My VPCSB Vaio shows the camera as 'USB 2.0 Camera' in Device Manager and shows the driver as USBVIDEO.SYS which is a Windows 7 generic driver and is part of the Windows 7 installation.. My built -in webcam is not capable of zoom or pan but it is an older model than yours.
I think your webcam is working as it should. Where did you get the information that it can zoom and pan?
In the Webcam Companion 4 software when you click capture, then webcam settings, then advanced.., then camera control. The camera control settings are greyed out. These include the zoom and pan etc. It would be helpful to me if you could see if yours are greyed out too.
Do you not find that odd, to show possible settings, but not give you the option to change them? I had a Sony laptop prior to this one (5 years old) and it could zoom and pan the image.
Not really, the software in question is third-party, generic stuff designed for use with any webcam you can buy - including large bolt on cameras that do have the ability to pan and zoom. It is not Sony software.
To be fair, nowhere do Sony claim that the webcam has these functions and I don't know any Notebook that does. What model Vaio did you have before?
