Abstract

The present disclosure provides techniques for translating input camera commands to device-specific commands. Camera commands may be translated by a translation engine located separately from the camera and then transferred to the camera. The translated commands may be less complex than input commands. By translating the commands, older cameras may be capable of supporting newer commands which are not natively supported.

Claims

1. An apparatus for translating imaging device commands, comprising a processor, the processor to:

determine if a translation code is available using a metadata directory;

retrieve the translation code from a metadata storage to form a translation engine in response to the translation code being available in the metadata directory;

receive imaging device commands in the translation engine;

translate the imaging device commands using the translation engine, wherein the translation engine translates imaging device commands to commands specific to a configuration of a camera subsystem; and

transfer the translated imaging device commands to an imaging device to cause the behavior requested by the translated imaging device command, wherein a camera command set (CCS) enables commands to manage the metadata storage and a metadata retrieval, and is to enable a host controller including the processor to interface with, support, and validate any camera configuration via a common set of commands defined by the CCS.

2. The apparatus of claim 1, wherein the metadata directory is a directory of metadata stored in various system data stores.

3. The apparatus of claim 1, wherein metadata of the metadata directory comprises at least one of translation code, calibration data, tuning data, imaging device firmware, or any combination thereof.

4. The apparatus of claim 1, further comprising logic to determine if the received commands are natively supported by the imaging device.

5. The apparatus of claim 1, wherein the metadata storage is located within the imaging device.

6. The apparatus of claim 1, wherein the metadata storage is located within a platform storage coupled to a host device.

7. The apparatus of claim 1, wherein the translation engine is located remotely from the imaging device.

8. The apparatus of claim 1, wherein the translation engine is located on an interposer device, and the code store is located on at least one of the interposer device, a host device, a sensor, or any combination thereof.

9. The apparatus of claim 1, wherein the translation engine translates imaging device commands to CSI-3 Attribute Get/Set commands.

10. The apparatus of claim 1, wherein the translation engine additionally translates imaging device commands to CSI-2 register read/write commands.

11. The apparatus of claim 1, wherein the translation engine translates commands that are not natively supported by the imaging device.
