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 within a transport mechanism based on a get and set architecture, comprising:

a processor, a memory, logic stored in the memory and to be executed by the processor comprising;

logic to extract an attribute identification of the command;

logic to send a get protocol data unit (PDU) 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; and

logic to send a response PDU from the imaging device to the host device to complete the execution of the command.

2. The apparatus of claim 1, wherein a sensor of the imaging device executes the command when the get PDU is sent from the host device to the imaging device.

3. The apparatus of claim 1, wherein a sensor of the imaging device executes the command when the get PDU is sent from the host device to the imaging device without blocking.

4. The apparatus of claim 1, wherein the get PDU is encapsulated in a CSI-3 Attribute Packet and then sent to the imaging device.

5. The apparatus of claim 1, wherein the response PDU includes attribute values obtained from an image source within the imaging device.

6. The apparatus of claim 1, 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).

7. The apparatus of claim 1, further comprising logic to send a notify PDU from the imaging device to the host device, wherein the notify PDU is does not include attribute values based on the attribute identification from the command.

8. The apparatus of claim 1, further comprising logic to send a set PDU from the host device, wherein the set PDU writes attribute values to the imaging device based on the attribute identification from the command.

9. A system for executing a command within a transport mechanism based on a get and set architecture, comprising:

a host device; and

an imaging device coupled to the host device, wherein a get protocol data unit (PDU) is sent from the host device to the imaging device and the get PDU includes a request for attribute values from an image source of the imaging device, the attribute values based on attribute identification to be extracted from the command, and wherein a response PDU is sent from the imaging device to the host device to complete the execution of the command.

10. The system of claim 9, wherein a sensor of the host device executes the command when the get PDU is sent from the host device to the imaging device.

11. The system of claim 9, wherein, wherein a sensor of the imaging device executes the command when the get PDU is sent from the host device to the imaging device without blocking.

12. The system of claim 9, wherein an image source is RAW imaging device sensor, an system in a chip imaging device, a multichip imaging device module or an image signal processor.

13. The system of claim 9, wherein a notify PDU is sent from the imaging device to the host device, wherein the notify PDU is not on does not include attribute values based on the attribute identification from the command.

14. The system of claim 9, wherein a set PDU is sent from the imaging device to the host device, wherein the set PDU reads or writes attribute values to the imaging device based on the attribute identification from the command.

15. A tangible, non-transitory, computer-readable storage medium having computer-executable instructions for executing a command within a transport mechanism based on a get and set architecture, the instructions causing a computer to:

extract an attribute identification of the command;

send a get protocol data unit (PDU) 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; and

send a response PDU from the imaging device to the host device to complete the execution of the command.

16. The tangible, non-transitory, computer-readable medium of claim 15, wherein the get PDU is encapsulated in a CSI-3 Attribute Packet and then sent to the imaging device.

17. The tangible, non-transitory, computer-readable medium of claim 15, wherein the response PDU includes attribute values obtained from an image source within the imaging device.

18. The tangible, non-transitory, computer-readable medium of claim 15, wherein the image source is RAW imaging device sensor, an system in a chip imaging device, a multichip imaging device module or an image signal processor.

19. The tangible, non-transitory, computer-readable medium of claim 15, wherein a notify PDU is sent from the imaging device to the host device, wherein the notify PDU is not on does not include attribute values based on the attribute identification from the command.

20. The tangible, non-transitory, computer-readable medium of claim 15, wherein a set PDU is sent from the imaging device to the host device, wherein the set PDU writes attribute values to the imaging device based on the attribute identification from the command.
