Hi,

We are using Fixed focus. when we checked our camera the "hasAutofocus: 1"is showing. Could you share the way of how to check the focus (fixed focus or auto focus) ?? And Can we check whether the camera we tested is fixed or auto focus from below messages?? what "hasAutofocus: 1" is meanging for?

others: {socket: RGB/CENTER/CAM_A, sensorName: IMX378, width: 4056, height: 3040, orientation: AUTO, supportedTypes: [COLOR], hasAutofocus: 1, name: color}, {socket: LEFT/CAM_B, sensorName: OV9282, width: 1280, height: 800, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, name: left}, {socket: RIGHT/CAM_C, sensorName: OV9282, width: 1280, height: 800, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, name: right}

Best regards,

Ryan.

Hi RyanLee

"hasAutofocus" only means that the camera is capable of automatically adjusting focus. There is to my knowledge no method for reading the autofocus mode of the camera. Setting the mode at start is the easiest way to ensure fixed focus is active (by default, the camera is set to CONTINUOUS_VIDEO).

Hope this helps,
Jaka

Hi RyanLee
I'm not entirely sure what you mean.
If camera is fixed focus, then hasAutofocus will be 0
If camera is auto focus, then hasAutofocus will be 1
Whether an auto focus camera is currently in AF or FF mode, you currently cannot check.

Hope this helps.

Hi RyanLee,
Yes, Oak-D color camera is AF, while Oak-D mono cameras are both FF. I believe this confirms my previous posts.

jakaskerl Thanks Jaka, i was confused. now i got your point. it means only "capable" not acutally working mode. Thanks again.

Best regards,

Ryan.
