further to send a notify protocol data unit, wherein the notify protocol data unit does not include attribute values based on the attribute identification from the command.

26. The imaging device of claim 22, the controller further to receive a set protocol data unit, and to write attribute values based on attribute identification from the command.

27. A system for executing a command using command transport, comprising:

a host comprising a controller to encapsulate a protocol data unit of the command encapsulated in an attribute packet, to send the encapsulated protocol data unit, and to receive a status value in a response protocol data unit from the imaging device to complete the command; and

an imaging device comprising a controller to receive the encapsulated protocol data unit from the host, and to return the status value to the host in the response protocol data unit to complete the command; and
